  1. "why don't just threaten to destroy surface from space?" Because to get something from them (other than information) you have to give them exit tech. If you piss them off, they can climb the exit tech and hurt you. There are likely to be more of them on the larger planet than there are currently on Earth, particularly more than you brought with you. Despotism is inefficient.

  2. "five times" I'm counting four. 1. The Apollo-Shuttle time gap. 2.& 3. Two brief suspensions in Shuttle flights for study after each of two separate fatal Shuttle accidents. 4. The Shuttle-Crew Dragon Time gap. The Soyuz vehicle was first launched in 1967, in the middle of the Apollo program. The Soviets were, of course, the first to send a man to orbit, but previous launches were with earlier vehicles. The Russian space program has afforded mostly continuous manned access to orbit from Gagarin's orbital flight in "Vostok 1" to the present day and pioneered orbital space stations. That means there was at least one more time that Russian vehicles provided the only manned access to space, but not Soyuz.

  3. They didn't have an auto land system ready then. They did before the end of the program. They weren't confident of the performance parameters under mission conditions until they had flown a few missions.

  4.  @imanalfarizi6214  The first module was launched from Baikonur. The vast majority of the modules and components were launched from Florida in the cargo bay of the Shuttle.

  5. @Peter Evans All a union can do is threaten to strike. How is that going to prevent doing away with pilots?

  7.  @hadeskiller1  "Joking about hundreds of people with families being potentially out of work for the sake of a meme is funny, right? I guess I shouldn’t be surprised since all the internet space enthusiasts aren’t actually involved in the space industry developing these technologies" You've backed into the essence of the problem with Boeing/ULA, and too many of the nation's federal programs. It is morally wrong to regard our space program as a jobs program for well-connected aerospace companies. (Just as it is wrong to regard our education system as a jobs program for teachers and the teachers' union, as the current system does). When a particular group has had something for a long time they begin to think of it as theirs. "What's good for GM is good for America." If Boeing's space division ever does recover and become a LEGITIMATE part of human progress in space again, it will be because Elon Musk and a few others lit a fire under their posteriors. Men of goodwill among Boeing's employees and subcontractors agree, along with anybody who believes in the future of man in space or simply believes in honest dealing in business and government. The basis of the humor of the thread opening statement is not cruelty, but the defiance of entrenched corruption with the truth.

  8. The same way. You see them zipping them up in the video. They only had them on for launch, spacewalk, and reentry. You will notice that the maestra didn't have hers on for the concert. It makes the violin harder to play. No. Why would they? All three needed to don their suits during the SPACEWALK, because there was no airlock: opening the hatch means depressurizing the cabin, not during the whole flight. They wore the suits during takeoff and reentry as a safety precaution, and during the spacewalk out of necessity.

  9. You are discussing philosophy. This discussion is about (known) aerospace tech, applied to a different environment. Even if you're right, (And how can we establish whether you are?) you're off topic.

  10.  @tg1431  "because the cost of Nimitz - Kittyhawk Class carriers is 1 Million A day." A lot of that is pay. You can run a rocket carrier cheaper because it's not a warship, it doesn't need a crew of thousands.

  11.  @bradnewsbear  Well if you're the sort that would object to calling the condition on Ring City or an O'Niel Cylander "artificial gravity", its not going to be your sort making this happen. We don't insist on being wrong, we just don't like trolls.

  12.  @NochZvezd4  The joke has nothing to do with the earth being flat. It assumes that the Earth is Earth shaped and that down is from the North Pole to the south pole, as it is for a globe rather than a planet, instead of toward the center as it is for planets.

  13. The high inclination orbit also makes ISS useless as a staging area for missions to the Moon and beyond. For that you would want it in the ecliptic plane.

  14.  @DavidOfWhitehills  "And yet you have no problem with 'thunkit?" You knew "thunkit" wasn't standard English. You apparently didn't know "must of been" isn't. The latter is an abomination and must be destroyed. Where it comes from is folk hear contractions like "must've" "could've" "should've" (contractions of "- have") and mistakenly HEAR them as "- of". It's not a usage, it's a misunderstanding.

  23. Are you joking? Show me a spacewalk photograph with stars. In a well lit foreground you can't see stars in the background. Tell me this is not the first time you've heard this. And if it isn't, why are you trolling?

  24.  @johncrowerdoe5527  Perhaps not water because using a cryogen would test it on closer to operational conditions.

  25.  @Jesse-cw5pv  1. We don't need higher tech than them to reach them before they reach us if they have twice the orbital velocity we do. 2. Numbers DO matter. Take a modern Marine Expeditionary Unit and supporting amphib flotilla supplemented with a bunch of cargo ships and try conquering 17th century North America and watch your ass get handed to you. You aren't carrying your entire military with you, you are carrying an expeditionary force. You lose. You are envisioning a situation (whole modern US military vs 17th century native Americans) where the invaders have near numerical parity in addition to a tech advantage. That is not the scenario being examined.

  26.  @AsbestosMuffins  "the other is a politcian seriously asking if we can just move the move the moon" [sic] Of course it is nothing of the sort. The question is obvious irony. What is the point of media figures and YT commenters pretending not to understand irony? And who do you think you're fooling by doing so?

  28. It took all the engineering SpaceX could muster to make soft cryogens (oxy/methane) work with fiber composite tanks, to save weight. At the current state of art, hard cryogens like hydrogen require metal tanks. Hydrogen is also bulkier per unit energy than methane, and burned in molar mix with oxygen, methane produces two molecules of water for every molecule of carbon dioxide. It is semi-clean, like natural gas, same stuff. A jet airliner in it's lifetime will insert more carbon into the atmosphere than NASA, SpaceX, and Virgin combined ever will in the forseeable future. When you've shut down civilian aviation, call me and I'll still have your travel plans booked.

  37. Speaking of space salvage, aren't their enough large pieces floating around now to send up a smelter and start recycling the orbital junk into parts for larger space stations and spacecraft?

  40. Yes, having the hatch open explosively and blow out every loose object in the cabin would be suboptimal.

  41. Do you mean the bends? Nitrogen narcosis happens when you're breathing a partial pressure of 4 atmospheres of Nitrogen or more. It's a problem for divers that must equalize the high pressure in deep dives. They mix noble gasses in the breathing mix to avoid nitrogen narcosis and keep the Nitrogen pressure low. Beyond a certain point, they need a mix of 3 or more gasses. Not an issue in spaceflight, until we need to use a flexible spacesuit on a planet with more than 4 atmospheres of surface pressure, or unless the life support system malfunctions and lets in too much Nitrogen.

  42. We are going to have to learn how to STICK BUILD structures in orbit out of metal extrusions. Once we build a big enough dry dock, we can build structures within it at our leisure. We need to learn to recycle orbital debris in situ for materials (there is a lot floating around and it is safer to collect it anyway, it is MASS IN ORBIT, which is otherwise hard to come by).

  43. There is a common misunderstanding that asteroids are all the same thing. Also, Manley's projection seems to assume this trick is easier for larger objects. The opposite is true. With a maximum spin rate of 2 RPM, you can get useful gravity with natural materials, like basalt and granite. Nobody is going to try to spin up a slagpile. This is a "straw man" post.

  44. Who said they can't remove the suits? If they need help to put them on and take them off, they have it. The maestra did the concert in the capsule in orbit and outside the suit, so obviously they CAN take them off. All three needed to don their suits during the SPACEWALK, because there was no airlock: opening the hatch means depressurizing the cabin, not during the whole flight. They wore the suits during takeoff and reentry as a safety precaution, and during the spacewalk out of necessity.

  50.  @slckb0y65  Because old integrated circuits didn't have components as small as modern ones, and thus weren't as susceptible to radiation.
