Sarah Lewin, Associate Editor at, discusses the impact the Cassini spacecraft had on the exploration of Saturn, adding that "Cassini rewrote the textbook" on what scientists know about Saturn. She discusses NASA's plan to continue exploration of the planet thanks to the leads that Cassini sent, including the discovery of potential life on Saturn, noting some of the similar conditions the ringed planet has to Earth. We chat with Lewin a bit about NASA now turning its focus to Jupiter as well and the plan to dig deeper into exploration there.
