The primary distinction between life on the Worldwide Area Station (ISS) and life right here on terra firma is microgravity, which forces you to drift round quite than stroll.
To organize beginner astronauts for such circumstances, NASA, or on this case, the European Area Company (ESA), takes new astronauts on particular flights which can be capable of imitate — albeit briefly — the area station’s microgravity atmosphere. The vital coaching allows the astronauts to get used to shifting, working, and even leaping in microgravity. In the event that they get actually good, they’ll be capable to dance, too.
ESA not too long ago shared a captivating video (high) displaying what it’s prefer to expertise certainly one of these so-called “parabolic flights,” that are a key a part of an astronaut’s coaching.

Because the video reveals, the “Air Zero G” plane — an Airbus A310 — creates the situation of weightlessness by climbing sharply for 20 seconds earlier than dropping for 22 seconds. Throughout this transient however sharp descent, the trainee astronauts can float across the cabin, giving them some thought of what it’ll be like aboard the ISS.
Every parabola takes about one minute to finish, with the method repeated 31 occasions in a single flight to offer a complete of about 10 minutes of zero gravity circumstances.
The video reveals ESA astronaut Rosemary Coogan climbing aboard the plane for a parabolic flight. Previous to takeoff, Coogan provides a fast tour of the airplane, which features a small seating space the place everybody straps in through the ascent and likewise the return a part of the flight.
Past the seating space is the place the all of the motion takes place. Cleared of seats, the massive open area provides astronauts and trainers loads of room to maneuver round, though free floating is confined to a comparatively small space surrounded by security netting.
What’s it prefer to float within the air? “It’s arduous to check it to something on Earth,” says the presenter. “For me, the closest feeling may be floating in water however with out the resistance or capability to steer your self.”
One other part of the plane is given over to researchers, offering them with an area the place they will conduct science experiments in microgravity circumstances with out leaving Earth’s environment.
Whereas the interval of weightlessness aboard the flights solely lasts for a short time period, astronauts on the ISS should stay in such microgravity circumstances across the clock for months on finish. To seek out out extra about what it’s prefer to exist in such an atmosphere, take a look at these movies made by the astronauts themselves throughout missions aboard the orbital outpost.
