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."
Collecting rocks on mars is nice and all, but can we work towards bigger goals such as establishing a permenant base somewhere not on earth? Learning about rocks on mars may help us learn about planet formations but can't we do that once we have a foothold there?
All you need to do is look at what they're doing to Curiosity's mission planning (they're still not at Mt. Sharp yet because of detours) to see how well the Mars 2020 mission is going to accomplish its primary science objectives. Igneous rock is going to be a tall order for a rover to investigate because it is A) harder than steel (the drill on Curiosity would have a tough time even scratching it) and B) sharper too (Curiosity's wheels are easily damaged by sharp rocks).
To top all this off there really really isn't much mass budget or volume leeway for improvements based on what we learned from Curiosity.
Hopefully they will fix the wheels for the next rover before sending it. Otherwise seems like a waste of rapidly dwindling plutonium.
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.
is a sty that is getting worser and worserer. Everybody know that pigs live in sties. Not extremophilic microbes. Doh.

Targeting extremophilic deposits assumes that life on Mars, if it ever existed, really did or colonize start volcanic pipes or underwater vents. This is a big assumption.
I'm all in favor of spending money on space exploration, but the way I see it, Mars represents a point of diminishing returns. In the true spirit of exploration, we should begin looking at other interesting environments, such as drilling into Europa or Enceladus. This obsessive focus on Mars is a boon for Mars experts, but it has a real cost in terms delayed progress towards understanding other solar system and deep space targets.
Space exploration missions will inspire audiences and yield side-benefits no matter where they go. Why not spread what little wealth there is and look towards bolder, more exciting targets?
Here's another well-argued perspective on my point:

As opposed to your evidence-free and rather hilarious life-by-magic that's supposed to be a world-wide thing even though in areas without prior contact there's no concept of it?
