IKAROS, the first space-probe with a solar sail in flight (artist's depiction), featuring a typical square sail configuration of almost 200 m 2. Solar sails (also known as lightsails, light sails, and photon sails) are a method of spacecraft propulsion using radiation pressure exerted by sunlight on large surfaces. A number of spaceflight ...
Interstellar Probe is the name of a 1999 space probe concept by NASA intended to travel out 200 AU in 15 years. [1] This 1999 study by Jet Propulsion Laboratory is noted for its circular 400-meter-diameter solar sail as a propulsion method (1 g/m 2) combined with a 0.25 AU flyby of the Sun to achieve higher solar light pressure, after which the sail is jettisoned at 5 AU distance from the Sun.

Artist's concept of a heliogyro, proposed to visit Halley's Comet in 1986. Each blade would be 8 m (26 ft) wide and 6.2 km (3.9 mi), for 0.6 km 2 (0.23 sq mi) of sail area. Solar sail types. A heliogyro could have dozens of blades. UltraSail is a proposed type of robotic spacecraft that uses radiation pressure exerted by sunlight for propulsion.
The IKAROS probe is the world's first spacecraft to use solar sailing as the main propulsion. [14] It was designed to demonstrate four key technologies (comments in parentheses refer to figure): Deployment and control of a large, thin solar sail membrane (grey-blue areas numbered 3)
[134] [135] Such an interstellar precursor could easily pass by ʻOumuamua on its way out of the Solar System, at speeds of 63 km/s (39 mi/s). [136] [137] More advanced options of using solar, laser electric, and laser sail propulsion, based on Breakthrough Starshot technology, have also been considered. The challenge is to get to the ...
The objectives of the CubeSail mission are to demonstrate the concept of solar sail propulsion of a 3-axis stabilised 25 m 2 solar sail for one year while in low Earth orbit; and to demonstrate the use of gossamer structures (very light gauze-like fabric) as a drag augmentation device for satellite de-orbiting.

Interstellar Probe was a proposed solar sail propulsion spacecraft planned by NASA Jet Propulsion Laboratory. It was planned to reach as far as 200 AU within 15 years at a speed of 14 AU/year (about 70 km/s, and function up to 400+ AU). [40] A critical technology for the mission is a large 1 g/m 2 solar sail. TAU mission (1987)
LightSail 2 with deployed solar sail, 23 July 2019. LightSail 2 (COSPAR 2019-036AC) was a CubeSat fitted with a solar sail the size of a boxing ring, covering 32 m 2 (340 sq ft). The sail captured incoming photons from the Sun, just as a wind sail catches the moving air molecules, to propel the spacecraft. [30]
