Mars - Mars Global Surveyor

Global view of Mars showing Valles Marineris and the south pole

Mars
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. (Mars Global Surveyor, MRPS86906)
