How freakin' cool is this: NASA has a Quicktime movie taken by the impactor that was sent to crash into the comet Temple 1 as it was crashing into the comet. Actually, the comet was crashing into the impactor, but let's not quibble. What we have here is a real movie of an object smacking into a comet - not some sci-fi movie CGI. We may forget in this era of Star Wars, Episode Bajillion that this kind of thing was absolutely unimaginable not long ago. We may not take a moment to really think about the precise science and vast speeds and distances involved because it makes our brains hurt. But check this out and see if it doesn't make you a little bit more impressed with human beigns, despite all our aggravating faults.
Here's the movie.
