NASA is preparing to test a new space sail this summer that uses sunlight to provide this acceleration, whereas a scientist at the Finnish Meteorological Institute is refining a design for a different type of space sail that would have spacecraft surfing the solar wind, a continuous stream of charged particles that emanates from the sun, at speeds nearly twice that of Voyager 1 (18.6 miles, or 30 kilometers, per second).
