Deep Impact: Observations from a worldwide Earth-based campaign
Abbreviated Journal Title

On 4 July 2005, many observatories around the world and in space observed the collision of Deep Impact with comet 9P/Tempet 1 or its aftermath. This was an unprecedented coordinated observational campaign. These data show that (i) there was new material after impact that was compositionally different from that seen before impact; (ii) the ratio of dust mass to gas mass in the ejecta was much larger than before impact; (iii) the new activity did not last more than a few days, and by 9 July the comet's behavior was indistinguishable from its pre-impact behavior; and (iv) there were interesting transient phenomena that may be correlated with cratering physics.
