A segment of a Space Shuttle solid rocket motor was test fired at Morton Thiokol's Wasatch facility in than in a test of the solid rocket motor nozzle joint. The overall test objective was to evaluate performance of the redesigned solid rocket motor case-to-nozzle joint that had an insulation adhesive defect and damaged o-ring in order to determine the fail-safe performance of the redesigned joint. The redesigned case-to-nozzle joint included 100 added radial bolts, adhesively bonded insulation surfaces, and an added "wiper" o-ring designed to keep the adhesive on the insulation surfaces during assembly. The test was part of the Shuttle motor redesign program. (NASA Release 88-23)
NASA announced that it would lease to the U.S. Government unassigned space aboard a commercially developed space facility. The leasing agreement would apply for five years beginning at the end of fiscal year 1993. At least 30 percent of the facility would be available for commercial use.
The facility would be deployed, checked out, and serviced periodically on orbit by Space Shuttle crews. It would provide a crew-tended, shirtsleeve workspace and would also be able to operate in an untended, free-flying mode, providing a microgravity environment for periods of four to six months. NASA would initiate an open competition to be managed by the Marshall Space Flight Center, Huntsville, Alabama. (NASA Release 88-25)
