Even if use is on Earth vehicles and plumbing systems I always like to hear on YouTube videos what the proper sealant is if any. |

Helium is leak-prone due to the tiny atoms and extremely expensive.
Is the helium only used to pressurize fuel? If so, why not another noble gas that is cheaper and less prone to leakage? Can't use nitrogen or hydrogen due to metallurgy, but why not argon? It's free (relative to helium), inert, and I don't think it has any detrimental metallurgy impacts... |

The F16 EPU is fueled by H70 (hypergolic fuel) but is pressurized using nitrogen with no issues. The system does need periodic recharging of the nitrogen but it also isn’t made or sealed to space hardware levels. Argon is used for cooling seeker heads on older AIM9s. It is prevalent in aerospace applications also. |

Quote HistoryQuoted: When a Soyuz at the ISS had coolant leak I had visions of SpaceX sending up Isaacman and Musk (Musk secretly) to the ISS to bring back that Soyuz crew. After they open the hatch to the ISS Musk floats out and proclaims something like this: "Did someone call for a space Uber?" I think Musk would have to go through some training to be qualified to do that. But something like that would probably be his Magnum Opus of trolling.

He does not need to be an expert on capsule systems. Isaacman probably is already. Imagine that it take three months to get a Dragon ready along with Dragon IVA suits for Butch and Suni allows plenty of time to get a suitable amount of clandestine training. The ISS surely can accommodate them for that time. |

I remembered seeing a trailer for it when it came out and I had the memory that it was the story of a guy like Musk who had to go up on his own rocket ahead of schedule to help in the rescue of astronauts from Mir. When I read the plot synopsis I found that was… ah not the movie I was thinking of. It would be funny as fuck if the completely different movie I had in my minds eye turned into a real story.

I remember talk about getting crew back when the Soyuz sprung a leak and that the big problem was that the Soyuz suits were not compatible with Dragon systems. So they thought that they might have to fly up Dragon suits until the Russians sent up a working Soyuz.
Does anyone know if the Boeing suits will work with Crew Dragon? I hope they would but I don't expect they do. |

Boeing Starliner docks with space station after encountering new issues
" During the final hour of their approach to the space station, Starliner’s crew began to manually pilot the spacecraft in a planned test of Starliner’s manual flight control capability. Five of the reaction control system thrusters failed on the service module, but the duo was able to get four of the thrusters firing again after conducting hot-fire tests. These smaller thrusters are used as the spacecraft moves closer to the space station so it can make more finely tuned changes to its trajectory. There are 28 total such thrusters located on the service module, or the lower portion of Starliner, which will not return to Earth. The space agency said late Wednesday in a post on X, formerly known as Twitter, that two additional helium leaks had been detected on the vehicle. One helium leak had been discovered prior to launch and deemed acceptable. “Helium is used in spacecraft thruster systems to allow the thrusters to fire and is not combustible or toxic,” according to Boeing. As of Thursday morning, two of the three leaks have been corrected, according to a live NASA broadcast." |
