BRIGHAM CITY, Utah — America's manned space flight program faces another test today when Morton Thiokol Inc. conducts the second full-scale firing of its redesigned shuttle booster rocket.
The results of the test will help determine if the National Aeronautics and Space Administration can meet its June 2, 1988, timetable for resuming shuttle flights.
The shuttle program was halted and the booster manufacturer launched a redesign program after the explosion that destroyed Challenger and killed its seven crew members on Jan. 28, 1986.
Cold Weather a Factor
A presidential commission found that hot flaming gases leaked from a joint between two segments of one of Challenger's solid fuel boosters, igniting the shuttle's huge external fuel tank. Cold weather was found to be a factor in the joint seal failure.
