This image released by NASA 26 June, 2001 shows Mars from pole to pole and east to west. The picture was digitally reconstructed from over 200 million laser altimeter measurements taken by the Mars Global Surveyor spacecraft currently orbiting Mars. The image strips Mars of its clouds and dust, and renders the whole surface visible simultaneously in its true daytime color. Particularly notable are the volcanoes of the Tharsis province, visible on the left, which are taller than any mountains on Earth. Just to the left of center is Valles Marineris, a canyon much longer and deeper Earth's Grand Canyon. On the right, south of the center, is the Hellas Planitia, a basin over 2000 kilometers wide that waslikely created by a collision with an asteroid. (KEYSTONE/EPA PHOTO/NASA/STR)
