All NASA shuttles are protected upon atmospheric reentry by a ceramics-based heat shield, which is able to handle the thousands of degrees that heat up the spacecraft' underbellies. For all their resilience, these heat shields are extremely sensitive, and even minor impacts can cause very dangerous dents. After ... |
