As of 2015, it was still under thrust, proving the practicality of a solar sail for long-duration missions. [53] It is spin-deployed, with tip-masses in the corners of its square sail. The sail is made of thin polyimide film, coated with evaporated aluminium. It steers with electrically controlled liquid crystal panels. The sail slowly spins ...
Sunjammer (Solar Sail Demonstrator) was a NASA mission intended to demonstrate a solar sail constructed by LGarde, but was canceled before launch.The largest solar sail made as of 2013, Sunjammer was named after a 1964 [1] Arthur C. Clarke story of the same name, Sunjammer, in which several solar sails compete in a race to the Moon. [2]
The mission would have used a Jupiter gravity assist [59] and a Uranus flyby to reach and explore Kuiper belt objects.

NanoSail-D2 was a small satellite built by NASA's Marshall Space Flight Center and Ames Research Center to study the deployment of a solar sail in space. It was a three-unit CubeSat, measuring 30 cm × 10 cm × 10 cm (11.8 in × 3.9 in × 3.9 in) with a mass of 4 kg (8.8 lb). [3]
An artist's depiction of a solar sail. In December 2017, NASA released a mission concept involving the launch, in 2069, of an interstellar probe to search for signs of life on planets orbiting stars in and around the Alpha Centauri system. [1] [2] The announcement was at the annual conference of the American Geophysical Union. [3]
The spaceship will compensate for the low thrust by having a mass of only a few grams. The camera, computer, communications laser, a nuclear power source, and the solar sail must be miniaturized to fit within a mass limit. [25] [29] All components must be engineered to endure extreme acceleration, cold, vacuum, and protons. [26]
