Solar Sails
Solar sails, a proposed method of spacecraft propulsion, would use radiation pressure from the Sun as a motive force. Private spacecraft Cosmos 1 was to have used this form of propulsion. The idea was proposed as early as 1924 by Soviet scientist Friedrich Zander.
The Japan Aerospace Exploration Agency (JAXA) has successfully unfurled a solar sail in space which has already succeeded in propelling its payload with the IKAROS project.

Famous quotes containing the words solar and/or sails:
“Senta: These boats, sir, what are they for?
Hamar: They are solar boats for Pharaoh to use after his death. They’re the means by which Pharaoh will journey across the skies with the sun, with the god Horus. Each day they will sail from east to west, and each night Pharaoh will return to the east by the river which runs underneath the earth.”
—William Faulkner (1897–1962)
“I call to mind the navy great
That the Greeks brought to Troye town,
And how the boistous winds did beat
Their ships, and rent their sails adown;
Till Agamemnon’s daughter’s blood
Appeased the gods that them withstood.”
—Henry Howard, Earl Of Surrey (1517?–1547)
