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 ...
At such extreme long range the antenna would be unable to provide any propulsion, but Starwisp would be able to use its wire sail to collect and convert some of the microwave energy into electricity to operate its sensors and transmit the data it collects back home. Starwisp would not slow down at the target star, performing a high-speed flyby ...
The Znamya 2 was a 20-metre wide space solar mirror. Znamya-2 was launched aboard Progress M-15 from Baikonur on 27 October 1992. After visiting the EO-12 crew aboard the Mir space station the Progress T-15 then undocked and deployed the reflector from the end of the Russian Progress spacecraft on 4 February 1993, next to the Russian Mir space ...
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)
A giant solar sail recently unfurled by Nasa has been spotted “tumbling” through space.. Astronomers captured the 80-square-metre object, which was unfurled last week, appearing to fluctuate ...
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]
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.

A preliminary mission outline suggests the use of solar sails [4] propelled by high energy lasers to increase propulsion. [4] The proposed launch would be on the 100th anniversary of the Apollo 11 mission. [6] The spacecraft would reach Alpha Centauri by the year 2113, 44 years after its launch travelling at 10% of the speed of light. [3]
