SpaceX Starship : Texas Prototype (s) Thread 25 : Discussion
网页2023年7月7日 — Re: SpaceX Starship : Texas Prototype (s) Thread 25 : Discussion. So the plan is to cut the booster thrust back to some non-zero value while the SS engines are cranking up to a currently planned 50%, then separating. Once SS is clear the booster will gimbal for the flip with uninterrupted thrust.

What happens to the Falcon 9 second stage after payload …
网页2015年1月15日 — 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 are the differences between a standard Merlin …
网页2015年4月19日 — 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 …
spacex - Why will Starlink satellites use krypton instead of xenon …
网页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.
spacex - What computer and software is used by the Falcon 9?
网页2015年5月29日 — 196. 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 …

launch - Why is SpaceX considering Methane as fuel for their next ...
网页The reasons CH 4 is a front runner for SpaceX's Raptor can probably be attributed to four factors: Methane does not coke (polymerize) at the operating temperatures of a rocket engine – it's coking point is roughly twice as high. This makes it easier to make an engine reusable and re-usability is a key SpaceX objective.
spacex - How to understand "rat" moving on Falcon 9 second …
网页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.
