STS-77 Status Report # 21 Mission Control Center Wednesday, May 29, 1996; 6:30 AM CDT The Shuttle Endeavour glided home this morning to a smooth landing at the Kennedy Space Center to wrap up a 10-day, 4.1 million mile mission devoted to technology research. Commander John Casper and Pilot Curt Brown guided Endeavour to a touchdown on Runway 33 at 6:09 AM Central time, wrapping up the fourth Shuttle mission of the year in which the astronauts completed four rendezvous' with a Spartan satellite and an aerodynamically stabilized satellite called PAMS-STU, designed to test new ways to keep a satellite in the correct orientation without the use of propellents. Casper and Brown fired Endeavour's braking rockets at 5:09 AM Central time to enable the Shuttle to drop out of orbit for its hour-long slide back to Earth. Endeavour streaked across the Pacific, the San Francisco Bay Area, the Rocky Mountains and the Gulf Coast before crossing over into Florida to align itself with KSC's Shuttle Landing Facility. This is Endeavour's last flight until December 1997, when it will be launched again on the STS-88 mission, the first launch of U.S. hardware for the assembly of the International Space Station. Endeavour will be ferried to Palmdale, California in August for eight months of major modifications in preparation for Station assembly missions. Endeavour's astronauts will return to Ellington Field at about 4:30 this afternoon following medical exams in Florida and reunions with their families. -end-
