Ikaros Spacecraft Successfully Propelled In Space

An anonymous reader writes "Japan's IKAROS spacecraft has already successfully deployed the first solar sail in space, but today it made the only first that really matters: it successfully captured the sun's rays with its 3,000-square-foot sail and used the energy to speed its way through space. Each photon of light exerts 0.0002 pounds of pressure on the 3,000-square-foot sail, and the steady stream of solar exposure has succeeded in propelling the nearly 700-pound drone."

What do you expect with the linked article from a technically ignorant greenie publication?

Arthur C Clarke did a much better job of explaining the concept with his "Sunjammer" story that appeared in Boy's Life ca 1964.
