MISSION CONTROL CENTER STS-71 Status Report #20 Friday, July 7, 1995 6:30 a.m. CDT The crew on board Atlantis is preparing to end its historic mission with a 9:55 a.m. central time landing today at the Kennedy Space Center. With weather conditions in Florida expected to be acceptable at landing time, Commander Hoot Gibson transitioned to the deorbit activities timeline shortly before 5 a.m. central with work to configure the crew cabin for reentry well under way. On board, the crew members have closed and secured the airlock connecting the crew compartment to the orbiter docking mechanism and Spacelab module housed in Atlantis' payload bay. Deactivation of the Spacelab module is complete, as is installation of seats on the flight deck that will be occupied by Mission Specialists Ellen Baker and Greg Harbaugh on reentry. There are two opportunities for a landing at KSC this morning. The first opportunity begins with a deorbit burn at 8:45 a.m., with Atlantis touching down at 9:55 a.m. The second opportunity comes one orbit later with a 10:22 a.m. engine firing resulting in an 11:31 a.m. landing. The eight astronauts and cosmonauts began what should be their final day on orbit at 1:32 a.m. with a wake-up call from Mission Control. In recognition of their journey -- which began March 14 in Kazakhastan, the crew awakened this morning to Supertramp's "Take the Long Way Home." All systems on board Atlantis continue in excellent shape as the orbiter circles the Earth every 92 minues in a 216 by 208 nautical mile orbit. -end-
