In a literal plunge into the unknown, a two-man submersible is dropped into the cold waters of the Antarctic on a mission of discovery. The crew members’ aim? To go deeper under the waves near the South Pole than any other expedition in human history has done so previously. And what they discover down there is an incredible glimpse into a world that no one has ever set eyes on before.
This wasn’t a spur-of-the-moment plan, however. In fact, two years of careful research went into finding the perfect time and place to make the monumental dive. And there’s a very good reason for that. You see, we know more about other planets in our solar system than we do about the Earth’s ocean floor.
