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
