The Mars Global
Surveyor (MGS) spacecraft has now circled the Red Planet during two successive
centuries, 1997 to 2003 and has redefined our knowledge of Mars' surface,
atmosphere, interior, and history. MGS has returned more data about the red
planet than all other Mars missions combined and has produced the most accurate
global topographic map of any planet in the solar system. Some of the spacecraft's
key findings include the revelation of gullies and debris-flow features that
suggest current sources of liquid water, similar to an aquifer, at or near
the surface of the planet. The spacecraft has also significantly improved
the understanding of atmospheric dynamics. As the next Mars rover mission
is prepared for launch, the accomplishments of the Mars Global Surveyor Spacecraft
and its science teams give us perspective on where we are going.
