https://www.space.com/china-chang-e-5-moon-sample-return-mission-launch: Vehicles reentering Earth’s atmosphere from the Moon travel much faster than those returning from low-Earth orbit: about 11 kilometers per second versus 8 kilometers per second.
Whereas human-rated vehicles like NASA’s Apollo capsule relied solely on strong heat-shielding, Chang’e-5 will perform a “skip reentry,” bouncing off the atmosphere once to slow down before plummeting to a landing in Inner Mongolia. The landing site is the same used for returning crewed Shenzhou spacecraft.
