Curiouser and Curiouser: NASA's Curiousity Rover Finds Piles of Silica on Mars - by Bill Chappell/ America/ The Two-Way: Breaking News from NPR/ NPR/ npr.org
"In a finding that suggests "considerable water activity" on Mars, NASA says its Curiosity rover has found very high concentrations of silica on the red planet. The agency says it also found "a mineral named tridymite, rare on Earth and never seen before on Mars."
The discoveries took place on Mount Sharp, where Curiosity drilled into a rock called "Buckskin" to find the tridymite, and where it used its "ChemCam" laser to measure high silica levels. The odd findings led researchers to take the rare step of ordering Curiosity to retrace its path to learn more..."
After it drilled two holes in the "Buckskin" rock on Mars, the Curiosity rover took a series of photos that were turned into this panoramic self-portrait. The rover is sitting on the crest of a 20-foot hill.
