It’s going to be a big year for LightSail—we’re headed to space! First, we will test our prototype this month and next by flying it in low-Earth orbit for about 30 days. While our Kickstarter campaign runs, you’ll be able to follow along in real-time as we validate the deployment of our sail booms in zero gravity as well as other key spacecraft characteristics. This is a huge opportunity for us to learn and apply lessons from the test program to the primary mission currently scheduled for fall 2016.

Here’s where you come in. The final bill for LightSail is projected at $5.45 million, of which we have just over $1.2 million left to raise. We’re nearly there, but our final push will be critical to getting to the launch pad next year. So we’re reaching out to the Kickstarter community for backing at this key moment. We invite you to get on board the mission and help LightSail soar. Without your support, the project can’t happen.

We don’t expect to get this all from one source at one time, but you can put us on the trajectory to launching in 2016. We are setting an ambitious Kickstarter goal of $200,000, with stretch goals that take us all the way up to the $1 million mark. These goals will take us from 1) spacecraft construction, integration and testing; 2) through orbital operations (actual solar sailing!); 3) to data collection, analysis, and publication of results; and 4) a slew of public awareness and education activities to make sure solar sailing is widely noticed and adopted.
