LightSail, developed by The Planetary Society, will demonstrate that sunlight alone can propel a spacecraft in Earth orbit. It is a follow up mission to the failed Cosmos 1 project.

Taking advantage of the technological advances in micro- and nano-spacecraft over the past five years, The Planetary Society will build LightSail based on a 3 Unit Cubesat spacecraft. One unit will form the central electronics and control module, and two additional units will house the solar sail module. Cameras, additional sensors, and a control system will be added to the basic Cubesat electronics bus.
