Summary

Blasting a comet for science's sake turns out to be harder than expected, but targeting Tempel 1 has revealed a fragile body that's already been through geologic turmoil. The Deep Impact team members report online in Science this week (see www.sciencemag.org/cgi/content/abstract/1118978, www.sciencemag.org/cgi/content/abstract/1119020, and www.sciencemag.org/cgi/content/abstract/1118923) that the impact blew out so much unexpectedly fine powder that they still haven't seen the crater through all the dust.
