Parabolic flights treat passengers and experiments to a rollercoaster ride, flying angled at 49º 20 times per flight. They are used to conduct short-term scientific and technological investigations in microgravity and reduced gravity, to test instrumentation before use in space, to validate operational and experimental procedures, and to train astronauts for spaceflight.
This picture was taken during the first flight day of ESA's 72nd parabolic flight campaign in November 2019.
