solar sail n.

[quoting an unnamed scientist:] Striking the aluminium side of a large solar sail, the rays would cause it to accelerate. A manned vehicle attached to the sails by lines would be capable of going to any point in the solar system.

Another interesting concept which has not yet really undergone feasibility determination is that of the solar sail. With this device, a space ‘ship’ may some day be able literally to sail through interplanetary space.

The material of the two silicate asteroids was transformed by their robot crews into sheets of solar sail material.

The image you see is caused by a tremendous reflector-and-energy-collector…a solar sail.

Time meant nothing to the bioprobes' dreamless minds, chilled almost to coma in the payload of the immense solar sail.

My hopes die when I look at the collapsed solar sail—during the crash, one of the ship’s structural beams impaled it.
