A New Study on Coronal Holes Improves Space Weather Forecasting
New Mexico State University (NMSU) astronomy graduate student Khagendra Katuwal studied 70 coronal holes on the sun to better understand the connection between solar activity and space weather. His paper was recently published in The Astrophysical Journal.
It Looks Like Europa Doesn't Have Plumes of Water Vapour After All
In 2014, researchers presented the discovery of water vapour plumes being emitted from Jupiter's moon Europa. This caused quite a stir; it meant that the moon's buried ocean was accessible without contending with the thick ice shell that concealed it. But new research by the same researchers questions those detections.

Psyche Spacecraft Completes Mars Flyby
NASA’s Psyche spacecraft completed its close approach of Mars on May 15, coming within 2,864 miles (4,609 kilometers) of the planet’s surface. During the flyby, it took this image and others. This representative color image, captured by Psyche’s multispectral imager instrument, features the double-ring crater Huygens and the surrounding heavily cratered southern highlands.
This flyby used a gravity assist from Mars to provide a critical boost in speed and to adjust the spacecraft’s orbital plane without using any onboard propellant, sending it on its way toward the metal-rich asteroid Psyche. When it arrives in August 2029, it will insert itself into orbit, then map the asteroid and gather science data. If the asteroid proves to be the metallic core of an ancient planetesimal, it could offer a one-of-a-kind window into the interior of rocky planets like Earth.
Learn more about the flyby and see more photos from the event.

NASA-developed AI Could Help Track Harmful Algae
NASA scientists have developed an artificial intelligence tool to take on a longstanding challenge in ocean waters. In a study recently published in AGU Earth and Space Science, researchers reported the tool was able to fuse data from multiple satellites and detect harmful algal blooms that occurred in western Florida and Southern California.
Severe blooms can pose health risks and cost coastal economies in the United States tens of millions of dollars every year. Areas in Florida such as Tampa Bay and Sarasota have wrestled with the problem for decades. A species called Karenia brevis can thrive in Gulf of America waters, spawning harmful algal blooms that kill wildlife, foul beaches, and sicken swimmers. On the West Coast, blooms of Pseudo-nitzschia have poisoned hundreds of dolphins, California sea lions, and other marine animals in recent years. Toxins from algaecan even enter the air and cause respiratory illness in humans.
To manage the risk, health agencies regularly test waters and issue warnings or beach closures when necessary. The National Oceanic and Atmospheric Administration (NOAA) works with states and other local partners to issue harmful algal bloom forecasts, like weather forecasts, during bloom seasons.
On-site testing requires hours in a boat to manually collect water samples that must be sent to a lab for analysis, taking a day or more and requiring multiple tests. It’s even more challenging to know where to test before a bloom starts spreading.
NASA’s Earth-orbiting satellites already track harmful algal blooms with their unique global view. By bringing together diverse datasets, the new AI tool could serve as a force multiplier to help communities determine where to focus their efforts.
“At the very least, a tool like this can help us know where and when to collect water samples as an algal bloom is starting,” said one of the paper’s coauthors, Michelle Gierach, a scientist at NASA’s Jet Propulsion Laboratory in Southern California. “It can also drive collaboration between specialists, fostering new ways to conduct the science and deliver decision-support products.”
Today, satellites can detect a variety of clues that signal an algal bloom. A hyperspectral sensor aboard NASA’s Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) satellite, for example, can identify algal communities by their size, shape, and pigment. Other instruments like TROPOMI (Tropospheric Monitoring Instrument) pick up on the faint red glow emitted by species such as K. brevis as they photosynthesize.
The study team, consisting of Gierach, Kelly Luis of NASA JPL, and research data scientist Nick LaHaye of Spatial Informatics Group, brought together findings from five space missions or instruments, including PACE and TROPOMI.
The challenge for them was the quantity of raw data involved. How would AI distinguish between deep water and a coastline? Could it recognize a bloom across different data streams? Would it ever be able to handle inputs from both satellites and sensors in the water?
The team developed a self-supervised machine learning system, designed to learn patterns from multiple kinds of satellite data and compare them with field observations. This approach enables AI to recognize relationships between different data sources without needing any labeling in advance.
The system was trained on satellite data collected in 2018 and 2019. Field and lab measurements were then used to add real-world context to the patterns that the system was recognizing. The scientists evaluated the tool’s performance across later time periods in the same geographic areas. Initial results indicate that it can correctly identify and map harmful blooms, including specific species like K. brevis, performing well even in complex coastal waters swirling with sediment, plants, and runoff.
“Applying self-supervised AI to massive streams of satellite data is rapidly becoming a powerful tool for generating actionable ocean intelligence,” said Nadya Vinogradova Shiffer, lead program scientist at NASA Headquarters in Washington.
The team is now improving the tool with more data from more coastlines and expanding tests to other kinds of water bodies, including lakes, with the goal of making it accessible to decision-makers in coming years.
“The aim of this work is to start to bridge technologies to better serve end users and their needs, from aquaculture to tourism,” Luis said. “To do that, we’re going to bring all our NASA assets to the table.”

Hearing the Heavens - Book Review of The Echoing Universe
Typically when we think of astronomy, we think of pictures of M87 captured on a backyard telescope or the soaring colorful peaks of the Eagle Nebula seen by Hubble. But perhaps the most influential type of astronomy of the last 100+ years doesn’t directly result in the stunning pictures we’re so accustomed to today. It captures radio waves from some of the most interesting objects in the universe. And in her new book, The Echoing Universe: How Radio Astronomy Helps Us See the Invisible, Dr. Emma Chapman, a radio astronomer at the University of Nottingham, tracks how these longest wavelengths of the electromagnetic spectrum have influenced the practice of astronomy and our understanding of our place in the universe.
Breaking the Martian Sound Barrier
Ingenuity, the Mars helicopter, which performed the first controlled, powered flight on another planet, was an excellent demonstration of human ingenuity. But it was just that - a demonstrator. The intention with Ingenuity was simply to prove that we could, in fact, fly on another planet. But now we’ve proved that we can, it’s time to do something more useful with that new ability - like do actual science. A new mission designed to do just that recently passed a critical testing milestone, opening the way for future Mars helicopter missions that will make Ingenuity look like our very first steps.

NASA Releases Technology Priorities to Energize Space Industry
NASA released the 2026 Civil Space Shortfall Ranking list on Wednesday, which integrates more than 400 responses from stakeholders including industry organizations, government agencies, and academia. Shortfalls refer to technology areas requiring further development to meet future exploration, science, and other mission needs. The goal of this document is to rank the space community’s most pervasive shortfalls to help guide NASA’s space technology development and investments.
The greatest technological breakthroughs are built on shared vision. At the intersection of government and industry, we’re poised to use this feedback to accelerate high-risk, high-reward technologies, pushing NASA beyond the cutting edge to enable the near impossible.Greg Stover
Acting associate administrator for NASA’s Space Technology Mission Directorate at the agency’s headquarters in Washington
As NASA lays the foundation for long-term missions to the Moon and paves the way for human exploration on Mars, the top ranked shortfalls reflect the challenges industry is most eager to solve, such as developing infrastructure and capabilities for assets to operate for extended durations in the lunar environment, providing surface mobility and logistics for crew and assets on planetary surfaces, and developing on-board advanced computing capabilities for space operations.
From this year’s public call for feedback, NASA received 454 total external responses. Each response was considered the input of a single individual, not a consolidated response of the organization they represented. The cross-cutting nature of this feedback underscores the importance of public, private partnership to drive U.S. leadership in space technology and energize the space economy.
“This feedback provides an invaluable dataset,” said Angela Krenn, acting chief architect for NASA Technology. “As our process matures, each round of input helps target our resources, ensuring America’s space industry can tackle tomorrow’s greatest challenges. By tapping into the collective expertise of our stakeholders, we turn their insights into fuel for NASA’s next giant leap.”
The 2026 shortfalls process builds on NASA’s first shortfall ranking, which asked participants to rank 187 civil space shortfalls, resulting in an integrated list of technology priorities. Leveraging the feedback provided by stakeholders, this year’s exercise streamlined the process by consolidating the shortfalls into 32 broader, integrated categories. This restructuring maintains the original content’s depth while creating a more efficient and accessible feedback mechanism for participants.
Using the 2026 shortfalls results, NASA Technology selected 40 primary focus areas for its fiscal year 2026 investments. These focus areas combine the quantitative data of the shortfall rankings with considerations from NASA’s Ignition initiatives, science and technology, while establishing paths for collaboration with industry, ensuring relevance with academia, and leveraging overlaps in interests with other government agencies.
The 40 focus areas include several capabilities to enable NASA’s future lunar infrastructure including: landing at the lunar South Pole exploration sites in various illumination conditions with accuracy; excavating and transporting lunar regolith at a scale relevant for a demonstration mission; and providing low power, thermal management, and actuation for distributed surface assets to survive and operate in the lunar environment. The list of 40 focus areas is available on page 10 of the shortfalls document.
