Mars Observer was an American robotic space probe launched by NASA on September 25, 1992, to study the surface, atmosphere, climate and magnetic field of Mars. The spacecraft was developed and managed by the Jet Propulsion Laboratory.
The project originated with a 1984 proposal for a new Mars mission, originally titled the Mars Geoscience Climatology Orbiter. As the first and ultimately only mission in the Planetary Observer program, its design was based on earlier Earth-orbiting satellites, including the TIROS and DMSP series. Seven scientific instruments were included.
