STS-80 Report # 04 November 21, 1996 6 a.m. CST While Columbia's astronauts sleep, scientists on the ground are completing their setup of the ORFEUS-SPAS instruments and preparing to begin observations with the free-flying spacecraft. Columbia is about 33 miles from the Orbiting Retrievable Far and Extreme Ultraviolet Spectrometer (ORFEUS), mounted on the reusable Shuttle Pallet Satellite (SPAS) and closing about half a mile each time it circles the Earth following a pre-bedtime maneuver. The next maneuver, scheduled for 2:11 p.m. CST, will move Columbia to within 20 miles of ORFEUS-SPAS in hopes that radar data will provide a more precise fix on the satellite to compute the next maneuver. The two spacecraft will continue their orbital dance for 14 days before the satellite and its cargo of information about the origin of stars is berthed safely in the cargo bay and ready for return to Earth. Commander Ken Cockrell, Pilot Kent Rominger and Mission Specialists Tammy Jernigan, Tom Jones and Story Musgrave went to bed just before 3 a.m. CST and will awaken at 10:56 a.m. The coming day's activities will focus on checking out the Wake Shield Facility and preparing Columbia's airlock and the space suits that will be worn by Jernigan and Jones on their two space walks Nov. 28 and 30. The Wake Shield is scheduled to be deployed Friday evening and retrieved late Monday night. The saucer-shaped spacecraft will fly free of the orbiter and ram its way through the extremely rare atmosphere creating an ultravacuum that promotes the growth of near- perfect thin film semiconductor materials. Columbia is orbiting the Earth every 90 minutes at an altitude of 218 statute miles with all systems operating normally. -- end -- NASA Johnson Space Center Mission Status Reports and other information are available automatically by sending an Internet electronic mail message to jscnews-request@listserver.jsc.nasa.gov.
