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. Earth absorbs a lot of the Sun's energy at the tropics, and weather and ocean currents transport that heat to the poles. Ice, snow, clouds, and other parts of the polar environment emit the heat into space, much of it in the form of far-infrared radiation. The difference between this incoming and outgoing heat helps to determines the planet's temperature and drives a dynamic system of climate and weather. But far-infrared emissions at the poles have never been systematically measured. This is where PREFIRE comes in. The crucial instrument on each spacecraft is a thermal infrared spectrometer, which will measure wavelengths of light in the far-infrared range. The mission will help researchers gain a clearer understanding of when and where Earth's poles emit far-infrared radiation, as well as how atmospheric water vapor and clouds influence the amount that escapes to space. https://photojournal.jpl.nasa.gov/catalog/PIA26186

NASA's Polar Radiant Energy in the Far-InfraRed Experiment (PREFIRE) mission will measure the amount of heat Earth emits into space from two of the coldest, most remote regions on the planet. Data from the mission will improve computer models researchers use to predict how Earth's ice, seas, and weather will change in a warming world. This artist's concept depicts one of two PREFIRE CubeSats in orbit around Earth. Earth absorbs a lot of the Sun's energy at the tropics, and weather and ocean currents transport that heat to the poles. Ice, snow, clouds, and other parts of the polar environment emit the heat into space, much of it in the form of far-infrared radiation. The difference between how much heat Earth absorbs at the tropics and then radiates out to space from the Arctic and Antarctic determines the planet's temperature and drives a dynamic system of climate and weather. But far-infrared emissions at the poles have never been systematically measured. This is where PREFIRE comes in. The mission will help researchers gain a clearer understanding of when and where Earth's poles emit far-infrared radiation, as well as how atmospheric water vapor and clouds influence the amount that escapes to space. PREFIRE is composed of two roughly shoebox-size CubeSats outfitted with specialized miniature heat sensors that will give researchers a more accurate picture of how much heat Earth emits into space. https://photojournal.jpl.nasa.gov/catalog/PIA26185

The PREFIRE (Polar Radiant Energy in the Far-InfraRed Experiment) mission will send two CubeSats – shown as an artist's concept against an image of Earth from orbit – into space to study how much heat the planet absorbs and emits from its polar regions, including the Arctic and Antarctica. Analysis of PREFIRE measurements will inform climate and ice models, providing better projections of how a warming world will affect sea ice loss, ice sheet melt, and sea level rise. Improving climate models can ultimately help to provide more accurate projections on the impacts of storm severity and frequency, as well as coastal erosion and flooding. The mission consists of two 6U CubeSats with a baseline mission length of 10 months and is jointly developed by NASA and the University of Wisconsin-Madison. NASA's Jet Propulsion Laboratory in Southern California manages the mission for the agency's Science Mission Directorate and is providing the instruments. Blue Canyon Technologies is building the CubeSats, and the University of Wisconsin-Madison will process the data collected by the instruments. The science team includes members from JPL and the Universities of Wisconsin, Michigan, and Colorado. https://photojournal.jpl.nasa.gov/catalog/PIA25778
