NASA Looks To Volcanic Rocks As Target For Next Mars Rover
sciencehabit (1205606) writes "At a 3-day workshop, planetary scientists advocated for igneous rock–bearing landing sites as high-priority targets for NASA's next Mars rover mission, scheduled to launch in 2020. The $1.5 billion rover, a near-copy of the Curiosity rover, will collect about 30 samples of rock and soil for eventual return to Earth. Mineralized fracture zones at such sties may have been home at one time hydrothermal systems, with hot, fluid-filled fractures. Hydrothermal sites on Earth harbor ecosystems with extremophilic microbes."
I think that the current MSL rover is doing the right thing, searching for lake-bottom sediments and not rusing to the base of Mt. Sharp like the non-scientists in the Media seem so keen on. Searching for extremophiles is fine, but not at the expense of more missions to study water-borne sediments. Vallis Mawrth and other sites beckon.
