      Bill, great going,... but I think I did not receive (all) my rewards for this campaign. Could you have that checked and have me PMed about this to take care of it? Tx!

      Ad astra!

      Hi Over the Moon on SpaceX Heavy Lifter!

      Planatary Society Membership: I have received my membership card and number, thankyou.

      How do I log into as a member?

      Eon Musk and his 6000 strong team at SpaceX have succesfully launched a payload on a Mars Earth trajectory, plonking Starman riding a Tesla into an orbit around The Heart of the Sun! From our trip around the Dark Side of the Moon Earth is waking up.

      We always had the vison, now we have the tools, the Mars landing countdown just took a giant leap forward.

      I can't wait for Light Sail to addd to this mix.

      Crazy Idea: Is it possible for radio amateurs to build a rig capable of receiving telemetry from LighSail 2? What are the signal specifications )frequency, modulation, data rate, etc.? In these days of software defined radio, it shouldn't be that hard to receive the telemetry.

      Hello folks, I did receive my centimetre of sail and certificate, but I have not received the Firecell/blanket/tote. If these were shipped already, is tracking information available? Thanks

    9. Bill Nye, CEO, The Planetary Society Creator on December 28

      @Brian we are still fulfilling Certificates of Sail - if you've had a change of address, please send it to Yours may have been sent but to the old address. Thanks!

    10. Brian on December 28

      I got everything but the certificate and my piece of sail. I've moved since backing this. I've accepted that I will never get it, now.

      I only just recently got the Planetary Society magazine (about the Eclipse), so considering how botched that was handled, there's no point in getting upset or surprised if I get it or not.

    11. Johnathan Butterworth on December 12

      I still have not received my backer rewards. I guess I'm not going to at this point.

    12. Henry Charles Young (Spazturtle) on November 27

      He just doesn't care about us, all Nye cares about is his moment of fame from this, he has gone from being a respected science ambassador to being an anti-science mouthpiece who screws over those who helped him.

    13. トーマス・ジャック on November 27

      I have since moved and never received my sail, is there a way for me to update my address? For the life of me I cannot find the original email for the backer kit info.

      Laura MacDonald on November 27

      I got my add on rewards the pins and such, filled out the backer form or else they would not have arrived. But never got my centimeter of sail and certificate backer reward

    15. Rúben on November 27

      This never happened to me and I never got my google form at all. It feels like this was years ago. Lost faith in this to be honest:

      "In the most recent Kickstarter update, #73, we shared our final steps to complete the rewards process. First, we sent Backerkit surveys to those backers who still had not yet completed that step, and set a deadline of November 27th. If you received the reminder and completed it, thank you! Those rewards are in the process of being shipped.

      The next group to tackle was those who pledged to LightSail and had designated their rewards to someone else as a gift. Those backers were sent a Google Form to complete(...)

      I have just received my centimetre of sail and certificate. Thank you. Excessive amounts of patience required on this one.....

    17. Linda Alcorn-Burg on October 27

      I still have not gotten my backer rewards. I'm very sad.

    18. Robin Canfield on October 18

      How I envy the people that actually received their cm of sail.

    19. Rúben on October 7

      Still no cm of sail and both myself and the person I pledged for moved addresses (and country). Hoping to hear back from you guys. You day...maybe? :)

    20. Kyle Boone on October 1

      How can i confirm my address? I have moved since backing and concerned i will not get my cm of sail.

    21. Jacob on September 18, 2017

      Received my cm of sail and can't wait for the launch of LightSail2. Good Luck!

      Joel Baxter on August 27, 2017

      Yep, I just got my membership in the mail too. Along with a letter explaining that my info had been one of a few that needed extra manual repair/processing. Which is puzzling, since they had already sent me my sticker & pin like a year ago, but, whatever. Glad they eventually followed through. Still thoroughly puzzled at the communication failure from this organization.

    24. Tor Erik Tobiassen on August 25, 2017

      Holy moly! Finally got my cm o'sail!! I had written that of like a year ago.. Totaly stoked and ready to proudly frame it an show it off for the launch of lightsail 2. Thanks guys! :)

      I received my certificate, but it's the name of my mother on it. As i was moving when i was asked my adress for the shipping of the hoodie, i gave the one of my mom to be sure to receive it. Now she's a confused space explorer policy advocate. ^^ Doesn't matter, i didn't backed for the goodies, i backed for sending lightsail into space! And i'm looking forward to this moment!

      We joined to support the vision of The Planetary Society and all those involved to further space exploration and knowledge. The"gifts" of pins, t-shirts, decals, and a centimeter of sail are great incentives, but was not our incentive to be a member and part of the Society and family. We will continue to participate in spite of receiving or not receiving "gifts" which we seen many have talked about. Keeping the faith, spreading their founders' vision, and being human.
      (Incidentally, there are at least 6 newsletters you can access, at your membership request site.)

      finally got my centimeter of sail! it's so beautiful... and tastes like mango. unexpected.

      I received The Planetsry Report magazine in the mail today which is included in the that all membership is? No online access to updates about what the society does? CM of sail?

      Since they are too busy mailing me my cm of sail to post any updates, here's a link from their site about the lightsail launch getting pushed back to next summer.

    32. David Markland on July 18, 2017

      I received a reply to an email a month ago telling me my membership would be extended a year (though I've yet to receive membership info to begin with) and other rewards.
      That was a month ago.
      No follow up since.

    33. Carl Nelson on July 15, 2017

      I always assumed the centimeter of sail was symbolic.

      Sean on July 13, 2017

      Like many others it seems I've yet to receive the centimetre of sail certificate and membership. One of the main reasons why I chose to back this project other than to assist in the progress of science and space travel. I still hold some hope that this will get sorted but after so long I'm not liking my chances. At the very least an update would be nice

    35. Russell Nightengale Jr. on July 12, 2017

      Whats the status on the CENTIMETER OF SAIL rewards??? I have yet to recieve mine.

    36. Steef de Jong on July 12, 2017

      Nye, quite the fall from grace.
      From "respected man" to Anti-Science guy, in 2 years.

    37. Tsveta Koleva - Idle/Wild on June 22, 2017

      Got a nice promotional email with the incredible proposition to pay for a membership.

      Angry? You betcha.

      I received emails announcing a store and welcoming me to the Planetary Society.

      There are no instructions as to how I can access this memebership! All I am getting are email/newsletter updates.

      Also, no information regarding centimetre of sail.

      This is unsatisfactory!

      Anton on June 14, 2017

      Ok I have gotten an email letting me know they have a shop now.
      So maybe try to send the centimeter of sail AND the membership.

      You know fullfill what your backers paid for??

      I too have not received my centimeter of sail or the membership. I did get the badge but I was really eagerly looking forward to the membership and to support them in future endeavours. It would be great if we got actual news instead of sending email updates about new online store opening (which they offer a discount to members but none of us here can utilise it because we haven't got our membership). It's a real disappointment to see The Planetary Society keeping mum about the backers questions but trying their hardest to get people interested in space exploration and science.

    42. David Markland on June 13, 2017

      Two years, no centimeter of sail, no membership.

      I have to laugh - I got an email from the nice Mr. Nye yesterday imploring me to join the Planetary society for $50 dollars a year. Where is my membership from this fundraiser? How can they expect to raise money in the future when they have scammed so many?

      Andrew on May 16, 2017

      2 months ago, after a half a year of repeated attemtps, someone finlly responded to me. They told me my sail must have gotten lost in the mail and they would be happy to send another, and that my planetary society membership was active. This brings us to 2 days ago when I, having not yet recived this newly sent sail either, sent an email back to the person who indicated they where going to send me one right away 2 moths ago. They responded by telling me they couldnt send the sail and that i didn't have the membership, and that they had no clue when they would be able to get me either becuase their contractor is apparently still having issues cleaning up a few thousand records of bad data after over a year. Pathetic. How can we expect them to get a soalr sail into orbit, when they can't get a centimeter of it to someone that lives in the same county.

      William Thomas Etheredge IV on May 1, 2017

      A lot of us feel betrayed because we have not received the centimeter of sail. Really disappointed. I'm glad the light sails are being deployed though. Don't promise it if you can't deliver it, or apologize, something.

      If you try to raise funds with another Kickstarter campaign -- good luck.
