How about a story showing a gold rush on a near-future colony of Mars? Terri Main publishes a paper called " Science news for Sci-Fi writers ," in which today I saw a link leading to an article from Io9 that shows a photo I'm including below: This photo shows dry ice pits common in the southern hemisphere of Mars, a planet cold enough to fill these pits every Martian-southern-hemisphere-winter with frozen solid carbon dioxide from the Martian atmosphere. Every summer, some of the frozen CO2 (a.k.a. dry ice) melts away, revealing these pits with curious shiny gold rims. (For scale, the small one in the center is about 200 feet across.) It so happens that as of now, no Earthly scientist knows what the causes the gold-coloring around these pits.
