Shuttle to be repaired in space!

Astronaut Stephen Robinson will make a space walk underneath the Shuttle Discovery to 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.

Nasa confirmed that debris did indeed strike the shuttle during launch but Nasa officials say this is not related to damage from foam debris. Instead, the fabric could have been shaken loose by the vibrations during launch.

The International Space Station’s Canadarm2 robotic arm will position Discovery mission specialist Robinson underneath the shuttle so he can pull the gap fillers out.

This will be the first time that a space walk has been made underneath an orbiting shuttle.

Space Shuttles Grounded

NASA has said it is grounding the space shuttle fleet as engineers investigate debris which fell from Discovery’s external fuel tank during launch.
A spokesman for the US space agency said big chunks of foam broke off the tank after Tuesday’s lift-off but are not thought to have damaged the craft.

The Columbia shuttle was destroyed in 2003 after a similar incident.

If the shuttle is damaged, its crew could wait in the International Space Station until a rescue craft arrives.

Discovery is taking parts and supplies to the ISS.

It is the first orbiter mission by the US space agency since the loss of the Columbia and its crew.

It is due to return to Earth in 10 days’ time.
