The sci-fi inspired mission, Sunjammer, is named after Arthur C. Clarke’s 1964 tale of sun-yacht races through the solar system and will carry the ashes of Star Trek creator Gene Roddenberry and his wife Majel Barrett Roddenberry to the mission’s destination, a gravitationally balanced orbit between the Earth and Sun (L1). Sunjammer’s sail is a third of an acre, about 124 feet to a side, and seven times the size of the Japanese Aerospace Exploration Agency (JAXA) and Planetary Society’s solar sail IKAROS, the biggest sail successfully launched to date."
