|Title:||Deep Impact: excavating comet 9P/Tempel 1|
|Authors:||A'Hearn, M. F.|
|Publication:||Asteroids, Comets, Meteors, Proceedings of the 229th Symposium of the International Astronomical Union held in Búzios, Rio de Janeiro, Brasil August 7-12, 2005, Edited by D. Lazzaro, S. Ferraz-Mello & J.A. Fernández. Cambridge: Cambridge University Press, 2006., pp.33-40|
The Deep Impact mission delivered 19 gigajoules of kinetic energy to the
nucleus of comet 9P/Tempel 1 on 4 July 2005. Intensive observations,
both from the two spacecraft and from Earth and Earth-orbit, while
approaching the comet led to numerous new findings about comets.
Observations of the impact event, from the flyby spacecraft have led us
to a determination of numerous physical properties of the nucleus.
Analysis of the near-IR spectra is still very preliminary.
