ENGINE TEST SCHEDULED AT MARSHALL CENTER FRIDAY

The Marshall Space Flight Center in Huntsville, Ala. is scheduled to test an instrumented modified Space Shuttle Main Engine for 7.5 seconds Friday at approximately 11:00 a.m. in the Advanced Engine Test Facility

The test will help engineers characterize the performance of the main engine under conditions that might expand operational capabilities for future reusable launch vehicles.

Also, the test will evaluate an abbreviated cooling period for engine systems during the loading of liquid oxygen and liquid hydrogen.

The engine will be operated at 25 percent power level for 5 of the 7.5 second test run. The test will be the sixty-second firing of a modified Space Shuttle engine in the former Saturn V engine test facility.
