How the Perseverance rover will look for extinct life on Mars

Big space news this week, as NASA landed the rover Perseverance on Mars. It was an incredible achievement to just get the rover on the planet, and now Perseverance has an important mission: to seek out signs of what used to be life. We had tons of questions about the mission and the technical achievement that was just landing on Mars, so we called a friend of the podcast to explain what happened and why it matters. Dr. Eric Jensen, Professor of Astronomy at Swarthmore College joins KYW Newsradio In Depth to talk about what exactly goes into building a robot and flying it to Mars, and what the team behind Perseverance hopes to find.
