STS-80 Report # 05 Thursday, November 21, 1996 6 p.m. CST While the astronomy satellite they released Tuesday began its scientific work, Columbia's astronauts turned their attention today to preparations for the major activities still to come during their two remaining weeks in space. Columbia reached a distance of about 32 miles from the ORFEUS-SPAS satellite before firing its engines this afternoon to again begin closing in on the spacecraft. In the early hours of Friday morning, when the shuttle reaches about 17 miles from ORFEUS-SPAS, another engine firing will again separate the shuttle from the satellite. Columbia will then reach a point around 57 miles from ORFEUS-SPAS by Friday evening when the crew releases a second satellite, the Wake Shield Facility (WSF). In preparation for two spacewalks to be performed by Payload Commander Tammy Jernigan and Mission Specialist Tom Jones later in the flight, three spacesuits aboard Columbia were checked out today. Jernigan, Jones and astronaut Story Musgrave inspected the suits, finding everything in excellent condition for the upcoming spacewalks, which will test techniques and equipment that may be used for future construction of the International Space Station. Later this evening, Musgrave is scheduled to perform pre-deploy checkouts of the WSF satellite, a spacecraft that will fly free from the shuttle for three days to investigate the use of space as a vacuum for creating advanced semiconductor materials. The WSF is planned to be released from Columbia at about 7:11 p.m. CST Friday. Other experiments conducted by the crew today included the VIEW-CPL, an investigation of capillary pumped loop equipment in weightlessness designed by University of Maryland students. Such technology may one day be used in cooling systems for future spacecraft, allowing fluids to be pumped without the use of moving parts. Late this afternoon, Commander Ken Cockrell and Pilot Kent Rominger spoke with the Fox News Channel during a 10-minute interview, fielding general questions about their flight and life on the shuttle. Columbia is in a 220 by 216 statute mile orbit. The crew will go to sleep at 2:56 a.m. Friday and awaken at 10:56 a.m. Friday to begin Day 4 of STS-80.
