Safety Concerns: Space Shuttle Thermal Protection

Columbia reaches orbit. But astronaut Bob Crippen discovers that the shuttle has been damaged – can he and John Young make it home safely?

Parts of the heatshield to protect the shuttle from searing temperatures on re-entry to Earth have fallen off during the journey into space. This new heatshield has never been tested before in orbit. Could more tiles be missing?

Some scenes in this series use recreated sound effects.

13 Minutes Presents: The Space Shuttle is a BBC Audio Science Unit production for BBC World Service.

Hosted by space scientist Maggie Aderin-Pocock.

Theme music by Hans Zimmer and Christian Lundberg, and produced by Russell Emanuel, for Bleeding Fingers Music.
