The Deep Impact mission aimed to study comet Tempel 1 by crashing an impactor spacecraft into its surface. The flyby spacecraft would observe the impact and study the crater formation and ejecta plume. The impactor was the size of a coffee table while the flyby spacecraft was nearly the size of a Volkswagen Beetle. The impact was scheduled for July 4, 2005 at a velocity of 23,000 mph to excavate a crater over 100 meters in diameter and expose the comet's pristine interior for analysis.

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
