Mars - Mars Global Surveyor
Global view of Mars showing Valles Marineris and the south pole
This view of Mars was created by reconstructing imaging data
to correct for distortions and spacecraft motion. The image
gives an approximation of what Mars would look like through
a wide angle lens at an altitude of 2700 km over 30 S, 70 W.
At the top (north) of the image is Valles Marineris, the
system of canyons which stretches for over 4000 km. The
white area at the bottom of the image is the south polar cap.
The image covers about 100 degrees of longitude and latitude
with a resolution of 7.4 km. The hazy appearance is due to
dust in the atmosphere from a dust storm 3 weeks before the
image was taken. The image is false color, created from the
blue and red filtered wide angle camera.
