YAY!! Thank you anonymous donator!!
I'm glad has grown up a bit, is bigger, and we'll all be around to enjoy this - it's a special project in so many ways. |

I was wondering what they were about to announce, and for me this is the best announcement they could possibly have made. As a planetary society member but not a millionnaire I have to choose carefully between the many good projects for which they solicit contributions. This is the one towards which my unavoidably modest contribution was the most heartfelt. The technology will be elegant and clean, yet the scope of imagination and ambition that lies behind it is truly breathtaking. I hope this time their diamond in the sky will fly - and inspire millions young and old as it should.

What a way to commemorate the late Dr Carl Sagan... who's more beloved nowadays than ever before!
Deploying the solar sail will be the hardest bit of the mission, so all the best to the mission! |

Nice little article on Reuters....go, TPS, go, LightSail!!!!

There's a longer article in the New York Times, with some nice graphics. There's also an interesting -- but extremely negative -- comment from a reader who says he worked on solar sails at jpl and claims that the experiment won't show anything.

Not necessarily a bad thing. Thoughful technical criticism is valuable regardless of the source, and this is free to boot! Nobody ever sees all aspects of an issue, which is one reason why systems engineering was invented.

"humans may soon be solar-sailing".
Who on Earth can create such a stupid misleading comment for an artists impression ? |

Depends on your definition of "soon".
Given new developments in materials technology, radiation protection technology, and space habitation technology I could imagine lofting up a self-supporting station using a massive (multi-thousand km) solar sail for a long voyage. But I think we're still a few generations off....(but I'd love to be proved wrong.) (Fun fact: the entire Wright brothers flight could have occured inside a Boeing 747. Could the general public have imagined a 400 person passenger jet routinely traversing the Pacific at 37,000 feet back in the late 1800's?)

Also depends on what you mean by 'solar sailing'. After all you can fly a kite or sail a model boat without being on board. My gripe is with the artwork itself. It appears to show a wrinkly surface on the sail panels yet the Earth's reflection is not broken up accordingly. Fortunately both the artwork and the caption pale into insignificance beside the fact that the project is going ahead.

Re: "humans may soon be solar-sailing"
The illustration is of the very light sail that the Planetary Society hopes to fly by 2011. So, yes, the humans at the Planetary Society will hopefully be solar-sailing soon. Vicariously to be sure. By the way, google the artist, he seems quite accomplished. "LightSail-1 will have four triangular sails, arranged in a diamond shape resembling a giant kite.... We plan to design, develop, build and test the LightSail-1 spacecraft so that it can be ready for launch by the end of 2010." Artists rendition of LightSail-1 by Rick Sternbach.

I will say - having tried in the past a bit - doing animations of stuff like reflective foil in deep space - it's a big challenge.

My gripe is with the artwork itself. It appears to show a wrinkly surface on the sail panels yet the Earth's reflection is not broken up accordingly. I thought about crackling up the Earth reflection a bit more, but I decided that most folks would have fixated on the unevenness of the reflection and not seen the bigger picture, so to speak. Sometimes complete photographic reality in art is not the best way to go. Rick |

Sometimes complete photographic reality in art is not the best way to go. No gripe with that statement at all. As an artist you are free. My comment arose from the fact that when looking at that particular image and wanting to 'enter the scene' I found myself distracted by the apparent incongruity. But it's all subjective at the viewer's end too and maybe I'm in a minority of one! At any rate I'm (of late) merely an enthusiast for space art whereas you're actually creating it, so count me as a fan. |

Your lens flare useage is a diagnosable psychiatric condition . Rick's use of artistic licence is entirely normal

At any rate I'm (of late) merely an enthusiast for space art whereas you're actually creating it, so count me as a fan. And I have no gripe with your gripe. If there weren't any discussion about things, it would all be pretty boring. A good deal of the space art we do takes liberties with light levels and colors and so on, to make it more accessible, and there's a sliding scale of what is "correct" that runs all the way to total photographic realism, particularly in scientific visualization. Not counting, of course, the horribly gaudy 20X vertical representations of Venus from years back. And Stu, I do like a -teeny- bit of lens flare now and then (it can be such an overused gimmick), or some subtle play of light that guides the eye to a certain point. Not like in a certain recent movie. Rick |

I'm curious if the camera's that were shown in the video are off-the-shelf, or were they designed specifically for the mission of LightSail-1? If they are off-the-shelf, who manufactured the camera's and optics?

The article below mentions three upcoming NASA missions (which will be flown on the venerable Delta 2 rocket) that would reach orbital altitudes that seem desirable for Lightsail-1...which The Planetary Society wants to send to an altitude of 800 km (500 miles):
http://www.spaceflightnow.com/news/n1207/16delta2/ OCO 2 (launch in 2014): 438-mile polar orbit SMAP (launch in 2014): 423 miles above Earth JPSS 1 (launch in 2016): 512 miles above Earth Of course, I think TPS is planning to launch Lightsail-1 before the end of this year...so all of this may be a moot point -------------------- 2011 JPL Tweetup photos: http://www.rich-parno.com/aa_jpltweetup.html

Nice!
LightSail Sails through Day-in-the-Life Test While there is still much work to be done before the team decides whether or not to send LightSail-A on a 2015 shakedown flight, Tuesday’s test sent the spacecraft over a big project hurdle—and gave the team a much-needed morale boost. http://www.planetary.org/blogs/jason-davis...sails-ditl.html -------------------- 2011 JPL Tweetup photos: http://www.rich-parno.com/aa_jpltweetup.html

LightSail Completes Testing, Announcement Expected in January
LightSail has now been transferred to Cal Poly. The spacecraft will be integrated with its P-POD (Pico-PolySat Orbital Deployer) in mid-January. An announcement from The Planetary Society on the status of the 2015 test flight is expected around the same time. Following P-POD integration, the spacecraft will be taken to the Naval Postgraduate School in Monterey, Calif. for final acceptance testing. http://www.planetary.org/blogs/jason-davis...es-testing.html -------------------- 2011 JPL Tweetup photos: http://www.rich-parno.com/aa_jpltweetup.html

Wondering if anybody here can do better than I did at descrambling the partial picture of LightSail that we received today. Hopefully the full image will be transmitted eventually, so it might be wasted effort. But it was a fun jigsaw puzzle to attempt

For anyone not already following, the complete version is now posted at Lightsail Mission Control. Huge congratulations to the team who it must be said have had to perform technical and mental acrobatics just to stay in the saddle. They will be hoping the voyage of lightsail-2 is equally inspirational but a lot less hectic.
