    Heat shields.

    They retro fire the shuttle engines to slow it down before entering the earth's atmosphere. If they entered the atmosphere at orbital speeds, the shuttle would disintegrate.

    They also do computer controlled and programmed S-turns to bleed off speed.

    Re-entry means to come back into the earth's atmosphere.

    To protect it they use heat shields and they control the decent, both the angle of entry and the speed of entry.
