Mars Express Images of Olympus Mons

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."

      Which means you have to burn a lot more fuel in order to slow down and stop, since you can't use aerobraking or parachutes.

      Being out of the atmosphere means you also have absolutely no protection against micrometeorites. On the flipside, you don't have to deal with dust or dust storms.

      How much less is the martian gravity? Can you land near the base of the mountain, get the astronauts to bring pieces of the return vehicle up to the top, and then launch from there? It's a lot easier hauling your ass up a hill than hauling your ass up thin air.

      >Being out of the atmosphere means you also have absolutely no protection against micrometeorites.

      Your return vehicle has to deal with that on the trip back, anyways.

      [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.

      If you could get enough speed (I would have to look up the laws to find out what speed), you would end up in an extremely low, and therefore unstable orbit, which would quickly degrade due to atmospheric friction (even at that altitude there would be enough), and you would crash. Not the most effective method of returning to Earth... (of course if you went even faster, you would reach escape velocity, but it would be much easier to go straight up, because you wouldn't need to keep the engines running so long)

      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.

    The top picture, while very cool and very accurate, is not actually a picture taken directly by the orbiter. Since they take stereo pictures, it is a straightforward task to recompute a new picture from a different angle.

    I've seen martian pictures done like this before, but always it was composites with different instruments, like MOC (Mars Orbital Camera) or THEMIS (Thermal Emission Imaging Spectrometer) to provide the visual component and MOLA (Mars Orbital Laser Altimeter) giving the third dimension data.

    Still, it's impressive as hell, and from a science standpoint will have geometric effect on the knowledge we've gained from the MGS and Odyssey orbiters. I hope Express has many years of good observations, and I look forward to ESA and NASA continuing the exploration of Mars. It's definitely a step in the right direction.
