Briony Horgan, Professor of Planetary Science, joins us to discuss the Mars 2020 Perseverance Rover Mission. Perseverance follows Spirit and Opportunity, which were previous rovers searching for evidence of water on ancient Mars. Curiosity found evidence of a long-lived, habitable lake environment at Gale crater. Now that we know Mars had a habitable body of water, the Perseverance Rover Mission will be searching for signs of ancient microbial life on Mars. https://mars.nasa.gov/mars2020/
