The Space Shuttle Discovery, seen at the Kennedy Space Center in Cape Canaveral, Fla., is scheduled to launch Monday on a mission to the International Space Station.
Cape Canaveral, FL (AP) - NASA has found a fourth crack in the
fuel tank for space shuttle Discovery.
Discovery's final mission remains on hold as engineers and
technicians work to fix all the cracks as well as a hydrogen gas
NASA spokesman Allard Beutel said Monday the repairs need to be
made before a new launch date is picked. The launch window opens
Nov. 30 and closes Dec. 6.
NASA first discovered a long crack in the insulating foam of the
fuel tank, after the countdown was halted Nov. 5 by the gas leak.
Last week, two cracks were found on the exterior of the tankf. Then
another crack popped up, then another.
The cracks are in the tank's central, ribbed section, which
holds instruments, not fuel.
