In the first episode on our Earth and Space Series, we heard a little bit about how research on Earth’s oceans has had major implications for the search for life in the cosmos. Here, we’ve published an extended interview with a pioneer in this area of exploration: Dr. Christopher German. Dr. German is a Senior Scientist who focuses on geochemistry at the Woods Hole Oceanographic Institution. In this extended interview, you can hear more about Ocean Worlds, the search for life in our solar system, the technology that makes this possible, and how Dr. German was able to bring together the fields of oceanography and astrobiology. You can learn more about Dr. German and his work at https://www.whoi.edu/profile/cgerman/ and NASA’s Ocean Worlds project at https://oceanworlds.whoi.edu/ This interview was recorded on April 14, 2021.
