Mars has captivated the imaginations of humankind for centuries. The Perseverance rover will dig into the Red Planet’s past to find out if ancient life once existed on the Martian surface — but to fully understand what we want to learn, we have to look back at what we already know. In this episode, scientists Roger Wiens and Nina Lanza talk about some of the discoveries we’ve already made — and what the future could hold.
