What is the Mars Perseverance Rover Doing Now?

Briony Horgan, Associate Professor of Planetary Sciences at Purdue University, is working to determine whether we are alone in the Universe, or if life once existed on other planets such as Mars. She explains what the Perseverance Rover is doing on Mars, (like looking for ancient microbial life!), and talks about the samples and data that Perseverance is collecting. Briony also discusses a future NASA mission that will focus on returning samples to Earth (Mars Sample Return).
