Japanese precision machinery manufacturer Castem has sent nine origami space shuttles to the Japan Aerospace Exploration Agency (JAXA) office in Houston, it was announced on October 7. If all goes as planned, the paper planes will conduct experimental flights from the space station to Earth early next year.

The 29-gram (1 oz) origami shuttles, which measure 38 centimeters (14 in) long and 22 centimeter (9 in) wide, are made from lightweight but durable sugar cane fiber paper that has been chemically treated to resist heat and water. Developed by JAXA and the University of Tokyo, the special paper has already been used to construct a miniature prototype shuttle, which was tested in a hypersonic wind tunnel in January. In that test, the prototype survived wind speeds of Mach 7 (8,600 kph/ 5,300 mph) and temperatures of around 200 degrees Celsius (nearly 400 degrees Fahrenheit).

If NASA approves, the Space Shuttle [...]
