Here are some press releases with photos:
http://www.uanews.org/story/ua-mars-camera-reveals-hundreds-of-impacts-each-year http://www.jpl.nasa.gov/news/news.php?release=2013-162 The paper itself is behind a paywall: http://www.sciencedirect.com/science/article/pii/S0019103513001693 Over these photos there is quite a range of colors in the undisturbed surface, the colour of the craters and the colour of surface where the ejected material has landed. I get the impression that Mars would be not such a great place to find meteorites. It seems that few of them would be slowed enough by the atmosphere to land at a moderate speed. Gravity is about 0.37 that of Earth's and the surface pressure is 0.006. Although the scale height is 1.8 times that of Earth's, I guess that the only meteorites which fall to the surface slow enough to survive would be a lot smaller than those which can do this on Earth. Perhaps a few fragments of exploding larger objects might cool and fall this way, but my impression is that Earth would have more meteorites remaining intact on or somewhat impacted into the surface than would be the case on Mars. - Robin ______________________________________________ Visit the Archives at http://www.meteorite-list-archives.com Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list
