KASHIWA, Japan - Japanese scientists and origami masters hope to launch a paper airplane from space and learn from its trip back to Earth.

It's no joke. A prototype passed a durability test in a wind tunnel this month, Japan's space agency adopted it Wednesday for feasibility studies, and a well-known astronaut is interested in participating.

A successful flight from space by an origami plane could have far-reaching implications for the design of re-entry vehicles or space probes for upper atmospheric exploration, said project leader Shinji Suzuki, a professor at Tokyo University's Department of Aeronautics and Astronautics.

In a test outside Tokyo in early February, a prototype about 2.8 inches long and 2 inches wide survived Mach 7 speeds and broiling temperatures up to 446 degrees Fahrenheit in a hypersonic wind tunnel — conditions meant to approximate what the plane would face entering Earth's atmosphere.

Having survived the 12-second test with no major damage or burns, the tiny plane theoretically could get back to Earth because re-entry from outer space involves passing through several layers that last only a few seconds each, said Osamu Imamura, a scientist who works with Suzuki.

Suzuki and Toda use origami paper made of sugar cane fibers that are resistant to heat, wind and water. They spray a special coating onto the paper and then fold it into shuttles about 8 inches long and 4 inches wide that weigh about 1.05 ounces. How many shuttles will be released has not been decided.

Only problem is they have no way of knowing where or even if the paper shuttles land. I wonder if they could stick on a tiny radio transmitter?
