Ronald McNair
Ronald Erwin McNair (October 21, 1950 – January 28, 1986) was an American NASA astronaut and physicist. He died during the launch of the Space Shuttle ''Challenger'' on mission STS-51-L, in which he was serving as one of three mission specialists in a crew of seven. Prior to the ''Challenger'' disaster, he flew as a mission specialist on STS-41-B aboard ''Challenger'' from February 3 to 11, 1984, becoming the second African American and the first Baháʼí to fly in space. Background McNair was born October 21, 1950, in Lake City, South Carolina, to Pearl M. and Carl C. McNair. He had two brothers, Carl and Eric A. McNair. In the summer of 1959, he refused to leave the segregated Lake City Public Library without being allowed to check out his books. After the police and his mother were called, he was allowed to borrow books from the library; the building that housed the library at the time is now named after him. A children's book, ''Ron's Big Mission'', offers a fic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Manned Maneuvering Unit
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. Overview The unit featured redundancy to protect against failure of individual systems. It was designed to fit over the life-support system backpack of the Space Shuttle Extravehicular Mobility Unit (EMU). When carried into space, the MMU was stowed in a support station attached to the wall of the payload bay near the airlock hatch. Two MMUs were carried on a mission, with the second unit mounted across from the first on the opposite payload bay w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
STS-9
STS-9 (also referred to Spacelab 1) was the ninth NASA Space Shuttle mission and the sixth mission of the Space Shuttle ''Columbia''. Launched on 28 November 1983, the ten-day mission carried the first Spacelab laboratory module into orbit. STS-9 was also the last time the original STS numbering system was used until STS-26, which was designated in the aftermath of the 1986 ''Challenger'' disaster of STS-51-L. Under the new system, STS-9 would have been designated as STS-41-A. STS-9's originally planned successor, STS-10, was canceled due to payload issues; it was instead followed by STS-41-B. After this mission, ''Columbia'' was taken out of service for renovations, and did not fly again until STS-61-C in early January 1986. STS-9 sent the first non-U.S. citizen into space on the Shuttle, Ulf Merbold, becoming the first ESA and first West German citizen to go into space.

Space Shuttle Challenger
Space Shuttle ''Challenger'' (OV-099) was a Space Shuttle orbiter manufactured by Rockwell International and operated by NASA. Named after the commanding ship of a nineteenth-century scientific expedition that traveled the world, ''Challenger'' was the second Space Shuttle orbiter to fly into space after '' Columbia'', and launched on its maiden flight in April 1983. It was destroyed in January 1986 soon after launch in an accident that killed all seven crewmembers aboard. Initially manufactured as a test article not intended for spaceflight, it was utilized for ground testing of the Space Shuttle orbiter's structural design. However, after NASA found that their original plan to upgrade ''Enterprise'' for spaceflight would be more expensive than upgrading ''Challenger'', the orbiter was pressed into operational service in the Space Shuttle program. Lessons learned from the first orbital flights of ''Columbia'' led to ''Challenger''s design possessing fewer thermal protectio ...

Extravehicular Mobility Unit
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. Suit components The EMU, like the Apollo/Skylab A7L spacesuit, was the result of 21 years of research and development. It consists of a Hard Upper Torso (HUT) assembly, a Primary Life Support System (PLSS) which incorporates the life support and electrical systems, arm sections, gloves, an Apollo-style "bubble" helmet, the Extravehicular Visor Assembly (EVVA), and a soft Lower Torso Assembly (LTA), incorporating the Body Seal Closure (BS ...

Shuttle Landing Facility
The Shuttle Landing Facility (SLF) also known as Launch and Landing Facility (LLF) is an airport located on Merritt Island in Brevard County, Florida, United States. It is a part of the Kennedy Space Center and was used by Space Shuttle for landing until July 2011. It was also used for takeoffs and landings for NASA training jets such as the Shuttle Carrier Aircraft and for civilian aircraft. Starting in 2015, Space Florida manages and operates the facility under a 30-year lease from NASA. In addition to ongoing use by NASA, private companies have been utilizing the SLF since the 2011 end of the Space Shuttle program. Facilities The Shuttle Landing Facility covers and has a single runway, 15/33. It is one of the longest runways in the world, at , and is wide. (Despite its length, astronaut Jack R. Lousma stated that he would have preferred the runway to be "half as wide and twice as long") Additionally, the SLF has of paved overruns at each end. The Mate-Demate Device ...

STS-41-C
STS-41-C (formerly STS-13) was NASA's eleventh Space Shuttle mission, and the fifth mission of Space Shuttle ''Challenger''. The launch, which took place on April 6, 1984, marked the first direct ascent trajectory for a Space Shuttle mission. During the mission, ''Challenger''s crew captured and repaired the malfunctioning Solar Maximum Mission ("Solar Max") satellite, and deployed the Long Duration Exposure Facility (LDEF) experimental apparatus. STS-41-C was extended one day due to problems capturing the Solar Max satellite, and the landing on April 13, 1984, took place at Edwards Air Force Base, instead of at Kennedy Space Center as had been planned. The flight was originally numbered STS-13.James D. A. van Hoften NASA Johnson Space Center Oral History Project. December 5, 2007, Retri ...

Extravehicular Activity
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 (commonly known from 1969 to 1972 as ''moonwalks''). In a stand-up EVA (SEVA), an astronaut stands through an open hatch but does not fully leave the spacecraft. EVA has been conducted by the Soviet Union/Russia, the United States, Canada, the European Space Agency and China. On March 18, 1965, Alexei Leonov became the first human to perform a spacewalk, exiting the Voskhod 2 capsule for 12 minutes and 9 seconds. On July 20, 1969, Neil Armstrong became the first human to perform a moonwalk, outside his lunar lander on Apollo 11 for 2 hours and 31 minutes. On the last three Moon missions, astronauts also performed deep-space EVAs on the return to Earth, to retrieve film ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
