During Tim Dodd's interview with Elon Musk in 2023, Musk stated that the autogenous pressurization of the LOX tank was achieved with a feed from the oxygen side turbopump introducing small amounts of ... |

Now that a Falcon 9 first stage has successfully landed after a launch mission, I want to know how the first stage can avoid burning up when coming back down to earth.There doesn't appear to be any ... |
I'm becoming interested in how Mars missions are planning their landings. One aspect I see brought up time and again is Mars' awkward atmosphere - 'just enough there that you have to care about it'. ... |
I'm writing a story about Mars and I'm really confused as to how one should use the word 'Sol when talking about the passage of time there. For example, Would one say to a colleague: "Today is Sol 345,... |
Cape Canaveral and Kennedy Space Center are both at pretty much the same location in Florida. I do not understand why they are referenced separately in media. How much are they separate entities? Is ... |
