New Findings from Curiosity Hint Ancient Mars Lake 'Favorable for Different Microbial Life'

Mudstone lakebed sedimentary deposits seen by the Curiosity rover in Gale crater. The latest findings show that the lake in the crater was stratified and could have supported a wide variety of microorganisms. Photo Credit: NASA/JPL-Caltech

Was Mars ever habitable? Did life ever actually exist there? Those are two of the biggest questions for […]

A Martian Paradox: Curiosity Rover Findings Raise New Questions About Water on Ancient Mars

View from Curiosity of the Yellowknife Bay rock formation. Drilled samples here and elsewhere provided evidence that this region used to be at the bottom of a lake, but also that there are little or no carbonate mineral deposits, which should have been produced if the carbon dioxide atmosphere was thicker and warmer billions […]
