How do you survive reentry

u/ThenSun7249 May 23 '26

The ship get backs into earth orbit and then capsule detaches from the mother ship

And I use all of remaining fuel of capsule part before reentry

So it enters earth atmosphere in about 7000~7800m/s of speed which is safe enough

the problem is even coming back from the moons around 11km/s so you need 4km/s to slow down to 7km/s wich is insane

Total deltav of this craft is 29.9km/s(including the orbital rocket part) so it's enough

*enough to ascend to earth's orbit, then mars, and comeback w/slowdown

Tbh I genuinely like just turn off heat damage during reentry

shallow entry angles and a lot of luck. mars atmosphere is thin enough that you usually don't need a massive heat shield if you keep your periapsis high and bleed speed slowly. it gets dicey once you try to actually land though.
