PREFIRE CubeSat Image

This image shows one of two shoebox-size satellites that make up NASA's Polar Radiant Energy in the Far-InfraRed Experiment (PREFIRE) mission. PREFIRE will measure the amount of heat Earth emits into space from two of the coldest, most remote regions on the planet. Data from the cube satellites, or CubeSats, will improve computer models researchers use to predict how Earth's ice, seas, and weather will change in a warming world.
