On September 12, 1993, the Space Shuttle Discovery launched on mission STS-51. Astronauts Frank L. Culbertson, Jr., William F. Readdy, James H. Newman, Daniel W. Bursch, and Carl E. Walz made up the crew.
Details of the mission, including the scrubbed launch attempts starting in July, are on this page.
The crew deployed two payloads: the Advanced Communications Technology Satellite (ACTS) and the Orbiting and Retrievable Far and Extreme Ultraviolet Spectrograph-Shuttle Pallet Satellite (OERFEUS-SPAS). The mission lasted nine days — a day longer than scheduled because of adverse weather at the Kennedy Space Center landing site.by
