Mission highlights
[edit]The STS-84 mission was the sixth Shuttle/Mirdocking mission and is part of the NASA/Mir program which consisted of nine Shuttle-Mir dockings and seven long duration flights of U.S. astronauts aboard the Russianspace station.The prior Shuttle-Mir missions wereSTS-71,STS-74,STS-76,STS-79andSTS-81.The U.S. astronauts launched and landed on a Shuttle and served asMircrew members while the Russian Mir crewmembers used their Soyuz vehicle for launch and landing. This series of missions expanded U.S. research onMirby providing resupply materials for experiments to be performed aboard the station as well as returning experiment samples and data to Earth.
STS-84 involved the transfer of 3,318 kilograms (7,315 lb) of water and logistics to and from theMir.During the docked phase, 465 kilograms (1,025 lb) of water, 383.2 kilograms (845 lb) of U.S. science equipment, 1,168.6 kilograms (2,576 lb) of Russian logistics along with 178.1 kilograms (393 lb) of miscellaneous material were transferred toMir.Returning to Earth aboardAtlantiswere 407.1 kilograms (898 lb) of U.S. science material, 531.2 kilograms (1,171 lb) of Russian logistics, 14 kilograms (31 lb) ofESAmaterial and 170.7 kilograms (376 lb) of miscellaneous material.
Sixth Shuttle-Mirdocking highlighted by transfer of fourth successive U.S. crew member to the Russian Space Station. U.S. astronautC. Michael Foaleexchanged places withJerry Linenger,who arrived atMir15 January 1997 with the crew of Shuttle Mission STS-81. Linenger spent 123 days onMirand just over 132 days in space from launch to landing, placing him second behind U.S. astronautShannon Lucidfor most time spent on-orbit by an American. Another milestone reached during his stay was one-year anniversary of continuous U.S. presence in space that began with Lucid's arrival atMir22 March 1996.
Other significant events during Linenger's stay included first U.S.-Russian space walk. On 29 April 1997 Linenger participated in five-hour extravehicular activity (EVA) withMir23 CommanderVasily Tsibliyevto attach a monitor to the outside of the station. The Optical Properties Monitor (OPM) was to remain onMirfor nine months to allow study of the effect of the space environment on optical properties, such as mirrors used in telescopes.
On 23 February, a fire broke out on the 11-year-old station. It caused minimal damage but required station's inhabitants to wear protective masks for about 36 hours until cabin air was cleaned. Besides Linenger, crew members aboardMirat the time included twoMir22 cosmonauts and a German cosmonaut, and twoMir23 cosmonauts.
STS-84 docking withMiroccurred on 17 May at 02:33 UTC above theAdriatic Sea.Hatches between two spacecraft opened at 04:25 am, 17 May. Greetings exchanged between STS-84 crew andMir23 Commander Vasily Tsibliyev, Flight EngineerAleksandr Lazutkinand Linenger, followed by a safety briefing. Linenger and Foale officially traded places at 14:15 UTC.
Transfer of items to and fromMirproceeded smoothly and was completed ahead of schedule. One of the first items transferred to station was an Elektron oxygen-generating unit. Altogether about 249 items were moved between the two spacecraft, and about 450 kilograms (990 lb) of water moved toMir,for a total of about 3,400 kilograms (7,500 lb) of water, experiment samples, supplies and hardware.
The research program conducted by Foale featured 35 investigations total (33 onMir,two on STS-84, and another preflight/postflight) in six disciplines: advanced technology, Earth observations and remote sensing, fundamental biology, human life sciences, space station risk mitigation, and microgravity sciences. Twenty-eight of these were conducted during previous missions and were to be continued, repeated or completed during Foale's stay. Seven new experiments were planned in biological and crystal growth studies and materials processing.
Undocking occurred at 01:04 UTC on 22 May. Unlike prior dockings, no flyaround of the station by the orbiter was conducted, but the orbiter was stopped three times while backing away to collect data from a European sensor device designed to assist future rendezvous of a proposedEuropean Space Agencyresupply vehicle with the International Space Station.
Other activities conducted during the mission included investigations using the Biorack facility, located in the SPACEHAB Double Module inAtlantis's payload bay, a photo survey ofMirduring docked operations, environmental air samplings andradiation monitoring.
Orbiter performance was normal from launch to landing. For the mission,Atlantiswas equipped with a 4,187-kilogram (9,231 lb) SpaceHab Double Module, and a 1,922-kilogram (4,237 lb)Orbiter Docking System.
