Planetary Society - LightSail-1 Mission

The Planetary Society’s Solar Sail Will Hitch a Ride to Space on a Falcon Heavy
by NANCY ATKINSON on JULY 10, 2014

In a live webcast, The Planetary Society CEO Bill Nye announced that its long-awaited LightSail solar sail mission will launch to Earth orbit on a SpaceX Falcon Heavy, currently scheduled for an April 2016 liftoff. LightSail-1 and its parent satellite, Prox-1, will be on the same launch vehicle as the U.S. Air Force’s Space Test Program 2 (STP-2) mission. If successful, it will be the first CubeSat to demonstrate controlled solar sailing.

“It’s fantastic that at last we have a launch date for this pioneering mission,” said Nye.

The Planetary Society has raised over $4 million for the mission, but according to Jason Davis from TPS, the launch costs will be paid by the USAF and Georgia Institute of Technology, which developed the Prox-1, a technology demonstration for using small satellites to autonomously inspect other spacecraft.

LightSail will go to an orbit about 720 km above Earth, stored inside the Prox-1, which was developed by the Georgia Institute of Technology to demonstrate new technologies enabling two spacecraft to work in close proximity. After ejecting LightSail, the largely student-built Prox-1 will track and image LightSail, including the sail deployment.

Cool. It's another small step towards making futuristic sci-fi into an actually really real reality.
Freedom's just another word for nothin' left to lose,
And nothin' ain't worth nothin' but it's free.

And what's just as cool is that it is being done by public sourced donations and management not a government agency/entity. :)

Down to 4 people now, I wonder what happens next.

Back up to 8, now! And we have a, sort of, sound feed too...

Couple of minutes ago (19:42 BST) via twitter:

Solar sail successfully armed for deployment.

MOTOR ON. Telemetry shows #LightSail2's sail deployment motor is active.

1954-ish
DEPLOYMENT COMPLETE! Telemetry shows motor has reached target count!


Woohooo!
