    Not only are they launching a solar sail, just to make it even cooler, they are launching it from a submarine. I mean, how cool is that!

    Either that or this is a sneaky way to launch a pre-emptive nuclear strike with no-one suspecting until its too late.

    What if there is an eclipse?

    A solar eclipse would only affect the sail if it were still orbiting earth. In which case... just make sure you're not standing underneath it.

    I think that was the plan...to have it orbit Earth.  But, as of this morning, they really don't know where the sail is at...according to this article.

    The article wrote:
    Scientists who believe they may have detected signals from the world's first solar sail spacecraft say it could be hours or days before they figure out exactly where the $4 million Cosmos 1 is traveling.

    The signals were picked up shortly before 10 p.m. PDT Tuesday, hours after the spacecraft stopped communicating with mission controllers. Those communications had ceased soon after its launch from a Russian submarine under the Barrents Sea.

    Elaborate made up conspiracy theory time!

    Really, this was a plot to Nuke North Korea. Anyone heard anything from North Korea since this happened? No, didnt think so. So the plot was to pretend they were launching a satalite from a sub. All very feasible - no one pay any attention, this isnt a nuclear warhead its satalite. But really, it WAS a missile and now the north koreans glow!

    Hey, whats that black van doing in the car park?

    Sadly the Solar Sail failed. Credit to W3bbo for telling me.

    Not necessarily.

    "We have no evidence that anything is wrong with the spacecraft at all," said Bruce Betts, the Planetary Society's director of projects, late on Tuesday.


    But there were conflicting reports. Russia's Itar-Tass and Interfax news agencies quoted an unnamed Russian space agency source as saying that the craft had crashed near a remote island in the Barents Sea close to where it had been launched.

    Ironically, if you jump around the links in this thread, you'll notice that the failure is always the Russian piece of equipment, be it the launch platform or the booster mechanism. Kind of funny!

    Hmmmm, I wonder who makes the OS that runs the flight mechanics?  Is it analog or software?

    Ain't that a shame.
