spacex - Why will Starlink satellites use krypton instead of xenon …
It's the same reason SpaceX often does things differently: Krypton is a lot cheaper. The satellites are designed to control costs. For example, each will maneuver with Hall-effect thrusters—ion thrusters in which propellant is accelerated by an electric field.
What happens to the Falcon 9 second stage after payload …
Jan 15, 2015 · SpaceX would love to recover the second stage, which they had planned. But it sounds like they have given up on that. Transcript - Elon Musk at MIT's Aero/Astro Centennial (part 1 of 6) [What about the second stage?] The next generation vehicles after the Falcon architecture will be designed for full reusability.
spacex - What computer and software is used by the Falcon 9?
May 29, 2015 · SpaceX uses an Actor-Judge system to provide triple redundancy to its rockets and spacecraft. The Falcon 9 has 3 dual core x86 processors running an instance of linux on each core. The flight software is written in C/C++ and runs in the x86 environment. For each calculation/decision, the "flight string" compares the results from both cores.

spacex - What is the advantage of catching a rocket booster with a ...
Oct 17, 2024 · All other practical aspects be damned, SpaceX did just successfully maneuver a massive >200-ton steel vehicle through the air faster than sound, safely returning it to its site of launch after delivering one of the largest spacecraft ever built on its way, and then caught it midair with massive robotic arms for later reuse. If absolutely ...
spacex - What are the differences between a standard Merlin …
Apr 19, 2015 · The biggest difference is the nozzle.For optimal performance in vacuum, you want a much larger one. According to Spaceflight 101, the chamber pressure is the same, but the expansion ratio (throat area to end-of-nozzle area) is 7 times larger in the vacuum variant, which (if correct) implies about 2.7 times the nozzle diameter if the throat is unchanged.
spacex - How much fuel does the Falcon Heavy use? What is the …
Dec 10, 2018 · SpaceX doesn't publish this, but Spaceflight101 usually has pretty good estimates for this sort of data. Core and boosters, each: LOX Mass 287,430 kg RP-1 Mass 123,570 kg. Second stage: LOX Mass* 75,200kg RP-1 Mass* 32,300kg
spacex - How to understand "rat" moving on Falcon 9 second …
Incidentally, in the absence of much, much more evidence, suggestions that this is a live rat on a filming set at low altitude, and that SpaceX's launch videos are faked, are not credible to me. Commercial, profit-driven corporations appear to give SpaceX a great deal of money to put expensive things into orbit.
