At 1504 UT on Wednesday, May 20 the first of The Planetary Society’s two LightSail spacecraft blasted off into space aboard an Atlas V rocket with the X-37B space shuttle. Deployment of LightSail took place at 17:05:40.620 UT. The mission is a shakedown cruise designed to test out the CubeSat’s critical systems.
There were ten CubeSats including LightSail-1 in the UltraSat Deployer onboard the Atlas V. Information on these satellites is at http://www.spaceflight101.com/afspc-05-secondary-payloads.html
The Psat and BRICSat-P CubeSats carry amateur radio PSK31 transponders for multi-user PSK31 text messaging. Psat A/B also has APRS.
LightSail-1 has a 9600 bps FSK AX.25 Packet Radio downlink on 437.435 MHz. The Planetary Society’s Jason Davis asks radio amateurs to help by emailing him any data you collect from LightSail, including screenshots of the radio signal if you have them. He’ll pass the information on to the engineering team, and your contribution will be recognized on the blog. The contact address is at http://www.planetary.org/about/staff/jason-davis.html
Jason provides a timeline of the launch events at http://www.planetary.org/blogs/jason-davis/2015/20150518-lightsail-first-day-space.html For the latest updates follow him on Twitter @jasonrdavis
In 2016, the second LightSail spacecraft will piggyback into orbit aboard the first operational flight of SpaceX’s new Falcon Heavy rocket for a full-fledged solar sailing demonstration.
This video about the project features Bill Nye (the Science Guy on PBS TV) as well as Justin Foley KI6EPH, Alex Diaz KJ6KSF and Stephanie Wong.
