LightSail-1 Mission Trailer

CubeSats are tiny, low-cost satellites that have opened up new avenues of space research for universities and small organizations.

In order for CubeSat applications to reach the next level, the miniature satellites need a reliable form of propulsion for orbital maneuvers and trips beyond our planet. This is where solar sailing—transferring the momentum of photons to a large reflective sail—comes in. The technology was successfully used by Japan’s IKAROS mission in 2010, and NASA’s NanoSail-D test-deployed a CubeSat solar sail in Earth orbit later that year.

In 2016, The Planetary Society’s LightSail program will take the technology a step further. LightSail-1 will attempt to demonstrate controlled solar sailing—flight by light—for CubeSats.
