      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.

      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.

      Carl Sagan would be so proud to see a community like this one coming together for the greater good of space exploration. Congratulations and thank you Planetary Society!

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

    14. Tor Lin on

      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.

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

    22. Bill Nye, CEO, The Planetary Society 2-time creator on

      @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!

    23. Dustin Alexander on

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

    24. Ryan Lee on

      Congrats Lightsail team and Bill Nye!

    25. AAW Games on

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

      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.

      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)
