John Batchelor and I welcomed Dr. Michael Mumma to the show to discuss water and oceans throughout the solar system. We focused in on Mars oceans and where the water might have gone, plus we talked about sub-surface oceans on Enceladus, and oceans on Ganymede and Europa. We also talked about early in solar system history the trading ejecta with planets and other terrestrial bodies. I asked about similarities in solar system oceans to the oceans here on Earth, plus I asked if the oceans and bodies of water on these celestial bodies were similar in make-up to oceans on Earth. Our guest said there was no wind, waves, or tides but there was clear water movement. Also, the discovery of water and oceans was very puzzling in many locations. With the Dawn spacecraft now in orbit around Ceres, we also talked about water vapor and plumes on Ceres with more to come as Dawn gets closer and closer to the Ceres surface.
