First Controllable Solar Sail Launched Today 237

clustermonkey writes "The first controllable solar sail was launched earlier today from a Russian sub in the Barents Sea. The Planetary Society, founded by Carl Sagan, organized the project and were funded by Cosmos Studios, founded by Sagan's widow. There have been 2 other solar sail deployments by others, but this will be the first to attempt controlled flight. The sail is scheduled to deploy June 25." All may not be well, though: Snot Locker writes "The Cosmos 1 Weblog is showing that, although the launch initially looked successful, they can't seem to find it or hear it. Bummer. Previous Slashdot coverage on the Cosmos 1 Solar Sail mission can be found here."

    • Earlier today on Spaceflightnow (the quote seems to be gone in the current version of the story), the project leader was quoted as saying something like "there is a significant chance of failure". Similarly, the leader of the ill-fated Beagle 2 Mars lander publicly stated that he estimated the chances of success at about 50-50. I think we could all waste a lot less time if we just ignored missions whose own leaders inspire that much confidence. In space, you have zero tolerance for error, so what may see

    I really rather hope this project is okay and only suffering from a 'glitch'. (ie: unexpected orbit)

    The trouble is, every time you take what is essentially a robotically controlled device and send it into space giving it a good *shake* in the process (rockets really do vibrate a lot), you run the risk of breaking something.

    Of course, you combat this by duplicating as much of the systems as you can but when your experiment requires a very low mass (ala solar sail controller) I wonder how much redundancy is possible?

    Still. I hope Cosmos sparks back to life /is found and they get a sucessful experiment. I would be good to prove that solar-sailing is a viable solar-locomotion concept rather than just proving that electronics packages are fragile things.

      If you want to know what the people organizing the mission are thinking, the Planetary Society's Latest Update [] section is a good spot to go. As it stands, the following has been stated:

      * The signal didn't dissapear suddenly when the kick fired - it became irregular, and then dissapeared after three minutes.

      * The signal was received clearly after launch for six minutes.

      * There were irregular readings coming from the Volna; however, clearly the craft detached, or there wouldn't have been six minutes of signal.

      * STRATCOM can't find the satellite. That doesn't mean that it's gone - only that it's not where they told them to look. Likewise, the lack of ground station reception could mean the same thing. It could be in the wrong orbit, which is actually a more common phenominon than a total craft loss.

      * The chance of signal acquisition at the early two stations was only considered marginal to begin with. The big test will be at the permanent stations in Paska Ves, and especially the Tarusa and Bear lakes.

      * Not receiving a signal from a spacecraft during the first few orbits is "not extremely unusual". Nonetheless, they do sound a bit nervous.

      I know what really happened

      You see, the Russians never launched Cosmos 1, they realized that these guys would be a bunch of suckers so what they did, is they got them to pay for the launch, and then launched their own new spy satellite In the same orbit that Cosmos 1 was supposed to be in. And now they are going to tell them "tough luck, you must have out bad communications equipment on her or something". So the Americans pay the money, and the Russians get to launch their spy satellite.

    • No. Rockets don't accidentally escape into space--it takes way too much fuel. If it were that easy, the sail would have been sent on a trajectory away from earth.
    • It got high enough to burn up upon reentry, but not high enough to achieve orbit.

      That or it's simply not in its intended orbit, in which case reestablishing signal is a matter of finding the thing (which will happen eventually) so that one can figure out which way to point the groundstation antennas.

    • From the story:

      the first stage engine experienced "a spontaneous stoppage" 83 seconds into launch. The vehicle was allowed to continue flying because it lacked a destruct system. But there has been no further confirmation of the report.

      I just love that. The vehicle was "allowed" to continue to fly, because there's no way in hell they could stop it... Oops.

    PASADENA, California (Reuters) -- Cosmos 1, the first solar sail-powered spacecraft, appears to be "alive" and sending signals to tracking stations but could be in a lower orbit than planned, said mission experts in California, late on Tuesday.
    Telemetry data received by three tracking stations in the Pacific Ocean, Russia and the Czech Republic seemed to show that Cosmos 1 made it into orbit, mission staff at the Planetary Society said.
    Mission controllers discovered after reviewing telemetry data from the stations that the craft had signaled its passage during what had been believed to be several hours of radio silence, said Planetary Society co-founder Bruce Murray.
    "The good news is we have reason to believe it's alive and in orbit," Murray said. "The bad news is we don't know where it is."

    It's cheaper, and should provide continuous tracking and control anywhere.

    I think a standard INMARSAT-C terminal could be used for this purpose, as long as the local oscillator is replaced with a unit that uses the GPS signal to calculate the doppler vector to the satellite and apply a correction to the center frequency (Without doppler correction it would miss the 5kHz
