KASHIWA, Japan (March 27) - Japanese scientists and origami masters hope to launch a paper airplane from space and learn from its trip back to Earth.
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.
