...microgravity The virtual lack of gravity experienced by astronauts in space. The term is more accurate than ‘zero gravity’ or ‘weightlessness’, both of which imply a complete absence of gravity. The environment of microgravity is excellent for experiments concerning chemicals and materials, as conducted in the Microgravity Science Laboratory . The phenomenon also causes space sickness . https://www.nasa.gov/centers/marshall/news/background/facts/microgravity.html News of NASA's microgravity research programme. http://www.esa.int/esapub/onstation/os1.pdf The...

... An environment, such as a spacecraft, in which gravitational forces exerted on the body are less than normal. Prolonged exposure to microgravity results in effects similar to detraining in athletes (e.g. loss of muscle and bone mass). These changes can present problems when returning to a normal gravity. Regular in-flight exercise, including resistance training and aerobic activities, may counteract some of these...

...International Microgravity Laboratory ( IML ) A Spacelab module dedicated to the operation of a suite of international experiments researching the effects of microgravity on materials processing and life sciences. IML 1 was launched aboard the Discovery space shuttle on 22 January 1992 for an eight-day mission with a crew of six. A second IML was launched aboard the Columbia space shuttle on 8 July 1994 , for a 14-day mission with a seven-person crew. Experiments included the observation of the effect of microgravity on crystal growth and...

...Microgravity Science Laboratory ( MSL ) The laboratory flown on the space shuttle Columbia 1– 17 July 1997 . Its 16 days of scientific experiments were crucial to long-term investigations planned for the International Space Station . Besides experiments in material science , the MSL-1 crew members carried out research on protein crystal growth and on combustion, which may improve fuel efficiency and reduce the pollution of internal combustion engines. On MSL-1 , scientists used Germany's TEMPUS electromagnetic levitation furnace to examine the...

...United States Microgravity Laboratory ( USMG ) One of two NASA scientific laboratories launched aboard its Spacelab module to study the effects of microgravity (weak gravity causing weightlessness in space). Each USMG carried 14 experiments. USMG-1 was launched on the space shuttle Columbia on 25 June 1992 for a 14-day mission, and USMG-2 was launched on 20 October 1995 for a 16-day mission. Among the experiments on both flights were those to grow plants and protein crystals and to study how liquids react under microgravity...
