NASA resumes testing shuttle engines

In a landmark of sorts as NASA attempts to recove from the wide-ranging effects of the Challenger explosion, the agency on June 25 test-fired a space shuttle engine for the first time since the disaster. Conducted at the National Space Technology Laboratories (NSTL) in Bay st. Louis, Mo., the test lasted only 1.5 seconds, primarily as a check of the engine and its components on the test stand in preparation for a 250-second firing expected to take place within the next two weeks. All shuttle engines are ground-tested before they are used in a launching, and NSTL has been conducting such tests since 1975, six years before the shuttle first blasted off. Although there had been no layoffs since the accident, says an NSTL official, the brief firing symbolized a "return to normalcy." The test itself, says the official, went "just fine."
