How close are we to discovering life on other planets? NASA’s Perseverance rover is due to land on Mars in 2021 to search for signs of ancient life and collect rock and soil samples for possible return to Earth. Jupiter’s moon Europa is home to a vast subsurface ocean—a body of water that could sustain primitive forms of life on this alien world nearly 600 million miles from our planet. Join planetary scientist and astrobiologist Kevin Peter Hand and NASA engineer Kobie Boykins for the latest intriguing updates on this vast frontier of exploration.
