NASA’s observational rover ‘Curiosity’ celebrates its first Martian anniversary today. Some of Curiosity’s first year highlights include the transmission of a Will-I-Am song from the red planet and the discovery of ‘Yellowknife Bay’, an area that was habitable billions of years ago. A full Martian year, in case you were wondering, lasts 687 days because Mars is further away from the Sun than the Earth. Dr. Mark Hammergren, an astronomer at the Adler Planetarium, joins us to talk about the Curiosity’s first 687 days on Mars and what lies ahead for the Martian rover.
