重力的

When the spaceship returned to start procedures to return module down to 15 km away from the ground, it was the pneumatic resistance attack it suffered gravity, a drop from supersonic speed reduced to subsonic and stability in the 200 米/秒 about time to slow down on the parachute on.

当飞船启动返回程序，返回舱下降到距地面15公里时，它所受到的气动阻力近似于它所受的重力，下降速度由超音速减到亚音速，并稳定在200米／秒左右，这时再减速就要靠降落伞了。
