A New Era in Climate Science Begins
Rocket Lab’s Electron rocket lifted off from Launch Complex 1 at 7:41 p.m. NZST (3:41 a.m. EDT), carrying the shoebox-sized satellite into orbit. The launch represents the first of two PREFIRE CubeSats, with the second satellite scheduled to follow shortly. The successful deployment was confirmed at 8:35 p.m. NZST (4:35 a.m. EDT), initiating a 30-day checkout period for the spacecraft.
PREFIRE’s primary goal is to measure the far-infrared heat emissions from Earth’s poles. Until now, such measurements have been largely theoretical, lacking direct observational data. Karen St. Germain, NASA’s Earth Science Division Director, emphasized the mission’s importance, stating, “This new information—and we’ve never had it before—will improve our ability to model what’s happening in the poles, what’s happening in climate.”

The data collected by PREFIRE will help scientists understand how various atmospheric elements, such as water vapor and clouds, affect the heat balance at the poles. This knowledge is crucial for predicting future climate scenarios, including sea level rise and changing weather patterns.
The Role of CubeSats
CubeSats are small, cost-effective satellites designed for specific scientific missions. St. Germain highlighted their strategic value, noting, “Larger satellites can be thought of as ‘generalists’ and the small ones as ‘specialists.’ NASA needs both.” PREFIRE’s CubeSats are equipped with thermal infrared spectrometers that will provide unprecedented measurements of far-infrared radiation from the poles.

Tristan L’Ecuyer, PREFIRE’s principal investigator from the University of Wisconsin-Madison, explained the broader significance of the mission. “The process of getting the heat from the tropical regions to the polar regions is what drives all of our weather around the planet,” he said. By understanding this heat transfer, scientists can improve climate and weather models, ultimately aiding in global climate adaptation efforts.
The mission’s data will be invaluable for diverse sectors, from farming and fishing to coastal community planning. As Laurie Leshin, Director of NASA’s Jet Propulsion Laboratory, pointed out, “Their observations will help us understand the fundamentals of Earth’s heat balance, allowing us to better predict how our ice, seas, and weather will change in the face of global warming.”
Future Collaboration and Prospects
PREFIRE is a collaborative effort between NASA and the University of Wisconsin-Madison, with NASA’s Jet Propulsion Laboratory managing the mission. The CubeSats were built by Blue Canyon Technologies, and the launch services were provided by Rocket Lab USA Inc. This mission is part of NASA’s Earth Venture line, which focuses on cost-effective, innovative Earth science missions.
Rocket Lab CEO Peter Beck expressed enthusiasm for the mission, stating, “Missions like PREFIRE demonstrate the unique benefit of Electron: dedicated launch for small satellites to precise orbits on precise schedules.”
The PREFIRE mission marks a significant advancement in climate science, providing essential data on polar heat emissions that will enhance our understanding of climate dynamics. As the PREFIRE CubeSats begin their observations, the scientific community anticipates groundbreaking insights that will inform future climate models and help address the pressing challenges of global warming. NASA’s commitment to innovative and cost-effective missions like PREFIRE underscores its dedication to advancing Earth science and supporting global climate resilience.
