STS-74 was NASA's second Space Shuttle mission to rendezvous and dock with the Russian Space Station Mir. During the 8-day flight the Atlantis crew successfully attached a permanent docking module to Mir and transferred over 2,000 pounds of food, water and scientific supplies for use by the cosmonauts. The STS-74 mission was accomplished in 129 orbits of the Earth, traveling 3.4 million miles in 196 hours, 30 minutes, 44 seconds.
STS-83, the Microgravity Science Laboratory (MSL-1) Spacelab mission, was cut short because of problems with one of the Shuttle's three fuel cell power generation units. Mission duration was 95 hours and 12 minutes, traveling 1.5 million miles in 63 orbits of the Earth.
STS-94 was a re-flight of the Microgravity Science Laboratory (MSL-1) Spacelab mission, and focused on materials and combustion science research in microgravity. Mission duration was 376 hours and 45 minutes, traveling 6.3 million miles in 251 orbits of the Earth.
STS-101 will be the third Shuttle mission devoted to International Space Station (ISS) construction. The objectives include transporting and installing over 5,000 pounds of equipment and supplies, and conducting two space walks.
