NASA's Curiosity discovers purple rocks on Mars

NASA’s Mars Curiosity rover has captured an up—close image of the red planet’s mountainous landscape, with purple-coloured rocks littered across the foreground.
●    The image captured from the Mast Camera (Mastcam) on Curiosity Mars rover shows purple—hued rocks near the rover’s late—2016 location on lower Mount Sharp.
●    The scene’s middle distance includes higher layers that are future destinations for the mission.
●    Variations in colour of the rocks hint at the diversity of their composition on lower Mount Sharp, NASA said.
●    The purple tone of the foreground rocks has been seen in other rocks where Curiosity’s Chemical and Mineralogy (CheMin) instrument has detected hematite.
