NASA's Goddard Space Flight Center in Greenbelt, Md., produced a film called "Frozen" for the "Science on a Sphere" projection system, a fully spherical video technology developed by the National Oceanic and Atmospheric Administration. "Frozen" probes all parts of Earth where water exists in solid form as snow or ice, known as the cryosphere. It then projects dramatic displays of satellite data of Earth, including changing Arctic sea ice and global snow cover, onto the sphere. [Source: NASA Earth Observatory]
