Shuttle Discovery's launch delayed a few more days

Work to repair the shuttle Discovery's external tank is going well, but more time is needed to complete an engineering review and to develop the necessary flight rationale, the justification for launching with a repaired tank after unexpected damage. As a result, NASA announced Thursday, the flight will remain on hold until at least Dec. 3, four days after the opening of a short end-of-year launch window. If Discovery is eventually cleared for launch, countdown clocks would begin ticking around 1 a.m. on Nov. 30, setting up a launch attempt at 2:51:59 a.m. EST on Dec. 3. More
