Want to know what it’s like in outer space? Your best bet is under the sea. Life on a deep-space mission may be a lot like life in a deep-sea submersible, and the extreme environments found on the sea floor may give us clues as to where to look for life on other planets. In this episode, Emily, Matt, and Nick talk deep-sea diving, marine microbes, prog rock, and Emily’s favorite – ocean worlds. Guests include oceanographer and microbiologist Dr. Julie Huber of the Woods Hole Oceanographic Institution and NASA astronaut Randy Bresnik.
