Last year, NASA's Curiosity Rover  showed that Earth is not the only planet where one finds narcissistic, selfie obsessed beings. They exist on Mars as well. 

The car-sized robotic Rover has clicked a selfie again and shared it on social media. 

However, this time a Hrag Farra, a Facebook user asked on the page of NASA's Curiosity Mars Rover, that how does the machine manage to click selfies. Just as she was about to Google it, Rover replied to her comment.

So that's how it's done.
