Dear Planetary Explorers - 


We did it! Together. Because of you, we met our final stretch goal on our way to a successful LightSail mission in 2016. Our spacecraft will fly on Falcon Heavy to a higher orbit where we will demonstrate true solar sailing. 

This mission now belongs to all of us. Thank you. 

Let's change the world! 

P.S. We will begin the post-campaign surveys soon.  Watch for that process to begin in the weeks ahead.

      My first project to support on kickstarter. Glad I was able to put in my little bit for such an important project. I am proud to be part of this community. Thanks Bill Nye for getting this out there.

      Carl Sagan would be proud of your efforts, Bill Nye, and it is like you are walking in his footsteps. He sat next to me in Bailey Hall at Cornell University once during a lecture and he was about as down to Earth as a person could get-who knew his head was always in the clouds!! (affectionately said)

      I'm very happy to have been able to help. I would love to see lightsail spacecraft zipping around the solar system in the future.

      I'd like to propose we christen the first true Light Sail Starship the L.S.S Carl Sagan

      I have only backed a handful of Kickstarter campaigns, and I am proud to count this as one of them.

      Yeeeee of course I'd support my nigga, Bill Nye!

      This is a kickstarter that I am extremely proud to be a part of and very excite to watch happen. Also I own part of a spaceship. -squee-

      This is the first time I pledge a project on kickstarter. So excited for the new age of solar sail. Let's make history together.

      So happy I could contribute to this project. While I am no expert scientist or even a decent scientist, I love looking up information about planets and such, especially the infinite possibilities about exoplanets. I love coming across information such as the size and the period of time Jupiter's red spot has been active and thinking "I can't even imagine that here."
      Thanks again, Bill Nye and all of the team making this possible.

    17. AAW Games on June 26, 2015

      Thank YOU Bill!
      Extra special thanks to the great Carl Sagan for dreaming big and passing on his dreams to the next generation.

    18. Ryan Lee on June 26, 2015

      Congrats Lightsail team and Bill Nye!

    19. Dustin Alexander on June 26, 2015

      Thank you for helping to keep science at the forefront of people's minds and allowing us to dream!

    20. Bill Nye, CEO, The Planetary Society Creator on June 26, 2015

      @Ian - no sneaky revision. We actually worked-up a budget in consultation with our Program Manager, Doug Stetson, and put that out as the stretch goal. The addition we needed above $1 million is, actually, $240,000. We have some additional budgeting yet to do for some spacecraft hardware, but those numbers were "hard" enough yet to include. We will do some additional private fundraising to meet the final total needed. Some folks would have expected us to simply round-up to the $1.25 mark, but we chose to call it straight. Thanks for raising the question!

    21. Marc Mackin on June 26, 2015

      Say no to Vertical video, Bill Nye as a scientist you should know better.

    22. Robert Araujo on June 26, 2015

      Glad to be part of this project!

      Awesome! Congrats, Bill and everyone!

    28. Tor Lin on June 26, 2015

      my sentiment may be a bit petty but I'd rather spend my money here, advancing science, than (taxed) to be turned into bombs to be dropped around the world.

      It's obvious how much this project means to Bill and the rest of us. Keep up the good work everybody!

      Its will be great, if humans think nore about space and science vice versa war and politics.... if that happens, all of us will live more happy, that now.

      Well the change from 1.25 to 1.24 I think has to do with the 100k that is being matched? So they were able to revise the amount actually needed.
