Red Planet Selfies: Mars Rover Curiosity Poses on Mount Sharp (Photos)

NASA's Mars rover Curiosity has captured two more otherworldly selfies. The 1-ton robot's latest self-portraits were snapped May 11 in the foothills of the 3.4-mile-high (5.5 kilometers) Mount Sharp, at a site dubbed Okoruso. Curiosity had stopped there to drill into the mudstone bedrock and collect samples for analysis, NASA officials said.
