The '''Planetary Observer program''' is a cancelled [[space exploration]] program designed by [[NASA]] to provide cheaper planetary orbiters by using Earth-orbiting satellite components and technology, using solar panels for power, and a common spacecraft bus platform for all Planetary Observer-class probes. Only one spacecraft of this class was eventually constructed—the ''[[Mars Observer]]''.<ref>{{Cite news |url=https://www.deseret.com/1992/11/6/19014815/nasa-picks-basic-spaceship-over-awesome-alternative/ |agency=Associated Press |title=NASA Picks Basic Spaceship Over Awesome Alternative |publisher=The Deseret News |date=November 6, 1992}}</ref><ref>Peter J.
