In a first, NASA deploys climate change satellites to track polar heat loss

The satellites will measure the amount of heat that Earth emits into space from two of the planet’s coldest and most remote regions.The US space agency launched the satellites on May 25 using a Rocket Lab Electron rocket from Launch Complex 1 in Mahia, New Zealand.

Soon after the launch, ground controllers contacted the first PREFIRE CubeSat. According to NASA, the second CubeSat will be launched from Launch Complex 1 on an Electron rocket shortly. Following a 30-day checkout period to confirm normal operations, the mission is expected to continue for ten months.

“NASA’s PREFIRE will give us new measurements of the far-infrared wavelengths being emitted from Earth’s poles, which we can use to improve climate and weather models and help people around the world deal with the consequences of climate change,” said Tristan L’Ecuyer, PREFIRE’s principal investigator from the University of Wisconsin, Madison.
