The Japan Aerospace Exploration Agency (JAXA) has released a video of Japanese astronaut Takao Doi experimenting with a specially designed boomerang at the International Space Station (ISS) in March 2008…
Conclusion… the boomerang reacted just the same under zero gravity as it would be on the ground. Aerodynamics expert David Caughey of Cornell said that the result is as expected – the looping paths are the result of uneven forces on the curved devices by the air they travel through, not the influence of gravity.
The boomerang was working in the space station, but would not work in the “real” outer space though. Boomerang expert and designer Gary Broadbent said that a boomerang would not work in the vacuum of space, as air molecules are needed to generate the lift to make the boomerang turn.
