Per the article, Starlink runs 8k satellites with an average life of 5 years. They launch in payloads of 20-40 satellites. That's 50+ launches per year if everything goes perfectly. About a million pounds of kerosene per launch. Plus everything else that goes into the rockets and satellites. Then the pollution impact from the launches and reentries. Then the eventual need to clean up LOE to avoid Kessler Syndrome. So yeah, well understood ground tech may be cheaper over the lifecycle. At a minimum, it should be a reasoned choice, not environmental debt pawned off by the richest man in the world. |

Quarter of a million pounds kerosene per Falcon 9. Zero for Starship, which burns methane. (And thus emits pure methane, CO2 and water vapor.)

Not a thing. (Search this comment thread for the term. There are good answers on the current state of research.)
