Witness a remarkable exchange between sailors racing against the forces of nature in the Southern Ocean and NASA astronauts on the largest modular space station in low Earth orbit. These two crews share a unique bond, experiencing life in extreme and hostile environments, limited living conditions, and both undertake scientific experiments for the health of the planet.
