NASA’s Mars Curiosity Rover Celebrates a Martian Year

What better way to mark 687 days on Mars than with a selfie photograph? NASA released a photo this week marking the accomplishments of the Curiosity Mars rover since it landed on the Red Planet in August 2012. The rover used the camera at the end of its arm to take dozens of action shots that were combined and released to the public. During the Martian year, which is 687 days, the rover completed its primary mission by proving that “Mars once offered environmental conditions favorable for microbial life.”
