Rocket Lab’s Electron rocket lifted off from Launch Complex 1 at Māhia, New Zealand at 3:15 p.m. NZST Wednesday, June 5 (11:15 p.m. EDT Tuesday, June 4), on the second of two launches of NASA’s PREFIRE (Polar Radiant Energy in the Far-InfraRed Experiment) mission. 

The PREFIRE mission will help close a gap in our understanding of how much of Earth’s heat is lost to space from the Arctic and Antarctica. Each PREFIRE satellite is equipped with an instrument called a thermal infrared spectrometer. The instrument contains specially shaped mirrors and detectors for splitting and measuring infrared light. 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. 

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. The agency’s Jet Propulsion Laboratory in Southern California manages the mission for NASA’s Science Mission Directorate and provided the instruments. Blue Canyon Technologies built 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. 

NASA’s Launch Services Program, based at agency’s Kennedy Space Center in Florida, selected Rocket Lab to provide the launch service as part of the agency’s VADR (Venture-class Acquisition of Dedicated and Rideshare) launch services contract. 

This concludes our coverage of the “PREFIRE and Ice” launch. The team is now working to establish communications with this PREFIRE CubeSat and will provide confirmation when signal is acquired.

Rocket Lab’s Electron Rocket ‘Go’ for Launch!

The mission team has called out “go for launch” for Rocket Lab’s PREFIRE and Ice launch, with the second of two launches of NASA’s PREFIRE mission now just minutes away! 

The CubeSat – about the size of a bread loaf – is set to launch aboard the company’s Electron rocket, from Launch Complex 1 at Māhia, New Zealand. 

The Electron is a vertically launched, two-stage rocket around 60 feet (18 meters) tall, with an exterior made of a carbon fiber composite, that can carry payloads weighing up to about 700 pounds (320 kilograms). Each Electron rocket uses nine Rutherford sea-level engines on its first stage, a single Rutherford vacuum engine on its second stage, and uses liquid oxygen and kerosene as propellants. The Rutherford engine is the world’s first 3D-printed, electric-pump-fed rocket engine. 

The kick stage is a third stage of the Electron rocket used to circularize and raise orbits to deploy payloads to unique and precise orbital destinations, powered by Rocket Lab’s Curie engine.

Members of today’s launch team are located within Rocket Lab’s private control facilities at Launch Complex 1 on the North Island of New Zealand. From the launch site it is possible to reach orbital inclinations from sun-synchronous through to 30 degrees, enabling versatility for missions to low Earth orbit. NASA’s Launch Services Program team and spacecraft customer team will be on console at Rocket Lab Headquarters in Long Beach, California. 

NASA’s Second PREFIRE Launch Coverage Now Underway

Live coverage of the second and final launch of NASA’s PREFIRE (Polar Radiant Energy in the Far-InfraRed Experiment) mission is underway. Rocket Lab is targeting Wednesday, June 5 at 3:15 p.m. NZST (11:15 p.m. EDT Tuesday, June 4) for launch of “PREFIRE and Ice,” which will send the agency’s CubeSat to low Earth orbit to measure the amount of heat Earth radiates into space from two of the coldest, most remote regions on the planet. 

Watch Rocket Lab’s launch broadcast on the company’s website. 

NASA’s Second PREFIRE Mission: Small Satellites, Big Science

NASA’s PREFIRE (Polar Radiant Energy in the Far-InfraRed Experiment) mission will fly a pair of shoebox-size cube satellites, or CubeSats, that will measure the amount of heat Earth radiates into space from two of the coldest, most remote regions on the planet – Earth’s polar regions. 

At the heart of the PREFIRE mission is Earth’s energy budget – the balance between incoming heat energy from the Sun and the outgoing heat given off by the planet. The difference between the two is what determines the planet’s temperature and climate. A lot of the heat radiated from the Arctic and Antarctica is emitted as far-infrared radiation, but there is currently no detailed measurement of this type of energy. 

The water vapor content of the atmosphere, along with the presence, structure, and composition of clouds, influences the amount of far-infrared radiation that escapes into space from Earth’s poles. Data collected from PREFIRE will give researchers information on where and when far-infrared energy radiates from the Arctic and Antarctic environments into space. 

The PREFIRE mission features miniaturized thermal infrared spectrometers on both CubeSat satellites. Once deployed, the CubeSats will settle into a polar orbit to measure far-infrared emissions and how they change throughout the day and over seasons. The observations will allow scientists to assess how changes in thermal infrared emissions at the top of Earth’s atmosphere are related to changes in cloud cover and surface conditions below, such as the amount of sea ice and meltwater on the surface of the ice. 

NASA’s PREFIRE mission will fill a gap in our understanding of how much of Earth’s heat is lost to space from the polar regions. By capturing measurements over the poles that can only be gathered from space, PREFIRE 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.

Launch Reset for NASA’s Second PREFIRE Climate Mission

The PREFIRE (Polar Radiant Energy in the Far-InfraRed Experiment) 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.

NASA and Rocket Lab now are targeting no earlier than 3 p.m. NZST, Wednesday, June 5, (11 p.m. EDT, Tuesday, June 4) for the launch of the second CubeSat for the agency’s PREFIRE (Polar Radiant Energy in the Far-InfraRed Experiment) mission. Rocket Lab waved off the June 1 launch attempt of “PREFIRE and Ice” due to out of range temperatures of the liquid oxygen propellant.

The PREFIRE mission consists of two shoebox-size cube satellites, or CubeSats, that will measure the amount of heat Earth radiates into space from two of the coldest, most remote regions on the planet. Data from the PREFIRE mission will help researchers better predict how Earth’s ice, seas, and weather will change in a warming world. 

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. Ground controllers established communications with the first CubeSat within hours of the launch.  

NASA and the University of Wisconsin-Madison jointly developed the PREFIRE mission. The agency’s Jet Propulsion Laboratory, 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.

NASA’s PREFIRE (Polar Radiant Energy in the Far-InfraRed Experiment) mission will fly a pair of CubeSat satellites to probe a little-studied portion of the radiant energy emitted by Earth’s polar regions for clues about Arctic warming, sea ice loss, and ice sheet melting.

The Arctic and Antarctica help regulate Earth’s overall temperature by radiating back into space much of the excess energy from the Sun that is absorbed at lower latitudes. Current satellite instruments do not detect all the wavelengths of this energy radiating from polar regions. These CubeSats will fill in the current data gap at far-infrared wavelengths, collecting information that will help scientists diagnose the impact of this outgoing radiation on Earth’s energy balance.

The PREFIRE mission features miniaturized thermal infrared spectrometers on two CubeSat satellites, which are each about the size of a loaf of bread. Once deployed, the CubeSats will settle into a polar orbit to measure far-infrared emissions and how they change throughout the day and over seasons. The observations will allow scientists to assess how changes in thermal infrared emissions at the top of Earth’s atmosphere are related to changes in cloud cover and surface conditions below, such as the amount of sea ice and meltwater on the surface of the ice.
