https://twitter.com/stanshull/status/1529969326421291008If Starlink Gen2 is 30000 satellites (spacenews.com/spacex-goes-al…) it represents 36000 tons at launch in total. Or 240 #Starship flights (at 150t/flight). 2/
https://twitter.com/pbdes/status/1524785266296242177First we read that the January 2022 launch yielded 2.1M$. With a total mass launched of less than 30kg, for 6 cubesats deployed (according to @planet4589 here: planet4589.org/space/gcat/dat…) that is a whopping >70k$/kg to orbit. Hardly a bargain. 2/
https://twitter.com/elonmusk/status/1482424984962101249I know that this is not a popular opinion, but I can only see two (non mutually exclusive) reasons for this: 1) Falcon9 is too expensive; 2) Falcon9 turnaround time is too long. Tu put it short: it is not as effective as required. 2/
