Prior to the selection of the comet 9P/Tempel 1 as the Deep Impact mission target the comet was not well observed. From 1999 through the present there has been an intensive world wide observing campaign designed to obtain mission critical information. The Deep Impact mission is unique in that part of the mission observations will rely on Earth based suite of complementary observations of the comet just prior to impact and in the weeks following. The impact would result in new cometary activity, the actual physical outcome is uncertain, and the Earth based observations must allow for awide range of post-impact phenomena. The world wide coordinated efforts for getting these observations has been discussed.
