NASA Partnerships Allow Artificial Intelligence to Predict Solar Events

NASA - Breaking News - Tue, 09/09/2025 - 11:43am

In the summer of 2024, people across North America were amazed when auroras lit up the night sky across their hometowns, but the same solar activity that makes auroras can cause disruptions to satellites that are essential to systems on Earth. The solution to predicting these solar events and warning satellite operators may come through artificial intelligence. 

The Frontier Development Lab of Mountain View, California, is an ongoing partnership between NASA and commercial AI firms to apply advanced machine learning to problems that matter to the agency and beyond. Since 2016, the Frontier Development Lab has applied AI on behalf of NASA in planetary defense, Heliophysics, Earth science, medicine, and lunar exploration.


Through a collaboration with a company called KX Systems, the Frontier Development Lab looked to use proven software in an innovative new way. The company’s flagship data analytics software, called kdb+, is typically used in the financial industry to keep track of rapid shifts in market trends, but the company was exploring how it could be used in space. 


Between 2017 and 2019, KX Systems participated in the Frontier Development Lab partnership through NASA’s Ames Research Center in Silicon Valley, California. Working with NASA scientists, KX applied the capabilities of kdb+ to searching for exoplanets and predicting space weather, areas which could be improved with AI models. One question the Frontier Development Lab worked to answer was whether kdb+ could forecast the kind of space weather that creates the auroras to predict when GPS satellites might experience signal interruption due to the Sun.


By importing several datasets monitoring the ionosphere, solar activity, and Earth’s magnetic field, then applying machine learning algorithms to them, the Frontier Development Lab researchers were able to predict disruptive events up to 24 hours in advance. 


While this was a scientific application of AI, KX Systems says some of this development work has made it back into its commercial offerings, as there are similarities between AI models developed to find patterns in satellite signal losses and ones that predict maintenance needs for industrial manufacturing equipment.


A division of FD Technologies plc., KX Systems is a technology company that offers database management and analytics software for customers that need to make decisions quickly. While KX started in 1993, its AI-driven business has grown considerably, and the company credits work done with NASA for accelerating some of its capabilities.


From protecting valuable satellites to keeping manufacturing lines moving at top performance, pairing NASA’s expertise with commercial ingenuity is a combination for success.

Ami Choi: Unraveling the Invisible Universe 

NASA - Breaking News - Tue, 09/09/2025 - 11:30am
Research Astrophysicist and Roman’s Deputy Wide Field Instrument Scientist – Goddard Space Flight Center

From a young age, Ami Choi — now a research astrophysicist at NASA — was drawn to the vast and mysterious. By the fifth grade, she had narrowed her sights to two career paths: marine biology or astrophysics. 

“I’ve always been interested in exploring big unknown realms, and things that aren’t quite tangible,” Choi said. That curiosity has served her all throughout her career.

In addition to conducting research, Ami Choi shares science with the public at various outreach events, including tours at NASA’s Goddard Space Flight Center in Greenbelt, Md. This photo captures one tour stop, outside the largest clean room at Goddard.Credit: NASA/Travis Wohlrab

As a student at University Laboratory High School in Urbana, Illinois, Choi gravitated toward astrophysics and was fascinated by things like black holes. She studied physics as an undergraduate at the University of Chicago, though she says math and physics didn’t necessarily come easily to her.

“I wasn’t very good at it initially, but I really liked the challenge so I stuck with it,” Choi said.

Early opportunities to do research played a pivotal role in guiding her career. As an undergraduate, Choi worked on everything from interacting galaxies to the stuff in between stars in our galaxy, called the interstellar medium. She learned how to code, interpret data, and do spectroscopy, which involves splitting light from cosmic objects into a rainbow of colors to learn about things like their composition.

After college, Choi read an article about physicist Janet Conrad’s neutrino work at Fermilab and was so inspired by Conrad’s enthusiasm and inclusivity that she cold-emailed her to see if there were any positions available in her group. 

On October 14, 2023, Ami took a break from a thermal vacuum shift to snap a selfie with a partial eclipse. She was visiting BAE, Inc. in Boulder, Co., where the primary instrument for NASA’s Nancy Grace Roman Space Telescope was undergoing testing. Credit: Courtesy of Ami Choi

“That one email led to a year at Fermilab working on neutrino physics,” Choi said.

She went on to earn a doctorate at the University of California, Davis, where she studied weak gravitational lensing — the subtle warping of light by gravity — and used it to explore dark matter, dark energy, and the large-scale structure of the universe.

Her postdoctoral work took Choi first to the University of Edinburgh in Scotland, where she contributed to the Kilo-Degree Survey, and later to The Ohio State University, where she became deeply involved in DES (the Dark Energy Survey) and helped lay the groundwork for the Nancy Grace Roman Space Telescope — NASA’s next flagship astrophysics mission. 

“One of my proudest moments came in 2021, when the DES released its third-year cosmology results,” Choi said. “It was a massive team effort conducted during a global pandemic, and I had helped lead as a co-convener of the weak lensing team.”

After a one-year stint at the California Institute of Technology in Pasadena, where Choi worked on SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer)—an observatory that’s surveying stars and galaxies—she became a research astrophysicist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. She also serves as the deputy Wide Field Instrument scientist for Roman. Choi operates at the intersection of engineering, calibration, and cosmology, helping translate ground-based testing into flight-ready components that will help Roman reveal large swaths of the universe in high resolution.

“I’m very excited for Roman’s commissioning phase — the first 90 days when the spacecraft will begin transmitting data from orbit,” Choi said.

She’s especially drawn to so-called systematics, which are effects that can alter the signals scientists are trying to measure. “People sometimes think of systematics as nuisances, but they’re often telling us something deeply interesting about either the physics of something like a detector or the universe itself,” Choi said. “There’s always something more going on under the surface.”

While she’s eager to learn more about things like dark energy, Choi is also looking forward to seeing all the other ways our understanding of the universe grows. “It’s more than just an end goal,” she said. “It’s about everything we learn along the way. Every challenge we overcome, every detail we uncover, is an important discovery too.”

For those who hope to follow a similar path, Choi encourages staying curious, being persistent, and taking opportunities to get involved in research. And don’t let the tricky subjects scare you away! “You don’t have to be perfect at math or physics right away,” she said. “What matters most is a deep curiosity and the tenacity to keep pushing through.”
