"NASA's Twin Spacecraft: Exploring Earth's Extremes"

NASA is launching two miniature CubeSats as part of the PREFIRE mission to study heat loss from Earth's polar regions, aiming to improve climate models and predictions. The satellites will carry thermal infrared spectrometers to measure far-infrared wavelengths of heat radiation, providing crucial data on climate variables such as atmospheric temperature, surface properties, water vapor, and clouds. The mission seeks to understand the impact of polar region changes on global weather patterns and sea level rise, ultimately enhancing our understanding of climate change.
