STS-51-F was the 19th flight of NASA's Space Shuttle program and the eighth flight of Space Shuttle Challenger. It launched from Kennedy Space Center, Florida, on July 29, 1985, and landed eight days later on August 6, 1985.
Extravehicular activity (EVA) is any activity done by an astronaut in outer space outside a spacecraft. In the absence of a breathable Earthlike atmosphere, the astronaut is completely reliant on a space suit for environmental support. EVA includes spacewalks and lunar or planetary surface exploration. In a stand-up EVA (SEVA), an astronaut stands through an open hatch but does not fully leave the spacecraft. EVAs have been conducted by the Soviet Union/Russia, the United States, Canada, the European Space Agency and China.
STS-9 was the ninth NASA Space Shuttle mission and the sixth mission of the Space Shuttle Columbia. Launched on November 28, 1983, the ten-day mission carried the first Spacelab laboratory module into orbit.
STS-7 was NASA's seventh Space Shuttle mission, and the second mission for the Space Shuttle Challenger. During the mission, Challenger deployed several satellites into orbit. The shuttle launched from Kennedy Space Center on June 18, 1983, and landed at Edwards Air Force Base on June 24, 1983. STS-7 carried Sally Ride, America's first female astronaut.
The Manned Maneuvering Unit (MMU) is an astronaut propulsion unit that was used by NASA on three Space Shuttle missions in 1984. The MMU allowed the astronauts to perform untethered extravehicular spacewalks at a distance from the shuttle. The MMU was used in practice to retrieve a pair of faulty communications satellites, Westar VI and Palapa B2. Following the third mission the unit was retired from use. A smaller successor, the Simplified Aid For EVA Rescue (SAFER), was first flown in 1994, and is intended for emergency use only.
Franklin Story Musgrave is an American physician and a retired NASA astronaut. He is a public speaker and consultant to both Disney's Imagineering group and Applied Minds in California. In 1996, he became only the second astronaut to fly on six spaceflights, and he is the most formally educated astronaut with six academic degrees. Musgrave is the only astronaut to have flown aboard all five Space Shuttles.
Robert Laurel Crippen is an American retired naval officer and aviator, test pilot, aerospace engineer, and retired astronaut. He traveled into space four times: as pilot of STS-1 in April 1981, the first Space Shuttle mission; and as commander of STS-7 in June 1983, STS-41-C in April 1984, and STS-41-G in October 1984. He was also a part of the Manned Orbiting Laboratory (MOL), Skylab Medical Experiment Altitude Test (SMEAT), ASTP support crew member, and the Approach and Landing Tests (ALT) for the Space Shuttle.
STS-8 was the eighth NASA Space Shuttle mission and the third flight of the Space Shuttle Challenger. It launched on August 30, 1983, and landed on September 5, 1983, conducting the first night launch and night landing of the Space Shuttle program. It also carried the first African-American astronaut, Guion Bluford. The mission successfully achieved all of its planned research objectives, but was marred by the subsequent discovery that a solid-fuel rocket booster had almost malfunctioned catastrophically during the launch.
STS-41-G was the 13th flight of NASA's Space Shuttle program and the sixth flight of Space Shuttle Challenger. Challenger launched on October 5, 1984, and conducted the second shuttle landing at Kennedy Space Center on October 13, 1984. It was the first shuttle mission to carry a crew of seven, including the first crew with two women, the first American Extravehicular activity (EVA) involving a woman (Sullivan), the first Australian-born person to journey into space as well as the first astronaut with a beard and the first Canadian astronaut.
STS-51-D was the 16th flight of NASA's Space Shuttle program, and the fourth flight of Space Shuttle Discovery. The launch of STS-51-D from Kennedy Space Center (KSC), Florida, on April 12, 1985, was delayed by 55 minutes, after a boat strayed into the restricted Solid Rocket Booster (SRB) recovery zone. STS-51-D was the third shuttle mission to be extended.
STS-29 was the 28th NASA Space Shuttle mission, during which Space Shuttle Discovery inserted a Tracking and Data Relay Satellite (TDRS) into Earth orbit. It was the third shuttle mission following the Challenger disaster in 1986, and launched from Kennedy Space Center, Florida, on March 13, 1989. STS-29R was the eighth flight of Discovery and the 28th Space Shuttle mission overall; its planned predecessor, STS-28, was delayed until August 1989.
STS-43, the ninth mission for Space Shuttle Atlantis, was a nine-day mission whose primary goal was launching the TDRS-E satellite (TDRS-5). The flight also tested an advanced heatpipe radiator for potential use on the then-future space station and conducted a variety of medical and materials science investigations.
STS-49 was NASA's maiden flight of the Space Shuttle Endeavour, which launched on May 7, 1992. The primary goal of its nine-day mission was to retrieve an Intelsat VI satellite, Intelsat 603, which failed to leave Low Earth orbit two years before, attach it to a new upper stage, and relaunch it to its intended geosynchronous orbit. After several attempts, the capture was completed with the only three-person extravehicular activity (EVA) in space flight history. It would also stand until STS-102 in 2001 as the longest EVA ever undertaken.
Karol Joseph "Bo" Bobko was an American aerospace engineer, U.S. Air Force officer, test pilot, and a USAF and NASA astronaut. Bobko was the first graduate of the U.S. Air Force Academy to travel in space and the first person to fly on a space shuttle on three different missions: STS-6, STS-51-D, STS-51-J.
William Benjamin Lenoir was an American electrical engineer and NASA astronaut.
Paul Joseph Weitz was an American naval officer and aviator, aeronautical engineer, test pilot, and NASA astronaut, who flew into space twice. He was a member of the three-man crew who flew on Skylab 2, the first crewed Skylab mission. He was also commander of the STS-6 mission, the maiden flight of the Space Shuttle Challenger.
Donald Herod Peterson was a United States Air Force officer and NASA astronaut. Peterson was originally selected for the Air Force Manned Orbiting Laboratory (MOL) program, but, when that was canceled, he became a NASA astronaut in September 1969. He was a mission specialist on STS-6 on board Challenger. During the mission Peterson performed a spacewalk to test the new airlock and space suits. He logged 120 hours in space. Peterson retired from NASA in 1984.
STS-76 was NASA's 76th Space Shuttle mission, and the 16th mission for Atlantis. STS-76 launched on 22 March 1996 at 08:13:04 UTC from Kennedy Space Center, launch pad 39B. STS-76 lasted over 9 days, traveled about 6,100,000 km (3,800,000 mi) while orbiting Earth an estimated 145 times, and landing at 13:28:57 UTC on 31 March 1996 at Edwards Air Force Base, runway 22.
The Extravehicular Mobility Unit (EMU) is an independent anthropomorphic spacesuit that provides environmental protection, mobility, life support, and communications for astronauts performing extravehicular activity (EVA) in Earth orbit. Introduced in 1981, it is a two-piece semi-rigid suit, and is currently one of two types of EVA spacesuits used by crew members on the International Space Station (ISS), the other being the Russian Orlan space suit. It was used by NASA's Space Shuttle astronauts prior to the end of the Shuttle program in 2011.
