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.
Each of PREFIRE’s cube satellites, or CubeSats, will use a thermal infrared spectrometer to measure the heat, in the form of far-infrared energy, radiated into space by Earth’s surface and atmosphere. The CubeSats will gather data over the poles using sensors that are sensitive to 10 times more infrared wavelengths than any similar instrument. Information gathered by the mission will advance our understanding of when and where the poles shed heat into space, as well as why the Arctic has warmed more than 2½ times faster than the rest of the planet since the 1970s.
