NASA plans to launch the second CubeSat for its PREFIRE mission on June 1, utilizing advanced technology to study Earth’s polar heat emissions and contribute to climate research.
NASA and Rocket Lab are targeting Saturday, June 1, to launch the second CubeSat for the agency’s PREFIRE (Polar Radiant Energy in the Far-InfraRed Experiment) mission. The launch window opens at 3 p.m. NZST on Saturday, June 1 (11 p.m. EDT on Friday, May 31).
The first satellite successfully launched on 7:41 p.m. NZST May 25 (3:41 a.m. EDT) on an Electron rocket, called “Ready, Aim, PREFIRE,” from Launch Complex 1 in Māhia, New Zealand. Rocket Lab is now processing the second Electron rocket, called “PREFIRE and Ice,” for launch also from Launch Complex 1 in New Zealand.

These small PREFIRE satellites will fill a gap in our understanding of how much of Earth’s heat is lost to space from the polar regions. The mission will enable researchers to systematically study the planet’s heat emissions in the far-infrared – with 10 times finer wavelength resolution than any previous sensor, and provide clues about sea ice loss, ice sheet melting, and a warming Arctic.
NASA and the University of Wisconsin-Madison jointly developed the PREFIRE mission. The agency’s Jet Propulsion Laboratory (JPL), located in Southern California, manages the mission for NASA’s Science Mission Directorate and provided the spectrometers. Blue Canyon Technologies built the CubeSats, and the University of Wisconsin-Madison will process the collected data.
NASA’s Launch Services Program selected Rocket Lab to launch both spacecraft as part of the agency’s VADR (Venture-class Acquisition of Dedicated and Rideshare) contract. CubeSats like PREFIRE serve as an ideal platform for technical and architecture innovation, contributing to NASA’s science research and technology development.
