Note that this only applies to low earth orbit. Geosynchronous spacecraft don't re-enter; they instead are retired to the “graveyard”, a supersynch orbit about 500 to 1000 km above GEO.
- ge96 9y agoCurious is it safer to not just fly them off into space (requires more energy) or they want to know where it is rather than unkown?
- wereHamster 9y agoRequires too much energy. https://physics.stackexchange.com/questions/29785/is-the-escape-velocity-at-geosynchronous-earth-orbit-0km-hr https://physics.stackexchange.com/questions/29785/is-the-esc...
- ge96 9y agoNot sure if I understand right to get to that circular orbital velocity 70% of escape velocity is required so since it's still in orbit it still has that 70% then is 1% enough or do you need the other 30%? And even if it's just 1% that's probably a lot with regard to mass shed from off the pad. Laser space brooms haha. Or drone ion thrusters that can latch onto things and push them. Not sure if there is an exothermic rocket that is electric with high impulse (not take forever) The drone thrusters is from the show The Expanse haha
- wereHamster 9y agoIf you're flying 70m/s at a stable circular orbit then you need to accelerate to 100m/s in order to escape. That's an increase of 42%.
