Space Shuttle Discovery Launch Delayed Again

During a thorough review of space shuttle Discovery's readiness for flight, NASA managers decided Friday more data and possible testing are required before proceeding to launch. 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. Gerstenmaier chaired Friday's 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."

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 launch of Space Shuttle Discovery was originally slated for February 12th, which was then moved to February 19th due to NASA checking the control valve issue a few weeks ago.

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, Feb. 25. Afterward, the setting of a new target launch date may be considered. Which could likely be in the March time frame if they decide to move forward.
