Now that the primary goal of this mission is complete, the Planetary Society will use what they've gleaned from this go around to further strengthen their next test of LightSail, scheduled for 2016. For that test, which the non-profit is partially funding through Kickstarter, a spacecraft outfitted with solar sail technology will be launched into much deeper space—about 450 miles above the surface of the Earth. There the solar sails will both deploy and catch the breeze of solar winds, sailing on the high seas of the interplanetary vacuum. If that proves successful, solar sailing could dramatically reduce the cost of future space travel for unmanned spacecraft, says Nye, since no propellant is necessary for the sails to function. All you need is the ever-accelerating photons shooting out from the Sun.
