On July 9th, JAXA (the Japanese Aerospace Exploration Agency) announced that they had successfully deployed and used a solar sail—a 2,153 square foot foil membrane that accelerates a space ship with sunlight and solar wind. At about 0.00025 pounds of force, the acceleration is tiny; but the ship is lighter due to lack of onboard fuel, and that acceleration can continue right through the flyby of Venus in six months.
Even stranger is the use of LCD screens near the edge of the sail, which allow the sail to change its angle by varying the amount of light reflected from the screens. Of course, they’re powered by solar cells further in on the sail.
If the IKAROS is successful in its flight, later this year JAXA will launch a new satellite with nearly 13,500 square feet of sail area. This time, the goal will be to visit Jupiter and the Trojan asteroids.
