Paper space shuttles set for takeoff

February 06, 2008

The University of Tokyo researchers tested small, origami planes made of special paper for 30 seconds in 250 degrees Celsius (482 F) heat and wind at seven times the speed of sound. The theory is that paper craft, being much lighter than space shuttles, may escape the worst of the friction and heat that much heavier space shuttles face on re-entry to the atmosphere.
