After driving over some rocks on Mars, the Curiosity rover has discovered an abundance of pure sulfur inside the crushed rocks.
The six-wheeled rover has spotted sulfur on Mars before, but only in a mixture with other minerals, including magnesium and calcium. Pure sulfur, an odorless element that forms in very specific conditions that planetary scientists hadn't linked to the rover's location, appears to be infused in many rocks across the region, according to NASA.
"It shouldn't be there, so now we have to explain it."
