Mission highlights

The STS-84 mission was the sixth Shuttle/Mir docking 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 Russian space station

. The U.S. astronauts launched and landed on a Shuttle and servd as Mir crew members while the Russian Mir crewmembers used their Soyuz vehicle for launch and landing. This series of missions expanded U.S. research on Mir by 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 3318 kilograms (7,314.9 lb) of water and logistics to and from the Mir. During the docked phase, 465 kilograms (1,025.1 lb) of water, 383.2 kilograms (844.8 lb) of U.S. science equipment, 1168.6 kilograms (2,576.3 lb) of Russian logistics along with 178.1 kilograms (392.6 lb) of miscellaneous material were transferred to Mir. Returning to Earth aboard Atlantis were 407.1 kilograms (897.5 lb) of U.S. science material, 531.2 kilograms (1,171.1 lb) of Russian logistics, 14 kilograms (30.9 lb) of ESA material and 170.7 kilograms (376.3 lb) of miscellaneous material.

Sixth Shuttle-Mir docking highlighted by transfer of fourth successive U.S. crew member to the Russian Space Station. U.S. astronaut C. Michael Foale exchanged places with Jerry Linenger, who arrived at Mir 15 January 1997 with the crew of Shuttle Mission STS-81. Linenger spent 123 days on Mir and just over 132 days in space from launch to landing, placing him second behind U.S. astronaut Shannon Lucid

 for 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 at Mir 22 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) with Mir 23 Commander Vasili Tsibliev to attach a monitor to the outside of the station. The Optical Properties Monitor (OPM) was to remain on Mir for 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 aboard Mir at the time included two Mir 22 cosmonauts and a German cosmonaut, and two Mir 23 cosmonauts.

STS-84 docking with Mir occurred 16 May at 10:33 pm EDT above the Adriatic Sea

 and Linenger, followed by a safety briefing. Linenger and Foale officially traded places at 10:15 am EDT.

Transfer of items to and from Mir proceeded smoothly and was completed ahead of schedule. One of 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 (992.1 lb) of water moved to Mir, for a total of about 3400 kilograms (7,495.7 lb) of water, experiment samples, supplies and hardware.

The research program conducted by Foale featured 35 investigations total (33 on Mir, 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 9:04 pm EDT, 21 May. Unlike prior dockings, no flyaround of the station by the orbiter was conducted, but orbiter was stopped three times while backing away to collect data from a European sensor device designed to assist future rendezvous of a proposed European Space Agency

 resupply vehicle with the International Space Station.

Other activities conducted during the mission included investigations using the Biorack facility, located in the SPACEHAB Double Module in Atlantis’s payload bay, a photo survey of Mir during docked operations, environmental air samplings and radiation monitoring.

Orbiter performance was normal from launch to landing.
