Heat Shield

The ablative or reusable shield that protects a spacecraft from the searing heat of atmospheric entry, where air violently compressed ahead of the vehicle's bow shock can reach thousands of degrees (the heating is dominated by shock compression, not friction). Ablative shields char and carry heat away as they erode.

Highlights

  • Survives thousands of degrees at atmospheric entry
