Boomerang in Zero gravity - Yes it returns

Posted May 02, 2008 9:04 AM
User-tagged by 1 user

From Newlaunches.com:

It was believed that a boomerang returns to the throwing spot in zero gravity, this is what Japanese Astronaut decided to find out at the International Space Station. The above video shows how it went through. Now, thanks to JAXA's obsession with cameras we have proof on video. The usual skeptics who think that Elvis is really the only human that ever went to the moon - and still lives there - will be happy.

That's a boomerang? Looks more like a propeller. I didn't see if change directions--just circled.

It was known for many years, that the "boomerang effect" is a combination of kinetic energy and aerodynamics.

If this had been tried in an airless situation, it would not have been able to return in the normal way.

I do note a 3-lobed rotor device was used, and of course such a device is not a "boomerang" at all.

Kind Regards....
