Weightless flight

Parabolic flights provide short periods of weightlessness, offering a quick way to test things in microgravity with humans. Researchers use them for short-duration, hands-on scientific and technological investigations, such as training astronauts and validating instruments before they fly to the International Space Station. 

The aircraft can also fly over a gentler trajectory, providing partial gravity like on the Moon or Mars. Lunar and martian gravity levels are not only scientifically interesting but it is also useful to test the effect on humans and equipment before travelling to these destinations. 

ESA is now opening these unique aircraft doors to two types of experiment, for up-and-coming new technologies in a changing space sector: technological and commercial.
