NASA's Curiosity Rover Spots Purple Rocks on Mars

Mars may appear red when viewed from Earth, but NASA's Curiosity rover has captured an up-close photo of the planet's mountainous landscape, with purple-colored rocks littered across the foreground. This remarkable new photo was captured near the base of Mars' Mount Sharp. The image's three frames were taken by Curiosity's Mast Camera (Mastcam)on Nov. 10.
