    Hocus Eye. Snap, crop, scrap crap

    I find this fascinating stuff. There are some interesting short PDF documents on that site containing more information and images of the Rosetta mission.

    Balbi Hey, Dean Yager!

    Is it possible to transmit a cup of coffee out there, sounds like Rosetta needs it.

    About half-way through the expected window.

    Not a peep yet.

    They're getting restless in the operations room.

    A large espresso might have been a good idea.

    Maurice Picarda Actually, might as well flounce.

    Seems to have. Nice that it's made them all so happy, even though the coverage is a trifle Eurovision.

    Animation of the approach and orbit of the comet (scheduled for November)

    http://www.esa.int/spaceinvideos/Videos/2014/01/Rosetta_s_orbit_around_the_comet

    What you're seeing:

    The "triangular" phase is not an orbit as such. The comet is only 4km wide so has very slight gravity, so this phase is more like "falling" slowly towards it, whilst manoeuvring around to get a good view. Then it comes in for a 30km radius polar orbit to build up a map of the comet's surface. Finally it comes in closer for the 12km orbit that it will sit in for the rest of the mission. At all times the orbit is kept clear of the sun-shaded side, as that is where the coma (the comet's tail) forms, full of dust and ice that could damage the spacecraft.

    I can't believe they're actually going to *land* a smaller probe on the comet itself. It's an amazing mission.

    It looks more like a chess piece to me. A giant chess piece hurtling through space. :hmm:

    It's about the size of central London, to give it some scale, from Park Lane to the Tower, Euston Road to the River.
