objectives

• 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
• Observe how the crater forms
• Measure the crater's depth and diameter
• Measure the composition of the interior of the
  crater and its ejecta
• Determine the changes in natural outgassing
  produced by the impact
