Stardust Spacecraft Sends Home Close-Ups of a Comet

Well, NASA’s Valentine’s date seems to have gone off without a hitch. Last night the Stardust-NExT probe passed within 110 miles of the comet Tempel 1, and snapped plenty of pictures during its rendezvous. The mission’s main objective was to record the results of an experiment conducted by another spacecraft, Deep Impact, which hurled an impactor at Tempel 1 back in 2005. Researchers hoped Stardust would catch a glimpse of the man-made crater.

As Phil Plait writes:

The whole point here was to see the impact crater from 2005, and Stardust was able to do that. It’s difficult to see in these images here, but Pete Schultz, an impact specialist with the mission, said the crater is about 150 meters across and has a central peak, indicating material fell back to the comet. The crater wasn’t as obvious as expected, but is about the right size given the impactor speed, mass, and angle of impact.

Head over to Bad Astronomy for more details, and for a nice animation of the flyby.
