Photo: BloombergWashington: Nasa’s Mars rover has beamed back images of an ancient valley that may have been carved by flowing water on the inner slope of a vast crater’s rim. The process that carved Perseverance Valley into the rim of Endeavour Crater billions of years ago has not yet been identified. The upper end of the valley is at a broad notch in the crest of the crater rim. “We expect to do a little walkabout just outside the crater before driving down Perseverance Valley,” Golombek said.
