MISSION CONTROL CENTER STS-71 Status Report #5 Thursday, June 29, 1995, 5:30 p.m. CDT Following a successful docking at 8 a.m. today with the Russian Mir Space Station, Atlantis' crew completed a transfer of responsibilities for the station from the three Mir-18 crew members to the two Mir-19 crewmen. Following a transfer of personal gear and a changeout of the individual, custom-made foam seat liners in the Soyuz capsule also docked to Mir, Mir-19 Commander Anatoly Solovyev and Flight Engineer Nikolai Budarin officially assumed duties on the station. Solovyev and Budarin will sleep aboard the Mir tonight while astronaut Norm Thagard and cosmonauts Vladimir Dezhurov and Gennady Strekalov, aboard Mir for the past 105 days, will sleep aboard Atlantis. Commander Hoot Gibson of Atlantis flew the shuttle to a flawless docking with the Mir station today exactly on schedule while the two spacecraft were 216 nautical miles above the Lake Baykal region of the Russian Federation. Mission Specialist Greg Harbaugh then engaged the docking mechanism to firmly latch the spacecraft together. Later, the Spacelab module in Atlantis cargo bay was reactivated by Mission Specialist Bonnie Dunbar in preparation for a variety of medical experiments that will be performed during the next four days. Atlantis and Mir, now the single largest spacecraft ever in orbit with a total mass of almost one-half million pounds, have performed as expected in the nine and a half hours they have so far been attached. No significant problems or surprises have been observed by Mission Control. The crew will begin an eight-hour sleep period at 5:32 p.m. today and awaken at 1:32 a.m. Friday. The spacecraft are in an orbit with a high point of 218 nautical miles and a low point of 209 nautical miles, circling Earth every 92 minutes, 35 seconds. -end-
