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.
It's been a few weeks since LightSail 2 passed its day-in-the-life test at Cal Poly. Here's a roundup of updates that were made in response to the test results, and a look at the project's next steps.
The Planetary Society's LightSail 2 (.-.. / ... / ..---) spacecraft will identify itself from orbit using Morse code, and you can make the sound your ringtone.
The Planetary Society's LightSail 2 spacecraft breezed through a major systems test today, demonstrating the CubeSat can successfully deploy its antenna and solar panels, communicate with the ground, and unfurl its 32-square-meter solar sails in space.
