The PREFIRE Mission

Heat emissions from Earth’s polar regions are a critical component of our planet’s climate system. However, we know surprisingly little about how this heat is lost to space. NASA’s Polar Radiant Energy in the Far-Infrared Experiment (PREFIRE) aims to change that. This mission, involving two small cubesats, will provide unprecedented data on the far-infrared radiation emitted from the Arctic and Antarctic, offering new insights into the polar climate and its broader impacts on global weather systems.

Mission Overview

The Satellites

PREFIRE consists of two cubesats, rightly named “Ready, Aim, PREFIRE” and “PREFIRE and ICE.” These compact satellites, each about the size of a loaf of bread, will launch separately into near-polar orbits. The first cubesat is scheduled to launch on May 22, 2024, aboard a Rocket Lab Electron rocket from Māhia, New Zealand. The second will follow a few days later.

Scientific Goals

The primary goal of PREFIRE is to measure far-infrared radiation, specifically wavelengths longer than 15 microns. This spectrum accounts for approximately 60% of the total heat lost at the poles. “We’ve never measured that before,” said Tristan L’Ecuyer, PREFIRE’s Principal Investigator at the University of Wisconsin-Madison, emphasizing the mission’s groundbreaking nature.

The Importance of Polar Heat Emissions

Rapid Arctic Warming

The Arctic is experiencing warming at a rate faster than any other region on Earth, leading to significant changes in local ecosystems and global weather patterns. Understanding how heat is emitted from this region is crucial for predicting future climate changes. “Ultimately, [PREFIRE] information is going to be combined with our climate models,” L’Ecuyer explained, “and hopefully we’ll be able to improve our ability to simulate what sea level rise might look like in the future.”

Global Climate Impacts

The data collected by PREFIRE will be invaluable in refining our climate models, particularly in understanding how polar changes affect weather systems worldwide. This includes better predictions of phenomena such as sea level rise and extreme weather events.

Technical Specifications

Instruments and Design

Each PREFIRE cubesat is equipped with a single thermal infrared spectrometer. These instruments are scaled-down versions of technology used in previous NASA missions, such as the Moon Mineralogy Mapper (M3) and the Mars Climate Sounder (MCS). Mary White, PREFIRE Project Manager at NASA’s Jet Propulsion Laboratory, noted, “We’ve adapted proven technology for a cost-effective, focused mission.”

Dual-Satellite Approach

Having two satellites provides a unique advantage. “Having one cubesat would be able to sort of map out what the emission looks like in the polar regions,” said L’Ecuyer. “We’ll be using the two cubesats to make measurements over the course of several hours, taking the difference between those measurements and trying to understand how the processes that are occurring in the Arctic are actually affecting the emission from the Arctic.”

Broader Context and Collaboration

Part of a Larger Effort

PREFIRE fits into NASA’s broader strategy of combining large-scale missions with smaller, specialized ones to create a comprehensive understanding of Earth’s climate system. Karen St. Germain, NASA’s Earth Science Division director, explained, “NASA needs both our large missions and these smaller missions… to answer this full range of questions we have about understanding the Earth as a system.”

Data Accessibility

In line with NASA’s commitment to open science, all data collected by PREFIRE will be freely available to the public. This ensures that researchers worldwide can access and utilize this valuable information to further our collective understanding of climate dynamics. “All NASA data are open and freely available to all scientists or all people who are interested around the world,” White confirmed.

Expected Outcomes

Enhanced Climate Models

The insights gained from PREFIRE will significantly enhance our climate models. By providing detailed measurements of far-infrared radiation, scientists can better understand the heat exchange processes at the poles and their influence on global climate systems. This will improve predictions of future climate scenarios, including the rate and impact of sea level rise.

Informed Policy Decisions

The data from PREFIRE will not only advance scientific knowledge but also inform policy decisions related to climate change mitigation and adaptation. Accurate climate models are essential for developing effective strategies to address the ongoing and future impacts of global warming.
