This artist’s concept depicts one of two PREFIRE CubeSats in orbit around Earth. The NASA mission will measure the amount of far-infrared radiation the planet’s polar regions shed to space – information that’s key to understanding Earth’s energy balance.

The second CubeSat launch of the agency’s PREFIRE (Polar Radiant Energy in the Far-InfraRed Experiment) mission to study heat loss to space in Earth’s polar regions. The CubeSat will launch aboard Rocket Lab's Electron rocket from Launch Complex 1 in Māhia, New Zealand.
