S2012E27 IKAROS: The World's First Solar Sail Spacecraft

With IKAROS (the Interplanetary Kite-craft Accelerated by Radiation Of the Sun), the Japanese space program has amazed the world. IKAROS is the world's first spaceship that can fly about freely in space without a mechanical engine. It's like something out of science fiction. How exactly does IKAROS propel itself? The idea behind IKAROS was first conceived by a U.S. research institution a century ago, but it took uniquely Japanese talent to make it a reality -actually, origami was a crucial source of inspiration for the engineering team. Now, a new, larger craft modeled on IKAROS is being designed to explore our solar system. It is expected to take flight in 2020. IKAROS is promising to change the shape of space exploration.
