Mars Express Images of Olympus Mons

Posted by michael on from the skycam dept.

tr0llb4rt0 writes "The New Scientist reports on high resolution images of Olympus Mons taken by the ESA's Mars Express probe. Earlier pictures had suffered due to problems syncronizing the images from the high resolution stereo camera but these latest images are of excellent quality and scientists expect the quality of future images to improve further. High resolution images are available at the ESA's Mars Express Multimedia Gallery."

    I take it you've never been to Utah? And no, that's not a joke, the rock formations out there are breath-taking. Parts of Galaxy Quest were filmed there for that reason.

    Yes, a great many. We are certain (well, as certain as those things ever are) that "cold" (i.e., non-lava) flows shaped those features on Mars. AFAIK the only alternative under consideration to liquid water being responsible for those flows is mixed gaseous/liquid CO2.

    If you have some time to kill read these three articles. A very nice write-up of a lot of Mars science and theories.

    [Olympus Mons has] nearly 3 times as high as the Everest summit... less gravity to escape, less fuel to burn.

    The gravity at Olympus Mons is higher than average. Check out this gravity map of Mars. All of the black spots (the spots with the highest gravity) are volcanoes; the leftmost black spot on the left hemisphere is Olympus Mons.

    Gravity decreases as you get farther away from the surface, but when you're at the surface, it is the mass of the stuff under your feet that matters.
