Ulf Dietrich Merbold (German: [ʊlf ˈdiːtrɪç ˈmɛrbɔlt]; born 20 June 1941) is a German physicist and astronaut who flew to space three times, becoming the first West German citizen in space and the first non-American to fly on a NASA spacecraft. Merbold flew on two Space Shuttle missions and on a Russian mission to the space station Mir, spending a total of 49 days in space. Merbold's father, a Wehrmacht soldier, was imprisoned in NKVD special camp Nr. 2 by the Red Army in 1945 and died there in 1948, and Merbold was brought up in the town of Greiz in East Germany by his mother and grandparents. As he was not allowed to attend university in East Germany, he left for West Berlin in 1960, plan…

Effects of Gravity, Microgravity or Microgravity Simulation on Early Mammalian Development.. Plant and animal life forms evolved mechanisms for sensing and responding to gravity on Earth where homeostatic needs require responses. The lack of gravity, such as in the International Space Station (ISS), causes acute, intra-generational changes in the quality of life. These include maintaining calcium levels in bone, maintaining muscle tone, and disturbances in the vestibular apparatus in the ears. These problems decrease work efficiency and quality of life of humans not only during microgravity exposures but also after return to higher gravity on Earth or destinations such as Mars or the Moon.…

The Vostok programme ( VOST-ok, vost-OK; Russian: Восток, IPA: [vɐˈstok] , lit. 'East') was a Soviet human spaceflight project to put the first Soviet cosmonauts into low Earth orbit and return them safely. Competing with the United States Project Mercury, it succeeded in placing the first human into space, Yuri Gagarin, in a single orbit in Vostok 1 on April 12, 1961. The Vostok capsule was developed from the Zenit spy satellite project, and its launch vehicle was adapted from the existing R-7 Semyorka intercontinental ballistic missile (ICBM) design. The name "Vostok" was treated as classified information until Gagarin's flight was first publicly disclosed to the world press. The programm…
