WebDec 8, 2024 · Reentering the atmosphere from Earth orbit is a relatively easy thing: a matter of firing retro-rockets and slowing the spacecraft’s velocity below the 28,160 km/h (17,500 mph) speed necessary ... WebIt's reentry speed is much faster, a little over 11,000 meter/second! The higher speed comes from the fact that the spacecraft must fly fast enough to completely leave Earth orbit. That makes the reentry heating problem even more difficult. NASA is now working on developing new materials that can survive such speeds for the new Orion spacecraft.
