Mars Pathfinder
Mission Objectives:

The primary objective was to demonstrate a low-cost method of delivering a set of science instruments and a free-ranging rover to the surface of Mars. The 23-pound Sojourner rover conducted technology experiments and served as an instrument deployment mechanism.

The science objectives were to:

  • Investigate the Martian atmosphere, surface metrology and geology
  • Characterize surface features
  • Analyze the elemental composition of rocks and soil at the landing site
  • Monitor atmospheric conditions as they varied over the course of the mission with photographic and analytical instruments
