Parabolic flight campaign for Fly!

The performance of a lower limb prostheses has been tested in microgravity conditions for the first time during the latest ESA parabolic flight campaign on the ‘Zero G’ aircraft. 

The 86th ESA parabolic flight campaign took off on 21 May 2025 from Bordeaux, France.   

Parabolic flights create short windows of microgravity by flying an aircraft in a curved trajectory called a parabola. During each of the 31 parabolas per flight, John and the team experienced 22 seconds of weightlessness, simulating the conditions on the International Space Station.
