Parabolic Flights

Human-Operated Microgravity Research


Parabolic flights are the only sub-orbital carriers that allow scientists to conduct experiments in person under microgravity or reduced gravity conditions. They provide a unique opportunity to test biological, biomedical, physiological, physical, and material science experiments in a real flight environment.

Why Parabolic Flights?

These campaigns enable:

  • Hands-on experimentation during short periods of weightlessness
  • Gravity level flexibility between 0g and 1g for specific research needs
  • Validation of hardware and procedures before space missions

Parabolic flights are ideal for studies requiring crew interaction, real-time observation, and rapid prototyping.

ESA’s Role

ESA organises Parabolic Flight Campaigns twice per year (Spring and Autumn) using the Airbus A310 ZERO-G, operated by Novespace from Bordeaux-Mérignac Airport.

  • Each campaign includes three flights, with 31 parabolas per flight (93 per campaign)
  • Each parabola provides about 20 seconds of microgravity, totaling ~10 minutes per flight and ~30 minutes per campaign
  • Intermediate gravity levels (between 0g and 1g) can be requested, though such campaigns are rare
