Experiencing zero gravity on Earth
Ever wondered how astronauts prepare for the weightlessness of space? In Bordeaux, France, our astronauts train for microgravity using parabolic flights! These special flights create brief periods of zero gravity, mimicking the conditions of space.
By performing a series of steep climbs and descents, the plane allows astronauts to experience intense 2G forces before entering a 22-second weightless phase! This crucial training helps future astronauts adapt to moving, working, and even jumping in zero gravity.
Join us as we follow Rosemary Coogan, Sławosz Uznański-Wiśniewski, and John McFall on their parabolic flight training.

Floating in zero gravity… on Earth? 🌍 How is that possible?
Air Zero G’s parabolic flights create a weightless environment by flying along a curved path called a parabola. This short period of weightlessness lasts about 22 seconds, during which people and experiments on board the parabolic flight can experience the same weightlessness as astronauts in orbit on the International Space Station.
The price to pay for this free-floating freedom is two short periods of hypergravity, during which everything weighs almost double for 20 seconds: first when the aircraft pulls up sharply and then again when it pulls out sharply afterwards to return to a normal flight path.
Each parabola takes about one minute to complete and is repeated 31 times in one flight, providing a total of about ten minutes of zero-gravity.
The flights provide European scientists with access to a repeatable, low-gravity research environment. Hundreds of experiments have flown over thousands of parabolas, enabling extensive scientific endeavours across many disciplines and resulting in a huge legacy of publications.

Zero gravity Science
ESA’s parabolic flight project coordinator Neil Melville explains why 40 researchers working on 12 technologically-advanced experiments are put in an aircraft that flies at maximum thrust in repeated 50° angles at the limits of the Novespace aircraft’s design.
Parabolic flights offer sessions of 20 seconds of zero gravity giving a total of 10 minutes of weightlessness each flight. The advantage of parabolic flights over other platforms for experimentation in altered gravity is that researchers can join the flight and interact with their experiment – fine tuning hardware, running tests on human subjects or changing parameters on the fly. The experiments are carefully chosen for potential benefits, safety and uniqueness.
Neil highlights some of the experiments on ESA’s 72nd campaign that covered disciplines as diverse as astronomy, cooling techniques, metallurgy, weather and human physiology.
The Progra2 experiment is creating clouds of matter and recording how light is scattered by micrometre-sized particles. The carbon-based dust is chosen to resemble the clouds found in our Solar System such as around asteroids and comets. Knowing how light is scattered by these particles in microgravity will help interpret observations made from telescopes and increase our understanding the Universe.
An experiment from the Université Libre de Bruxelles in Belgium is looking at healing wounds with bio-mimetic materials by submitting them to mechanical stresses typical in weightlessness. The knowledge acquired will pave the way for the development of biophysical models and a have a direct impact on the industrial market of wearable electronics.
The VIP-GRAN team is looking into how particles behave in reduced gravity to understand the underlying physics in detail. On this flight they investigated the jamming of particles as they flow through small openings. This can be an annoyance on Earth when salt gets stuck in the shaker for example, but the phenomenon is influenced by gravity and the researchers want to know more. This was the ninth flight for the VIP-GRAN team and who are working towards having a version of their experiment fly on the International Space Station with even more weightless time.

ESA’s 71st parabolic flight campaign experiments
Engineers, pilots, researchers and scientists convened in Bordeaux, France, for ESA’s 71st parabolic flight campaign. Over the course of three days they flew on a specially-fitted commercial aircraft, testing equipment and running research as the pilots put the plane through repeated parabolas, giving the passengers and their experiments brief bouts of microgravity.
ESA’s project coordinator Neil Melville introduces the experiments that flew on this campaign, from plasma to granular physics and heat pipes.
Parabolic flights are one of many platforms ESA offers for European researchers to run experiments for spaceflight. These flights are one of the few that allow the researchers to interact with their own experiments “hands-on” in a weightless environment. Send a proposal through our continuously open research announcements and you could be flying on the next campaign.

Visit the ISS in 3D with Paolo Nespoli
Paolo Nespoli spent 6 months on-board the International Space Station from Dec 2010 through to May 2011.
In this video he shot using ESA’s Erasmus Recording Binocular (ERB-2) stereoscopic camera during various phases of his MagISStra mission, he caught some moments that depict the work astronauts carry out on the ISS: from educational activities, to scientific experiments and physical training, also demonstrating the way astronauts move in weightlessness through the various modules. ERB-2 is the first camera to transmit 3D images live from space.ESA would like to thank all the astronauts featured in the film: NASA astronauts Catherine (Cady) Coleman, Ron Garan, Scott Kelly and the united ISS Expedition 26-27 and STS-134 crew including ESA astronaut R. Vittori.

How do you feel after the first few months in orbit?
Frank De Winne is answering a few questions on the ISS submitted by the pupils of Class 7M from the Christian Morgenstern School in Hersching (Germany):
Question:
– Jerome (13): How do you feel in orbit after 2 months?
– Karina (13): How much time do you spend working outside the ISS?
– Tamara: Do you have any real free time in the ISS, and how can you spend this time? How often do you contact your family?
– Antoine (13): Have you ever felt scared in orbit? Has there ever been a moment that you wished to be back on Earth?
– Regina (14): Has anything strange happened on the ISS that none of your colleagues have been able to explain?
– Flavu: Which kind of education and qualification do you need for this kind of work? -
