Portion of Earth Facing Spacecraft Encounter with Tempel 1
This is the side of Earth that will "see" the comet at impact. Unfortunately, even though the comet is above the horizon for observers in Australia, it is still daylight and they will have to wait for dark. Look to the upper right and you can just make out the West Coast of the United States. Of course, we won't know what the cloud cover will be like that day. This is just a simulation from the Solar System Simulator.
