  1. Those graphics are fun sometimes. There was a graphic for the now-abandoned Ares V rocket (which morphed into SLS) which showed it with black and white pattern similar to the Saturn V, obviously a ploy to drum up enthusiasm for the project by making it look related to the coolest launch vehicle ever flown.

  2.  @OCinneide  They didn't change it, they just reworked it to make it more fireproof while changing procedures. Prior to launch, the cabin atmosphere was pumped up with normal air, and after launch as the air leaked out they would replace it slowly with low pressure oxygen. Apollo 1 was a firetrap because the cabin was filled with O2 at higher-than-sea level pressure, along with faulty wiring. As for ASTP, I think that model of Soyuz had a low pressure system, not sure.

  3. If Hubble loses attitude control there won't be any safe way to dock with or grapple it, and thus no safe way to boost or deorbit it. NASA needs to do something while they still can, find a way to attach a propulsion module to that docking ring the last service mission left there.

  4. That video of the helo's shadow on the ground flopping around looks like the bat from Atari 2600 Adventure game.

  5.  @r3d0c  Your snark is unappreciated and misguided. Every mission has risk associated with it, no matter how many brains are involved and how much money is spent. And if you ask any one of those scientists and engineers, they'll all tell you that. Let's not pollute Scott Manley's comment section with the same toxicity the rest of the net has.

  6. Really? How many square rockets does the US fly?

  7. Voyager is still within Sol's sphere of influence, so it has not entered galactic orbit yet, but will when it gets far enough away.
    2
  8. Yes, but close enough. Unless NASA restarts the Voyager program with some fresh new vehicles...

  9. This abort system is better than the one on the 737 Max.

  10. Some people only watch auto racing for the crashes. Falcon 9 landings are probably about the same, only no people get hurt when one crashes.

  12. Resistance is futile.

  13. Falcon 3.0 not only had a thick manual, there was an actual guidebook for it written by an actual F-16 pilot. Lucasarts' Secret Weapons of the Luftwaffe was a killer WWII flight sim and the manual was like reading a history book of aerial warfare in the 1940s. The 90s were the good old days.

  14. Dewars 12 scotch whiskey. Did that have a role in forgetting to turn the lights on? ;-)

  15.  @georgejones3526  I imagine an aerospike engine landing and getting stuck in the mud.

  16. Great video. The mention of a space zeppelin reminds me of Iron Sky lol.
    2
  17. Sucks that they lost it again, but that camera angle looking up at these things as they do that belly skydive are among the coolest looking footage ever.

  18. The old school Atlas rocket was almost SSTO with a manned Mercury spacecraft on it. We know how to build SSTOs, we've done the math, we just haven't found an economic reason to do so.
    2
  19.  @PlanetEarth3141  Or the origin of the Borg...

  20. Awesome to see the mighty 747 finding new work.

  21. My guess is you're not an engineer yourself, nor do you know any engineers who work on stuff like this, certainly none who work for Boeing.

  22.  @digi3218  I wasn't making excuses. Just pointing out that losing your spacecraft in...space...is not at all uncommon. Didn't read your long post, sorry.

  23.  @bearlemley  Well, it looks like reverse engineered alien technology, so I'm gonna go with Lockheed Martin for the Jupiter II. But the reason they got lost was Dr. Smith, so he might be a Boeing employee.

  24. The Canberra family of aircraft has a long and storied history. I believe both the English Electric and Martin versions saw a fair amount of combat in Vietnam in service of Australia and the US.

  25. Zubrin is like Elon Musk, but without the money.

  26. Looks like Ron Howard nailed the look of leaking fluids in Apollo 13.

  27.  @martinilopez1  wow, who_pissed in your corn flakes this morning?

  28.  @martinilopez1  So you're apologizing for calling me an a**hole, then?

  29. STS was more expensive and dangerous than we had hoped, but it turns out there were good reasons for wanting that capability. Fixing Hubble (or even retrieving it) was one.
    2
  30.  @danielpassigmailcom  The Titan rocket family had a payload size and capacity approximately that of STS. I think there were others.
    2
  31.  @ericg7044  Since they merged with MDD
    2
  32. Shuttle was designed to return with payloads, including some fairly heavy ones like Hubble. Columbia retrieved and landed with the LDEF, which was about 10 tons IIRC. Not sure about this one.

  33.  @RG-zt4cn  I don't understand the question. Nukes.

  34. FAA is damned if they do and damned if they don't. On one hand they are too conservative-minded and ruin the fun of the daredevils, on the other hand they catch hell for being too lenient and get accused of being in bed with industry, etc. Nobody ever likes the kid who gets to be hallway monitor. Imagine the hell they'd catch when one of these rocketships crashes into a group of spectators and douses them with burning rocket fuel. We've seen it happen at air shows and it resulted in air shows made of tiny dots doing maneuvers far away. It's a shame about the rocket racing, it did look cool but you could see it getting watered down and chipped away into oblivion.

  35. Looking out that window it reminds of how gutsy Young and Crippen were to fly STS-1 in an unproven spaceplane design trusting the math.

  36. There exists a GPC MFD add-on that simulates the energy management displays which really help you to manually fly the orbiter back to the landing site.

  37. They aren't tourists, they are Italian air force and they were there to do a job first and enjoy themselves second. Presumably, the paying customer is the Italian government, not the passengers.

  38. I don't understand why they want to sink the Starship booster. Wouldn't they want it to float so they can retrieve it and examine it?
    2
  39. I wonder if the North Koreans are aware that all of their missile names are penis jokes in English.
    2
  40. I don't know if you can call it "innovation" when it blows up four times and never works right even once, even obliterating its own launch pad in the process.
    2
  41. The flattards will question the size and distance and motion of the sun, blah blah blah. To idiots like them, the wonders of the universe will forever be out of reach. Pretty sad, really.

  42.  @Xatzimi  January in Florida is not usually as cold as it was on that morning. That said, a reliable launch vehicle should be able to operate in cold weather. STS shouldn't have had any problems with it if they hadn't cut corners to get the schedule on track.

  43. 8:45 there is an anime character on Scott's computer in the background who appears to be performing the "Tickling the Dragon's Tail" test with a nuclear bomb core. WTH is that all about?
    2
  44. Scott, since you mentioned the Soviet spacecraft, maybe you can do a video on the one that crashed in Canada in the 70s and basically scattered its reactor core over the northern wilderness.

  45. Avionics hooked up on the ground to act as if they are in flight is what we used to call a "bench bird".
    2
  46.  @Canada_Dominium  No, it wasn't a Dyna-Soar. It was some kind of fictional lifting body that could seat three people, including the rescue pilot, which was launched on a Titan rocket similar to Dyna-Soar. That fact that they didn't have room for all three marooned astronauts was a major plot point.

  47.  @frabe81118  It's being pre-empted for a special showing of Seattle Follies.

  48. I vote for the Triton mission, or anything Neptune related.
    2
  49. First surface to air missile, yes.
    2
  50. At least one variant of the Atlas missile had a blunt nosecone as well; I'm guessing that was a reentry heat shield. And yes, it looks wrong.
