Deep Impact is closing in on its intended target-
This image is a compilation of 4 images that were taken on June 13, 2005, through the clear filter of the Medium Resolution Imager (MRI) camera. The spacecraft is 18,675,137.9 km (11,604,190 miles) away from comet Tempel 1, and the Sun is located to the right of the image.

Impact will occur between 05:49 and 5:55 UT July 4th or 5:52 +/- 3 minutes. You can chart the progress in multiple ways, but unfortunately we in North America will not be able to view the impact from our position on earth. I just spent some time at NASA's space simulator, where you can pick a target and date of various celestial bodies and spacecraft and it will give you a simulated picture.
