While the Mars rovers Curiosity and Opportunity continue to set new records, NASA is looking at its next mission to the surface of the Red Planet. On Tuesday, the space agency released a 154-page report by the Mars 2020 Science Definition Team, which sets out the objectives and preliminary design of the probe scheduled to be sent to Mars in 2020. It's main task will be to seek out areas where life might exist and return samples to Earth.
