    Deep Impact continues to hurtle toward comet Tempel 1. Impact with the comet is scheduled for 1:52 a.m. EDT, July 4.

    Here's a couple of quick photos:


    This ia a picture of comet Tempel 1 taken by the Deep Impact probe's impactor targeting sensor. The probe collided with the comet at at 10:52 p.m. Pacific time, July 3


    Images from the the impactor targeting sensor aboard Deep Impact's impactor spacecraft were used to create this movie of impact with Tempel 1.


    This image of Tempel 1 was taken by the impactor targeting sensor aboard the impactor spacecraft shortly before impact.

    For the latest news and photos as they occur, visit: http://www.nasa.gov/mission_pages/de...ain/index.html

    Hopefully, they'll post some data from the flyby spacecraft.

    That is quite an impact. NASA knew everything that happened just like they planned

    yea cool stuff! seems this isnt the first time Tempel was hit by something. On Skinwalkers' second picture you can clearly see a number of impact-craters.

    I wonder why they couldn't land a craft like they did on Mars to examine the asteroid better than by just hitting it? Perhaps there's not enough gravity?

    This mission was about examining the layers that make up a comet. Blasting a big hole in it is an effective and cheap way to do this. The Rosetta mission by ESA will orbit and put a lander on comet 67 P/Churyumov-Gerasimenko. The spacecraft was launched in 2004 and will arrive in 2014:

    Well then why not send the first to blast the hole then a second one to land and take samples as well? It would seem odd that while they had a chance to send a rover there they didn't and we have to wait that much longer to find out more about asteroids with a rover. I very glad they did do so well but it could have been far better...IMHO.

    Cheaper?? I don't think so, it would be cheaper to land it...cause then you dont kill the thing...you can use it for ferther observations...

    Deep Impact is a Discovery class mission and thus has a very limited budget.

    Every mission could have been far better. You just need need to spend enough money. The Mars Rovers at $ 500 million each are great but the 2009 MSL costing $ +1 billion will be much better. It's just a matter of budget, you can't do everything you want. No matter how large your budget is an even bigger budget will buy you an even better spacecraft.

    An impactor is much simpler to design than a lander. Also building cost will be less. Using it for further observation will only make it more expensive. You need to pay the scientists and for the time on the DSN after all.
