In preparation for more x-ray type scans of space shuttle Discovery’s external fuel tank, technicians remove foam insulation and sensors from around the tank’s intertank area inside the Vehicle Assembly Building (VAB) at NASA’s Kennedy Space Center in Florida on Dec. 23. Next week, crews will scan below the external tank’s foam insulation around the entire intertank section to look for any issues, such as cracks. They also will reapply foam where sensors are removed from the tank’s aluminum skin following an instrumented tanking test on Dec. 17.

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.
