The mylar sail, which is about as big as a boxing ring and thinner than a human hair, is solar-powered -- but it's not a solar panel. It's a sail just like one you'd find on a boat, but it uses the natural momentum of the sun's photons instead of the push of wind. The force is small, but continuous. "With a chemical rocket, there's a big boom, a phwooosh, the ground shakes, but then nine minutes later you're done and you're coasting all the way to Pluto," Nye told The Post back in January. "With these kind of sails, the propulsion doesn't just stop. It's on day and night -- except wait, there's no night!"
Because the sail is so delicate, deploying it is easier said than done. That's the purpose of the current mission: The sail and the tiny CubeSat it's attached to won't be doing anything fancy this time around, but hopefully Nye and the rest of his team will see that it's possible for the sail to unfurl without a hitch. Or without any more hitches, anyway.
In 2016, the group will launch a full mission. The Kickstarter campaign to fund that trip has already surpassed its $200,000 goal (in fact, it's at over $790,000 with 25 days more to go) so if LightSail can manage to deploy, all systems are go.
But wait: You were promised a video of The Science Guy surfing. And here it is:
Nye and his team shot the video to celebrate LightSail's successful launch, but by the time they emailed me an embargoed clip (yes, I get embargoed clips of Bill Nye surfing, aren't you jealous) LightSail was incommunicado, so it was kind of a bummer. When things took a turn for the better, Nye had the video released early to celebrate.
Enjoy Bill Nye the Surfing Guy, and hopefully we'll have another LightSail update soon.
