1. Comet Impact:
July 4, 2005
Impact Velocity:
23,000 mph
Spacecraft Size:
Flyby spacecraft nearly as large as a
Volkswagen Beetle
automobile.
Impactor spacecraft about the same
dimensions as a
typical living room
coffee table.

2. Principal Investigator, Dr. Michael A'Hearn and his
science team want to find clues to the formation
of the solar system and more about the structure
and composition of comets by making a deep
crater in Comet Tempel 1. The objectives for the
mission are:
1. Observe how the crater forms
2. Measure the crater's depth and diameter
3. Measure the composition of the interior of the
crater and its ejecta
4. Determine the changes in natural outgassing
produced by the impact
Science Objective
