Sol 2706: Science team is go for drilling!

During the acquisition of the MAHLI images on Sol 2705, an arm issue prevented the sequence from completing.  But enough images were successfully acquired that it's not necessary to repeat the MAHLI sequence, and the arm fault is well understood so that no special recovery activities were required.

Active boulder movement at high Martian latitudes

Lobate stony landforms occur on steep slopes at high latitudes on Mars. We demonstrate active boulder movement at seven such sites. Sub-meter-scale boulders frequently move distances of a few meters. The movement is concentrated in the vicinity of the lobate landforms but also occurs on other slopes. This provides evidence for a new, common style...
