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 |

Good article on clay identification on Mars using CRISM:
http://www.space.com/searchforlife/080320-...mars-water.html And Figure 1A-C (here.) is an excellent example of how to use spectral information to identify clay minerals. This is the key to the clay groups and spectral line colors in Figure 1A-B: blue = Al-phyllosilicate orange = Fe/Mg-smectite green = the hydrated silica/mica (Look carefully at the subtle differences in the valleys near 1.9 um, 2.2 um and 2.3 um for the different minerals. I had to stare at it for a few minutes before I saw the differences.) -Mike -------------------- Some higher resolution images available at my photostream: http://www.flickr.com/photos/31678681@N07/
