A Japanese person throwing a boomerang and having it to return to him aboard the International Space Station is not going to throw the world of aerodynamic studies into chaos. A boomerang should work in any environment with air, if properly thrown. Now, having it return to you in vacuum would be the real trick... perhaps attainable by futuristic laser guided systems. Still, there is something comforting about this video, not only for its playful outer-space quiescence, but because it confirms that we will be able to arm our Australian space marines with their native throwing sticks when the Heliothane come swarming back in time for our natural resources.
