astronomy fag seething over starlink is comedy gold, these queers can't see that lower the cost to orbit enough makes all their precious ground telescopes totally irrelevant in the medium term-shit, once additive manufacturing and asteroid mining take off in 20-30 years, we can build arrays of monstrous 40 meter telescopes to resolve mountains on the planets of alpha centauri

Real astronomy fags cheer on starlink and SpaceX. It sucks short term but most are huge space nerds.

I'd have to check the /sfg/ and search through it to find upcoming launches. A dedicated thread is way better, I catch launches all the time while randomly lurking.

are they designing Starship to be more weather resistant? If anything, I thought it would be more fragile.

It will be more wind proof due to not being a pencil thin.
