Carolyn Porco, the leader of the Imaging Experiment on NASA's Cassini mission, is here to answer your questions about exploring other planets, what we know about planetary rings, Saturn's moon Encleadus, and looking for life in our solar system.
Much of her research has focused on the how, why, and what of planetary rings, including an arc of rings around Neptune that she discovered. Currently, she's also focusing on Enceladus, Saturn's tiny moon with the big ocean — and a good candidate for being able to support life.
Besides leading the Cassini imaging experiment mission in its quest to get a closer look at Saturn, Porco has also worked as an imaging scientist on both Voyager's mission to the edges of our solar system and on the New Horizons trip to Pluto.
She'll be joining us from 11:00 a.m. - noon (Pacific time). So start asking her questions now about what we can see on Saturn, the inner workings of planetary rings, exploring other worlds, and just what's going on up on Enceladus.
