Backscatter Scans of Tank Continue

NASA space shuttle managers met Thursday at a Program Requirements Control Board (PRCB) to review repairs and engineering evaluations associated with shuttle Discovery and cracks on two 21-foot-long, U-shaped aluminum brackets, called stringers, on the shuttle's external tank. NASA will continue to review and analyze the data before setting a launch date. NASA managers are meeting daily to assess the data and progress being made.

Technicians at Kennedy’s Launch Pad 39A will continue to collect data on the stringer repair by performing backscatter scans, which bounces radiation off space shuttle Discovery’s external fuel tank, through the weekend.

At NASA's Johnson Space Center, the STS-133 crew will review rendezvous procedures today.
