TL;DR: A large increase in organic material occurred during and after the event, with smaller changes in carbon dioxide relative to water, and a thermal map indicates a surface in equilibrium with sunlight.

TL;DR: The direct detection of solid water ice deposits exposed on the surface of comet 9P/Tempel 1, as observed by the Deep Impact mission, suggests that the surface deposits are loose aggregates.
Journal ArticleDOI

Olivier Groussin,Michael F. A'Hearn,Jian-Yang Li,Peter C. Thomas,Jessica M. Sunshine,Carey M. Lisse,Karen J. Meech,Tony L. Farnham,Lori M. Feaga,W. A. Delamere +9 more
TL;DR: The Deep Impact (DI) spacecraft encountered Comet 9P/Tempel 1 on July 4th, 2005 and observed it with several instruments, including the HRI-IR spectrometer in the wavelength range of 1.0-4.9 μm as discussed by the authors.
