Mars rover's selfie

NASA's Mars Curiosity rover took an out-of-this-world image on June 24 to mark a full Martian year, which is 687 days on Earth. It had a productive year, between collecting rock samples and discovering a former lakebed that NASA says had "essential elemental ingredients for life." But no word on how close it is to finding living organisms capable of taking selfies.
