The Planetary Society returns to the Crawford Family Forum with an evening devoted to the revolutionary potential of solar sailing. It has been called the only practical way to reach the stars, but driving spacecraft across the solar system with the pressure of sunlight also offers big advantages over traditional rocket engines. Closer to home, it offers access to unique orbits for vital Earth science and space weather missions. LightSail will spread its silver wings once it reaches orbit, becoming visible to nearly everyone on Earth as it demonstrates this promising new technology for space travel. Host Mat Kaplan of Planetary Radio will be joined by Planetary Society CEO Bill Nye the Science Guy for a conversation with the designers and engineers behind the Society’s tiny yet highly innovative “cubesat,” along with the history and promise of solar sailing. The evening will climax with an exciting announcement about how LightSail will begin its journey.
Let's try this again: The Planetary Society is announcing tonight they will launch their LightSail solar sail on a Falcon Heavy in 2016.LightSail will be deployed from another smallsat, Prox-1 from Georgia Tech, into MEO; presumably flying as secondary payloads on the FH.The society's release adds that a "test flight of LightSail on a smaller rocket may also be conducted in 2015" in LEO.
The possible earlier test flight of LightSail would be circa May '15 (as a secondary payload on an Atlas V through NASA's ELaNa program.)
I haven't heard what the Falcon Heavy primary payload for the LightSail mission is, but I'd guess the STP-2 mission for the Air Force.
The Planetary Society release said LightSail would go to MEO, but also described the orbit as 720 km—too low for any usual MEO definition.
