Don't miss this selfie from the red planet.

NASA's rover Curiosity has started drilling on Mars for the third time and did not miss the opportunity to take its Martian self-portrait.

The drill has begun at a geologically interesting location nicknamed 'The Kimberley'.

In this selfie, Curiosity appears to be leaning its 'head' -- a suite of instruments including the Chemcam and Mastcam cameras to the side - capturing the 5 km high Aeolis Mons ('Mount Sharp') on the horizon.
