Quote:The photo caption calls them "light-toned" as well as "bright" particles. That seems to me the better description.I'm going to go out on a limb and make a guess...Hydrated silica, or "opal".There are a lot of other possibilities, so I'm not going to stand on it. But looking at the fact that some of these lighter particles have a nodular structure, some kind of fluid-based concretion seems plausible to me.

Quote:The band of radiation that is being measured and plotted must not include solar UV or other solar components that have diurnal change independent of air density. I think the main point is that cooler night air is denser and offers more shielding. The radiation band measured and plotted may be only a small portion of the total radiation reaching Curiousity from sun, cosmic rays and maybe even low level emission from Mars rocks at landing site.
