Curiosity Finds Evidence of Ancient Surface Water 79

An anonymous reader writes "Curiosity has wheeled its way over to the low point in Yellowknife Bay and has found veined rocks, evidence that water once percolated through this area. Scientists are excited because it is the first evidence of precipitation of minerals and water. There is also cross bedding that can be seen, thin layers of rocks oriented in different directions. The grains are apparently too coarse for the wind to have created, alluding to flowing water. Even with this discovery, much is still not known about Mars' past." Rather than quickly moving along to Mount Sharp as planned, they're going to spend some time drilling into the rock.

    "The grains are apparently too course for the wind to have created"

    Are they assuming Earth-like winds?

    Now that NASA has demonstrated that the rover technology in Curiosity works, why aren't we sending more of them up?

    The Skycrane landing had never been attempted before, but Curiosity landed intact. The analysis machines are working well, and are delivering good results from the rocks that are within 2 meters of the probe, but what about the rest of the planet? At the end of Curiosity's time on mars, we will have less than a square kilometer of the surface explored in detail.

    Why don't we send a few (dozen) more up to explore other valleys? This is like trying to figure out the Earth's geology by driving from Chicago to Gary, IN. (and only looking out the right side of the car)
