NASA to delay launch of Discovery again, Orlando Sentinel
“NASA plans to delay the final launch of space shuttle Discovery at least until February, according to a source. The problem remains the cracks discovered in the shuttle’s external fuel tank last month. NASA’s Program Requirements Control Board has reviewed repairs and engineering evaluations associated with cracks on two 21-foot-long, U-shaped aluminum brackets, called stringers, on the tank but decided the analysis and tests required to launch Discovery safely are not complete, the source said.”
