[107] => [108] => The rendezvous sequence began at 15:32:19 EDT with a lift-off in-plane with Mir's orbit, at the opening of the 10 minute 19 second launch window. Ascent was nominal with no OMS 1 burn required. The OMS 2 burn, initiated at 42 minutes 58 seconds Mission Elapsed Time, adjusted the orbit to 160 x 85.3 nautical miles. It was the lowest ever perigee altitude flown by an orbiter.{{cite report|title=STS-71 Space Shuttle Mission Report|page=3|publisher=NASA|date=1995}} This facilitated a very rapid initial catch up rate with Mir of about 880 nautical miles per orbit.{{cite web|url=https://science.ksc.nasa.gov/shuttle/missions/sts-71/sts-71-day-01-highlights.html|title=STS-71 Day 1 Highlights|publisher=NASA|date=1995}} Almost three hours later the orbit was raised to more typical values of 210 x 159 nautical miles by the OMS 3 burn. [109] => [110] => Docking occurred at 9 am EDT, June 29, using R-Bar or Earth radius vector approach, with ''Atlantis'' closing in on Mir from directly below. R-bar approach allows natural forces to brake the orbiter's approach more than would occur along standard approach directly in front of the space station; also, an R-bar approach minimizes the number of orbiter jet firings needed for approach. The manual phase of the docking began with ''Atlantis'' about a half-mile (800 m) below Mir, with Gibson at the controls on aft flight deck. Stationkeeping was performed when the orbiter was about {{convert|75|m}} from ''Mir'', pending approval from Russian and U.S. flight directors to proceed. Gibson then maneuvered the orbiter to a point about {{convert|10|m}} from ''Mir'' before beginning the final approach to station. Closing rate was close to the targeted 0.1 foot per second (30 mm/s), being approximately 0.107 foot per second (33 mm/s) at contact. Interface contact was nearly flawless: less than {{convert|25|mm}} lateral misalignment and an angular misalignment of less than 0.5 degrees per axis. No braking jet firings had been required.{{cite report|title=STS-71 Space Shuttle Mission Report|page=5|publisher=NASA|date=1995}} Docking occurred about 216 nautical miles ({{convert|400|km}}) above [[Lake Baikal]] region of the Russian Federation. The Orbiter Docking System (ODS) with Androgynous Peripheral Docking System served as the actual connection point to a similar interface on the docking port on Mir's [[Kristall]] module. ODS, located in the forward payload bay of ''Atlantis'', performed flawlessly during the docking sequence. [111] => [112] => When linked, ''Atlantis'' and Mir formed the largest spacecraft ever in orbit, with a total mass of about 225 [[tonne|metric tons]] (almost one-half million pounds), orbiting some 218 nautical miles ({{convert|404|km}}) above the Earth. After hatches on each side opened, STS-71 crew passed into ''Mir'' for a welcoming ceremony. On the same day, the Mir 18 crew officially transferred responsibility for the station to the Mir 19 crew, and the two crews switched spacecraft. [113] => [114] => [[File:S71e0003.jpg|right|thumb|Vladimir Dezhurov and "Hoot" Gibson shake hands in orbit, a homage to the Apollo-Soyuz Test Project (ASTP). Later that day, President Bill Clinton announced that this handshake was a major breakthrough towards the end of the Cold War.]] [115] => For the next five days, about 100 hours in total, joint U.S.-Russian operations were conducted, including biomedical investigations, and transfer of equipment to and from ''Mir''. Fifteen separate biomedical and scientific investigations were conducted, using the Spacelab module installed in the aft portion of ''Atlantis''{{'}}s payload bay, and covering seven different disciplines: cardiovascular and pulmonary functions; human metabolism; neuroscience; hygiene, sanitation and radiation; behavioral performance and biology; fundamental biology; and microgravity research. The Mir 18 crew served as test subjects for investigations. Three Mir 18 crew members also carried out an intensive programme of exercise and other measures to prepare for re-entry into gravity environment after more than three months in space. [116] => [117] => Numerous medical samples as well as disks and cassettes were transferred to ''Atlantis'' from ''Mir'', including more than 100 urine and saliva samples, about 30 blood samples, 20 surface samples, 12 air samples, several water samples and numerous breath samples taken from ''Mir'' 18 crew members. Also moved was a broken Salyut-5 computer. Transferred to ''Mir'' were more than {{convert|450|kg}} of water generated by the orbiter for waste system flushing and electrolysis; specially designed spacewalking tools for use by the ''Mir'' 19 crew during a spacewalk to repair a jammed solar array on the Spektr module; and transfer of oxygen and nitrogen from Shuttle's environmental control system to raise air pressure on the station, to improve ''Mir''{{'}}s consumables margin. [118] => [119] => [[File:STS-71 chute deploy.jpg|right|thumb|''Atlantis'' lands at the Kennedy Space Center at the end of STS-71.]] [120] => The spacecraft undocked on July 4, following a farewell ceremony, with the Mir hatch closing at 3:32 pm EDT. July 3 and hatch on Orbiter Docking System shut 16 minutes later. Gibson compared separation sequence to a "cosmic" ballet: Prior to the ''Mir''-''Atlantis'' undocking, the ''Mir'' 19 crew temporarily abandoned station, flying away from it in their Soyuz spacecraft so they could record images of ''Atlantis'' and ''Mir'' separating. Soyuz unlatched at 6:55 am EDT, and Gibson undocked ''Atlantis'' from ''Mir'' at 7:10 am EDT. Whilst both spacecraft were undocked from ''Mir'', the station suffered a computer malfunction and started to drift in attitude. The ''Mir'' 19 crew performed a hasty re-docking, monitored by ''Atlantis''. They subsequently replaced computer hardware allowing them to regain attitude control. [121] => [122] => The returning crew of eight equaled the largest crew ([[STS-61-A]], October 1985) in Shuttle history. To ease their re-entry into gravity environment after more than 100 days in space, ''Mir'' 18 crew members Thagard, Dezhurov and Strekalov lay supine in custom-made recumbent seats installed prior to landing in the orbiter middeck. [123] => [124] => Inflight problems included a glitch with General Purpose Computer 4 (GPC 4), which was declared failed when it did not synchronize with GPC 1; subsequent troubleshooting indicated it was an isolated event, and GPC 4 operated satisfactorily for the remainder of mission. [125] => [126] => During the SAREX portion of the flight, the crew contacted several schools. One was Redlands High School in Redlands, California. Charlie Precourt was able to contact students, former students and technicians that built the communications package. A cross polarized, dual band yagi antenna array and automatic rotor was installed on the roof of the electronics classroom. A dual band radio was installed inside the radio room of the classroom. The contact window lasted about 10 minutes, during which time, about twelve people were able to ask questions. While most were basic or technical questions, one was peculiar. "What would happen of you sneezed inside your helmet?" Precourt answered that you'd probably, "spray your face shield a little bit.." and carry on.
