The PREFIRE mission will send two CubeSats – shown as an artist’s concept against an image of Earth from orbit – into space to study how much heat the planet absorbs and emits from its polar regions, including the Arctic and Antarctica. Credit: NASA/JPL-Caltech
Data from the PREFIRE mission will inform climate and ice models, providing better projections of how a warming world will affect sea ice loss, ice sheet melt, and sea level rise.
NASA has selected Rocket Lab USA Inc. of Long Beach, California, to provide the launch service for the agency’s PREFIRE (Polar Radiant Energy in the Far-InfraRed Experiment) mission, which aims to give researchers a more accurate picture of the energy entering and leaving Earth.
Both PREFIRE CubeSats will launch during the spring of 2024. PREFIRE Satellite 1 is nominally scheduled to launch on May 1, 2024, while PREFIRE Satellite 2 is scheduled for May 15, 2024.
Aims and Impact of PREFIRE
The PREFIRE mission will help close a gap in our understanding of how much of Earth’s heat is lost to space, especially from the Arctic and Antarctica. Analysis of PREFIRE measurements will inform climate and ice models, providing better projections of how a warming world will affect sea ice loss, ice sheet melt, and sea level rise. Improving climate models can ultimately help to provide more accurate projections on the impacts of storm severity and frequency, as well as coastal erosion and flooding.
Mission Components and Partnerships
The mission consists of two 6U CubeSats with a baseline mission length of 10 months and is jointly developed by NASA and the University of Wisconsin-Madison. NASA’s Jet Propulsion Laboratory in Southern California manages the mission for the agency’s Science Mission Directorate and is providing the instruments. Blue Canyon Technologies is building the CubeSats, and the University of Wisconsin-Madison will process the data collected by the instruments. The science team includes members from JPL and the Universities of Wisconsin, Michigan, and Colorado.
Announcement and Contract Details
NASA’s Launch Services Program, based out of the agency’s Kennedy Space Center in Florida, in partnership with NASA’s Earth System Science Pathfinder office, announced the launch service as part of the agency’s VADR (Venture-class Acquisition of Dedicated and Rideshare) launch services contract.
