Starlink satellites use krypton as propellant.

This answer roughly estimates 2.3 kg of Krypton based on a total delta-V of 190 m/s and an exhaust velocity of 20,000 m/s.

But how close is that to reality? Is it known how much propellant is loaded into a Starlink satellite at launch?

    $\begingroup$ I think it would be helpful in tailoring the answers if you could explain what, precisely is unclear to you about the information provided by Google and Wikipedia, and what you did and didn't understand about the results of your research. That way, you prevent people wasting their time by repeating things you already know, or things that you already found and didn't understand. $\endgroup$ Nov 26, 2020 at 20:54

  • $\begingroup$ Most of an answer here en.wikipedia.org/wiki/Starlink#Satellite_revisions though does not talk about how how much xenon. $\endgroup$ Nov 27, 2020 at 7:14
