Scientists Aim for Origami Space Flight

The pair theorize that with the coating, rounded edges, a rounded nose cone and almost no weight, their craft will face very little of the heat-generating friction that causes most damage to vehicles re-entering Earth's atmosphere.

Astronaut Koichi Wakata, who has expressed personal interest in the project, would throw several origami shuttles into the wake of the international space station, which travels at Mach 20 some 250 miles above Earth if the JAXA feasibility studies pan out, Suzuki said.

Findings from the paper shuttles' flight could be used in developing new lightweight space probes that would study the upper atmosphere, Miyazaki said. The results also could help in designing a full-scale shuttle that re-enters the atmosphere slowly to reduce fiction and heat, said Suzuki.

Suzuki and Toda plan to write a message of peace on the planes in several languages, along with a request for anyone spotting them to notify the team.

"Just imagine, children around the world would be anxiously waiting for the return of our origami shuttle, perhaps looking up into the sky from time to time," Suzuki said. "That would be great fun."
