Space Shuttle launch delayed

A Mission Management meeting looks likely to decide fate of Shuttle Discovery launch.

The first space shuttle scheduled to launch on Independence Day, following unfavourable weather conditions, was thrown into doubt when an inspection revealed a crack in the foam insulation of the orbiter's external fuel tank.

In a statement NASA said: "During a routine inspection overnight after the draining of the tank, a crack was discovered in the foam near a bracket on the external fuel tank that holds the liquid oxygen feedline in place.

"The mission management team is meeting to discuss this and to determine what, if any, impact this will have on our launch date."

Commenting on Sunday after the launch postponement, Mission Management Team Chairman John Shannon said: "...the team really performed in exemplary fashion and got the vehicle ready to go and the crew ready to go. It was that one thing that we really don't control - the weather - it's what kept us from launching."

An update was expected today on the progress at the pad to confirm the readiness of the vehicle for flight, but it only served to confirm an unexpected problem with the foam insulation on the huge external fuel tank.

A piece of foam which broke away during the launch of Columbia and damaged the wing caused the loss of the Space Shuttle Columbia in 2003.

Among the STS-121 Discovery seven-man mission crew is British astronaut Piers Sellers.

The crew is expected to spend two weeks in orbit with the primary goal of testing new systems for inspecting the shuttle's heat shield.

One crew member, German Thomas Reiter, is to spend six months on the International Space Station.
