The MSL Jan 15th Teleconference

  Tuesday's JPL teleconference dealt with some of Curiosity's findings in the Yellowknife area over the last few weeks. The two most interesting items were some vein-filled material and some cross layering deposits. Chemical analysis indicates that the vein-filled material is most likely hydrated calcium sulfate that appears to have been left by water seeping through cracks in the rocks. The cross layering deposits with a variety of slopes are indicative of periodic water flows across the surface. Another discovery is a layer containing spherical objects which have been previously described as being formed in a water environment. Curiosity's plans include spending a few more days at the present location before it moves on to a nearby location dubbed John Klein where it will drill into the rocks there. They are also hoping to get a better view of the vein-filled material by breaking the rocks along a crack. After this Curiosity will move on to the lower reaches of Mt Sharp. telecon images & associated press release
