  1. Thanks for another wonderful video! The result for Astra is disappointing but your analysis of the launch is first rate. I hope they figure out what went wrong and get the next one into orbit.

  2. Yay for Cosmic Girl and LauncherOne! A well earned success. And thank you Scott Manley for this very educational video telling us what's going on. An epic power slide through the atmosphere, before blasting up through the stratosphere and into space sounds pretty darn cool.

  3. The Opportunity mission was a tremendous success by every standard. Congratulations to everyone who built and operated it! Opportunity and Curiosity also demonstrate the utility of the autonomous or semi-autonomous rover as a scientific instrument. There's no reason we shouldn't always have two or three rovers up there, roving around and steadily learning more about Mars.

  4. Thanks for the update, Scott! As for the SLS... well, stuff breaks. It isn't a surprise that something went wrong, the real cynical "surprise" is that it took so long to finally get to this test. Everything about SLS seems to be in super slow motion, like a development program from a different era.

  5. Thanks for another great video!

  6. What I'm getting from this is that Rocket Lab, in an effort to fend off competition from SpaceX, is going to be competing more directly with the Russians. It's pretty bold to go up against the oldest and best tested rocket in the world.

  7. There's only so much the magnetic field can do. If you point an extremely high velocity stream of radionuclides right at the Earth that's too much mass and speed to overcome.

  10. I'm sorry that happened to you. It sucks. On the bright side though, it's pretty cool that you met a fan in Spain who helped translate for the police. You've got fans everywhere it seems.

  11. No doubt there's one out there. Hopefully it's not too far away. (Where "too far" is defined as there being no way to send a probe there and receive data back in our lifetimes.)

  12. Yes, you're right. I used the wrong term, it would actually be convective cooling that doesn't work so well on Mars.

  13. Thanks for a great Christmas video! Also, it's nice to meet Lucky Manley. As for the story, it is a Christmas miracle, but of a peculiar kind. Despite their best efforts, Soviet rocket engineers fail to kill two dogs. Hooray?

  14. It's funny but also true.

  15. These updates are incredibly informative! The amount of information Scott gives us is so high it makes me feel like I know what I'm talking about when I tell other people about this stuff. Just as long as they don't ask questions... "What's a 'Fluid Hammer' again?" "Uhhh.... Let me check YouTube and get back to you."

  16. "...there's new space, and then there's old new space, and Exos are a new space company that has roots in the old new space..." I actually understand what you're saying perfectly. Old space is government agencies like NASA and Roscosmos and ESA. Old new space is companies like Armadillo that got started in the 90's, and new space is all the current companies that started in the 21st century, like Space-X, Blue Origin and many more. This is a fun video. Thanks for telling us about Exos and what they're up to. I hope they work through the problems and develop SARGE into a profitable concern.

  17. You could pack the Gateway station in the Lunar Lander and assemble it when you get there. Or you could land a Starship remotely and have a ready made moon base waiting for the astronauts who arrive on the second flight. If you replace the SLS with Starship there are so many possible configurations for Artemis that involve fewer launches and less money than the current plan. But it all hinges on the concept of orbital refueling. SpaceX absolutely has to get that nailed down to make everything else possible.

  18. If they can figure out what went wrong, that information may not be useful to science as a whole but it'll be very useful to ISRO if and when they build another lander.

  19. They're not dead, just changing jobs.

  20. Oh wow, this is a great video! Thank you for making it. What a fascinating thing. It's like a secret history. The British had their own rocket program that made its own unique design choices (that have never been replicated since), and it sounds like things were going pretty well. Then they just... decided to stop.

  21. Love these space news updates!

  22. Presumably anything being transferred along the cable will be much smaller than the total mass of the system. Would it change the center of mass that much?

  23.  @RCAvhstape  Exactly. Good point.

  24. Congratulations! Maybe someday futuristic asteroid miners will claim Scottmanley and use it as the basis for their family fortune.

  25. Masten seems like a cool company. Good luck to 'em. It'll be great if they do land on the Moon in a little less than three years from now. Love that Flight Alumina Spray Technique! I remember a similar idea in Stanisław Lem's 1964 science fiction novel "The Invincible." Except in his book the rocket was nuclear powered and it sprayed out some crazy sci fi substance to harden the molten crater before it landed, not good old aluminum.

  26. It would be wonderful to repair Arecibo, but it appears to have reached the state where all the cables would need to be replaced, and if I understand correctly that's almost as hard as rebuilding it completely. It's unclear to me why the Aricebo telescope has so little domestic American support, since it's a literally one-of-a-kind instrument with an incredibly distinguished history of accomplishment - and as you point out in the video, there's no similar replacement available elsewhere. So I really hope someone builds a replacement dish. It could be the US, or a coalition of different countries, whatever, just so long as science gets that capability back as soon as possible.

  27. It looks tighter than it really is due to the display being two-dimensional. If we could see it in 3D it would look more dispersed.

  30. Thanks for another great video! This was a really interesting and useful look back at how we got here. If there's lesson to be learned, it seems to be: the cheaper your manufacturing process, the more launches you'll get to make. More launches means more failures, but it also means more opportunities to hunt down and fix mistakes so they won't happen again. The bigger, more expensive programs either didn't get off the ground, or in the case of Boeing, did launch but with unsatisfactory results. Meanwhile SpaceX has been building (and sometimes losing) cheaper rockets at a much faster rate, and making more progress than everybody else.

  31. That explanation was really simple and easy to understand. You're exceptional at this sort of thing, Scott. Thank you for the video! And thank goodness they figured it out. This is the way it should be done - everything transparent and out in the open so everyone knows the problem has been addressed and there's no chance of it happening again. It's too bad they'll have to install new burst valves every time they want to reuse the Crew Dragon, but that's a small price to pay in exchange for the added safety.

  32. So only for manned missions?

  33. Thank you for this video! Ever since the test I've been waiting to see what Scott Manley thought of it. Your insights are a vital part of the process now for anyone who wants to be truly informed about space news.

  34. Thanks for another great video! You've summed this development up really well, and I can't think of anything to add except amplifying what you've said. This new development doesn't appear to be a good thing. The race to get to the Moon by 2024 seems like it could be a repeat of the Apollo program, with little left to show for it afterward. LOP-G isn't the best idea, but at least it's semi-permanent architecture that will help make future missions easier, and become a platform for scientific research. I hope that NASA ultimately goes back to their original conception of using LOP G for a Lunar landing in 2028, but I guess that's up to the politicians.

  35. So cool! I've never even heard of SOFIA before, but it sounds like a great instrument. It's also fascinating how rugged those old airframes from the 1950's-1970's are. They can just be renovated and reused over and over, for all kinds of purposes.

  36. Thanks for this summary! I'm one of the nitpicky people who believes that the decade isn't over yet, but it's still great to look back and see how far we've come. But that's nothing compared to what's coming. The next decade is going to be awesome!

  37. Awesome review! Thank you for doing this video, Scott Manley. And a very interesting game I didn't know anything about. There are so many amazing games I'm gonna need to live two or three times longer than normal just to try them all.

  38. I love that you took the time to seriously discuss the concept of water powered rockets and finished the video with the "microwave cavity thruster," which sounds like it could be a really cool technology in the future. Most people would have just made a video criticizing the obvious scammers at ARCA and left it at that, but you went the extra step to find something positive and fun to talk about in the subject.

  39. I wonder what he may have achieved if he was born today.

  40. Watching the boosters land successfully still amazes me. To think that something so powerful could go so far and then come back safely and on schedule, all on its own, that never stops being cool. This failed landing is too bad, but no doubt it will give the SpaceX engineers some insight they can use to make the boosters better in the future.

  41. Thanks for another great video! Here's hoping they don't have to use any of those safety measures...

  42. NASA's Artemis plan is very exciting! But, well, I've been excited by Artemis plans before that never happened, so it's difficult to believe they'll get everything done on schedule. Hopefully they will! But when real life meets human plans, real life always wins and things get delayed and changed. If they keep getting the funding they'll make it back to the Moon, but probably not as soon as 2024. The real question is if Congress will keep funding Artemis when the goals start to stretch out forwards in time.

  43. Thank you for making this amazing video! It's the most fascinating thing I've seen all day, by far. So the rate beacon failed, which meant the guidance computer was only getting information on the rocket's rate of acceleration from the ground based rate radars, which meant it couldn't properly calculate the Doppler shift, and from that the velocity. The ground radar would return a range of values, some of them noisy (close to but not quite the "sweet" value) and some of them measuring the rocket's vibration along with the linear acceleration. Because someone made a typo (missing the overbar) when giving the equations to the programmers, the guidance computer used all of these acceleration measurements instead of using only an averaged "smooth" value. This made the computer think the rocket was going crazy, so it ordered a number of severe course corrections which actually made rocket lose control and have to be destroyed. Is that about it?

  46. That's amazing! You should write a book (or at least an essay) on this. A lot of people would love to read it.

  48. I'm afraid this video has gone completely over my head. Even with more than one viewing I only understand bits of pieces of what you're saying - but I still really enjoyed it! It's very relaxing to listen to someone who really knows what they're talking about as they take you through a subject you almost understand. It really focuses the mind on 1960's computers instead of present day problems. So thank you for another great video, Scott Manley! The research you do on these videos is incredible.

  49. Yes, it seems like the kind of rocket they could use when they don't need to take off again. Land one of those and make it into an instant base or industrial facility. They might need to tip it over first, though...

  50. Very cool video! Thank you for making this. Which is kind of the way I feel about the ISS. Very cool. I really hope Axiom gets their modules up there, so the ISS can give birth to a new station that will hopefully last for many years to come.
