SUMMARY: Researchers have had a few months to crunch through the data collected during Deep Impact's collision with Comet Tempel 1. The latest research published in the Journal Science used findings from three giant telescopes atop Mauna Kea in Hawaii. The observations determined that as much as 25 fully-loaded tractor trailer-trucks worth of material was excavated out by the impact. The comet seems to have a complex mix of silicates, water and organic compounds beneath its surface.

I'm glad to see more of the observations about this impact coming out. The first things we saw indicated that little water was blasted out, but now we are starting to see observations of water, which seems more like the kind of thing we were expecting.

This last week I've read several articles on the comet Temple1 - one mentioned having found olivine - an element found in close contact with water at some stage. It appears as a kind of green sand & can be found in the Hawaian Islands as well as on Mars & Temple1!
