NASA's Curiosity Mars rover has accidentally uncovered an abundance of never-before-seen crystals on the Red Planet after inadvertently running over a rock.
On May 30, the rover was exploring Gediz Vallis — a channel carved into the steep slopes of Mount Sharp in the heart of Gale Crater — when it accidentally drove over a small rock, cracking it open. When the rover's cameras focused on what the robot had tripped over, scientists spotted peculiar yellow crystals gleaming among the rock's newly exposed innards.
