NASA-Assisted Scientists Get Bird’s-Eye View of Population Status
Through the eBird citizen scientist program, millions of birders have recorded their observations of different species and submitted checklists to the Cornell Lab of Ornithology. Through a partnership with NASA, the lab has now used this data to model and map bird population trends for nearly 500 North American species.
Led by Alison Johnston of the University of St. Andrews in Scotland, the researchers reported that 75% of bird species in the study are declining at wide-range scales. And yet this study has some good news for birds. The results, published in Science in May, offer insights and projections that could shape the future conservation of the places where birds make their homes.
“This project demonstrates the power of merging in situ data with NASA remote sensing to model biological phenomena that were previously impossible to document,” said Keith Gaddis, NASA’s Biological Diversity and Ecological Forecasting program manager at the agency’s headquarters in Washington, who was not involved in the study. “This data provides not just insight into the Earth system but also provides actionable guidance to land managers to mitigate biodiversity loss.”

National Park Service / Jane Gamble A team from Cornell, the University of St. Andrews, and the American Bird Conservancy used land imaging data from NASA’s Moderate Resolution Imaging Spectroradiometer (MODIS) instruments to distinguish among such specific bird habitats as open forests, dense shrublands, herbaceous croplands, and forest/cropland mosaics. They also drew on NASA weather information and water data that matched the dates and times when birders made their reports.
When combined with a 14-year set of eBird checklists — 36 million sets of species observations and counts, keyed directly to habitats — the satellite data gave researchers almost a strong foundation to produce a clear picture of the health of bird populations. But there was one missing piece.
Wrestling with Wren Data
While some eBird checklists come from expert birders who’ve hiked deep into wildlife preserves, others are sent in by novices watching bird feeders and doing the dishes. This creates what Cornell statistician Daniel Fink described as “an unstructured, very noisy data set,” complete with gaps in the landscape that birders did not reach and, ultimately, some missing birds.
To account for gaps where birds weren’t counted, the researchers trained machine learning models to fill in the maps based on the remote sensing data. “For every single species — say the rock wren — we’ve created a simulation that mimics the species and a variety of ways that it could respond to changes in the environment,” Johnston said. “Thousands of simulations underlie the results we showed.”
CornellLab eBird The researchers achieved unprecedented resolution, zeroing in on areas 12 miles by 12 miles (27 km by 27 km), the same area as Portland, Oregon. This new population counting method can also be applied to eBird data from other locations, Fink said. “Now we’re using modeling to track bird populations — not seasonally through the year, but acrossthe years — a major milestone,” he added.
“We’ve been able to take citizen science data and, through machine learning methodology, put it on the same footing as traditionally structured surveys, in terms of the type of signal we can find,” said Cornell science product manager Tom Auer. “It will increase the credibility and confidence of people who use this information for precise conservation all over the globe.”
The Up Side
Since 1970, North America has lost one-quarter of its breeding birds, following a global trend of declines across species. The causes range from increased pollution and land development to changing climate and decreased food resources. Efforts to reverse this loss depend on identifying the areas where birds live at highest risk, assessing their populations, and pinpointing locations where conservation could help most.
For 83% of the reported species in the new study, the decline was greatest in spots where populations had previously been most abundant — indicating problems with the habitat.
“Even in species where populations are declining a lot, there are still places of hope, where the populations are going up,” Johnston said. The team found population increases in the maps of 97% of the reported species. “That demonstrates that there’s opportunity for those species.”
“Birds face so many challenges,” said Cornell conservationist Amanda Rodewald. “This research will help us make strategic decisions about making changes that are precise, effective, and less costly. This is transformative. Now we can really drill in and know where specifically we’re going to be able to have the most positive impact in trying to stem bird declines.”

Mission Accomplished! Artemis ROADS III National Challenge Competitors Celebrate their Achievements
The NASA Science Activation program’s Northwest Earth and Space Sciences Pathways (NESSP) team has successfully concluded the 2024–2025 Artemis ROADS III National Challenge, an educational competition that brought real NASA mission objectives to student teams (and reached more than 1,500 learners) across the country. From December 2024 through May 2025, over 300 teams of upper elementary, middle, and high school students from 22 states participated, applying STEM (Science, Technology, Engineering, and Mathematics) skills in exciting and creative ways.
Participants tackled eight Mission Objectives inspired by NASA’s Artemis missions, which aim to return humans to the Moon. Students explored challenges such as:
Designing a water purification system for the Moon inspired by local water cycles Developing a Moon-based agricultural plan based on experimental results Programming a rover to autonomously navigate lunar tunnels Engineering and refining a human-rated water bottle rocket capable of safely returning a “chip-stronaut” to Earth Envisioning their future careers through creative projects like graphic novels or video interviews Exploring NASA’s Artemis program through a new Artemis-themed Lotería game In-person hub events were hosted by Northern Arizona University, Central Washington University, and Montana State University, where teams from Washington, Montana, and Idaho gathered to present their work, collaborate with peers, and experience life on a college campus. Students also had the chance to connect virtually with NASA scientists and engineers through NESSP’s NASA Expert Talks series.
“Artemis ROADS III is NESSP’s eighth ROADS challenge, and I have to say, I think it’s the best one yet. It’s always inspiring to see so many students across the country engage in a truly meaningful STEM experience. I heard from several students and educators that participating in the challenge completely changed their perspective on science and engineering. I believe that’s because this program is designed to let students experience the joy of discovery and invention—driven by both teamwork and personal creativity—that real scientists and engineers love about their work. We also show students the broad range of STEM expertise NASA relies on to plan and carry out a mission like Artemis. Most importantly, it gives them a chance to feel like they are part of the NASA mission, which can be truly transformative.”
– Dr. Darci Snowden, Director, NESSP

Crew members are kicking off operations for several biological experiments that recently launched to the International Space Station aboard NASA’s 32nd SpaceX commercial resupply services mission. These include examining how microgravity affects production of protein by microalgae, testing a microscope to capture microbial activity, and studying genetic activity in biofilms.
Microalgae in microgravity
Sophie’s BioNutrients This ice cream is one of several products made with a protein powder created from Chorella microalgae by researchers for the SOPHONSTER investigation, which looks at whether the stress of microgravity affects the algae’s protein yield. Microalgae are nutrient dense and produce proteins with essential amino acids, beneficial fatty acids, B vitamins, iron, and fiber. These organisms also can be used to make fuel, cooking oil, medications, and materials. Learning more about microalgae growth and protein production in space could support development of sustainable alternatives to meat and dairy. Such alternatives could provide a food source on future space voyages and for people on Earth and be used to make biofuels and bioactive compounds in medicines.
Microscopic motion
Portland State University These swimming microalgae are visible thanks to the Extant Life Volumetric Imaging System or ELVIS, a fluorescent 3D imaging microscope that researchers are testing aboard the International Space Station. The investigation studies both active behaviors and genetic changes of microscopic algae and marine bacteria in response to spaceflight. ELVIS is designed to autonomously capture microscopic motion in 3D, a capability not currently available on the station. The technology could be useful for a variety of research in space and on Earth, such as monitoring water quality and detecting potentially infectious organisms.
Genetics of biofilms
BioServe This preflight image shows sample chambers for the Genetic Exchange in Microgravity for Biofilm Bioremediation (GEM-B2) investigation, which examines the mechanisms of gene transfer within biofilms under microgravity conditions. Biofilms are communities of microorganisms that collect and bind to a surface. They can clog and foul water systems, often leave a residue that can cause infections, and may become resistant to antibiotics. Researchers could use results from this work to develop genetic manipulations that inhibit biofilm formation, helping to maintain crew health and safety aboard the International Space Station and on future missions.

The Mass Spectrometer Observing Lunar Operations (MSolo) for NASA’s Volatile Investigating Polar Exploration Rover (VIPER) mission is prepared for packing inside a laboratory in the Space Station Processing Facility at NASA’s Kennedy Space Center in Florida on Feb. 21, 2023. MSolo is a commercial off-the-shelf mass spectrometer modified to work in space and it will help analyze the chemical makeup of landing sites on the Moon, as well as study water on the lunar surface.NASA/Kim Shiflett A NASA-developed technology that recently proved its capabilities in the harsh environment of space will soon head back to the Moon to search for gases trapped under the lunar surface thanks to a new Cooperative Research and Development Agreement between NASA and commercial company Magna Petra Corp.
The Mass Spectrometer Observing Lunar Operations (MSOLO) successfully demonstrated the full range of its hardware in lunar conditions during the Intuitive Machines 2 mission earlier this year. Under the new agreement, a second MSOLO, mounted on a commercial rover, will launch to the Moon no earlier than 2026. Once on the lunar surface, it will measure low molecular weight volatiles in hopes of inferring the presence of rare isotopes, such as Helium-3, which is theorized to exist, trapped in the regolith, or lunar dust, of the Moon.
“This new mission opportunity will help us determine what volatiles are present in the lunar surface, while also providing scientific insight for Magna Petra’s goals,” said Roberto Aguilar Ayala, research physicist at NASA’s Kennedy Space Center in Florida. “Learning more about the lunar volatiles and their isotopes supports NASA’s goal of sustaining long-term human space exploration. We will need to extract resources locally to enhance the capabilities of our astronauts to further exploration opportunities on the lunar surface.”
The MSOLO instrument will be integrated on a commercial rover, selected by Magna Petra. The rover will allow MSOLO to gather the data needed for researchers to understand which low-molecular weight gases reside within the Moon’s surface.
NASA will work with the partner to integrate MSOLO so that it will function properly with the rover, and the partner will analyze and share data in real time with NASA to understand the location of these volatiles on the Moon and their ability to be extracted in the future.
Magna Petra hopes to understand the presence of Helium-3 isotope within the Moon’s surface, with the ultimate goal of collecting it and bringing it back to Earth for use in a variety of industries, including energy production through nuclear fusion, quantum computing, health care, and specialized laboratory equipment.
The MSOLO instrument began as a commercial off-the-shelf mass spectrometer designed to analyze volatiles used in the manufacturing of semi-conductors, which helped keep NASA’s development costs down. NASA modified the device to withstand the rigors of spaceflight and the Moon’s harsh conditions. On its first journey to the Moon, MSOLO was part of the Polar Resources Ice Mining Experiment 1.
Signed on April 2, the reimbursable agreement is the first of its kind established at NASA Kennedy. Under the agreement, Magna Petra will reimburse NASA for costs such as supporting MSOLO integration and testing with the rover, pre-mission preparation and mission operations of the instruments, and expertise in system engineering, avionics, and software.
“This innovative agreement promises to provide valuable data to both partners,” said Jonathan Baker, chief of Spaceport Development at NASA Kennedy. “This approach demonstrates NASA’s commitment to finding unique ways to work with commercial industry to help advance technology in a fiscally responsible way and enabling innovation for the benefit of humankind.”
Throughout the mission, NASA will retain ownership of MSOLO. Once the mission is complete, the instrument will no longer have access to power and communications and will remain on the surface of the Moon. The valuable data gathered during the mission will be submitted to the Planetary Data System for public dissemination.
