Flight by light for CubeSats
CubeSats are tiny satellites that hitch rides to space aboard rockets carrying larger payloads. The low cost of these satellites has 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 has been successfully demonstrated by Japan’s IKAROS mission, and NASA’s NanoSail-D gathered data on using solar sailing as a method of de-orbiting defunct satellites.
The Planetary Society’s LightSail program will take the technology a step further. The LightSail-A spacecraft will go on a shakedown cruise to test sail deployment and spacecraft operations. LightSail-B will attempt to demonstrate controlled solar sailing. Launch dates are coming soon.
