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 the Russian Federation. 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.
Eugene Francis "Gene" Kranz (born August 17, 1933) is a retired
NASA Flight Director and manager. Kranz served as a Flight Director, the successor to NASA founding Flight Director
Chris Kraft, during the
Gemini and
Apollo programs, and is best known for his role in directing the successful Mission Control team efforts to save the crew of
Apollo 13, which later became the subject story of a major motion picture of the same name. He is also noted for his trademark close-cut
flattop hairstyle, and the wearing of dapper white "mission" vests (
waistcoats), of different styles and materials made by Mrs. Kranz, during missions for which he acted as Flight Director. A personal friend to the American astronauts of his time, Kranz remains a prominent and colorful figure in the history of U.S. manned space exploration, literally, the embodiment of 'NASA tough-and-competent' of the Kranz Dictum. Kranz has been the subject of movies, documentary films, and books and periodical articles. Kranz is the recipient of a
Presidential Medal of Freedom.
