Mars Global Surveyor is a global mapping mission, examining the entire planet - from the ionosphere (an envelope of charged particles surrounding Mars) down through the atmosphere to the surface, and deep into Mars' interior. As part of the larger Mars Exploration Program, Mars Global Surveyor performs atmospheric monitoring for sister orbiters during aerobraking, and it helps rovers and lander missions by identifying potential landing sites and relaying surface telemetry.

Goals: Mars Global Surveyor contributes to meeting the four main science goals of the Mars Exploration Program:

Goal 1 image Determine whether life ever arose on Mars
Goal 2 image Characterize the climate of Mars
Goal 3 image Characterize the geology of Mars
Goal 4 image Prepare for human exploration


Objectives: Learn about Mars Global Surveyor's unique contributions to these science goals through its science objectives.

Science Instruments: For a description of how Mars Global Surveyor collects data in support of these goals and objectives, please see the science instruments in the Mission Section.

Scientific Data: Mars Global Surveyor scientific data are available from two websites.

Point the Camera: Suggest a target on Mars for the camera on Mars Global Surveyor through the Public Target Request Site managed by Malin Space Science Systems.
