APL-Built Mineral-Mapping Imager Begins Mission at Mars
JHU/APL For Immediate Release September 27, 2006 See also A.J.S. Rayl's story at TPS. EDIT: I changed the topic title because, as I understand it from the press release, the cover was opened, not jettisoned. This post has been edited by AlexBlackwell: Sep 28 2006, 04:48 PM |

Recent article in Icarus:
Cloutis et al. Icarus 195 (2008) 140-168. "Spectral reflectance properties of minerals exposed to simulated Mars surface conditions." doi: 10.1016/j.icarus.2007.10.028. (pay-for article, Abstract available here) Lotsa mineral spectra. From skimming the article, it appears that for most minerals exposure to martian conditions doesn't drastically change the reflectance spectra. (The big exception was in some of the Fe(III) sulfates that did visibly change the color based on exposure time). So for the most part (and especially for carbonates, hydroxides, and hydrates), it means that the spectra you get on Earth are what you would expect on Mars. There is nothing "weird" going on.... -Mike -------------------- Some higher resolution images available at my photostream: http://www.flickr.com/photos/31678681@N07/
