The incidence and clinical significance of cardiac arrhythmias during long-term exposure to microgravity experienced on the International Space Station (ISS) or during a prolonged (that is, up to 3 years) sojourn to Mars or on the Moon are a concern for the National Aeronautics and Space Administration (NASA).
An experiment conducted aboard the International Space Station in 2003 (Miscible Fluids in Microgravity) was mounted to prove one of Korteweg's theories.
Dieter Langbein, Dr. phil. nat., was a German physicist, whose fields of research included solid state physics, fluid physics and microgravity.
During the mission the crew successfully deployed the Galileo spacecraft, starting its journey to explore Jupiter, operated the Shuttle Solar Backscatter Ultraviolet Instrument (SSBUV) to map atmospheric ozone, and performed numerous secondary experiments involving radiation measurements, polymer morphology, lightning research, microgravity effects on plants, and a student experiment on ice crystal growth in space.
The 2011 winners included "Siphons in Space", proposed by a science club not affiliated with the local school in central New York state, and "Wheat Fertilization in Microgravity", proposed by a team from Licking Heights High School in central Ohio.
EXA had tested microgravity via parabolic flight with the Ecuadorian Air Force and Space Adventures.
The Express is a 745 kg (1,642 lb) satellite for microgravity experiments and testing of re-entry technologies.
Two experiments, originally designed by the winners of the international YouTube Space Lab competition, would examine how Bacillus subtilis and the jumping spider would react to microgravity.
Following candidature by the Italian Space Agency, Urbani was selected by the National Aeronautics and Space Administration (NASA) in May 1995 as an alternate Payload Specialist for the Life and Microgravity Spacelab (LMS) mission, STS-78, and began training for the flight duties of a Payload Specialist Astronaut at the Johnson Space Center in Houston.
During the mission crew members successfully deployed the Galileo spacecraft on its journey to explore Jupiter, operated the Shuttle Solar Backscatter Ultraviolet Instrument (SSBUV) to map atmospheric ozone, and performed numerous secondary experiments involving radiation measurements, polymer morphology, lightning research, microgravity effects on plants, and a student experiment on ice crystal growth in space.
With an "open architecture" design and explicit plans for multi-purpose use, the aircraft could also operate as a zero-g aircraft for passenger training or microgravity science flights, handle missions in high-altitude testing more generally, or be used to launch payloads other than SpaceShipTwo.
In May 2011, Space Shuttle Endeavour mission STS-134 is due to carry 13 Lego kits to the ISS, where astronauts will build models and see how they react in microgravity, as part of the Lego Bricks in Space program.
In 1998, Frank Pietronigro flew Research Project Number 33: Investigating The Creative Process in a Microgravity Environment where the artist drew, created 'drift paintings' and danced in microgravity space.
The United States Microgravity Payload (USMP-4) is a Spacelab project managed by Marshall Space Flight Center, Huntsville, Alabama.
