MISSION CONTROL CENTER STS-71 Status Report #14 Tuesday, July 4, 1995, 5 a.m. CDT Atlantis was scheduled to separate from Russia's Mir space station at 6:10 this morning, concluding the historic mission that saw an American and Russian spacecraft commander shake hands in orbit for the first time in 20 years. As the Atlantis crew was awakened to a celebration of America's 219th birthday and the sounds of "America the Beautiful," their colleagues on board the Mir space station were well into procedures to deactivate some of the station's systems. Mir will be temporarily uninhabited following the undocking of the Soyuz capsule from the station. With Mir 19 Commander Anatoly Solovyev at the controls, the Soyuz was to undock from Mir at 5:55 AM, and move to a stationkeeping position to photograph the linked Atlantis/Mir space complex. Mir 19 Commander Anatoly Solovyev will redock his Soyuz capsule to the Mir space station about 6:43 a.m. to begin a two-month stay. Before leaving the area, the STS-71 and Mir 18 crews on board Atlantis, will fly around Mir conducting a photo survey of the space station. With the five-days of docked operations behind them, the STS-71 and Mir 18 crew members will settle into a routine of continuing medical and scientific investigations on board Atlantis. The joint U.S./Russian investigations are studying how the human body responds to an extended stay in microgravity. The Mir 18 crew members -- Commander Vladimir Dezhurov, Flight Engineer Gennady Strekalov and Cosmonaut Researcher Norm Thagard -- are beginning their 112th day in orbit. Flying free of Mir for the first time in five days, Atlantis is functioning virtually trouble- free on its 14th journey in space. end
