More Evidence for a Wetter, “Volcanier” Mars

Spirit may have settled in for an eternal sleep on Mars but the data she’s sent back is still helping researchers piece together clues for a wetter history of the red planet!

The image above, a false-color view from the “Home Plate” region where Spirit now sits,  points to a feature geologists call a “bomb sag”. Bombs are rocks ejected from volcanic eruptions, and a sag is the crater that’s formed when said rocks impact the ground. A team of researchers from the University of California at Berkeley used this photographic evidence to recreate what the conditions of Mars’ air and soil may have been like during the time of the bomb sag’s formation.

What did they find? Read the rest of this article on National Geographic Newswatch.
