Wings for discovery

ESA Parabolic Flight Campaign Manager Vladimir Pletser concluding the Parabolic Flight Symposium.

Vladimir Pletser has followed the European flights since they began and is now manager for ESA’s campaigns. He had his first campaign back in 1986 and has seen the scientific progress over the last 25 years. "What we are doing now on the flights is something that we couldn’t imagine in the early days. With the cumulative experience, new technology and advances in science, we can now squeeze an enormous amount of data out of those 20 seconds of microgravity."

Pletser remembers his first flight on the NASA KC-135 aircraft: "I was so amazed about the zero-g that I forgot to start my experiment, and when after some seconds I did remember it, I was floating too far away to operate it!"

In the 1980s, microgravity experiments were conducted on very small scale during the flights organised to train the astronauts for the Spacelab missions. Nowadays, the experiments are housed in big racks and contain Xray imagers, high-speed cameras and other advanced instrumentation. "Still, the most important part of the research is the human being, as a subject or as the operator of the instruments," Pletser reminds us. "The quality of the microgravity research in Europe is very high, mostly down to the ESA parabolic flight campaigns."

Martin Zell, the Head of ESA’s ISS Utilisation Department, acclaims the ESA parabolic flights, too: "These campaigns have provided an outstanding platform for the European science community to conduct experiments in microgravity."

"With the A300 we are able to bring microgravity almost to their laboratory," continues Josef Winter, Head of ESA’s Payloads and Platforms Division. “The increasing number of experiment proposals shows clearly the interest of the European science community in this easy access platform to research under microgravity conditions.”

Zero-G Airbus A300 for parabolic flights

The future of space exploration is already here for the parabolic flight experimenters. On some flights, the pilots of the Airbus A300 ZeroG aircraft were able to fly parabolas where they maintained Moon (0.16 g) and Mars (0.4 g) gravity conditions for about 25 seconds. This year, these flights were officially brought into ESA’s research programme.

Both are interesting microgravity environments that can help to prepare for future missions to the Moon and Mars. Studying the effects of gravity also requires experiments in gravity levels between microgravity and full Earth gravity – and even beyond.
