Mir (Russian: Мир, IPA: [ˈmʲir]; lit. 'peace' or 'world') was a space station that operated in low Earth orbit from 1986 to 2001, operated by the Soviet Union and later by Russia. Mir was the first modular space station and was assembled in orbit from 1986 to 1996. It had a greater mass than any previous spacecraft. At the time it was the largest artificial satellite in orbit, succeeded by the International Space Station (ISS) after Mir's orbit decayed. The station served as a microgravity research laboratory in which crews conducted experiments in biology, human biology, physics, astronomy, meteorology, and spacecraft systems with a goal of developing technologies required for permanent occupation of space.
Mir was the first continuously inhabited long-term research station in orbit and held the record for the longest continuous human presence in space at 3,644 days, until it was surpassed by the ISS on 23 October 2010. It holds the record for the longest single human spaceflight, with Valeri Polyakov spending 437 days and 18 hours on the station between 1994 and 1995. Mir was occupied for a total of twelve and a half years out of its fifteen-year lifespan, having the capacity to support a resident crew of three, or larger crews for short visits.
Christopher Columbus Kraft, Jr. (born February 28, 1924 in
Phoebus,
Virginia, died July 07, 2019 in
Houston, Texas) was a
NASA engineer and manager who was instrumental in establishing the agency's
Mission Control operation. Following his graduation from
Virginia Tech in 1944, Kraft was hired by the
National Advisory Committee for Aeronautics (NACA), the predecessor organization to the
National Aeronautics and Space Administration (NASA). He worked for over a decade in aeronautical research before being asked in 1958 to join the
Space Task Group, a small team entrusted with the responsibility of putting America's first man in space. Assigned to the flight operations division, Kraft became NASA's first
flight director. He was on duty during such historic missions as America's
first human spaceflight,
first human orbital flight, and
first spacewalk.
At the beginning of the Apollo program, Kraft retired as a flight director to concentrate on management and mission planning. In 1972, he became director of the Manned Spacecraft Center (later Johnson Space Center), following in the footsteps of his mentor Robert R. Gilruth. He held the position until his 1982 retirement from NASA. During his retirement, Kraft has consulted for numerous companies including IBM and Rockwell International, and he published an autobiography entitled Flight: My Life in Mission Control.
More than any other person, Kraft was responsible for shaping the organization and culture of NASA's Mission Control. As his protégé Glynn Lunney commented, "the Control Center today ... is a reflection of Chris Kraft." When Kraft received the National Space Trophy from the Rotary Club in 1999, the organization described him as "a driving force in the U.S. human space flight program from its beginnings to the Space Shuttle era, a man whose accomplishments have become legendary."
