NASA flight delayed

NASA yesterday delayed by another two months the first space shuttle flight since the Columbia disaster, saying it needs more time to ensure that the fuel tank does not shed dangerous pieces of ice at lift-off.

Discovery is now scheduled for launch no earlier than July 12. The flight had been targeted for late May.

A large chunk of foam insulation from the external fuel tank punched a hole in Columbia’s wing that led to the shuttle and crew’s demise during re-entry in February 2003.
