How much krypton (fuel) is there for the krypton-powered ion thrusters on Starlink satellites and how long does it last?
1 Answer
We don't know exactly how much krypton starlink satellites have, but some guesswork based on the orbital maneuvers performed says that they would need ~2.5 kg of fuel. See https://space.stackexchange.com/a/36471/40045 for more information.
