Twin NASA satellites launching May 22 are headed to ends of the Earth!
The PREFIRE mission will fill in critical missing data from Earth’s polar regions.


A new pair of shoebox-size climate satellites will soon be studying two of the most remote regions on Earth — the Arctic and Antarctic. Called the Polar Radiant Energy in the Far-InfraRed Experiment (PREFIRE), the mission’s twin satellites will measure the amount of heat the planet emits to space from these polar regions. This information is key to understanding how the planet’s incoming and outgoing heat influences Earth’s climate.

The mission’s cube satellites, or CubeSats, will both launch from Rocket Lab’s Launch Complex 1 in New Zealand. The first launch is planned for no earlier than May 22, 2024.

The planet’s poles help to regulate our climate by radiating a lot of the heat initially absorbed at the tropics back into space. Global temperatures are going up because of the increase in greenhouse gasses in the atmosphere – and the Arctic is warming more than 2.5 times faster than the rest of Earth. Data from NASA’s PREFIRE mission will target the critical polar regions to inform climate and ice models, improving scientists’ predictions of how the planet’s sea levels and weather are likely to change in a warming world.

PREFIRE was jointly developed by NASA and the University of Wisconsin-Madison and is managed by the agency’s Jet Propulsion Laboratory in Southern California.
