Flight by light for CubeSats
LightSail-1 has a launch date! The Planetary Society's solar sailing spacecraft is scheduled to launch aboard the SpaceX Falcon Heavy in April 2016.
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.

NASA announced that the Planetary Society’s LightSail-1 solar sail mission is on their short list for upcoming launch opportunities. The missions selected are Cubesats destined for piggyback launches as part of NASA's CubeSat Launch Initiative.
