How does it deal with the problems of being heated up on re-entry into the atmosphere?
The underside of the space shuttle is covered in thousands of insulating tiles. These protect it from the heat caused by contact with the atmosphere as it descends. The temperature on the outside of the shuttle can reach 1,300 °C, but the insulation keeps the inside cool. |

It must be remembered that the process of going into space is still an adventure and astronauts are true explorers. Unfortunately, as with all exploration, it is a dangerous activity and things can go wrong. Two space shuttles have been destroyed in accidents. The shuttle Challenger exploded shortly after launch in 1986 and the shuttle Columbia broke up when re-entering the atmosphere on 1st February 2003. It is thought that the insulating tiles might have been damaged. Sadly, in both cases all the members of the crew were killed. |
