CAPE CANAVERAL, Fla. – On Launch Pad 39A at NASA's Kennedy Space Center in Florida, technicians install three gaseous hydrogen flow control valves on space shuttle Discovery. The valves were retested after installation. Part of the main propulsion system, the valves channel gaseous hydrogen from the main engines to the external tank. NASA and contractor teams have worked to identify what caused damage to a flow control valve on shuttle Endeavour during its November 2008 flight. Space Shuttle Program managers decided to replace Discovery's valves with others that have undergone a detailed eddy current inspection. Program managers will review the testing and determine whether to meet on March 6 for the Flight Readiness Review for the STS-119 mission. Launch of Discovery tentatively is targeted for March 12.
