I take it that not all of the Raptors are going to gimbal?

They recently celebrated the 100th roll-off of a completed Raptor engine, and also eliminated the gimbal / non-gimbal variants. They'll be churning these things out insanely fast I imagine. Well, insanely fast for a rocket engine.
Hey Jeff, wen BE-4? :P EDIT: <samp class="EmbedCode-container"><code class="EmbedCode-code"><blockquote class="twitter-tweet"><p lang="en" dir="ltr">100th build of a Raptor engine complete <a href="https://t.co/ymoJmV820Z">pic.twitter.com/ymoJmV820Z</a></p>— SpaceX (@SpaceX) <a href="https://twitter.com/SpaceX/status/1419738163988205575?ref_src=twsrc%5Etfw">July 26, 2021</a></blockquote> <script async src="https://platform.twitter.com/widgets.js" charset="utf-8"></script> </code></samp> |

So a question for those who know more about this:
Mars has almost no atmosphere and an explosive decompression is always a moment away? How do you colonize that kind of environment? One defect or stress can result in everyone dying pretty quickly, no? |

In all seriousness, I think they've had a LOT of experience with ISS and "explosive" decompression is mostly a movie thing. IIRC, the ISS is currently losing 1lb a day of atmosphere through leaks. A recent Soyouz was found to have a hole rooted in a manufacturing mistake. The spacecraft survived launch and docking with the hole. Leaking atmosphere is just life in space. EDIT: References... https://www.nasaspaceflight.com/2018...airs-continue/ Couldn't find the 1lb per day loss I mentioned, but assuming my Duck-Fu is just not strong today, but there has been a known leak for a year... "The air leak in the Zvezda module, which provides living quarters for crew members and life support systems, was detected last year. It poses no danger to the crew but persists despite attempts to fix it by sealing cracks." https://www.reuters.com/world/europe...le-2021-07-31/ |
But yes, people would have to live in pressurized environments. The pressure on Mars is something like .09 PSI and on Earth it's 14.7 PSI. Quite a delta P although I'd imagine that we wouldn't pressurize at 14.7 on Mars.
And, after a while, there would be a large volume of air in that environment, so there'd be some time before the Martians would be sucking Mars' atmosphere. |
TPS install is also moving quickly, although it looks like they've been having issues with the curves on the nosecone section...
