    well, this makes me feel more at peace. we can definitely blow up any rogue comet with nukes if it threatens earth. awesome. and we probably wouldn't have to risk any real people, just probes and droids and stuff.



    bwah ha hah haha hahaha ha hha




    I believe disaster movies have made it clear that any effort to blow up a comet or asteroid just breaks it up into chunks that will do even more damage, and that in fact our only real hope lies in a fast track mission of an ad hoc team of lovable, wisecracking misfits who will leave one of their members behind.



    Oh wait, I'm thinking of how you fix social security......

    The problem is seeing some of these things before they hit. Even in the last few decades there has been a few rocks that came and went before we even realized it. We need to have more searches going on. Bravo to NASA they did a great job on this one. Now if we can just get a cheap and safe way to low earth orbit we will be on our way.

    Why are there never any stars in these types of pictures? I know hollywood jacks up the star size and count to look cooler but NASA shit is all pitch black space and not at all like what I can see from the ground (which is a ton of stars).



    I understand exposures etc. but even the handheld videocameras on the shuttles, when auto adjusting exposures as they moved, never show a hint of stars.

    1 there are more stars then hollywood uses and 2 the bright object overpowers any hint of a star background, its like looking into the sun. Thanks curiussuburb for the quicktime link.

    In some cases, they've filtered the image to subtract stars, because depending on mission, that's not what they're interested in and they can get more precise imaging of the real target with special processing.



    In the majority of other cases, it's mostly a matter of sensitivity and exposure.

    Flyby Spacecraft offers first movies of impact.



    Still in need of processing to clean up the images, but even the preliminary shows an epic smack.



    (note that the actual movies are smaller res than the blowup stills linked below.



    Medium Resolution Camera

    Click for QT Movie



    High Resolution Camera

    Click for QT Movie



    Impressive!

    good stuff. stellar, if i may say so (pun intended)



    you do know that all the 3d and visual effects artists are just creaming themselves over all this stuff, mainly because they're getting NASA 'reference' footage for a lot of their work.



    from a visual effects perspective, three things stand out



    1. the camera is able to resolve all the comet 'halo' away and just focus on the nucleus, which looks like an asteroid



    2. a lot of surface texture, not much geysers and debris being ejected from the nucleus, even for the 'sun side' of the comet



    3. totally unlike the movies Deep Impact and Armageddon there is apparently no fancy flying required by han solo - type hotshot pilots on approach to the surface, mainly because of IMHO see point 2. above





    hmmmm
