MISSION CONTROL CENTER STS-71 Status Report #21 Friday, July 7, 1995, 3:30 p.m. CDT Commander "Hoot" Gibson and Pilot Charlie Precourt guided Atlantis to a smooth touchdown at the Kennedy Space Center at 9:55 AM Central time this morning to wrap up the first mission to linkup a Shuttle with the Russian Space Station Mir. After firing Atlantis' braking rockets at 8:45 AM, Gibson and Precourt brought Atlantis home to runway 15 at the Kennedy Space Center's Shuttle Landing Facility to complete the 4.1 million mile mission, the first of seven planned docking flights to the Mir as part of the Phase One program leading to the development and construction of the International Space Station. About an hour after landing, Mir 18 cosmonauts Vladimir Dezhurov, Gennady Strekalov and U.S. astronaut Norm Thagard were brought out of the Shuttle into the Crew Transport Vehicle alongside Atlantis for their ride to the Operations and Checkout Building at KSC for initial postflight medical testing. The Mir 18 crewmembers spent 115 days in space following their launch on a Russian Soyuz rocket from the Baikonur Cosmodrome on March 14th. Dezhurov, Strekalov and Thagard will be flown back to Ellington Field in Houston in an Air Force C-9 Medevac plane for several weeks of medical tests and reorientation to a gravity environment after almost four months of weightlessness. They are expected to arrive in Houston about 9 1/2 hours after landing. The rest of the STS-71 crew is scheduled to Houston around 9 PM. Atlantis was towed this afternoon to the Orbiter Processing Facility at KSC to begin a maintenance period leading to its next launch in late October on STS-74, the second Shuttle-Mir docking mission, in which a Russian-built Docking Module will be permanently mated to the Kristall science module's docking mechanism on the Mir. That will enable Atlantis to linkup to Mir on future flights with enough clearance to avoid interference with the Russian Space Station's solar arrays.
