Comment on NASA selects SpaceX to build deorbit vehicle for International Space Station
homesweethomeMrL@lemmy.world 2 months agoGood point, if they’re sending a rocket up there anyway, why not just push it away from earth rather than towards it? Is it because it’s in LEO and there’s a ton of other satellites farther out?

Way too much dV to leave earth

There’s no need to leave earth, just lift it into a medium earth orbit. There are literally thousands of kilometres in between low earth orbit (where there are lots of communications, spy, navigation and weather satellites) and geosynchronous (where there are lots of communications satellites), and outside of those two there’s virtually nothing there

Still way too much dV. Deorbiting might be a few hundred m/s. Getting up to medium earth orbit could easily be 1000-2000 m/s.
