Mars: August 2015

Toiling in barren rock fields in southern Spain under temperatures as high as 108 degrees Fahrenheit, a team from NASA's Ames Research Center, Honeybee Robotics, and Spain's Centro de Astrobiologia (CAB, INTA-CSIC) is changing dirt into data in a way that could one day be replicated on Mars.

Mars turned cold and dry long ago, but researchers at the University of Colorado Boulder have discovered evidence of an ancient lake that likely represents some of the last potentially habitable surface water ever to exist on the Red Planet.
