NASA delays launch date of space shuttle Discovery

Washington, Feb 21 (ANI): NASA has delayed the launch date of its space shuttle Discovery, after a thorough review of the spacecrafts readiness for flight.

The decision was taken by NASA managers on February 20, after the review indicated that more data and possible testing is required before launching the STS-119 mission to the International Space Station (ISS).

Engineering teams have been working to identify what caused damage to a flow control valve on shuttle Endeavour during its November 2008 flight.

We need to complete more work to have a better understanding before flying, said Bill Gerstenmaier, associate administrator for Space Operations at NASA Headquarters in Washington who chaired Fridays Flight Readiness Review.

We were not driven by schedule pressure and did the right thing. When we fly, we want to do so with full confidence, he added.

The shuttle has three flow control valves that channel gaseous hydrogen from the main engines to the external fuel tank.

Teams also have tried to determine the consequences if a valve piece were to break off and strike part of the shuttle and external fuel tank.

The Space Shuttle Program has been asked to develop a plan to inspect additional valves similar to those installed on Discovery.

This plan will be reviewed during a meeting on Wednesday, February 25. Afterward, the program may consider setting a new target launch date. (ANI)
