NASA Explorers is a new digital series that takes you inside the space agency and follows the pioneers, risk-takers and experts at the front line of exploration. Season 1, “Cryosphere,” joins NASA scientists on their journey to the frozen ends of the Earth as they study our rapidly changing world from satellites, planes and boots on the ground. The Cryosphere is a place we all depend on, but many of us will never go to. As temperatures rise, the frozen regions of Earth are changing rapidly. NASA scientists are locked in a race against time to understand our shifting climate and how it affects life on Earth.
