The PREFIRE mission aims to collect data on the thermal emissions from the Arctic and Antarctica into space and their impact on global climate.
The first of two climate satellites, designed by NASA to study heat emissions from Earth’s poles, has successfully reached orbit. It was launched atop Rocket Lab’s Electron rocket from Māhia, New Zealand. The mission, known as PREFIRE (Polar Radiant Energy in the Far-InfraRed Experiment), involves two CubeSats that will measure the amount of heat Earth emits into space from these remote regions. The data gathered will enhance predictions regarding changes in Earth’s ice, seas, and weather patterns in a warming world.
NASA officials highlighted that PREFIRE will contribute crucial insights into Earth’s energy system, providing detailed information on how polar regions influence the planet's energy absorption and release. This knowledge is vital for predicting phenomena like sea ice loss, ice sheet melting, and sea level rise, which are critical for various sectors, including agriculture, fishing, and coastal communities.
Following successful communication establishment with the first CubeSat, the second is scheduled for launch shortly. After a 30-day validation phase, the mission is expected to operate for 10 months. Central to PREFIRE is Earth's energy budget, where the balance between incoming solar heat and outgoing planetary heat determines global temperature and climate. The mission will focus on measuring far-infrared radiation, a type of heat emitted predominantly from the Arctic and Antarctica, which remains poorly understood.
Equipped with thermal infrared spectrometers, the CubeSats will observe and measure these infrared wavelengths. The miniaturization of these instruments for CubeSat deployment required significant technological adaptation. Scientists hope that the data collected by PREFIRE will improve climate and weather models, aiding global efforts to understand and mitigate the impacts of climate change.
NASA's Launch Services Program, in collaboration with the University of Wisconsin-Madison, Blue Canyon Technologies, and Rocket Lab USA Inc., has facilitated the PREFIRE mission. NASA's Jet Propulsion Laboratory manages the mission, underscoring its significance within the agency's Science Mission Directorate.
