You might think birds skimming over the ocean wouldn’t seek wind unless it was pushing them in the right direction, but NASA-funded researchers have learned that storm petrels find stiff crosswinds worth the slowdown, in return for the clues and cues the gusts carry.
In a paper published by the Royal Society’s Biology Letters May 13, researchers from Woods Hole Oceanographic Institution (WHOI) and the Italian Institute for Environmental Protection and Research (ISPRA) found that Mediterranean storm petrels actively sought out crosswinds, which carried odors the birds used to navigate toward prey. The birds were effectively trading the extra energy needed to fly in a crosswind for the information it blows toward them.
These sparrow-sized birds routinely undertake foraging trips hundreds of miles over the sea, returning to the breeding colony to relieve their partners from incubation duties. Until recently, their small size has precluded researchers’ ability to tag them, keeping their journeys a mystery. In 2020 and 2021, working on the Italian island Sardinia, the team, led by ISPRA and WHOI, attached lightweight GPS sensors to the birds, adding just 3.3% of the birds’ weight as they set out over the Mediterranean Sea.
This finding could help reveal how changing winds might impact seabirds’ feeding, breeding, energy levels, and survival, adding insights about patterns of nutrients in the sea — and the forces that create them.

Sentinel-6 satellite data shows strengthening warm-water waves in the Pacific, pointing to the likely arrival of El Niño and its global weather impacts later in 2026. Several months before an El Niño develops, large waves of warmer, elevated water travel eastward across the Pacific Ocean. Satellite observations in 2026 have detected several of these waves. [...]Scientists have confirmed a rare “impossible” earthquake deep beneath Utah, revealing a hidden source of seismic activity inside Earth’s mantle. Nearly five decades after a puzzling earthquake struck deep beneath northern Utah, scientists have confirmed that the event was real and part of a rare category of earthquakes that occur much deeper underground than researchers [...]
Equipped with rock picks and hand lenses, a team of geoscientists deployed to the Mojave Desert recently to investigate a tantalizing “fingerprint” detected by a NASA sensor. Their target: a cache of topaz hiding in plain sight.
The geologists weren’t searching for gem-grade treasure. Rather, the presence of topaz could hint at a more valuable deposit below of something known as porphyry copper.
One of the world’s primary sources of copper, these deposits are left behind when magma and hot water from deep underground course through Earth’s crust, chemically transforming the surrounding rock. This tends to occur where one tectonic plate dives below another, known as a subduction zone, such as the North American Cordillera, which stretches from the Canadian Rockies to western Mexico.
In addition to copper — the third most used metal in the world after steel and aluminum — the deposits can hold other critical minerals like molybdenum and tellurium, which are used in everything from steelmaking to solar panels. Finding the deposits isn’t easy. Geologists look for topaz because it forms under the same volcanic conditions.
For the team in the Mojave, the goal was to collect more evidence. That would require boots on the ground and a heavy bag of samples. The scientists who converged on the site included three experts from the U.S. Geological Survey (USGS) and Robert Green of NASA’s Jet Propulsion Laboratory in Southern California.
“What we’re doing out here is geologic CSI,” said Green, referring to the investigative TV show, as he split open a weathered red rock to expose a sparkling core. “We’re looking for clues to reconstruct what happened here.”
The sensor that detected the topaz deposit on public land near Barstow, California, was built at JPL. Called AVIRIS, short for Airborne Visible Infrared Imaging Spectrometer, it analyzes reflected sunlight and can be used to identify chemicals and minerals by their unique spectral fingerprint. The technology was pioneered in the early 1980s by a team that included Green, and space-hardened versions have explored the Moon, Mars, and other rocky bodies in the solar system in the decades since.
While its cousins study distant worlds aboard spacecraft, the AVIRIS line of sensors is advancing Earth science from aircraft. The latest model, AVIRIS-5, recently took to the skies for the first time as part of the NASA-USGS Geologic Earth Mapping Experiment (GEMx). The goal of GEMx is to identify sources of critical minerals across the American West, including in the waste rock of active and legacy mines. It is led by the USGS as part of its larger, nationwide initiative.
Since 2023, GEMx flights have covered more than 386,000 square miles (1 million square kilometers) of American soil, including most of California.
Ground-truthing the sensor data can entail hot field work, scrambling over steep crags to uncover samples for lab analysis. While testing has confirmed the topaz discovery, determining if the Mojave site overlies a porphyry copper deposit will require intensive investigation using ground-penetrating equipment. But the AVIRIS finding shows how advanced NASA airborne sensing can help lead geologists to the metaphorical needle in a haystack, even in heavily explored Southern California.
“People have been prospecting this area for generations,” said Erik Tharalson, a USGS geologist. “But there’s a lot more to discover.”
From the beginning, the GEMx mineral mapping campaign has been enabled by one of the highest-flying aircraft in NASA’s fleet: the ER‑2. It deployed on March 31 from NASA’s Armstrong Flight Research Center in Edwards, California, to Colorado Springs Airport in Colorado.
“We deployed to Colorado Springs to maximize flight time for data collection needed in Colorado, Utah, New Mexico, Arizona, and Texas,” said John McGrath, ER‑2 project manager at NASA Armstrong.
By the conclusion of this deployment on June 5, the aircraft had completed 26 flights totaling more than 125 hours. Soaring at about 65,000 feet, the ER-2 can fly at high altitudes that allow it to collect broad‑area, high‑resolution spectral measurements in a single pass, supporting researchers studying mineral composition and surface processes.
In 2025, the aircraft flew 36 science missions, collecting more than 7 billion measurements over 200 flight hours. The data has contributed to the largest airborne surface mineralogy dataset gathered in a single NASA-USGS campaign.
The GEMx survey is led and funded by the USGS Earth Mapping Resources Initiative. Earth MRI is modernizing mapping the nation’s surface and subsurface to find new, critical, and other minerals. It is a partnership effort with 45 state geological surveys, federal agencies, private industry, tribes, universities, and others. The initiative will capitalize on both the technology developed by NASA for spectroscopic imaging, as well as the USGS expertise in analyzing the datasets, conducting field work, and deriving critical mineral information from them.

Rising seas could turn mangroves from carbon-storing climate allies into unexpected carbon emitters. Mangroves are among the most effective natural systems for capturing and storing carbon, but new research suggests that rising sea levels could significantly reduce that benefit and may even cause these coastal forests to release carbon in the future. Made up of [...]Ancient asteroid impacts may have done more than reshape Earth’s surface. For decades, asteroid impacts have been viewed mainly as agents of destruction. But on the young Earth, they may have done something far more surprising: helped create some of the planet’s first habitable environments. A new study from Southwest Research Institute (SwRI) suggests that [...]Scientists have discovered a colossal hidden structure beneath Antarctica that could reshape our understanding of the continent’s past and present. Scientists have identified a massive hidden geological formation beneath East Antarctica, revealing a continent-scale structure buried under some of the thickest ice on Earth.

Last month, Landsat’s very own Jim Irons won the prestigious William T. Pecora Award.
Irons, now an emeritus scientist at NASA Goddard Space Flight Center, played an integral role in shaping the Landsat program into what it is today. He served as deputy project scientist for Landsat 7 before taking over as project scientist for Landsat 8. From the earliest days of Landsat 8—then called the Landsat Data Continuity Mission (LDCM)—all the way through launch and operation, Irons worked across the agency and with colleagues at the USGS to ensure that Landsat continued providing critical data to researchers around the world. He championed rigorous calibration standards and fought to keep the thermal band on Landsat 8. Now, with projects like OpenET relying on evapotranspiration data derived from Landsat thermal imagery, the strength of his vision has only become more apparent.
Irons also served as the director of NASA Goddard’s Earth Science Division during the turbulent early days of the COVID-19 pandemic. Contending with global disruption, he prioritized making sure that everyone had the support that they needed to continue doing great work. As a leader and a scientist, Irons left a legacy of collaboration and innovation that lives on today.
We checked in with Irons about his role in Landsat’s history, what it takes to be a good leader, and winning the Pecora award:
One reason I feel so honored is that prior recipients have been my supervisors, mentors, role models, and colleagues whose work I admired and who inspired me. There’s a long list of people who have been recipients, and I am very honored to be added to that list.
There are also many people who have not yet been recognized who are very deserving. I’ve written letters of support for others, and I hope I’m called on again because there are more people who deserve recognition than there are awards to give out.
Data continuity is the backbone of the Landsat program. We are looking for change over time. When we talk about climate change and the impact of humans on the land surface, those changes are multi-decadal. We wouldn’t be able to understand, characterize, and monitor those changes without a continuous data record.
And it’s really important that the data record is well-calibrated. When we see changes between data from one Landsat sensor relative to another, we need to be confident that it’s a change occurring on the Earth, not a change in the performance of the sensors.
Early in my career, I got in trouble over calibration. NASA was flying an airborne sensor called the Thematic Mapper Simulator, intended to anticipate the capabilities of Landsat 4 and 5. But the operators kept changing the radiometric gain in-flight to maximize the dynamic range. I told NASA Headquarters that we couldn’t compare that data to the actual Thematic Mappers if they kept changing the gain—it wasn’t the same radiometry! The HQ manager got really upset, but I weathered the storm and stuck to my guns.
Later, when Landsat 4 and 5 were returned to the U.S. government from private operation, there had been no real calibration since launch. I advocated for a ground system component at USGS EROS to perform calibration. I didn’t build it, but I did advocate for USGS to hire a brilliant guy named Jim Storey, who developed the software for the precise geolocation of pixels in the data.
When I became Landsat 8 Project Scientist, we needed a pre-launch calibration lead. I advocated for Brian Markham. Brian just did a remarkable job ensuring the calibration of the Operational Land Imager (OLI) and its cross-calibration with previous instruments. He was modest, humble, and built a highly effective team across private industry and agencies.
Back when USGS charged for data, the use of thermal data was minimal. Some well-respected papers even claimed it wouldn’t be possible to use thermal data to estimate evapotranspiration rates. Based on that, the Director of Earth Sciences at NASA HQ was convinced that the thermal capability wasn’t providing a return on investment.
But while this debate was ongoing, people began developing methodologies for estimating evapotranspiration and water consumption using thermal data—prominently Martha Anderson at the USDA, and researchers at the University of Idaho. It became crucial for monitoring agricultural water use in the West, and was even used in adjudicating water rights. It was also useful for cloud detection and fire monitoring.
I felt strongly that dropping the thermal capability was inconsistent with our directive to continue the Landsat data record. However, due to time pressures and budget constraints, the decision was initially made to fly Landsat 8 without a thermal instrument. But then, when our schedule was pushed back by an independent review board, a window opened up. Center Director Ed Weiler, who had moved to HQ, supported putting a thermal sensor on the payload. Kathy Richardson and engineer Fernando Pellerano were assigned to build it on an incredibly tight schedule, and they did an unbelievable job.
Now, deriving evapotranspiration rates for water consumption is considered essential. Ironically, for Landsat 9, NASA HQ even briefly considered launching a satellite with only a thermal sensor!
There were a lot of problems. Laughs. Because of the Land Remote Sensing Policy Act of 1992, the government was exploring commercial data buys for the follow-on mission. NASA spent five painful years attempting to implement LDCM as a commercial data buy. Only one company ultimately responded to the RFP, and it wasn’t a good deal for NASA, so it was rejected.
Then we were directed to put the Landsat sensor on an NPOESS platform (combining civilian and military weather satellite requirements). That platform wasn’t technically suitable, and the program ultimately fell apart.
Finally, the Office of Science and Technology Policy directed us to launch a free-flyer. Bill Ochs took over as project manager, and he deserves so much credit for the success of Landsat 8. He essentially rescued the project and put it on a path to success.
Darrell Williams and I worked very hard to establish a good relationship between NASA Goddard and USGS EROS. I took many trips to Sioux Falls. With Landsat 7, the EROS Center Director at the time, Don Lauer, brought in new people with great experience, like Jim Storey, Doug Daniels, and Jim Nelson. They developed the geometric rectification software for Landsat 7, and by the time we worked on Landsat 8, they had the right people in place to develop the whole data processing system. And we all got along really well with them. We still keep in touch with a number of them and consider them friends.
Yes. A major emerging capability is using Landsat data in concert with other systems, like ESA’s Sentinel-2, or with LIDAR and radar for 3D forest mapping. The community has asked for more frequent observations, especially more frequent thermal observations to measure water consumption more precisely without extrapolating over long gaps during the growing season.
There’s also great interest in using Landsat for water quality assessment, combining it with the PACE mission to monitor coastal and inland water quality. And tracking glacial velocities, glacial retreat, and even population displacement in conflict regions are all expanding areas. Landsat is truly foundational.
I was asked to step up after my predecessor, Piers Sellers—who was an absolute superstar—passed away. My main goal was simply to create an environment where the highly diverse researchers within the division could be successful. I wanted to minimize bureaucratic hindrances so they could focus on their work.
What I learned is that there is a limit to authority. Dictating doesn’t work. You have to lead, engage people, bring them into discussions, and get their buy-in. I used to joke that the job was like working with 1,400 valedictorians! It’s a high-achieving, dedicated group. My challenge was sometimes just reminding them to respect the work of the person down the hall, because people can get so fiercely focused on their own research.
My primary goal during my tenure was to provide stability, especially since it spanned what was then the longest government shutdown in history, followed by the COVID-19 pandemic. I was incredibly impressed by how productive the division remained through a complete disruption in how they worked.
Persistence. Persistence in pursuing your interests is critical. The only reason Landsat 8 was a success was that we persisted through several failed attempts to reformulate the program, schedule challenges, and budget uncertainties.
Funding and mission success aren’t entitlements based on your name or reputation. You have to work hard, keep putting forward proposals, do good work, and persist through rejections. If you really believe in what you’re doing, Goddard is a great place to work. You can get a lot done. But it takes persistence.
