  1. funfact about the Aj260, it required a minuteman first stage srb fired downwards into the motor to evenly ignite it. One can imagine the concern at nasa had this ever gone forward with pointing one big srb up into the bottom of their 3000 ton rocket sitting ontop of their even bigger SRB.

  2. "We gotta put a fairing on top of the shuttle!" ".....why don't we just build a rocket and leave the shuttle on the ground..." "Quiet! we're building shuttles, SHUTTLES not rockets now!"
    578
  3. when you remember the guys designing this were doing so with paper, pens, and the field of nuclear physics being about 20 years old, its amazing they managed to accomplish so much
    432
  4. the dumber dumb part of hubble... the spare mirror was ground to perfection by a different company who said those other guys don't know what they're doing but their critiques were ignored due to political reasons the spare (perfect) mirror now sits in the smithsonian with a lovely plaque commemorating this billion dollar blunder
    365
  5. "And canada would provide a robotic arm." and what a fine robotic arm its been
    358
  6. you know its also possible they realized this about 10 years ago said "yikes!" and quietly switched to ceramics
    272
  7. "Ivan, what is das?!" "it is soyuz i swear!" "it has no boosters, it has too few combustion chambers, it looks too...american!" "it is... diet...soyuz, for people who think soyuz is too big for them..."
    271
  8. Everyone whos vacuumed popcorn up and clogged their vacuum understands what has happened here
    236
  9. "Presumably by the time it came home it was the longer term exposure facility" ya nasa has that kind of dry sense of humor
    225
  10. the difference is one is talking from a theoretical mega engineering perspective, the other is a politcian seriously asking if we can just move the move the moon based on spurious ideas that global warming has to do with solar cycles and tide patterns instead of his state's massive carbon output
    161
  11. I'm sure the NSA has a love/hate relationship with these companies since they provide lots of intel, but also prove that you don't have to be the NSA to afford a spy sat program
    138
  12. the anicdote about the orange wasn't as much of an over-reaction as you'd think. British military liasons were able to accurately discern that the Soviet Union's new T-72s tanks were using a 125mm gun based on one of them putting an apple in the bore then later measuring it when on a patrol in the berlin area. BRIXMIS was a weird fascinating program that wouldn't happen today
    132
  13. never thought H2 would have an ortho or para allignment state, i only ever thought things with larger structure could have different alignments
    113
  14. "Now you have a reason to crash things!" incoming danny video...
    105
  15. every kerbal veteran can appreciate RCS going nuts
    83
  16. this thing was being designed by mechanical engineering students out of college
    81
  17. Low background steel isn't needed because they switched from atmospheric oxygen to liquified oxygen for most steel production, so no radioactive contaminates
    68
  18. using rs-25s as disposable engines is such an absolute waste
    65
  19. Americans: You can't just point your rocket to the correct orbit! Soviets: Launch pad go wibble wobble!
    53
  20. I could not work in that office, I'm already distracted by my company's little cabinet of history every time I walk by it
    50
  21. funny thing, upon first contact with the kerbals, the tzan empire thought they were fierce warriors, riding their flaming ships to slam into and destroy them however after jeb finally successfully docked with them they realized that death by guidance error is quite common to kerbal spaceflight
    47
  22. SLS: Destroying dreams since 2010!
    47
  23. ya I can't see any issue with Lockheed owning Boeing's engine manufacturer for SLS
    45
  24. when the question of How many People can we actually fit in the capsule, is asked in all seriousness
    43
  25. the good thing is I think, NASA has much much better knowledge testing and understanding what they want in a space suit to write the contract
    37
  26. science cannot move forward without burned heaps of tortoises!
    36
  27. OsirisRex: "Ok I'm going! boop Guys I- why are you all wearing masks?"
    35
  28. unless they get a crewed orion up to ISS in the next 6 months they're gonna blow right past that
    35
  29.  @travcollier  the soviet space program basically didn't give them the time or budget to construct the rigs and do the testing needed to catch these problems
    32
  30. John Dee was a really strange man, like your small bit doesn't even scratch the surface.
    30
  31. An interesting concept would be to put a mechanical arm on the trunk, since in normal operation, its hollow anyways, and space-x has a lot of robot arm guys now. You could build a mission specific trunk that has an arm, and hardware bays to store mission modules
    29
  32. Aerrin Longheart i think the last patch was sometime after the dinosaurs, something to do with furless apes but theyre totally OP and are getting nerfed
    28
  33. "Look dad, I'm the Hindenberg!" SN10
    27
  34. that's such a bad story though, every flight path has a range of values instead of exact calculations, a 100 lb girl isn't going to actually impact a vessel on re-entry nearly as much as high altitude wind sheer will
    24
  35. beoing is a joke but dragon got a lot of experience and hardware out of the cargo missions too
    22
  36. 100% fratricide chance for the aries 1 lol You didn't demonstrate this classic problem in KSP i noticed. its a really common beginner mistake of too little thrust for the payload.
    22
  37. Jett Quasar soviet design tended to be so increadibly centralized that one single person was making the design decision, quality control, inspection procedures, launch conditions ect, it let them jump ahead with the r-7 and vostok but as rockets got more complicated this style became horrendously deficient as korolev's replacement was a raving alcoholic and had basically a competing space program within the soviet union. ironically this was the same thing that we did early on with vanguard and jupiter rocket programs but then we rightly recognized the need for one managable program and created NASA out of both and while it did have a director, design decisions were carried out by committee and time was taken for testing
    21
  38. from an engineer i worked with that visited them "They're a bunch of cowboys"
    18
  39. their business model was basically the 90s cellphone model.
    16
  40. The AGS was like the can of spam in the back of the pantry, you think you're never going to need it until the world ends THEN botulism.
    16
  41. the only rocket capable of launching an entire chamber of congress on an earth escape trajectory
    16
  42. not really sure how they get to mars and back on a pile of cryogenic propellants when they boil off relatively rapidly compared to the journey time Not really sure how they intend to land something that top heavy on mars (or the moon) without some sort of developed landing pad either Not really sure if the fuel bleed heat shield even works either. Additionally nobody's got a good idea of what a stainless steel space vehicle of its size does in space with regards to expansion and the million other little daunting metallurgical problems
    15
  43. "We launched first!" "We got there first!" "America!" "USSR!"
    15
  44. "The price should come down [on the RS-25]" ya sure, that's not exactly what it was made for but sure lets keep thinking that since SLS isn't just a way to slush cash into the hands of certain political donors
    14
  45. mars was certainly an inspiration but stuff like Laurence of Arabia, or the USGS Dune survey project he was working on were also inspirations
    14
  46. that long march 1 looks suspiciously like a redstone from a distance
    14
  47. but wait scott, when they used it in apollo 13, they were essentially taping up an airduct for the co2 scrubbing canisters, in that application it was duct tape
    14
  48. I always remember the dimethylmercury bit, its a potent reminder that what someone is asking for and what they want are two different potentially life saving things
    13
  49. AJ's problem was they demanded the government fund development of any new engine back 10 years ago and everybody ignored them because times were changing
    12
  50. eh you forgot to inject dimethylmercury for that extra thrust.
    12
  51. NSWR: You thought Orion was crazy look at me!
    11
  52. big question, why would they have a class A fire extinguisher on the ISS when electrical and chemical fires use a class D?
    11
  53. saturn IB and the CSM was a much cheaper and better vehicle for both low earth and possible cheaper trans lunar missions, Nixon really just wanted the space program to go away and ditched all the apollo hardware on purpose
    11
  54. well the point of the rs-25 was you reused them, but no follow on development ever followed to actually continually develop them to be more and more reusable, now we're tossing them away on each SLS launch
    11
  55. SPLITTERS!
    11
  56. I wonder if the tape is just oxidizing. it would have probably been made to be enclosed in some pressurized environment
    10
  57. so like 4 iphones from now?
    10
  58. methane flames + the metal the engines are made of + various starting chemicals like TEB that burn green
    10
  59.  @cryptolicious3738  nooooo think of the children! that's always justification for draconian intrusive policies because its for the children, and totally not for some future chinese requirement to erase people
    10
  60. 5:43 always understated how amazing the photos from voyager were
    9
  61. they tried MRI but the machine exploded
    9
  62. It occures to me that in your like 10 years of making content for space, seems that space is really getting active. Like when I started following your channel there were really only a handful of science missions going at a time, the usual players in space launches, and not really any commercial launches outside of gps, communications, and global observatory
    9
  63.  @tonywells6990  it doesn't even boost the economy, SLS's core technologies are ancient. yes the new composite manufacturing techniques have uses but then the industry for giant composite tanks isn't entirely that large either. its not like sls is pushing new technologies that will lead to any radical breakthroughs, its all tried and tested (and expensive) legacy hardware, exactly like the senator from alabama intended these engines for example will be horrendously expensive to remanufacture when they toss away the entire lot of shuttle engines nasa had left
    9
  64. its more of a tech development project. I think it will fly and nasa will use it to loft another space station, but the current plan on it is terrible
    9
  65. MegaRazorback you put it in a small box in a cool place and it still explodes
    9
  66. I think its better to just adjust its orbit so you're nearly 100% certain its going to hit the South Pacific Ocean(ic) Uninhabited Area
    9
  67. Yanick Zeder mars has an atmosphere though. the rover had radiators to radiate heat in a vacuum while mars does have enough atmosphere for it to freeze things pretty easily. our space probes have a hard time staying warm instead of overheating
    9
  68. "How do we make camera survive in space?" "Put it into atmosphere?"
    9
  69. ya I used to microscope composite bearings, when we saw any voids it was trashed, regardless of how expensive the part was
    8
  70. "Here be dragons" indeed, the edges of the map would be absolute certain death
    8
  71. always ceases to amaze me we can launch a thing to the other side of the inner solar system and return to earth on target, and still can't get parachutes right
    8
  72.  @weldonwin  also they used the space shuttle's cargo bay as a passenger compartment, and somehow we launched like a hundred shuttles at once. Moonraker is crazy
    7
  73. both SpaceX and Boeing are using the same docking mechanism so not really.
    7
  74. L4 and L5 are essentially the bow wave and the wake of the earth/moon's gravity balancing out, they form a equilateral triangle with the earth, moon, and position
    7
  75. it'll be interesting to see what they come up with. I've worked with polyimide composites which are supposed to be about the limit of what you can do with polymers, it was pretty resilient stuff but I wouldn't put it next to a burning methox torch like you get from the engine, it will burn up eventually
    7
  76. Tom Chan or you know... they could just bring nukes with them
    7
  77.  @WolfePaws  ya but having read those apollo-x proposals with hindsight its pretty certain the crews couldn't have survived in space for something like a year given the limited experience we had with exercise and other life lessons
    7
  78. just don't get 20kg of scrap
    6
  79. seen weirder guys as DJs
    6
  80. early soviet spacecraft are fascinating with the way everything was analogue and yet they managed to accomplish quite a lot in orbit
    6
  81.  @t65bx25  they had that waterworld episode
    6
  82. it is kind of ironic that given the initial need to avoid a weaponized rocket they went with increasingly larger solid rockets, then by the time you get to the Mu series, most weaponized ballistic missiles were large solid rockets, and the M-V outwardly looking identical to many large ballistic missiles today, but all this was kind of by accident as IRBMs and ICBMs in the 50s, 60s and 70s were liquid fueled beasts until you got large amounts of things like minuteman, peacekeeper and topols
    6
  83. Man I hope congress gets around to allowing NASA to repurpose that keyhole spy satellite the NSA gave to them a few years back
    6
  84.  @underthelidar  the idea is 1) obtaining elements is not a problem, if we wanted to build a gold shielded ship, we really could, cobalt is stupidly expensive and we make airplanes out of it. I've held a bag of rivets that was worth more than my car, and seen people casually toss out palladium because its listed as an expired reagent. (both times it hurt inside) 2) you can use less mass for the same shielding since its almost twice as dense, so you're saving fuel which is the biggest cost constraint on any long duration mission.
    6
  85. As every kerbal player knows its always the last few kilometers that gets you
    6
  86. well, she is liable to go off spontaneously if not properly cared for.
    6
  87. aerospikes and other compensating engines do this by using the airflow to compress the gas as if it were the outer wall of the bell as for why nozzles don't expand/contract like fighter jets it's because they have to run fuel through them to cool the bell to keep it from melting. rocket exhaust is much hotter than jet exhaust so pretty much no metal exists that can survive it well enough, so they need to actively cool it
    5
  88. kerbals haven't invented daka yet, or they gave up daka after the kerbin unification war as the fannon would have it
    5
  89. huh, there were a bunch of scientists that have said we probably learned more about building a bomb in the 20 years after we stopped testing bombs because of the switch to computers. its one of those very tricky problems
    5
  90. Timothy McLean the antaries worked fine, they only switched away from the nk33 to get a boost in launch capacity and safety track record
    5
  91.  @stevenf1678  ula was formed because boeing caught lockheed stealing their secrets and lockheed caught boeing stealing their secrets so they formed a joint venture to save both the embarrassment of admitting they were both undertaking campaigns of corporate espionage
    5
  92. it'd be cool if they took the lessons learned from this and service hubble before it crashes sometime in the next decade
    5
  93. I wonder what we could do with 2-3 hubbles orbiting around at the same time in a cluster, cmon DoD where's another keyhole satellite so we can put up a hubble cluster
    5
  94. HI PHIL SWIFT HERE, TO SHOW YOU THE POWER OF FLEX TAPE, I CUT THIS ROCKET ENGINE IN HALF!
    5
  95. ​ @reddragonflyxx657 the first successful cables were single piece, laid from england to the US without breaking, and they broke down after a while. successful transatlantic cables took a bit longer as the splicing, material technology, and transmission equipment improved quite a bit after the 1880s
    5
  96. 15:50 if I remember correctly in the book they were using the roci's rail gun which itself needed the ships main thrusters to normally counteract its recoil and firing it normally to their orbit to shift it and buy time not to keep them in orbit indefinitely never seen how the show did that scene though
    5
  97. reentry heating was a serious plot point of one episode of the original show
    5
  98.  @noeoep  Going out on a limb but I'm guessing the life on the star is made of neutronium, or w/e ultra dense matter they called it, and arose under an evolutionary process just using intensely dense matter and massive heat
    5
  99. Alessio Andreoli koralev was replaced by an incompetent alcoholic, at least he got his stuff together later on when they were doing space stations but he was not ready for the hot seat so quickly after koralev
    5
  100.  @TheShowdown16  gps was planned production. these are global sized networks with trash that could be around for tens of thousands of years, it'd be irresponsible to not put some people in the process who aren't being paid to launch these things
    5
  101. killed because someone screwed up the tuning parameters just like my senior year modeling project, though that was just water valves
    5
  102. certainly gonna keep your house warm
    5
  103. Being Elbonia they've clearly purchased the VA capsule and license from the USSR and or Russia, as it is a futuristic reusable space capsule that may or may not have been a potential deathtrap. As for booster they went and purchased a Long March 1 from china to mate to their capsule, also they're investigating tri-fuel rockets
    5
  104. funny, I was thinking Moonraker and its ridiculous marines-in-space delivering shuttles
    5
  105. he could be playing the Kirk angle "we come in peace but I see you don't share our exact philosophy so we are now gonna totally overthrow your way of life, but hey freedom!"
    4
  106. +Павел Жданов the rocket they were going to use was already using mass produced engines though, they just "taped" four of them together, so they weren't expensive like the shuttle engines. in fact the exact same engines from the energia program are (or were) being used on a ton of American launches. the Soviets really were thinking right when it came to engine development, where as in the US we just sort of built one engine over and over again, today however renewed interest has at least kick started US engine programs and we seem to be following what worked for the USSR, economies of scale, and simplicitt

  107. The Mashroomia Tube to be fair, the workers on the r2 missile often snuck off with some of the propellant after work...

  108. TheLoganatorz they look like they took a lot of inspiration from modders already
    4
  109. There are satellites that are more robust by the nature of their duty so these guys have to be very limited in what payloads they take
    4
  110. this is genuinely one of the few things everyone can be proud of humanity for

  111.  Wallace  Hold your guns. Yes Von Buran was involved in using slave labor and didn't seem bothered by it but he can't be held accountable for Hitler shooting his rockets at London and elsewhere. He's a complicated figure for sure but he was also working within an evil society which used slave labor and his superiors had standing orders to shoot him if he didn't cooperate.

  112. apollo used a kapton mylar layer over the outside that turned silver when exposed to vacuum, but turned yellow when it ablated its quite interesting

  114. Loebane yes but they had to land on the moon to make it more real

  115. CHEEESE
    4
  116.  @Thefreakyfreek  the insane part is how easy it is to build too, get past the launch issue and ya you have something equivalent to a nuclear bomb without the radioactive fallout and really the launch issue is just one of cost which as we have seen in our nuclear program is not exactly an issue

  120. NASA having a shortage of parking spots on ISS is a great thing given how things have gone since shuttle

  121. in 2 years when they're landing on the moon they can just launch another one when the astronauts can't get out the door

  122. this friend of my dad's has a 1957 Cesna, there's probably something to be said about glass cockpits compared to how basic things used to be. Id be scared to get in that thing with him

  127.  @jemborg  not sure where you're getting the part about their planes being unflyable. they were really difficult to fly but they did work, the replica built 10 years ago for the 100th anniversary was built to wright specs using both drawings and surviving articles and was flown. Its just the wrights in general were not so great at business
    4
  128.  @ryanevans5211  doesn't antimatter have normal mass and gravity though, just that its charges are all opposite to normal matter? I thought the exotic matter in the warp drive was just a hypothetical type of matter that solves the equation, not that its something that could actually exist
    4
  129. and everybody on one side of the isle still bemoans obama for 'killing' shuttle and not giving out enough poorly negotiated contracts. A lunar landing by 2024 is absolutely nuts, we would need to have an operational LEM, CM+SM+booster by next year the shuttle's components are like the zombies of rocket science, they just can't die and make room for non compromised rockets
    4
  130. does say something about japan's industry in the 70s that they could just pick up a US rocket design and pretty much build it without any major redesigns. idk if britain could have done something similar at the time

  131. wonder how they're going to make the batteries reusable since I was always under the assumption that electron was pushing the batteries to the limit, accepting what could be long term damage since the thing just blows up in 10 minutes anyways

  132. "You don't want 100 questions in a single video? do you??" Drachinifel does several hour long Q&A's every week, I don't know how he has the time but its a meme on his channel that a 2 hour AMA is light on content. Mind you, he's researching most of the questions too.

  143.  @Markle2k  there's multiple heavy launchers that will be better in almost all regards than sls, you have new glen, a variant of the vulcan, the arine rockets, falcon heavy and bfr, sls is just bad engineering, the first stage engines alone are a boondoggle by using the most expensive engines ever developed and throwing them away every time, the ssme's were not meant to be burned up

  145. SPACs seem like the new power play to keep the public from buying stock by selling all the stock years before you even have the company, but hey the stonk market isn't rigged by a million gimmicks that only the in crowd can navagate, to claim otherwise means you're a potato farming communist
    3
  146. As much of a threat it is, I also wonder if the top brass in russia have discussed how much of their remaining technical knowledge they will have to turn over to china if they go into business with china. They already got burned by china reverse engineering the soyuz vehicle back in the early 00's
    3
  147. ​ @LoociferZ they're dealing with potential hull failure.
    3
  148.  @brontehauptmann4217  uh what? if you built models then you should have looked up pictures of the LEMs with the rover unfolding, it was basically a flatpack thing that they pulled out on a cable. Also for manned missions especially earlier in space exploration the vehicles had extra deltaV for unanticipated maneuvers and correction burns since the guidance systems were pretty rudimentary and actual trajectories had to be calculated on the ground using larger computers. But the biggest flaw with moon conspiracies is that there wasn't a way to spoof live broadcasts from the moon back in 1969, the soviets could pick up the apollo telemetry, as could anyone with a dish of sufficient size. Nasa didn't have an orbiting satellite network until later in apollo, and again, the soviets would have been able to determine if nasa was on the moon or just in orbit

  149. US custom is for buildings to have the 1st floor be the ground floor, same with rockets.

  163. maybe but china has launched less manned missions than NASA before Apollo with a single mission each year for the next 5 years
    3
  164. not quite that. The 3 landers all represent 3 different types of strategy on NASA's part and 3 different levels of technical development needed

  165. He's just mad he got written off in season 3

  166. God has a sense of humor. We had to put glasses on a telescope before we could see the immense beauty of the universe.

  167.  @Amerikanskis  they used a lot of their titanium fabricating submarine pressure hulls. Like I'd imagine 1 typhoon was worth 4 sr71's in titanium

  168. ballz deep69 cmon, even Elon can't do the impossible.

  169. that 2024 "mandate" was going to deliver 5 frozen corpses to the surface of the moon because thats how rushed it would be
    3
  170.  @nathanlee6654  the trunk is basically an interstage adapter with solar panels but space-x doesn't seem to want to utilize it for anything but empty space or transporting cargo
    3
  171. ​ @volvo09 shedding the heat is the biggest problem
    3
  172. its always puzzling to me how many mental gymnastics american companies will do to avoid developing new engines. Like Spacex has problems, but at least they developed their own engines and have the skills to keep doing so. The engines are the entire rocket, everything else comes from your engine performance
    3
  173. Getting it back to earth orbit might be easy enough as using that satellite recovery bus vehicle the DoD has been messing about with, just grapple the ascent engine and use that since its around the CoM, or use the docking node since its still there. getting it back down is maybe harder requiring something to encapsulate it, deploy a heat shield and land it, and its gotta land on the ground too since its gonna have to land on land
    3
  174. the aerospace industry is a confusing bunch of consolidated units
    3
  175. paying near 200$ for nowhere near a gigabit because I'm 1 block away from competition so we're a captive customer
    3
  176. There were probably some nasa engineers turning blue until the engine valves and solar panel opened
    3
  177. solar pickles, bacon heat exchangers, lettuce thermal control blanker, burger heat shield my god its better than MOOSE!
    2
  178. the game devs must have been huge TOS fans, evil gas aliens, the Horta, antimatter torpedoes...
    2
  179. oh nixie tubes, ya those fragile, hot, high voltage tubes are exactly what you want in a spacecraft. looks cool though
    2
  180. legacy space was having a senior moment in the early 90s, Boeing/Lockheed were caught spying on each other, you had the intelsat get stuck in LEO thanks to a titan III failing, the new roscosmos trying to figure out how to space, ESA having the above mentioned failures.
    2
  181. Not only that but this also puts him as one of the last solo spaceflights a feat that probably won't be repeated without exceptional need
    2
  182. ​ @benjaminhanke79 Piketon, Ohio did some of that work too
    2
  183. ya but doesn't that result in a shooting war on the moon's surface...
    2
  184. RIP Voyager I and II sometime in the 2020s, the math on the RTGs just sadly shows they're gonna run out of power sooner rather than later
    2
  185. nice to see all this innovation in rocketry finally.
    2
  186. gonna love to see a modern Mir-type station get built. I think the ISS certainly is good but it had to be assembled by the STS
    2
  187.  @tlamn1905  the nevada proving ground was so blasted that they used it as a moon analogue for astronaut training. Strontium from the tests contaminated the entire world. All metal products refined today are still contaminated with nuclear byproducts from the atomic testing of the 50s, both from the US and USSR. Nuclear weapons testing is incredibly destructive and permanently renders the land unusable. There just isn't any reason to continue it today with all the simulation power we have, and people who think its useful for geopolitical posturing need to take a course on the cuban missile crisis since nuclear testing between the US and USSR absolutely propagated that crisis
    2
  188. Just Being Socially Awkward We had a 2 stage to orbit rocket with a fantastic spacecraft in Saturn IB, they could have redesigned the CSM or build a new vehicle but shuttle was something nixon signed off to keep nasa busy for a few years scratching their heads instead of asking for more money
    2
  189. really getting concerned since you have at least 4 companies making these huge constellations, then both china and russia wanting to build them, and a few other countries indicating they want in, and we already were having problems after we did this with GPS and now you're talking about 1000x the stuff in orbit compared to gps
    2
  190. The japanese mission probably took up the space and mass that any lander would have needed. The question would have been whether an orbiter or a lander would develop better science and the orbiter obviously would be better at this point.
    2
  191. on the up side, it has amazing coverage over Antarctica
    2
  192. kind of sad the rear pusher engine design proposal didn't go forward, its the more interesting of the two
    2
  193. Not sure how well cryogenic fuels will store in space, nobody's really tried yet, I guess spacex has an answer but I'm not convinced on other rockets you could store hydrogen indefinitely
    2
  194. the end docked to the reentry vehicle does not have an airlock
    2
  195. eh, ditching all that already paid for apollo hardware for some pie in the sky space shuttle that would take 20 years to build anyways and could be massively underfunded was a bit more of a embarrassing story
    2
  196. the one thing is that nuclear fuel would make sense to ship over the vast distances of space, its very energy dense, very compact, and from a commercial prospective it might actually be something that could be profited from, assuming it can be shipped intact
    2
  197. they want nasa to stop doing "woke science" so they're gonna starve everything but manned space of funding.
    2
  198.  @ryanhamstra49  not sure the ground equipment and range safety equipment can handle 2 rockets simultaneously. nasa only has so much cryogenic fuel storage capacity, and only so much equipment. My guess is its not trivial to retask the ground equipment for another launch, though they can do it somewhat rapidly
    2
  199. I feel like they ought to be able to model the issue with the blade but then the rover would have to wait on it to get back to speed
    2
  200. these guys were only up there a few minutes at a time though, far far less than what we're doing on ISS or did with Apollo
    2
  201. its funny how shuttle was somehow both too radical for the tech of the era, and too conservative for the tech of the era
    2
  202. I wonder though if they do more pure research since ESA grew out of all these national laboratories and programs
    2
  203. The dome also doubles as bathroom, its great, also absolutely terrifying if you think about it I'm not sure how they're able to send these people up without an astronaut onboard
    2
  204. anything nuclear would probably not be great for your hand lol
    2
  205. When drinking soda. Stage 1) open bottle Stage 2) panic!!!
    2
  206. too much displaced volume, the issue is every baffle or sponge you put in your tank replaces what would normally be fuel, so you want as little mass and volume of material as possible for the job
    2
  207. I think those were only active during the launch, and never useful afterwards since if your chute is tangled on re-entry you're probably tumbling and rolling around
    2
  208. not that impressive since we've been able to get from Montana to Moscow in 30 minutes or less since the 60s though that's always been purely on paper
    2
  209.  @eekee6034  go read some of the speeds they used to run passenger rail back in the 1920s, they were possibly hitting speeds of 140 mph on sections of track but nobody bothered putting speedometers on trains back then anyways so the record for fastest steam engine probably isn't the actual record
    2
  210. maxwell the guy that basically worked on everything and had a hand in everything
    2
  211. just dayton, where they have the ability to store it inside
    2
  212. Ah I had not realized this came that close to impacting the ground at high speeds. looked like a textbook landing
    2
  213. probably had no way of getting to them, the parachute ropes were under water as was probably the mounts
    2
  214. Ok NASA may be writing up a plan for an alien discovery, or they want to set up a hell of a joke involving a priest, a rabi, a padre and an imam walking into a room...
    2
  215. man you're targeting the single largest stretch of barren flat land on earth, and you hit the one inland sea
    2
  216. a rocket is 10,000 ways to be wrong and very few ways to be right
    2
  217. kind of shocked the ministry of tractor development didn't get the com sat program
    2
  218. I remember reading an article at my last job when we got these aerospace journals, there was a company claiming they could avoid the bit flip problem by using just many more error correcting elements by using newer, but not radiation hardened equipment since they'd get a big processing, speed, and power boost while being able to package like 5x the hardware in the same space. Basically trying to correct the errors faster than they occur
    2
  219.  @Krasnoo  bruh, we're on metric, we just don't tell anyone.
    2
  220. The sprint missile went 0 to 3403 m/s in 5 seconds, i think that takes the cake
    2
  221. "Hallo, I'm standing in the middle of a residential neighborhood, but you'd never know it!"
    2
  222. At some point someone had to have uttered the phrase "Bite my shiny metal ass" during the coarse of the training for that mission
    2
  223. always wondered about this problem, even though I worked around a giant steam powered vacuum chamber I never thought about using the engine exhaust or steam injectors to suck the gasses out
    2
  224. scott, a hyperloop on the moon is just a railroad.
    2
  225. It was Karl's fault, he forgot to put it on charge last night.
    2
  226.  @shaniamonde7341  starship will almost certainly require a prepared landing surface on the moon, not strictly a problem if artemis ends up landing several other landers but people have to be realistic about space-X's big rocket
    2
  227. The megabus went bankrupt though
    2
  228. there's gotta be a joke about a chinese made Mir copy, hope they planned it out better than the USSR did
    2
  229. its also a great example of applying the latest sciences to find new discoveries, from photographic plates, radio waves, electronic controls. whenever we've invented a new technology we've found a way to improve or create brand new telescopes
    2
  230.  @MrHuram-abi  eh its not like nuclear regulations sprung out of nothing, its that most of our nuclear technology was a side quest, a byproduct of nuclear weapons production. there's some truely horrible piles of nuclear waste left over from the bomb program
    2
  231. Everyone who laments the loss of shuttle knows nothing of all the near misses we had with it
    2
  232. wonder if its one of the 2 x15s left, I've visited both
    2
  233. It did come to me the other day reading an article about this launch just how wildly optimistic people were (and maybe cynically so) that taking parts from shuttle would just work tossing them into a completely different vehicle. There's almost no pieces on this that weren't re-engineered or built from scratch for this rocket. this wasn't 'bash a rocket together from spares' this was a brand new rocket with some off the shelf hardware and because its disposable the rs-25 engines which are all relics in their own right, are all gonna be trashed
    2
  234. interesting they still managed to come down on the legs, hope they beef them up for the next one, seems like nasa was very very concerned about that on the apollo missions and rightly so
    2
  235. the canadarm is actually a canadaworm
    2
  236. seems like if we tried it would fall apart being a dustball
    2
  237. something beyond apocolyptic would have to happen for the last one to happen since the last time that place was under water was when there was before the last ice age
    2
  238. quite interesting thing they seem to do with assembling the rocket on the pad
    2
  239. ya except these satellites are in low enough of an orbit that they'll burn up after their useful life unlike irridium which is stuck in the geostationary graveyard
    2
  240. I liked the things they had in the USAF museum, one was like a go-cart with gas jets, and another was a more primitive version of the gemini 8 wand
    2
  241. Zoom, enhance, Zoom, enhance!
    2
  242. Dihydrogen Monoxide propellant is an excellent storeable propellant
    2
  243. this wasn't really an in flight failure in the same way that like Orbital ATK's failure. had this been on a pad it would have been an abort
    2
  244. great quote but there are people who do get killed by ejector seats from time to time which is speed
    2
  245. US Launch: Nice sunny florida day USSR Launch: Flipping blizzard
    2
  246. as much as I dislike the guy, spacex the company never shies away from heavy equipment and seems to pay off, though they might be putting too many eggs in one basket if their launch tower also stacks their rockets and also catches their rocket and also has a not insignificant chance of getting blown up and has a lot of very expensive components in it on raptor, I absolutely never understand why space-x is the only company that really understands the engine makes the rocket
    2
  247. Maybe crossfeed is nearly impossible but I wonder if you could bleed some oxygen off to the center booster as most boosters run fuel rich anyways
    2
  248. Matrim Helmsgaard no, just an impulse of thrust while in that orbit
    2
  249. a whole carbon fiber booster the size he's talking about would be massively difficult to construct compared to welded metal.
    2
  250. 9:34 if this doesn't scream "Nuclear Umbrella" idk what else would, a US flag above a row of foreign flags in front of a US orbital capable rocket
    2
  251. you should tell the story of how mouthwash and nazi rocketry are connected

  252. scott, can you turn off the wobbly camera? it makes things too wobbly!
    1
  253. kellicams should be the unit of distance

  254. any word on when that telephone switchboard game is going to be released?

  255. this modpack looks really fun/grindy to play
    1
  256. This is exactly the plot of a Stargate Atlantis episode I wonder if they took notes...
    1
  257. Scott redesign your ships and enact planet wide edicts to boost power on your energy worlds

  259. its alien pigeons scott, they crap superacid
    1
  260. the most OP of OP weapons in sci-fi. I don't really get how a beam that's good at disrupting matter is somehow better against shields though
    1
  261. really amazing video
    1
  262. Scott, you sent the probie to abduct him
    1
  263. scott you forgot to use your head, to stear
    1
  264. well maybe a moon landing would have been possible in the 1950s if we had spent more time building the missile instead of the bombs that went on them, but then again there were certain technologies that just took 15 years of trial and error till they were ready to be used for manned spaceflight
    1
  265. I love that ship, I think I remember seeing this things website years ago when they were developing it long before elite or starcitizen
    1
  266. that massive srb required a minuteman missile 1st stage to ignite which is just as crazy
    1
  267. you should do a video or live stream where you freeze the earth like this and try various geoengineering solutions such as slamming things into it, decreasing albido, or massively ramping up greenhouse gas levels
    1
  268. you forgot salyut 3 which had its own stabilized 23mm autocannon for "research" possibly on the effects of 23mm cannon fire on gemini spacecraft. not only was it fired a few times by the crews, after the last of them departed it was remotely fired until depletion and it actually moved the station's orbit
    1
  269. Scott, it was a cold fusion bomb, as in a fusion bomb that freezes things because it's cold....
    1
  270. TheSeppentoni yes but it (and the soyuz capsule) have killed the most people
    1
  271. epic space battle coming soon
    1
  272. reusing ssme's that haven't been in production for 30 years and are insanely complicated to build and use for a big dumb rocket is truely a waste of money and resources, we'd have better spent it on a modern f-1 (designed with modern cad and cfd) that could be greatly simplified and the production line would be cheaper than restarting the ssme's line
    1
  273. the music is a little overdramatic "we could make some med kits" BWAAAAAA DUUUN DUN DUUUUN maybe bring the volume down a little?
    1
  274. Scott just make sure to have all radiation flushing hatches closed and all air vents turned off when fighting giant outer space cloud aliens that or have a Vulcan on hand to give it a bad taste before nuking it
    1
  275. presumably the most effective means would be launch some kind of orbiter followed by a stream of impactor vehicles, I mean if we had 7-8 years advance, we could launch a dozen interceptors that would be corrected for each successive impact that would move the asteroids trajectory space-x alone can launch ~7-8 rockets a year, if we knew in advance we would just build a whole bunch of vehicles to launch to it
    1
  276. it seems like they need to add ships that are dedicated freight/explorers with larger frameshift drives
    1
  277. fly safe!

  278. verner von kerbal found that inert plastic explosives make the perfect heat shields, unfortunately they tend to become shock sensative when impacting the ground...

    1
  280. commander. I think the avatar project needs to be taken care of...
    1
  281. no you sir fly safe, have a nice vacation scott
    1
  282. watching this you do see the sad gap in rocket engine development from the 1970s onwards, there should have been no excuses for not having an american engine for the atlas V, instead we built the whole thing around an engine we cannot control the source, which would be a huge problem in every other part of the aerospace industry
    1
  283. Scott, if you are ever in southern Ohio, the Dayton air force museum is the most amazing collection of planes, nukes, missiles, rockets and anything else that flies or tried to fly
    1
  284. scott, i think you proposed the best proof against this, just build a wheel with these things and have them spin around and generate power, if they break even or come up with more power then we give up and enjoy unlimited free power if it doesnt then its dead for good
    1
  285. I love how bad Scott is at being security, but he is pretty good at being on fire
    1
  286. heysus is like the redshirt of Scott's team, like every mission he gets shot first
    1
  287. +Scott Manley please do finish it, you do such a great job at it
    1
  288. many redshirts were lost this day.... eh but we can always get more redshirts.

  289. scott, you could have used some tape when painting, some scott...tape...

  290. Worlds most accurate toast simulation!* * nobody else has made toast physics simulations
    1
  291. 1 point though, as a weapon against forts the idea was this mass of burning exploding powder might land on or near a powder keg or even better, a powder store and blow up something. this didn't work out here since we had the time and knowhow to build good forts but some native population with wooden fortifications and inadequate fire protection for their powder, these could be a very very bad thing
    1
  292. Scott your research is fine, build powerplants already

  293. war...war never changes

  294. operation banished squirel!

  295. eh I think xenonauts was way more tactical, here you suddenly get super kill guy, in xenonauts you had a very tough final mission where you had to advance just right
    1
  296. Scott, get out and push
    1
  297. clearly the ship is using kilogarns as the units of distance
    1
  298. this game contains far too many TOS and star wars references
    1
  299. I'd imagine it's less invisible but too fast for stations to see, like the plane is on the scope for all of a couple seconds modern digital and passive radars probably have less of a problem with this though
    1
  300. Scott would this ship be classified as a boulder holder then?
    1
  301. automatic bee guns aren't as cool as they sound... I mean Gordon Freeman certainly didn't care for it

  302. distance traveled: FOUL!

  303. Scott you make this seem so easy, even after playing ksp enough to land in my sleep this game is difficult

  304. so evil, throwing his daughter in a shredder. at least she got him back at the feris wheel
    1
  305. molusks have a tongue and mouth filled with thousands of horrifically sharp teeth
    1
  306. I wonder what engineering hurdles a horizontally launched rocket poses verses a vertical launched one
    1
  307. beppi-columbo just sounds like columbo's italian cousin
    1
  308. as much as I'd like to see it saved somehow, the space station's hull seems to be failing in ways we don't exactly understand. If we had shuttle I'd say try to haul one of the core modules back but idk if it could have even done that
    1
  309. hopefully didymus won't take offense at NASA pushing Diddymoon around
    1
  310. weird how we keep developing this tech over and over again. multi stage guns have been a proposed thing since like the 1920s
    1
  311. ya they weren't sure how solid the moon was when they started building it which is wild by today's standards
    1
  312. those two cans are pretty neat, seen them in a museum. cokes was pretty overengineered, it was a bag pushed out by a nitrogen cartridge.
    1
  313. Why are these horizontal launchers so hard to get right, we launch missiles horizontally all the time on higher g-loads, we launch small rockets fairly routinely now as well and we have ample modeling on dropping stuff off of planes
    1
  314. they ought to have stuck with Saturn 1B, it was basically a cheap whacked together rocket to begin with, the apollo csm could have been redesigned in the 70s to implement solar panels and build basically a LEO variant for servicing skylab or some future space station, and if we wanted to go back to the moon, we had the infrastructure
    1
  315. But I thought Big Rock lost the 2020 election...?
    1
  316. Cool, they can quickly translate this to the Commercial reactor program that was running parallel to this, oh wait the Tea Party defunded that back in 2013
    1
  317. ya sure the airstairs are for regional airports, not say supporting clandestine activity in laos or south america and certainly not for paradropping supplies while pretending to be a totally legitimate airliner that just so happens to be owned by the cia
    1
  318. now we really can fly safe
    1
  319. I prefer the Metric Calendar, have 5 extra days at the end of the year dedicated to time off, sounds absolutely fantastic and better than 1 day off for labor each year
    1
  320. its almost like 2024 is an arbitrary deadline set as a setpiece to a potential political campaign instead of a realistic timetable
    1
  321.  @fredsas12  the US and Britain were working on jet engines we just didn't put the resources into them to mature them in time, instead we focused on mastering the current technology of piston and massive radial engines which was a good thing in hindsight as jet engines required a lot of advanced work that took another decade to really start to out perform piston engines.
    1
  322. maybe its because I work on batteries all day but the new electron looks like a giant AA battery
    1
  323. is there any reason why they couldn't just build a pad for landing...like a landing pad?
    1
  324. sending a manned dragon around the moon before NASA sends an unmanned Orion capsule around the moon would probably be worth it if only to get the most hawkish congresscritter to finally kill SLS

  327.  @a..d5518  na, that was redstone the competitor to atlas
    1
  328. seems odd they're landing ahead of a hurricane like they are.
    1
  329. the xb-70 ripped the entire cockpit off when it ejected, that'd be how you'd do it with a mach 10 vehicle, there were problems with the aero shells injuring people if I remember correctly, which along with weight are their biggest faults
    1
  330. I think Asparagus staging is physically impossible as there's no way to really crossfeed without cavitation I think
    1
  331. ya the very little development work done on the actual super heavy is what I'm not convinced about. we're talking about something on a new scale entirely and they don't want to talk about it, assuming its gonna just work, something the last guys to build rockets that big learned the hard way post vehicle processing is never going to be as quick as they want because human safety will draw things out, you just can't inspect a vehicle in a day and call it safe
    1
  332. its kinda one of application. We didn't need something like it for shuttle and the ISS, (though arguably it would have been useful) But nobody could ever justify building something so big until now
    1
  333. rocket fall over mr. bond. rocket fall over.
    1
  334. huh, grabbing the old engine was my first guess but using the new vehicle as a single satellite is a novel idea, though someday one would hope there'd be a way to connect future satellites also this does bode well for clearing up some of that geostationary orbit because you could slowly drag satellites down to earth using a cheaper more disposable version of this
    1
  335. blue origin buying starliner would be funny as hell and also absolutely a way to leap into the commercial crew without having to pay for most of the work since they'd just have to fix it by now
    1
  336. So where do the people and or cargo go on this thing, right now its literally the world's largest model rocket since it has nothing but tanks
    1
  337. when the booster and capsule have a difference of opinion and leave

  341. At some point somebody at ULA had to have noticed it was going to catch on fire and decided "na just let it burn" then managed to convince everybody else that it was for the best.

  342.  @pseudotasuki  delta IV always looked like someone had the bright idea to take a shuttle tank and turn it into a rocket

  343. I wonder if a solid tungston ball would survive since its melting point is ridiculously high compared even to stainless steel
    1
  344. w8 they weren't even going to recover the srbs? man that sucks
    1
  345. funny, they basically gave up on what they started for, but ya sticking with electric driven engines were not going to scale up
    1
  346. same with the apollo CSM, the spacecraft in pictures are that beautiful shining silver in space. they had many layers of aluminized kapton that kept the temperature regulated and were protected by a nosecone on the saturn V but would also burn off once the vehicle reentered the atmosphere
    1
  347. scott, casinos already use magnetic balls to rig their tables plus centrifugal forces arrising from a ball on a heavy spinning wheel

  348. "This game simulates everything, atmosphere, electricity, data, heat." "So i put the coal into the space generator and made power in space."

  349. Davey crocket: the nuclear punt gun
    1
  350. an interesting problem with opening the doors on the ground since the back of the shuttle would be venting toxic chemicals on landing, so opening the suit wouldn't be a good idea initially, the dude would have to sit there probably until the guys in hazmat suits cleared the maneuvering fuel
    1
  351. To quote some other british guy, "Location, Location, Location." Scott, could you ever do a video discussing how to get refined space matter back to earth without killing us all? I've never found any solid plans but you're 100x the obscure space plan researcher than I
    1
  352.  @Chris1911-f4k  boeing was behind space x by a few years and had some of its own design troubles early on
    1
  353. @rpbsjy I think given all the cash to put them into service both will be kept as they both will have their own merits. Starliner looks like it could be more readily adapted for deep space flight while dragon 2 would need a different service module
    1
  354. And I'm sure in NASA tradition, congress won't fund the improved SLS booster, not that it matters since SLS is insane
    1
  355. how do you even do rotating space stations with giant solar panel wings?
    1
  356. if you said 10 years ago Sierra Space would reach space about the same time as boeing you'd have been laughed at
    1
  357. Excalibur Almaz, haven't heard that in a while, too bad that thing kinda turned into a money laundering scam
    1
  358. ​ @sunspot42 certainly breaking rockets as fast as they can launch them is probably a bad strategy if there is some problem you can't solve but the N1's problem was down to QC and control systems which we just are so far beyond that they don't really have the same problem
    1
  359. Coal Powered Rocket? The GOP will demand we close this technology gap immediately
    1
  360. Mythbusters' Steam Impulse rockets were quite intriguing and promising, though the complete lack of control and severe lack of payload greatly limited any commercial prospects.
    1
  361. you should get out to wright-patterson afb in dayton and see their rocket farm someday
    1
  362. its actually a funny cobble together shuttle booster if you look at that.
    1
  363. what they've basically built is a Titan III by their own development path
    1
  364. Sounds great but there's like no place you could ever test this at anything but in space far away from the planet
    1
  365.  @hououinkyouma1458  I think the sun shield only opens after it reaches L1
    1
  366. Ted Archer pretty controllable honestly.
    1
  367. Ted Archer it does bring to mind an idea to use radioactive tritium instead of normal hydrogen for a liquid rocket fuel
    1
  368. Starship doesn't seem to be ready to commercialize while New Glen is a commercial rocket BE went big first and I hope it pays off
    1
  369. gee I wonder what happened in the years between 1978 and 1990 that kept the US from approving any new probes. Like I know its beating a dead horse but Reagan was such a shit president when you dig even 1 mm under the coating of nostalgia, Star Warz was a massive waste of cash that would have resulted in putting more nukes in space just to use them to prevent the soviets from using space to nuke the US, which in turn would have forced the soviets to put their own nukes in space to stop our nukes, ect ect
    1
  370. I've seen one of the few Loones left, they have one or two kicking around in the Wright Pat museum towards the end of the ww2 gallery, I think almost all of them were destroyed.
    1
  371. really wish more from almaz was declassified, spy station or not, they were historical steps
    1
  372. episode 2-45: forgot to check your code
    1
  373. boeing's issues wouldn't necessarily have been an issue if there was a crew, at least one of them
    1
  374.  @PetraKann  at the time designing high efficiency nuclear bombs was the bleeding edge of physics, let alone nuclear physics
    1
  375. saturn 1B should have stayed in production
    1
  376. I like how we've reached the silly end of what venture capitalists will fund
    1
  377. neither GE or Pratt want to go through the process of getting an open fan engine certified, though both have demonstrated the technology. I asked someone who was in the know some years ago
    1
  378. I think the problem with JWST fixing is its too delicate, though its possible the satellite extenders being developed now might be able to service it in the future if nasa really wanted
    1
  379. seems pretty obvious that you're going too fast to avoid frictional heating, and that there's not nearly enough atmosphere to use wings for lift
    1
  380.  @KevinBalch-dt8ot  orion's issue is manuvering it without any rear facing engines and managing the bomb magazine/catapult. in a 'straight' line its still probably more powerful than nswr
    1
  381. really a mission building on so many improvements. the juno spacecraft proved you can do solar, the falcon heavy proved it could lift a 6 ton spacecraft, new horizons proved some of the electronics, ect ect.
    1
  382. probably because there was absolutely nothing they could have done on STS to rescue the crew if there was a fire on the pad
    1
  383. They use Acme brand emergency equipment, the absolute premium* *warranty void when hunting roadrunners
    1
  384. theres an anime movie with this same effect (caused by out of control super science in its case) the civilization made up of people who floated away was really weird
    1
  385. to basically make it work you'd have to basically reengineer the entire vehicle to work for the moon
    1
  386. kinda hope somebody had the foresight to put a delta IV away in a museum but there's basically a finite amount of them left in the world and ULA has probably already built the last of them
    1
  387. One of the things that people fail to realize is just how flipping far away the moon is from earth, like it took astronauts several days of flying at thousands of miles an hour away from the earth just to get there, for the moon to crash into the earth it has to travel a long way to get back here
    1
  388. shoulda gone to cleveland we had paradoxically zero clouds
    1
  389. thought we knew which moon specifically not to go to
    1
  390. So nuke the asteroid while its moving towards a keyhole and send a bunch of crazy oil drillers to it on a 1 way trip?
    1
  391. a better question would be how survivable ejecting from the space shuttle on boost would be
    1
  392. hey scott, how does space-X intend to deal with the propellant boiloff on a multi month mission when shuttle couldn't have stayed in space for a few weeks without boiling off propellant
    1
  393. funny, the regulus II looks to have been much more successful than the Snark which was a total failure for the airforce
    1
  394.  @NorthernSeaWitch  ya and a modern airliner can takeoff, fly, and land itself but we still put pilots in there I guess at least 2 of them have extensive aviation experience
    1
  395. damn jupiter, being the bully of the early solar system (thx for clearing the inner sphere though!)
    1
  396. had to laugh when you were talking about things getting bad for the surface of the earth then an asteroid smashed down in the middle of north america
    1
  397.  @woodypigeon  well at that point you have most of africa destroyed, north america destroyed, and with that most of the world's food production and oil production destroyed, not only that but the continent wide fire is just not going to be good for anyone left alive
    1
  398. Doubtful, NASA's problem is they're being used as a political tool instead of just being left to do their thing. The 2024 moon landing is absolutely ridiculous, and is ONLY a PR stunt for the current president. Realistically giving them 10 years would be fine, but 4 years was silly
    1
  399. What did we learn: sadly, Nothing because everybody above the age of 50 waxes on about the space shuttle and whines about how Obama (not GW for some reason) killed the shuttle, and it was always shuttle not STS, not that they knew anything about the shuttle at all either. its really tragic but like challenger, the danger inherant in the design was something that the country couldn't ever really understand to a great enough degree to change public policy. Idk I'm a bit jaded because I grew up in the tea-party area and Shuttle was made into a culture war issue under the obama era, and now nobody really understands that not only was shuttle a dangerous vehicle it was built on a budget, and put up without any real mission, but kept getting flown because of congressional inertia and nationalistic nostalgia over the lessons learned from challenger. Columbia being incapable of supporting the space station mission, shouldn't have been flown anymore As always though a great video
    1
  400. mariner 2 just had a few too many drinks before launch, it was still OK to fly, you know how those mariners are when they're on shore leave
    1
  401. What's that you say? Prepackaged Mars rocks just sitting there? Quick Elon, to the Musk Rocket!"
    1
  402. should give a call to amazon, I'm sure bezos has a giant amazon delivery drone they could borrow to try and grab these things from the ocean
    1
  403. the scorpion is only a mystery in as much exactly how it sunk is unknown, why it sunk is pretty evident being the only sub in the navy at the time exempted from sub-safe inspections
    1
  404. think those were originally just marketing terms for specific grades of aluminum and stainless steel
    1
  405. I wanna see astra succeed because those guys are really pushing for the most minimal rocket possible
    1
  406. pretty crazy they get enough performance out of smaller one sided solar arrays, maybe someday they can replace the old ones completely to help reduce ISS's drag if they keep working on ISS
    1
  407. I know the pressure vessel simplified the camera but the scale difference between hexagon and zenit makes it look like a brownie camera by comparison
    1
  408. doubtful because they'd have given up on landing as they need the center engine to run the landing
    1
  409. orion, the ugly, radioactive stepchild of reaction rocketry
    1
  410. eh it probably gives you cancer but it probably won't melt your lungs
    1
  411. I feel like sending a capsule full of minor celebrities around the moon and back is so ridiculously dangerous. Like an LEO is much safer but also they're not so far away
    1
  412. Expandable Activity Module really sounds like a space bouncy-house
    1
  413. I never knew the jet engine was on a gimbal
    1
  414. seems like they ought to just buy siera nevada corp as they're seemingly in need of some help to get over the line, not sure what kind of technology restrictions come with that but the EU and USA are much closer than US and Russia (even under better times...)
    1
  415. I remember something pitched called Jupiter that would have relied more on several new core technologies such as another giant f1 style engine, methane upper stage, and such but i don't think it ever went past a white paper as for how delayed CC is because of underfunding is not really easy to quantify since spacex has done quite a lot of development outside of nasa launches. the thing is full funding could have allowed nasa to fund more than 2 vehicles, and possibly got ULA to test their stuff more thoroughly
    1
  416. my mazda was a rotating detonation engine but my mechanic said that was a bad thing
    1
  417. Does starship even make sense anymore? Like its supposed to have these massive internal tanks, a cargo bay, an internal habitable area, a crew deck, upper header tanks, massive amounts of life support, and have this massive endurance, all in one vehicle
    1
  418. Not going to say aliens, (but it could be aliens). but if it was aliens, how in the hell are we going to get a spacecraft into the right band of the atmosphere, nab a bit of potential life, and fly back
    1
  419. I really love all this innovation but at some point somebody has to realize that there's 50 small sat launch companies now and there's not enough payloads for them. I guess it all depends on the market, price competition, contract turnaround and good old government support, maybe they can support this many launchers
    1
  420. Honestly when you started this more than a few years ago, space was pretty boreing. now though...
    1
  421. there's the safe way and the YOLO way
    1
  422. Russia and China agree to work together, so basically china does all the work and russia gets to drink vodka on the moon in 20 years? Russia's space program hasn't exactly been moving in a forward upward trajectory for some time now.
    1
  423. I bet they're gonna have to test this vehicle at Plum-Brook because that's the only place you could shake the hell out of this in a vacuum
    1
  424. biggest problem with steam turbine ships was how long it took to get the titanic reduction gears to work and those massive gears were extremely difficult to make
    1
  425. NOR "Gotta Keep You Guessing!"
    1
  426. the saturn V launch computer was kinda fun, basically a mainframe sized computer stuffed into a building sized ring and given that computers in general sucked for guidance back then, it had better computing power
    1
  427. its hard for me to see how they'll ever fit a crew compartment into starship, let alone life support and power systems with all the propellant tanks around the thing, plus they then need to build a rocket that's like 3x the size of starship and get that to successfully launch and land reliably
    1
  428. the whole artemis program relies a lot on some hypothetical massive ramp up in SLS which certainly isn't happening in 2020 with coronavirus closing down the marshal space center
    1
  429. Norman M. airlines don't use 747s for commuter routes, neither would satellite launchers want to use such a large rocket for a comparatively small launch. Elon can talk a big game (and play one) but the economics of the situation as well as the aerospace industry certifications will dictate falcon 9h and 9 will probably be soaking up the satellite market for some time even after bfr
    1
  430. funny the people behind that gateway project know about artificial gravity, but they animated a bunch of people just walking off the shuttle in the near zero gravity center of the station
    1
  431. they used a fancy map
    1
  432. "Its like kerbal space program but with more communism and no funding" Ok but that's still how I play kerbal space program
    1
  433. Neil Armstrong, such a badass he managed to put the lunar module in a natural parking orbit
    1
  434. Tort lawyers solve the Kessler syndrome
    1
  435. because even in an alternate future NASA would still get saddled with the ridiculous shuttle program
    1
  436. Almost think nasa should build the metaphorical trailer park by providing a skeleton with large solar arrays, radiators, and the large attitude control systems, letting private industry park their modules there taking power and life support
    1
  437. I really really wished the forestry official would have been frank, called his request the single most moronic thing he's ever heard, and wished gohmert would immediately resign from his position overseeing american scientific leadership, instead he just thanked him for his request.
    1
  438. seems like there might have been a better way to get up the side of the lunar module base than driving a metaphorical box up to the LM, they had ropes and boxes they dropped that could be stood upon I think
    1
  439. man modern glass cockpits are amazing compared to the 60 year old cesna a friend of my dad owns
    1
  440. Scott, have you seen recent proposals to use the dark side of the moon for future radio telescope construction, and the proposal to create an internationally recognized radio quiet zone somewhere on the dark side of the moon for the purpose?
    1
  441. I think I get what's going on with the flair, that's their turbopump exhaust, it can't go out the side because they're doing differential thrust control so they NEED the thrust to be balanced not slightly asymmetrical
    1
  442. looks more like just a jobs program to keep satelite expertise within a country that has a long history of shitcanning its space infrastructure at the drop of a hat.
    1
  443. The hand made aspect is not suprising. Where I work we make advanced composites for the highest performance applications and there's massive amounts of institutional knowledge and almost everything is hand worked
    1
  444. really running hard into the rocket equation there. steam isn't great sitting around so theae are gonna need a lot of electric heaters dropping performance
    1
  445. and yet we ditched that cheap rocket for shuttle
    1
  446.  @rbrtck  he chose wherever he could get money and ended up sitting out the rest of the 40s and 50s
    1
  447. Saw Hexagon and Corona at Wright-Patterson Museum, the picture doesn't do it credit, the thing is a schoolbus parked in orbit
    1
  448. this thing looks like if lockheed decided to try and build a modern starfighter
    1
  449. they're being pulled down to earth was what I thought but its also possible nasa flew on a hotter burn out of lunar orbit
    1
  450. oh my god that has to be the biggest load frame in existence, and I've seen one that's 4 stories tall before
    1
  451. mohole cannons for early game system transfers
    1
  452. Delta IV will be out of production by the time Gateway comes around so its not likely they end up bidding that. Vulcan probably won't be reliable enough to do it either since it'd only have a few launches by then too
    1
  453. so they're like the rocket equivalent of air cooled engines, limited by their size due to the surface area requirements to manage heat
    1
  454. presumably whats left of the spacecraft is somewhere in a nasa warehouse, i can't seem to find out what happened to it after 1990
    1
  455. Not sure thats going to be a problem since the russians are probably not going to leave ISS before NASA is done with ISS
    1
  456. if they could build a coms satellite cheap enough, the DoD would absolutely be interested in this thing since they could quickly fling up a communication network
    1
  457. oh that's a lot of coolant spraying out
    1
  458. if we're going to talk ugly rockets, the N-1 generally takes the cake, its staggeringly ugly, so bad that only a handful of photos of it even exist
    1
  459. Sea Dragon, aka the big dumb rocket
    1
  460. bringing something down from orbit would be extremely difficult, especially with the ISS modules which have no doors and are 'perminantly' bolted together
    1
  461. ah yes, model rocketry, truly the best sport, would easily take manmade object out of space... easily
    1
  462. "and orbital atk which is just a bunch of srbs strapped together." when has atk not been a kerbal rocket company?
    1
  463. The rocket delivery contract almost feels like a bribe to keep spacex from contesting other contracts, the airforce just chucked them a hundred million to keep quiet while the airforce splashes out contracts to other people
    1
  464. Honorable Mention, the SM-62 Snark, its like a flying torpedo but actually was a cannon that fired the nuke at its target, and for that its completely silly
    1
  465. ya the last thing you want for your nuclear tipped missile is to flame out half way to the target
    1
  466. mostly challenger, and because using the shuttle to launch any large payloads was never really a good idea, but there's also something to consider the difference in size and complexity between 70s probes when shuttle was planned, vs 80s probes when shuttle was launching probes
    1
  467. ancient dinosaur constructed nuclear reactors confirmed?
    1
  468. a 9 meter telescope mirror would weigh like 7000 lbs I think, hard to tell back of the envalope given the exact way the 2.4 mirror was built hollow, but that's one hell of a piece of glass to get to space in one piece
    1
  469. Hammers are appropriate maintenance tools, just as using a billot of titanium as a whacky bar is appropriate for fixing complex testing equipment
    1
  470. Driving Iran to install a pro nuclear weapon pro ballistic missile hardliner into office was yet another great gift of trump unilateralism. We didn't have any assurances on the nuclear deal but iran was at least considering a more liberal path until we drove a wrecking ball into it
    1
  471. all went well apparently
    1
  472. rcs thrusters are the hardest rocket engines to build since they have to have those millisecond valve opening and closing, sit on sub optimal places for plumbing and have to work instantly from freezing whenever needed
    1
  473. seems like another problem is Venus's high gravity. Mars we can get away with landing a large SUV sized probe but the actual suspension and motors have less force to deal with
    1
  474. What do you think the name will be for the telescope that replaces the Extremely Large Telescope if built? My Guess would be the "Its just big boned!" Telescope and Observatory
    1
  475. looks like these are the live stream videos, I think they were ad hoc setup but there might be much better video
    1
  476. I think you answeres scott F's question by accident. the reason why you can't see the frozen image of every object that approached the event horizon is because it gets rapidly red shifted till its no longer visible. You could think of the ecrretion disk as what the process of falling towards a black hole looks like because the matter goes from nothing to blindingly hot, to nothing
    1
  477. thought the first rule was jiggle the power switch
    1
  478. its got clouds of boiling acid
    1
  479. "Apollo derived vehicle" Lol, like the republicans who killed the apollo program would ever vote to bring back a single nut or bolt of apollo hardware
    1
  480. its also that aluminum perchlorate is a particularly bright burning reaction
    1
  481. it feels like there's some design flaw in these airlaunched rockets, they ought to be a lot more successful. they seem to fail a lot more than conventional rockets
    1
  482. I get some serious Energia vibes from SLS these days. Everything is basically "We'll build it better in the second block"
    1
  483. its about the concentration, the highest test hydrogen peroxide you can get outside of a lab is like 9% I think
    1
  484. shit they finally launched that thing, only a few months before its warranty expired and needed reconditioning
    1
  485. I think Scott had a pretty good take on SN1, musk fans say that this was a controlled destruction, that this is intended, that musk and co are just learning, while musk detractors say don't build rockets in a field out of stainless steel
    1
  486. smashing probes into the moon isnt even a new thing, durring the apollo program all the ranger surveyer missions smashed into the moon while sending back pictures, all the saturn V last stages were sent on a collision course with the moon, i think 1 or 2 missed but the smash they gave was recorded by the seismometers left on the moon by each mission, thats just the nasa probes, the russians crashed quite a few things into the moon
    1
  487. peacekeeper was such a boondoggle as it was, at least we got some peaceful use out of it
    1
  488. damn these new engines are getting into F1 territory in terms of size and power
    1
  489. I hope whatever they do they stick a massive pile of go-pros on it
    1
  490. you're launching a lander with a rover and a rocket on a rocket to another planet to assemble a payload to launch to orbit which will dock with yet another rocket and extract the payload and fly back to earth where it hopefully won't burn up or lithobrake.
    1
  491. the first 3 James A Corey books were great but the later books got a bit too far away from the original setting and had too much focus on meglomaniacs. the first series was more tightly focused on the trilateral detant between earth mars and the others with this totally absurd alien thing coming into play
    1
  492. funny, I used to do a lot of testing with that very aerospace adhesive, it had some picky conditions to get it to adhere perfect
    1
  493. I think sea dragon would have ended up not being launched from the sea. If it was as robust as intended, there's nothing really stopping them from rolling it out on a pair of locomotives and putting it up like soyuz
    1
  494. the delayed burn probably saved the station somewhat since the module had less fuel than normal
    1
  495. feel like the problem with using the astronauts is that you've got this massive amount of money changing hands with this massive amount of expectations
    1
  496. self recycling rockets
    1
  497. I notice one major flaw with these presentation slides, they intend to put control buildings right next to what could absolutely be a horrifyingly explosive thing if anything went wrong. Realistically they ought to be putting this like a mile away on its own
    1
  498. curious mark makes a video about the saturn V guidance computer Scott Manley makes a video the next day about manually flying a saturn V Coincidence?! absolutely
    1
  499. Too bad Elon Musk is going there first and will hold those mars rocks hostage as he declares himself fabricator-general and ransom them back to earth for people and water
    1
  500. Idea Number 11: Use a nuclear weapon as the power source for a really big laser Basically the linchpin of Regan Starwars, use special bomb carrying satellites to generate a gamma ray laser to burn up enemy missiles Weird Idea Number 12: Why stop at nuking mars? there are a number of places one could nuke in the solar system to generate measurable debris and atmospheric effects, like burning a hole through the glaciers of europa!
    1
  501. the fact that orion is so completely autonomous that we can do an entire mission remotely compared to the apollo missions is pretty amazing and something NASA has never had with a man capable spacecraft
    1
  502. do mach numbers even apply when the atmosphere is virtually non existent like on the space station
    1
  503.  @aaronmicalowe  the good thing about building a space elevator on mars is there's really not much to hit that you care about if it all comes down unlike earth where you're probably going to squish a bunch of people if you had a space elevator come down
    1
  504. r3dp9 those processes while not well understood can be fully explained by interaction of various elements with cosmic rays at high altitudes and cold temperatures. The enviroment on titan is exactly the opposite of what is found underneath the earth
    1
  505. isn't this thing gonna slam into the ground at hundreds of miles per hour? the venera probes kinda needed venus's dense atmosphere to stop
    1
  506. New Rule: If the reactor shuts off and its night crew, LEAVE IT OFF. If the Reactor does anything anyone could describe as "funny" and its night shift SCRAM AND LEAVE IT OFF. If someone writes a test plan and says run this on night shift, DO NOT RUN IT Seriously its like 2/3rds of nuclear accidents happen on night shift.
    1
  507. as much as chinas space program sucks as an instrument of propaganda, it is great they're building another power flower like Mir
    1
  508. I really wonder what's wrong with pegasus and these horizontal launchers because they seem like they should be much more successful than they are, NASA has been launching stuff off of b52s for decades
    1
  509. SLS also built a rocket sized Load Frame to crush tanks like beer cans which is awesome because its like the one in my lab just giant sized
    1
  510. so spacex just massively undercut everybody and nasa believed it
    1
  511. sounds like Shuttle should have just carried MOOSE packs for each member and abandoned ship instead of trying to fly it down, or borrowed those soviet collapsing ladders they used on Mir
    1

  515. If it came to it, NASA could probably build a ship out of tungsten or Gold if they determined that's what they wanted. We build rivets out of nearly pure cobalt

  518. Proton is actually one solid tank with 7 compartments even though it looks like individual tanks while Saturn IB was actually 8 individual tanks and was only done because they had all these spare redstone tanks laying around that could be easily welded together to form a reliable little rocket. Further development like a Saturn II would probably have had a solid tank

  525. I can't say I've ever heard of it but I'd be willing to bet that Hooke only built 'his' mirror telescope just to take a swing at Newton because those two were bitter rivals and I can absolutely see him trying to find a competing design to Newton's telescope

  527. They need to redefine hypersonic, Russia, China, North Korea launch a ballistic missile "Its a hypersonic missile test" yes its technically right but doesn't really make the differentiation between a mach 5 re-entry vehicle or a mach 10 ramjet powered missile, which nobody yet has
    1
  528.  @Physco219  it seems like everyone going after hypersonic weapons are using reentry glide vehicles instead of ramjet powered missiles

  529. the shuttle knows where it is, by knowing where it isn't, unless ground control tells it where it is, so it knows where it isn't

  532. thermal heating would be less of a problem if you used Mag-Thor alloy. now the added weight from cladding your spaceplane in radiactive metal would be more of an issue

  540.  @MattMcIrvin  technically government property still. I'd imagine some variation on the current satellite recovery bus vehicle could work assuming the whole thing didn't crumple the minute you started pushing. Its an absolute mystery if the atmospheric seals let things slowly bleed out or held until they failed, but you could get it to an earth orbit but you'd need to then slow down without aerobraking. Landing it is an entire challenge unto itself

  541. Rocket Design in the 1920s: Shiny, curvy, tall and with fins Rocket Design in the 1960s: Straight lines, coregated metal, white/black checkerboard paint Rocket design in the 2020s: Shiny, curvy, and fins!
    1
  542. it would be a difficult mission to accomplish with a dragon capsule, the shuttle could do work in shifts using its airlock but an EVA on dragon would require the entire crew to suit up, and the entire vehicle to be in vacuum until the work is done, like on the apollo missions, something maybe NASA might not be willing to do again especially given the suit failures they've had in the last few years

  543. getting an optical interferometer to work on the moon without human interaction would require a lot reliability improvements

  545. its interesting/mildly worrying that a lot of these small/medium sized launchers resemble ICBMs in form though I guess we're at the point where just about any developed country could build icbms if they wanted.
    1
  546. this stupid administration cares more about prestige than actually doing things right the first time. We're loosing decades of experience every time they directly or indirectly purge experienced people from our government. The artemis 2024 landing date is so fantastically bad that it should never have been pushed.
    1
  547. If we're going to be realistic, the best payload they could deploy is a heavy rod of tungston, onto enemy positions
    1
  548. The Dragon capsule landed with 5000 lbs of SCIENCE! its actually great we're bringing some of these instruments home, when the space station is done we're not going to have a lot of flown components leftover and its not really clear if we'll try to save anything but a few small trinkets here and there

  549. Sold. This is the type of nuanced, interesting game that I like.

  550. I'm not sure there's enough carbon fiber and epoxy in the world to build entire carbon fiber rockets the size of bfr. there's intense manufacturer bottlenecks in that area as the players that own the technology only produce a dozen tons or so a year of these resins

  553. i think this will save ISS though because trumps admin wanted to really kill it in the mid decade, gateway is already a unilateral clusterfuq and we need diplomacy to get that to work. iss probably wont be chopped without very good justification

  554. those people know nothing of how shuttle worked

  555. @kargaroc386  the russians copied the STS because at the time it did look like it would have been cheap, the USSR started developing Buran in the late 70s not that far behind STS

  559. and yet 10 years on, Constellation got renamed and put up front with all the same problems and all the same politics. its always shocking how much people are willing to be fooled by a new name on a failed project just because they like the guy in charge
    1
  560. shuttle is such a great example of how nostalgia can override people's ability to think rationally about something, people of a certain age legitimately blame obama for killing something great but any amount of digging shows that shuttle was a terribly flawed execution of a design that itself was terribly flawed in concept, but they don't care to see that since they just remember the 80s and all the propaganda put out surrounding it about how the shuttle was the greatest thing ever, even as documents regarding its flawed design have come to light. killing shuttle was painful, and while SLS shouldn't have replaced it, the commercial crew program gave nasa the chance for a clean break in design they needed. I know I've certainly had this argument with those people too many times. they just don't see the difference between the shuttle's short week long jaunts to space and being able to stay in space for nearly a year at a time

  561. I know you gotta crawl before you can walk but starting your rocket program with what I can buy at walmart today is kind of funny, and also shows just how little most people and scientists really knew about rocketry back then

  563. isn't one of the slight issues with aerogravity assists, is that most spacecraft aren't very capable of entering upper atmospheres, like what happened with that one mars orbiter

  564. The russians had considerable problems with rocket fuel evaporating whenever a technician had to check the fuel

  565. "As far as I know there wasn't any criticality accidents with this reactor" no accidents but this is also the only reactor anyone has deliberately melted down and blown up to see what would happen. It was one of the last tests above ground in Nevada

  570. its sad that evangelicals have taken up this argument that god and science are incompatible given that historically the search for god's wonder has driven science with many pioneers in astronomy being of the cloth. I had a professor make the argument in a debate once and I couldn't do anything but show that science and religion can be compatible
    1
  571. god these guys can't catch a break

  572. skylab was painful because nasa had plenty of options for boosting skylab but nobody seriously wanted to save it. there were supplies left onboard and future missions could have brought more, they just wanted to scrap the apollo csm for purely political reasons
    1
  573. a lot of these look like rockets with extra steps
    1
  574. really kind of makes you wonder had we actually had a civilian lead, pure power generation based nuclear reactor program instead of just this offshoot of nuclear weapons production, would we have non-proliferable reactors powering things. Even handling the waste sounds more stable since your fuel rods are basically a ceramic already

  584. gotta love how batshit crazy some of the real life stuff was, the SCE switch is one of them, a lil switch that magicly fixes the apollo guidance system, or the fuel ignition system on the f-1A rocket engine was made using hundreds of mechanical valves and switches that would be thrown by an initial kick

  599. a slingtron always seemed like one of those ideas that work on paper but never would be possible in practice due to all the little things forgotten in simplified physics models like you mentioned friction which in such a system would be enourmous given the massive amount of weights it would have to hold and endure, bearings would rapidly heat up as it spins faster and faster
    1
  600. ejection seats on spacecraft inherantly have to compromise the spacecraft's main function of retaining atmosphere inside the spacecraft, and protect against space so to put one on a vehicle you have to engineer a system that can blow through the side of a spacecraft, and whatever shielding is there and since you want more than 1 person in a spacecraft you need to provide these engineered holes for every crew member (or be british and just give the senior most officers ejectors)
