NASA distributed recent pictures, taken by Mars explorer Spirit, on the red planet which news reports are speculating could be a sign of life on the planet. The photo, they say, depicts a female figure walking down a mountain swinging her arm. How they know the figure is female beats me, and without a sequence of images it's really difficult to believe that there's any movement of the figure. For all I know it could be a bizarre geological feature of the planet that creates such sculpted figures. Perhaps Henry Moore left something behind in a recent visit.
