This is a map of the seasonal temperature changes of the south polar ice cap on Mars. It covers a four-month period.
This artist's rendition depicts the response of the solar wind to the planet Mars in it's path.
The supersonic (greater than that of sound) 'solar wind' consisting of electrically charged particles (ions and electrons) streams off the Sun into space.
It is slowed to subsonic speeds in the vicinity of Mars at a parabolic surface called a 'bow shock'.
Here, the magnetic field fluctuates wildly and the flow of the solar wind becomes chaotic. Part of the orbital trajectory of the Mars Global Surveyor is indicated.
This image shows the orientation and magnitude of the magnetic field at Mars. It was measured by the MGS magnetometer as it flew over the surface of Mars.
The vectors are drawn in the direction of the magnetic field measured at that point. The length of the line is scaled to show the relative magnitude of the field.
These maps are global false-color topographic views of Mars.
The picture at the right features the Hellas ( map of Mars ) impact basin (in purple/dark blue). The left hand features the Tharsis ( map of Mars ) topographic rise (in red and white).
Data for these data were compiled by the Mars Orbiter Laser Altimeter (MOLA). An altimeter is an instrument that measures height.
This is a simple schematic representation of localized magnetic sources in the crust of Mars, buried beneath the surface.
The data gathered via satellite reveal the presence of one or more magnetic anomalies close to the path of the spacecraft.
Scientists think that the crust of Mars is strewn with magnetic anomalies, awaiting discovery.
