Launch day is here for the first of two launches of NASA’s PREFIRE (Polar Radiant Energy in the Far-InfraRed Experiment) mission. Rocket Lab of Long Beach, California, is providing the launch service.

A small satellite – a CubeSat, about the size of a shoebox – waits on Rocket Lab’s Electron rocket for liftoff from Launch Complex-1 in Māhia, New Zealand. Launch is targeted for 7:28 p.m. NZST Saturday, May 25 (3:28 a.m. EDT). Back-up opportunities are available throughout May and into June should the launch date need to be updated for any reason.

The mission will send two CubeSats to asynchronous, near-polar orbits, and help to close a gap in our understanding of how much of Earth’s heat is lost to space 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.

The first CubeSat launch, which Rocket Lab named “Ready, Aim, PREFIRE,” will be followed by the second CubeSat launch, named “PREFIRE and Ice,” scheduled to lift off in the coming weeks from New Zealand on an Electron rocket.

NASA’s Launch Services Program selected Rocket Lab to launch the mission as part of the agency’s VADR (Venture-class Acquisition of Dedicated and Rideshare) contract. Missions launched through VADR help foster growth in the commercial launch market while lowering the cost of access to space for science and technology research.

Stormy Weather Delays First NASA PREFIRE Launch

NASA and Rocket Lab are now targeting no earlier than Saturday, May 25, for the launch of NASA’s PREFIRE (Polar Radiant Energy in the Far-InfraRed Experiment) mission from Launch Complex 1 in Mahia, New Zealand. The team is standing down while a severe weather system moves across the launch site over the coming days.

The mission will send two CubeSats, small research satellites, to asynchronous, near-polar orbits to study how much of Earth’s heat is lost to space from the Arctic and Antarctica. A second launch will be scheduled after the completion of the first CubeSat launch.

Launch Date Set for NASA’s PREFIRE Mission to Study Polar Energy Loss

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 are targeting no earlier than Wednesday, May 22, 2024, for the first of two launches of the agency’s PREFIRE (Polar Radiant Energy in the Far-InfraRed Experiment) mission to study heat loss to space in Earth’s polar regions. For the PREFIRE mission, two CubeSats will launch on two different flights aboard the company’s Electron rockets from Launch Complex 1 in Māhia, New Zealand. Each launch will carry one satellite.

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 ten times finer wavelength resolution than any previous sensor.

The Arctic and Antarctic help regulate Earth’s climate by radiating heat initially absorbed at the tropics back into space. But for regions like the Arctic, the spectrum of 60% of the energy escaping to space hasn’t been systematically measured. Filling in this picture is important for understanding which parts of the polar environment are responsible for heat loss and why the Arctic has warmed more than 2.5 times faster than the rest of the planet. In addition to helping us understand how the poles serve as Earth’s thermostat, PREFIRE observations of this heat exchange can improve our understanding of the mechanisms of polar ice loss and related questions of sea level rise and sea ice loss.

The instruments will fly on two identical CubeSats – one instrument per CubeSat – in asynchronous, near-polar orbits.

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.

The launch, which Rocket Lab named “Ready, Aim, PREFIRE,” will be followed by a second CubeSat mission launch several weeks later.. The second launch, which the company calls “PREFIRE and Ice,” will also lift off from New Zealand on an Electron rocket. 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.

Solar Sail CubeSat Has Deployed from Rocket

NASA’s Advanced Composite Solar Sail System is confirmed to have deployed from Rocket Lab’s Electron kick stage. The satellite has reached low Earth orbit to begin its mission to test next-generation technology that uses the power of sunlight as propulsion.

Next, the solar sail satellite will power up and attempt initial contact with the ground; a process that may occur overnight or in the next several days.

NASA Ames manages the Advanced Composite Solar Sail System project and designed and built the onboard camera diagnostic system. NASA Langley designed and built the deployable composite booms and solar sail system. NASA’s Small Spacecraft Technology (SST) program office based at NASA Ames and led by the agency’s Space Technology Mission Directorate (STMD), funds and manages the mission. NASA STMD’s Game Changing Development program developed the deployable composite boom technology. Rocket Lab USA, Inc of Long Beach, California is providing launch services. NanoAvionics is providing the spacecraft bus. 

NASA’s Solar Sail: We Have Liftoff!

NASA’s Advanced Composite Solar Sail System Mission is on its way! The spacecraft has lifted off from the launch pad aboard Rocket Lab’s Electron rocket.

The microwave oven-sized satellite is on its way to low Earth orbit to test its next-generation solar sail technology, using the power of sunlight as propulsion.

It’s Launch Day for NASA’s New Solar Sail Mission!

Welcome to launch day for NASA’s Advanced Composite Solar Sail Mission! This next-generation solar sail technology, which uses the pressure of sunlight for propulsion, waits for liftoff atop a Rocket Lab Electron rocket at the company’s Launch Complex 1 in Māhia, New Zealand. This launch will send the solar sail satellite to low Earth orbit, where it will test technologies designed to advance future space travel and expand our understanding of our Sun and solar system.  

A one-hour launch window opens at 6:00 p.m. EDT (10:00 a.m. Wednesday, April 24, in New Zealand). Rocket Lab is providing a live launch broadcast, available on the company’s website approximately 30 minutes before launch.

Today’s launch aims to deploy the spacecraft about 600 miles above Earth, which is more than twice the altitude of the International Space Station. Following an initial flight stage lasting about two months, the microwave-oven sized CubeSat will deploy its solar sail. The mission consists of a series of maneuvers to demonstrate orbit raising and lowering, using only the pressure of sunlight acting on the sail.

Seeking Signal Acquisition

The final two TROPICS CubeSats successfully deployed from a Rocket Lab Electron rocket after launch. The rocket named Coming To A Storm Near You lifted off at at 11:46 p.m. EDT Thursday, May 25, (3:46 p.m. NZST Friday, May 26th).

The team is now working to seek signal acquisition from this pair of TROPICS CubeSats. NASA will continue to assess data from periodic pass opportunities over ground stations located across the globe. It is not unexpected for CubeSats to take some time to establish communications. We will provide confirmation when signal is acquired.

While the launches are complete, the scientific work on orbit for the constellation is just beginning. So, continue to follow along for blog updates and stay connected with the mission on social media. This concludes our coverage of this launch.
