    Very excited by this.

    I hope this pioneers missions to Jupiter outer moons and hopefully one day we will send manned missions there.

    If cyrovulcanisim can exist on an asteroid in the middle of nowhere, then the chances of life a much much higher on the moons and asteroids than anyone could have realized.

    I love unexpected mysteries. Everytime we look, we find something we didn't even predict.

    Haha doesn't seem very jerky to me - looks awesome!!! :D

    The bright spot in the crater definitely seems like some kind of ejecta / raised area. Very interesting.

    I also can't wait for New Horizons data to start coming in :Pirate:

    IMO the bright spots are cyrovolcanism. But then that raises the question what the hell is causing it. You basically have liquid water (well sort of) bubbling out on a surface on something not that far away from earth, that isn't bathed in deadly radiation and we haven't yet sent a probe there.

    Imagine a geyser on the Moon or Mars, we would be all over it. Here we have dozens of them, and we haven't even taken a good look for it yet. Basically any bacteria that lives in Antartica could make for a good life on Ceres.

    If I was an Alien. Ceres would be the most liveable and nices place other than Earth. I would put it ahead of the Moon and Mars and Europa. I would be setting my human observation post on Ceres.

    New Horizons should be pretty cool, So much happening this year. New Horizons will just be a short event, where I am hoping Dawn, will trickle interesting stuff for years.

    Images should be spectacularly good. I can't wait to see what Dawn produces when its 1000 times closer than it is now.

    I;m not holding out for little green men, but even bacteria or similar would show without doubt that there is life elsewhere than this little ball we are spinning on.

    Mystery of bright spots on Ceres grows.

    Other unusual properties include it's a different colour to the other asteroids close by and it has less large impact craters.

    IMO Ceres seems to be one interesting place.

    Wonder why spot 5 the brightest, doesn't show up in IR.

    Ah, New Horizons. I got my name on that spacecraft. Closest ever Pluto flyby scheduled for July 14.

    Bloody unreal!

    how do they control these craft? Is it all to do with gravity around surrounding bodies?

    Much of it. They have hydrazine thrusters some now have ion propulsion

    It ain't like dusting crops, boy! Without precise calculations they could fly right through a star or bounce too close to a supernova, and that'd end their trip real quick, wouldn't it.
