At NASA's Kennedy Space Center in Florida, technicians in the Vehicle Assembly Building make additional imaging scans of space shuttle Discovery’s external fuel tank. On Dec. 29, technicians scanned below the external tank’s foam insulation around the entire intertank section to look for any issues, such as cracks.

Workers used computed radiography scanners that work like an X-ray machine by transmitting radiation through the tank's foam and metal skin. The scans will help verify repairs associated with cracks on the tops of two 21-foot-long, U-shaped aluminum brackets called stringers, which line the intertank, and will help engineers determine what caused the cracks during Discovery’s launch attempt on Nov. 5. Managers and engineers will review the test data to determine the next course of action. Discovery’s next launch opportunity for its STS-133 mission to the International Space Station is no earlier than Feb. 3.
