Mars Global Surveyor has been orbiting the red planet since Sept. 12, 1997. The mission has examined the entire Mars surface and provided a wealth of information about the planet’s atmosphere and interior. A new batch of high resolution photos, taken between February and July 2002, were added online this month and they bring the total number of images in the online gallery to more than 123,800. The images are available from the Mars Orbiter Camera Gallery.
