An astronaut is to make unprecedented repairs to the space shuttle Discovery, the US space agency Nasa has announced. The astronaut will remove strips that are sticking out between heat shield tiles on Discovery's belly.

Nasa is concerned the dangling material - called gap fillers - could cause part of the shuttle to overheat as it re-enters the atmosphere. The type of repairs being planned have never been conducted by astronauts on a spacewalk before.

The space station's robotic arm will manoeuvre an astronaut into position so he can fix the problem. This task will be added to the third planned spacewalk of the mission - which may be delayed to give the crew time to prepare.
