The animation was created and produced by media art students from the Savannah College of Art in Design (SCAD) in Georgia, in collaboration with NASA’s Ice, Cloud and Land Elevation Satellite-2 (ICESat-2) mission. Their goal was to communicate the science and engineering of the mission, slated for launch in 2018. ICESat-2, managed by NASA Goddard in Greenbelt, Maryland, will measure the height of a changing Earth, one laser pulse at a time, 10,000 laser pulses a second. ICESat-2 will carry a photon-counting laser altimeter that will allow scientists to measure the elevation of ice sheets, glaciers, sea ice and more - all in unprecedented detail. The workings of this laser helped inspire students to create the character of Pho and plot his adventure. Our planet's frozen and icy areas, called the cryosphere, are a key focus of NASA's Earth science research. ICESat-2 will help scientists investigate why, and how much, our cryosphere is changing in a warming climate. The satellite will also measure heights across Earth's temperate and tropical regions, and take stock of the vegetation in forests worldwide.

Lagging behind the snow by a month or so, sea ice spreads across the Arctic Ocean and infiltrates the channels, islands and bays of Alaska and Canada. Snow and sea ice share this leading-and-lagging relationship because of the different rates at which the ground and oceans absorb and emit heat. Land temperatures drop more quickly, and extensive snow cover settles in by October. The ocean has a longer memory of temperature. Arctic waters retain enough heat in fall to keep ice from forming well after snow has accumulated on solid ground at the same latitude. Likewise, Arctic sea ice doesn't reach its annual maximum extent until late March, typically more than a month after the snow cover peak. In the visualization below, keep an eye on the massive Hudson Bay in northern central Canada: Snow encircles the frigid body of water before the first sea ice creeps into the bay.

Snow plays a key role in the Earth's energy balance, reflecting most of the sunlight that reaches its surface back to space, preventing warming of the ground beneath. Snow also absorbs energy from the atmosphere during spring melt, keeping temperatures moderate. Satellite measurements of snow extent began in the 1960s, and this lengthy record shows a 10 percent decline in annual snow cover since 1966, mainly due to earlier spring melting. Darker, snow-free ground absorbs more solar radiation and emits more warmth to the atmosphere. The snow cover loss is also a concern for those who depend on snowmelt for drinking water. Watch the visualizations below, based on data from NASA's MODIS instrument, to see the dramatic variation in a year of Earth's snow cover. In the Northern Hemisphere, the first flakes fall in mid-September over Siberia and Alaska. By the end of February, snow cover starts its retreat northward.

FROZEN features the global cryosphere, those places on Earth where the temperature doesn't generally rise above water's freezing point. As one of the most directly observable climate gauges, the changing cryosphere serves as a proxy for larger themes.But just as thrilling as this unusual—and unusually realistic—look at the planet's structure and behavior is the sheer fun and fascination of looking at a spherically shaped movie.
