NASA Takes a Look Back at 2013
Mars
Mars is the centerpiece of NASA’s planetary exploration. The Curiosity rover continues to explore the planet, and in its first year already has accomplished its primary goal of determining that Mars could indeed have supported life in the past, possibly much later than originally thought. Curiosity’s Radiation Assessment Detector instrument is helping scientists assess round-trip radiation doses for a human mission to Mars.
