6 Min Read NASA’s PUNCH Mission to Revolutionize Our View of Solar Wind
Earth is immersed in material streaming from the Sun. This stream, called the solar wind, is washing over our planet, causing breathtaking auroras, impacting satellites and astronauts in space, and even affecting ground-based infrastructure.
NASA’s PUNCH (Polarimeter to Unify the Corona and Heliosphere) mission will be the first to image the Sun’s corona, or outer atmosphere, and solar wind together to better understand the Sun, solar wind, and Earth as a single connected system.
Launching no earlier than Feb. 28, 2025, aboard a SpaceX Falcon 9 rocket from Vandenberg Space Force Base in California, PUNCH will provide scientists with new information about how potentially disruptive solar events form and evolve. This could lead to more accurate predictions about the arrival of space weather events at Earth and impact on humanity’s robotic explorers in space.
“What we hope PUNCH will bring to humanity is the ability to really see, for the first time, where we live inside the solar wind itself,” said Craig DeForest, principal investigator for PUNCH at Southwest Research Institute’s Solar System Science and Exploration Division in Boulder, Colorado.

The PUNCH mission’s four suitcase-sized satellites have overlapping fields of view that combine to cover a larger swath of sky than any previous mission focused on the corona and solar wind. The satellites will spread out in low Earth orbit to construct a global view of the solar corona and its transition to the solar wind. They will also track solar storms like coronal mass ejections (CMEs). Their Sun-synchronous orbit will enable them to see the Sun 24/7, with their view only occasionally blocked by Earth.
Typical camera images are two dimensional, compressing the 3D subject into a flat plane and losing information. But PUNCH takes advantage of a property of light called polarization to reconstruct its images in 3D. As the Sun’s light bounces off material in the corona and solar wind, it becomes polarized — meaning the light waves oscillate in a particular way that can be filtered, much like how polarized sunglasses filter out glare off of water or metal. Each PUNCH spacecraft is equipped with a polarimeter that uses three distinct polarizing filters to capture information about the direction that material is moving that would be lost in typical images.
“This new perspective will allow scientists to discern the exact trajectory and speed of coronal mass ejections as they move through the inner solar system,” said DeForest. “This improves on current instruments in two ways: with three-dimensional imaging that lets us locate and track CMEs which are coming directly toward us; and with a broad field of view, which lets us track those CMEs all the way from the Sun to Earth.”
All four spacecraft are synchronized to serve as a single “virtual instrument” that spans the whole PUNCH constellation.
Crews conduct additional solar array deployment testing for NASA’s PUNCH (Polarimeter to Unify the Corona and Heliosphere) satellites at Astrotech Space Operations located on Vandenberg Space Force Base in California on Wednesday, Jan. 22, 2025. USSF 30th Space Wing/Alex Valdez The PUNCH satellites include one Narrow Field Imager and three Wide Field Imagers. The Narrow Field Imager (NFI) is a coronagraph, which blocks out the bright light from the Sun to better see details in the Sun’s corona, recreating what viewers on Earth see during a total solar eclipse when the Moon blocks the face of the Sun — a narrower view that sees the solar wind closer to the Sun. The Wide Field Imagers (WFI) are heliospheric imagers that view the very faint, outermost portion of the solar corona and the solar wind itself — giving a wide view of the solar wind as it spreads out into the solar system.
“I’m most excited to see the ‘inbetweeny’ activity in the solar wind,” said Nicholeen Viall, PUNCH mission scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “This means not just the biggest structures, like CMEs, or the smallest interactions, but all the different types of solar wind structures that fill that in between area.”
When these solar wind structures from the Sun reach Earth’s magnetic field, they can drive dynamics that affect Earth’s radiation belts. To launch spacecraft through these belts, including ones that will carry astronauts to the Moon and beyond, scientists need to understand the solar wind structure and changes in this region.
Building Off Other Missions
“The PUNCH mission is built on the shoulders of giants,” said Madhulika Guhathakurta, PUNCH program scientist at NASA Headquarters in Washington. “For decades, heliophysics missions have provided us with glimpses of the Sun’s corona and the solar wind, each offering critical yet partial views of our dynamic star’s influence on the solar system.”
When scientists combine data from PUNCH and NASA’s Parker Solar Probe, which flies through the Sun’s corona, they will see both the big picture and the up-close details. Working together, Parker Solar Probe and PUNCH span a field of view from a little more than half a mile (1 kilometer) to over 160 million miles (about 260 million kilometers).
Additionally, the PUNCH team will combine their data with diverse observations from other missions, like NASA’s CODEX (Coronal Diagnostic Experiment) technology demonstration, which views the corona even closer to the surface of the Sun from its vantage point on the International Space Station. PUNCH’s data also complements observations from NASA’s EZIE (Electrojet Zeeman Imaging Explorer) — targeted for launch in March 2025 — which investigates the magnetic field perturbations associated with Earth’s high-altitude auroras that PUNCH will also spot in its wide-field view.

NASA’s Goddard Space Flight Center Conceptual Image Lab As the solar wind that PUNCH will observe travels away from the Sun and Earth, it will then be studied by the IMAP (Interstellar Mapping and Acceleration Probe) mission, which is targeting a launch in 2025.
“The PUNCH mission will bridge these perspectives, providing an unprecedented continuous view that connects the birthplace of the solar wind in the corona to its evolution across interplanetary space,” said Guhathakurta.
The PUNCH mission is scheduled to conduct science for at least two years, following a 90-day commissioning period after launch. The mission is launching as a rideshare with the agency’s next astrophysics observatory, SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer).
“PUNCH is the latest heliophysics addition to the NASA fleet that delivers groundbreaking science every second of every day,” said Joe Westlake, heliophysics division director at NASA Headquarters in Washington. “Launching this mission as a rideshare bolsters its value to the nation by optimizing every pound of launch capacity to maximize the scientific return for the cost of a single launch.”
The PUNCH mission is led by Southwest Research Institute’s offices in San Antonio, Texas, and Boulder, Colorado. The mission is managed by the Explorers Program Office at NASA Goddard for NASA’s Science Mission Directorate in Washington.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
NASA marked a key milestone Feb. 18 with installation of RS-25 engine No. E20001, the first new production engine to help power the SLS (Space Launch System) rocket on future Artemis missions to the Moon.
The engine, built by lead SLS engines contractor L3Harris (formerly Aerojet Rocketdyne), was installed on the Fred Haise Test Stand in preparation for acceptance testing next month. It represents the first of 24 new flight engines being built for missions, beginning with Artemis V.

During missions to the Moon, RS-25 engines fire for about 500 seconds and up to the 111% power level to help launch SLS, with the Orion spacecraft, into orbit.
The engine arrived at the test stand from the L3Harris Engine Assembly Facility on the engine transport trailer before being lifted onto the vertical engine installer (VEI) on the west side deck. After rolling the engine into the stand, the team used the VEI to raise and secure it in place.
The upcoming acceptance test follows two certification test series that helped verify the new engine production process and components meet all performance requirements. Four RS-25 engines help launch SLS, producing up to 2 million pounds of combined thrust.
All RS-25 engines for Artemis missions are tested and proven flightworthy at NASA Stennis prior to use. RS-25 tests are conducted by a team of operators from NASA, L3Harris, and Syncom Space Services, prime contractor for site facilities and operations.

Title: Director of the Solar System Exploration Division, Sciences and Exploration Directorate and Deputy Principal Investigator of the DAVINCI Mission
Formal Job Classification: Planetary scientist
Organization: Solar System Exploration Division, Sciences and Exploration Directorate (Code 690)
Dr. Stephanie Getty, director of NASA Goddard’s Solar System Exploration Division, poses with a full-scale engineering unit of NASA’s DAVINCI (Deep Atmosphere Venus Investigation of Noble gases, Chemistry, and Imaging) descent sphere.Credits: Courtesy of Stephanie Getty What do you do and what is most interesting about your role here at Goddard? How do you help support Goddard’s mission?
As the Director of the Solar System Exploration Division, I work from a place of management to support our division’s scientists. As the deputy principal investigator of the DAVINCI (Deep Atmosphere Venus Investigation of Noble gases, Chemistry, and Imaging) mission, I work with the principal investigator to lead the team in implementing this mission to study the atmosphere of Venus.
I love that I get to work from a place of advocacy in support of my truly excellent, talented colleagues. I get to think strategically to make the most of opportunities and do my best to overcome difficulties for the best possible future for our teams. It’s also a fun challenge that no two days are ever the same!
Why did you become a planetary scientist?
In school, I had a lot of interests and space was always one of them. I also loved reading, writing, math, biology, and chemistry. Being a planetary scientist touches on all of these.
My dad inspired me become a scientist because he loved his telescope and photography including of celestial bodies. We watched Carl Sagan’s “Cosmos” often.
I grew up in southeastern Florida, near Fort Lauderdale. I have a B.S. and Ph.D. in physics from the University of Florida.
How did you come to Goddard?
“My goal is to provide a supportive environment for our incredibly talented science community in the Division to thrive, to push discovery forward and improve the understanding of our solar system,” said Dr. Stephanie Getty, director of NASA Goddard’s Solar System Exploration Division. “It’s a priority to encourage effective and open communication.”Credits: Courtesy of Stephanie Getty I had a post-doctoral fellowship in the physics department at the University of Maryland, and a local connection and a suggestion from my advisor led me to Goddard in 2004.
What is most important to you as director of the Solar System Exploration Division, Sciences and Exploration Directorate?
My goal is to provide a supportive environment for our incredibly talented science community in the Division to thrive, to push discovery forward and improve the understanding of our solar system. It’s a priority to encourage effective and open communication. I really try to value the whole person, recognizing that each of us is three-dimensional, with full personal lives. The people create the culture that allows our scientists to thrive and explore.
What are your goals as deputy principal investigator of the DAVINCI mission?
DAVINCI’s goal is to fill long-standing gaps about Venus, including whether it looked more like Earth in the past. Our energetic team brings together science, engineering, technology, project management, and business acumen to build a multi-element spacecraft that will explore Venus above the clouds, and during an hour-long descent through the atmosphere into the searingly hot and high pressure deep layers of the atmosphere near the surface. We hope to launch in June 2029.
What is your proudest accomplishment at Goddard?
I am pleased and proud to be deputy principal investigator on a major mission proposal that now gets to fly. It is an enormous privilege to be entrusted as part of the leadership team to bring the first probe mission back to Venus in over four decades.
What makes Goddard’s culture effective?
Goddard’s culture is at its best when we collectively appreciate how each member of the organization works towards solving our problems. The scientists appreciate the hard, detailed work that the engineers do to make designs. The engineers and project managers are energized by the fundamental science questions that underlie everything we do. And we have brilliant support staff that keeps our team organized and focused.
“Curiosity is a defining characteristic of a good scientist, never losing a sense of wonder,” says Dr. Stephanie Getty, director of NASA Goddard’s Solar System Exploration Division. “When I can, I try to make time to pause to reflect on how beautiful and special our own planet is.”Credits: Courtesy of Stephanie Getty What goes through your mind when you think about which fundamental science question to address and how?
A lot of the research I have done, including my mission work, has been inspired by the question of how life originates, how life originated on Earth, and whether there are or have been other environments in the solar system that could have ever supported life. These questions are profound to any human being. My job allows me to work with incredibly talented teams to make scientific progress on these questions.
It is really humbling.
Who inspired you?
My 10th grade English teacher encouraged us to connect with the natural world and to write down our experiences. Exploring the manifestations of nature connects with the way I approach my small piece of exploring the solar system. I really love the writing parts of my job, crafting the narrative around the science we do and why it is important.
As a mentor, what is the most important lesson you give?
A successful career should reflect both your passion and natural abilities. Know yourself. What feels rewarding to you is important. Learn how to be honest with yourself and let yourself be driven by curiosity.
Our modern lives can be very noisy at work and at home. It can be hard to filter through what is and is not important. Leaving space to connect with the things that satisfy your curiosity can be one way to make the most of the interconnectivity and complexity of life.
Curiosity not only connects us to the natural world, but also to each other. Curiosity is a defining characteristic of a good scientist, never losing a sense of wonder.
I’m looking out my window as we talk. When I can, I try to make time to pause to reflect on how beautiful and special our own planet is.
What are your hobbies?
I love hiking with my kids. Walking through the woods puts me in the moment and clears my mind better than anything else. It gives my brain a chance to relax. Nature gives perspective, it reminds me that I am part of something bigger. Walking in the woods gives me a chance to pause, for example, to notice an interesting rock formation, or watch a spider spinning an impressive web, or spot a frog trying to camouflage itself in a pond, and doing this with my children is my favorite pastime.
Where is your favorite place in the world?
Any campsite at dusk with a fire going and eating s’mores with my family.
Conversations With Goddard is a collection of Q&A profiles highlighting the breadth and depth of NASA’s Goddard Space Flight Center’s talented and diverse workforce. The Conversations have been published twice a month on average since May 2011. Read past editions on Goddard’s “Our People” webpage.
