Mars Global Surveyor (MGS), United States spacecraft launched toward the planet Mars in 1996, the first in a series of small U.S. spacecraft that the National Aeronautics and Space Administration (NASA) has launched toward Mars. Mars Global Surveyor was designed to provide an overview of the planet to prepare for future Mars exploration missions. From 1999 to 2006, MGS studied Marsís surface and atmosphere and used measurements of the planetís gravitational force and magnetism to study its internal structure. The space probe went silent in November 2006 after functioning well past its planned two-year mission.
