Anchoring the boat in a sandbar, research scientist Morgan Gilmour steps into the shallows and is immediately surrounded by sharks. The warm waters around the tropical island act as a reef shark nursery, and these baby biters are curious about the newcomer. They zoom close and veer away at the last minute, as Gilmour slowly makes her way toward the kaleidoscope of green sprouting from the island ahead.

Gilmour, a scientist at NASA’s Ames Research Center in California’s Silicon Valley, conducts marine ecology and conservation studies using data collected by the U.S. Geological Survey (USGS) from animals equipped with wildlife tags. Palmyra Atoll, a United States marine protected area, provides the perfect venue for this work.

A collection of roughly 50 small islands in the tropical heart of the Pacific Ocean, the atoll is bursting with life of all kinds, from the reef sharks and manta rays circling the shoreline to the coconut crabs climbing palm branches and the thousands of seabirds swooping overhead. By analyzing the movements of dolphins, tuna, and other creatures, Gilmour and her collaborators can help assess whether the boundaries of the marine protected area surrounding the atoll actually protect the species they intend to, or if its limits need to shift.

Launched in 2020 by The Nature Conservancy and its partners – USGS, NOAA (National Oceanic and Atmospheric Administration), and several universities – the project team deployed wildlife tags at Palmyra in 2022, when Gilmour was a scientist with USGS.

Now with NASA, she is leveraging the data for a study under the agency’s Internet of Animals project. By combining information transmitted from wildlife tags with information about the planet collected by satellites – such as NASA’s Aqua, NOAA’s GOES (Geostationary Operational Environmental Satellite) satellites, and the U.S.-European Jason-3 – scientists can work with partners to draw conclusions that inform ecological management.

A satellite image shows a a collection of islands in various shades of green, stretching roughly in two parallel lines from left to right. On the top line, a thin layer of whitewater denotes where the reefs are. Bright teal surrounds the islands where the water is shallowest, fading quickly into the deep blue ocean water composing the majority of the image.

In the Landsat image above, a small white square marks the research station, where scientists from all over the world come to study the many species that call the atoll home.

“Internet of Animals is more than just an individual collection of movements or individual studies; it’s a way to understand the Earth at large,” said Ryan Pavlick, then Internet of Animals project scientist at NASA’s Jet Propulsion Laboratory in Southern California, during the project’s kickoff event.

The Internet of Animals at Palmyra

“Our work at Palmyra was remarkably comprehensive,” said Gilmour. “We tracked the movements of eight species at once, plus their environmental conditions, and we integrated climate projections to understand how their habitat may change. Where studies may typically track two or three types of birds, we added fish and marine mammals, plus air and water column data, for a 3D picture of the marine protected area.”

Now, the NASA team has put that data into a species distribution model, which combines the wildlife tracking information with environmental data from satellites, including sea surface temperature, chlorophyll concentration, and ocean current speed. The model can help researchers understand how animal populations use their habitats and how that might shift as the climate changes.

Preliminary results from Internet of Animals team show that the animals tracked are moving beyond the confines of the Palmyra marine protected area. The model identified suitable habitats both in and around the protected zone – now and under predicted climate change scenarios – other researchers and decisionmakers can utilize that knowledge to inform marine policy and conservation.

Following a 2023 presidential memorandum, NOAA began studying and gathering input on whether to expand the protected areas around Palmyra and other parts of the Pacific Remote Islands Marine National Monument. Analysis from NASA’s Internet of Animals could inform that and similar decisions, such as whether to create protected “corridors” in the ocean to allow for seasonal migrations of wildlife. The findings and models from the team’s habitat analysis at Palmyra also could help inform conservation at similar latitudes across the planet.

Beyond the Sea: Other Internet of Animals Studies

Research at Palmyra Atoll is just one example of work by Internet of Animals scientists.

Claire Teitelbaum, a researcher with the Bay Area Environmental Research Institute based at NASA Ames, studies avian flu in wild waterfowl, investigating how their movement may contribute to transmission of the virus to poultry and other domestic livestock.

Teams at Ames and JPL are also working with USGS to create next-generation wildlife tags and sensors. Low-power radar tags in development at JPL would be lightweight enough to track small birds. Ames researchers plan to develop long-range radio tags capable of maximizing coverage and transmission of data from high-flying birds. This could help researchers take measurements in hard-to-reach layers of the atmosphere.

With the technology brought together by the Internet of Animals, even wildlife can take an active role in the study of Earth’s interacting systems, helping human experts learn more about our planet and how best to confront the challenges facing the natural world.

      Preparations for Next Moonwalk Simulations Underway (and Underwater)
      This artist’s concept shows a brown dwarf — an object larger than a planet but not massive enough to kickstart fusion in its core like a star. Brown dwarfs are hot when they form and may glow like this one, but over time they get closer in temperature to gas giant planets like Jupiter. NOIRLab/NSF/AURA/R. Proctor An unusual cosmic object is helping scientists better understand the chemistry hidden deep in Jupiter and Saturn’s atmospheres — and potentially those of exoplanets.
      Why has silicon, one of the most common elements in the universe, gone largely undetected in the atmospheres of Jupiter, Saturn, and gas planets like them orbiting other stars? A new study using observations from NASA’s James Webb Space Telescope sheds light on this question by focusing on a peculiar object that astronomers discovered by chance in 2020 and called “The Accident.”
      The results were published on Sept. 4 in the journal Nature.
      As shown in this graphic, brown dwarfs can be far more massive than even large gas planets like Jupiter and Saturn. However, they tend to lack the mass that kickstarts nuclear fusion in the cores of stars, causing them to shine. NASA/JPL-Caltech The Accident is a brown dwarf, a ball of gas that’s not quite a planet and not quite a star. Even among its already hard-to-classify peers, The Accident has a perplexing mix of physical features, some of which have been previously seen in only young brown dwarfs and others seen only in ancient ones. Because of those features, it slipped past typical detection methods before being discovered five years ago by a citizen scientist participating in Backyard Worlds: Planet 9. The program lets people around the globe look for new discoveries in data from NASA’s now-retired NEOWISE (Near-Earth Object Wide-field Infrared Survey Explorer), which was managed by NASA’s Jet Propulsion Laboratory in Southern California.
      The brown dwarf nicknamed “The Accident” can be seen moving in the bottom left corner of this video, which shows data from NASA’s now-retired NEOWISE (Near-Earth Object Wide-Field Infrared Survey Explorer), launched in 2009 with the moniker WISE. NASA/JPL-Caltech/Dan Caselden   The Accident is so faint and odd that researchers needed NASA’s most powerful space observatory, Webb, to study its atmosphere. Among several surprises, they found evidence of a molecule they couldn’t initially identify. It turned out to be a simple silicon molecule called silane (SiH4). Researchers have long expected — but been unable — to find silane not only in our solar system’s gas giants, but also in the thousands of atmospheres belonging to brown dwarfs and to the gas giants orbiting other stars. The Accident is the first such object where this molecule has been identified.
      Scientists are fairly confident that silicon exists in Jupiter and Saturn’s atmospheres but that it is hidden. Bound to oxygen, silicon forms oxides such as quartz that can seed clouds on hot gas giants, bearing a resemblance to dust storms on Earth. On cooler gas giants like Jupiter and Saturn, these types of clouds would sink far beneath lighter layers of water vapor and ammonia clouds, until any silicon-containing molecules are deep in the atmosphere, invisible even to the spacecraft that have studied those two planets up close.
      Some researchers have also posited that lighter molecules of silicon, like silane, should be found higher up in these atmospheric layers, left behind like traces of flour on a baker’s table. That such molecules haven’t appeared anywhere except in a single, peculiar brown dwarf suggests something about the chemistry occurring in these environments.
      “Sometimes it’s the extreme objects that help us understand what’s happening in the average ones,” said Faherty, a researcher at the American Museum of Natural History in New York City, and lead author on the new study.
      Happy accident
      Located about 50 light-years from Earth, The Accident likely formed 10 billion to 12 billion years ago, making it one of the oldest brown dwarfs ever discovered. The universe is about 14 billion years old, and at the time that The Accident developed, the cosmos contained mostly hydrogen and helium, with trace amounts of other elements, including silicon. Over eons, elements like carbon, nitrogen, and oxygen forged in the cores of stars, so planets and stars that formed more recently possess more of those elements.
      Webb’s observations of The Accident confirm that silane can form in brown dwarf and planetary atmospheres. The fact that silane seems to be missing in other brown dwarfs and gas giant planets suggests that when oxygen is available, it bonds with silicon at such a high rate and so easily, virtually no silicon is left over to bond with hydrogen and form silane.
      So why is silane in The Accident? The study authors surmise it is because far less oxygen was present in the universe when the ancient brown dwarf formed, resulting in less oxygen in its atmosphere to gobble up all the silicon. The available silicon would have bonded with hydrogen instead, resulting in silane.
      “We weren’t looking to solve a mystery about Jupiter and Saturn with these observations,” said JPL’s Peter Eisenhardt, project scientist for the WISE (Wide-field Infrared Survey Explorer) mission, which was later repurposed as NEOWISE. “A brown dwarf is a ball of gas like a star, but without an internal fusion reactor, it gets cooler and cooler, with an atmosphere like that of gas giant planets. We wanted to see why this brown dwarf is so odd, but we weren’t expecting silane. The universe continues to surprise us.”
      Brown dwarfs are often easier to study than gas giant exoplanets because the light from a faraway planet is typically drowned out by the star it orbits, while brown dwarfs generally fly solo. And the lessons learned from these objects extend to all kinds of planets, including ones outside our solar system that might feature potential signs of habitability. 
      “To be clear, we’re not finding life on brown dwarfs,” said Faherty. “But at a high level, by studying all of this variety and complexity in planetary atmospheres, we’re setting up the scientists who are one day going to have to do this kind of chemical analysis for rocky, potentially Earth-like planets. It might not specifically involve silicon, but they’re going to get data that is complicated and confusing and doesn’t fit their models, just like we are. They’ll have to parse all those complexities if they want to answer those big questions.”

      6 Min Read Upcoming Launch to Boost NASA’s Study of Sun’s Influence Across Space
      Soon, there will be three new ways to study the Sun’s influence across the solar system with the launch of a trio of NASA and National Oceanic and Atmospheric Administration (NOAA) spacecraft. Expected to launch no earlier than Tuesday, Sept. 23, the missions include NASA’s IMAP (Interstellar Mapping and Acceleration Probe), NASA’s Carruthers Geocorona Observatory, and NOAA’s SWFO-L1 (Space Weather Follow On-Lagrange 1) spacecraft. 
      The three missions will launch together aboard a SpaceX Falcon 9 rocket from NASA’s Kennedy Space Center in Florida. From there, the spacecraft will travel together to their destination at the first Earth-Sun Lagrange point (L1), around one million miles from Earth toward the Sun.
      The missions will each focus on different effects of the solar wind — the continuous stream of particles emitted by the Sun — and space weather — the changing conditions in space driven by the Sun — from their origins at the Sun to their farthest reaches billions of miles away at the edge of our solar system. Research and observations from the missions will help us better understand the Sun’s influence on Earth’s habitability, map our home in space, and protect satellites and voyaging astronauts and airline crews from space weather impacts. 
      The IMAP and Carruthers missions add to NASA’s heliophysics fleet of spacecraft. Together, NASA’s heliophysics missions study a vast, interconnected system from the Sun to the space surrounding Earth and other planets to the farthest limits of the Sun’s constantly flowing streams of solar wind. The SWFO-L1 mission, funded and operated by NOAA, will be the agency’s first satellite designed specifically for and fully dedicated to continuous, operational space weather observations.
      Mapping our home in space: IMAP
      The IMAP mission will study the heliosphere, our home in space.
      NASA/Princeton University/Patrick McPike As a modern-day celestial cartographer, IMAP will investigate two of the most important overarching issues in heliophysics: the interaction of the solar wind at its boundary with interstellar space and the energization of charged particles from the Sun.
      The IMAP mission will principally study the boundary of our heliosphere — a huge bubble created by the solar wind that encapsulates our solar system — and study how the heliosphere interacts with the local galactic neighborhood beyond. The heliosphere protects the solar system from dangerous high-energy particles called galactic cosmic rays. Mapping the heliosphere’s boundaries helps scientists understand our home in space and how it came to be habitable. 
      “IMAP will revolutionize our understanding of the outer heliosphere,” said David McComas, IMAP mission principal investigator at Princeton University in New Jersey. “It will give us a very fine picture of what’s going on out there by making measurements that are 30 times more sensitive and at higher resolution than ever before.”
      The IMAP mission will also explore and chart the vast range of particles in interplanetary space. The spacecraft will provide near real-time observations of the solar wind and energetic particles, which can produce hazardous conditions not only in the space environment near Earth, but also on the ground. The mission’s data will help model and improve prediction capabilities of the impacts of space weather ranging from power-line disruptions to loss of satellites. 
      Imaging Earth’s exosphere: Carruthers Geocorona Observatory
      An illustration shows the Carruthers Geocorona Observatory spacecraft. NASA/BAE Systems Space & Mission Systems The Carruthers Geocorona Observatory, a small satellite, will launch with IMAP as a rideshare. The mission was named after Dr. George Carruthers, creator of the Moon-based telescope that captured the first images of Earth’s exosphere, the outermost layer of our planet’s atmosphere. 
      The Carruthers mission will build upon Dr. Carruthers’ legacy by charting changes in Earth’s exosphere. The mission’s vantage point at L1 offers a complete view of the exosphere not visible from the Moon’s relatively close distance to Earth. From there, it will address fundamental questions about the nature of the region, such as its shape, size, density, and how it changes over time.
      The exosphere plays an important role in Earth’s response to space weather, which can impact our technology, from satellites in orbit to communications signals in the upper atmosphere or power lines on the ground. During space weather storms, the exosphere mediates the energy absorption and release throughout the near-Earth space environment, influencing strength of space weather disturbances. Carruthers will help us better understand the fundamental physics of our exosphere and improve our ability to predict the impacts of the Sun’s activity.
      “We’ll be able to create movies of how this atmospheric layer responds when a solar storm hits, and watch it change with the seasons over time,” said Lara Waldrop, the principal investigator for the Carruthers Geocorona Observatory at the University of Illinois at Urbana-Champaign. 
      New space weather station: SWFO-L1
      SWFO-L1 will provide real-time observations of the Sun’s corona and solar wind to help forecast the resulting space weather.
      NOAA/BAE Systems Space & Mission Systems Distinct from NASA’s research satellites, SWFO-L1 will be an operational satellite, designed to observe solar activity and the solar wind in real time to provide critical data in NOAA’s mission to protect the nation from environmental hazards. SWFO-L1 will serve as an early-warning beacon for potentially damaging space weather events that could impact our technology on Earth. SWFO-L1 will observe the Sun’s outer atmosphere for large eruptions, called coronal mass ejections, and measure the solar wind upstream from Earth with a state-of-the-art suite of instruments and processing system.
      This mission is the first of a new generation of NOAA space weather observatories dedicated to 24/7 operations, working to avoid gaps in continuity. 
      “SWFO-L1 will be an amazing deep-space mission for NOAA,” said Dimitrios Vassiliadis, SWFO program scientist at NOAA. “Thanks to its advantageous location at L1, it will continuously monitor the solar atmosphere while measuring the solar wind and its interplanetary magnetic fields well before it impacts Earth — and transmit these data in record time.”
      With SWFO-L1’s enhanced performance, unobstructed views, and minimal delay between observations and data return, NOAA’s Space Weather Prediction Center forecasters will give operators improved lead time required to take precautionary actions that protect vital infrastructure, economic interests, and national security on Earth and in space.

      NASA science and American industry have worked hand-in-hand for more than 60 years, transforming novel technologies created with NASA research into commercial products like cochlear implants, memory-foam mattresses, and more. Now, a NASA-funded device for probing the interior of storm systems has been made a key component of commercial weather satellites.
      The novel atmospheric sounder was originally developed for NASA’s TROPICS (short for Time-Resolved Observations of Precipitation structure and storm Intensity with a Constellation of SmallSats), which launched in 2023. Boston-based weather technology company Tomorrow.io integrated the same instrument design into some of its satellites.
      NASA’s TROPICS instrument. TROPICS pioneered a novel, compact atmospheric sound now flying aboard a fleet of commercial small satellites created by the weather technology company Tomorrow.io.Credit: Blue Canyon Technologies Atmospheric sounders allow researchers to gather data describing humidity, temperature, and wind speed — important factors for weather forecasting and atmospheric analysis. From low-Earth orbit, these devices help make air travel safer, shipping more efficient, and severe weather warnings more reliable.
      Novel tools for Observing Storm Systems
      In the early 2000s, meteorologists and atmospheric chemists were eager to find a new science tool that could peer deep inside storm systems and do so multiple times a day. At the same time, CubeSat constellations (groupings of satellites each no larger than a shoebox) were emerging as promising, low-cost platforms for increasing the frequency with which individual sensors could pass over fast-changing storms, which improves the accuracy of weather models.
      The challenge was to create an instrument small enough to fit aboard a satellite the size of a toaster, yet powerful enough to observe the innermost mechanisms of storm development. Preparing these technologies required years of careful development that was primarily supported by NASA’s Earth Science Division.
      William Blackwell and his team at MIT Lincoln Laboratory in Cambridge, Massachusetts, accepted this challenge and set out to miniaturize vital components of atmospheric sounders. “These were instruments the size of a washing machine, flying on platforms the size of a school bus,” said Blackwell, the principal investigator for TROPICS. “How in the world could we shrink them down to the size of a coffee mug?”
      With a 2010 award from NASA’s Earth Science Technology Office (ESTO), Blackwell’s team created an ultra-compact microwave receiver, a component that can sense the microwave radiation within the interior of storms.
      The Lincoln Lab receiver weighed about a pound and took up less space than a hockey puck. This innovation paved the way for a complete atmospheric sounder instrument small enough to fly aboard a CubeSat. “The hardest part was figuring out how to make a compact back-end to this radiometer,” Blackwell said. “So without ESTO, this would not have happened. That initial grant was critical.”
      In 2023, that atmospheric sounder was sent into space aboard four TROPICS CubeSats, which have been collecting torrents of data on the interior of severe storms around the world.
      Transition to Industry
      By the time TROPICS launched, Tomorrow.io developers knew they wanted Blackwell’s microwave receiver technology aboard their own fleet of commercial weather satellites. “We looked at two or three different options, and TROPICS was the most capable instrument of those we looked at,” said Joe Munchak, a senior atmospheric data scientist at Tomorrow.io.
      In 2022, the company worked with Blackwell to adapt his team’s design into a CubeSat platform about twice the size of the one used for TROPICS. A bigger platform, Blackwell explained, meant they could bolster the sensor’s capabilities.
      “When we first started conceptualizing this, the 3-unit CubeSat was the only game in town. Now we’re using a 6-unit CubeSat, so we have room for onboard calibration,” which improves the accuracy and reliability of gathered data, Blackwell said.
      Tomorrow.io’s first atmospheric sounders, Tomorrow-S1 and Tomorrow-S2, launched in 2024. By the end of 2025, the company plans to have a full constellation of atmospheric sounders in orbit. The company also has two radar instruments that were launched in 2023 and were influenced by NASA’s RainCube instrument — the first CubeSat equipped with an active precipitation radar.
      More CubeSats leads to more accurate weather data because there are more opportunities each day — revisits — to collect data. “With a fleet size of 18, we can easily get our revisit rate down to under an hour, maybe even 40 to 45 minutes in most places. It has a huge impact on short-term forecasts,” Munchak said.
      Having access to an atmospheric sounder that had already flown in space and had more than 10 years of testing was extremely useful as Tomorrow.io planned its fleet. “It would not have been possible to do this nearly as quickly or nearly as affordably had NASA not paved the way,” said Jennifer Splaingard, Tomorrow.io’s senior vice president for space and sensors.
      A Cycle of Innovation
      The relationship between NASA and industry is symbiotic. NASA and its grantees can drive innovation and test new tools, equipping American businesses with novel technologies they may otherwise be unable to develop on their own. In exchange, NASA gains access to low-cost data sets that can supplement information gathered through its larger science missions.
      Tomorrow.io was among eight companies selected by NASA’s Commercial SmallSat Data Acquisition (CSDA) program in September 2024 to equip NASA with data that will help improve weather forecasting models. “It really is a success story of technology transfer. It’s that sweet spot, where the government partners with tech companies to really take an idea, a proven concept, and run with it,” Splaingard said.

      If you asked someone what they expected to see during a visit to NASA’s Johnson Space Center, they would probably list things like astronauts, engineers, and maybe a spacecraft or two. It might be a surprise to learn you can also spy hundreds of species of animals – from geckos and snakes to white-tailed deer and red-tailed hawks.

      Ensuring those species and Johnson’s workforce can safely coexist is the main job of Matt Strausser, Johnson’s senior biologist for wildlife management. Strausser works to reduce the negative impacts animals can have on Johnson’s operations as well as the negative impact humans might have on native wildlife and their habitats.

      NASA’s Johnson Space Center Senior Biologist Matt Strausser leads a nature hike to Johnson staff that detailed the native plant species and wildlife onsite, invasive species, and mitigation efforts.NASA/Lauren Harnett Strausser joined NASA in 2012, fresh out of graduate school, when he was hired on a six-month contract to write Johnson’s first Wildlife Management Plan. “My contract was extended a couple of times until I became a regular part of the facilities service contract, which is where I still am today,” he said.

      Strausser remembers being interested in natural resources from a young age. “I spent a lot of my childhood poring through copies of National Geographic, hiking, and camping,” he said. When it was time for college, Strausser decided to study biology and natural resource management. He spent his summers in jobs or internships that mostly involved endangered wildlife species, including Attwater’s prairie chickens, which are bred at Johnson through a partnership with the Houston Zoo. Strausser noted that he conducted research across the country while he was a student, and even studied fish for a short time in the South Pacific.

      “After all of those adventures in faraway places, I find it ironic that I ended up about 20 miles from where I grew up,” he said. “Once I got onsite, it did not take me long to find that this property has great remnant native plant communities, a fascinating land use history, and some unique natural resource challenges that come from the work done here. Those factors really drew me in and helped motivate me to build a career at Johnson.”

      Matthew Strausser received a Silver Snoopy Award through NASA’s Space Flight Awareness Program in 2018, in recognition of his efforts to prevent and mitigate ant-inflicted damage to critical infrastructure electrical systems.

First, he gathers data about Johnson’s wildlife populations and their habitats. “I use population counts, conflict records, satellite and aerial imagery, nest surveys, outside reports, and even historical data to get an understanding of what’s on the landscape and what problems we have to tackle,” he said.

      With that information, Strausser works to engage project and facility managers and provide recommendations on how to prevent or reduce the impact of wildlife problems onsite. Strausser works with Johnson’s facilities maintenance group to modify buildings to keep animals on the outside, and he gets support from the Johnson veterinarian on animal health issues. He also works closely with Johnson’s pest control and groundskeeping contracts, as their work is often adjacent to wildlife management.

      He supports the safety team, as well. “Our security contractors are a great resource for reporting wildlife issues as well as helping address them,” Strausser said, adding that some of Johnson’s safety groups “have been really helpful at getting the word out about how to stay safe around our wildlife” in coordination with the center’s internal communications team.  His team also responds to wildlife conflict calls, which often involve capturing and relocating animals that have wandered into areas where they pose a risk to people or operations.

      Additionally, Strausser runs the facilities contract’s small unmanned aircraft system, which uses drones to conduct facility inspections, support hurricane response, and survey on-site wildlife.

NASA The nature of his work has instilled in Strausser an appreciation for teamwork and collaboration among colleagues with distinct experiences. Each of the projects he works on involves team members from different organizations and contracts, and most of them do not have a background in biology. “Building a wildlife and natural resource program from the ground up and bringing all of these once-disconnected and diverse professionals together to effectively address problems – that is the achievement I take the most pride in,” he said.

      Strausser observed that accomplishing the goals of the agency’s Artemis campaign will require a tremendous amount of specialized support infrastructure, and that developing and running that infrastructure will require a wide variety of professionals. “It is going to require students and specialists with all different types of backgrounds, passions, and talents.”

      Overall, Strausser said he has a very dynamic job. “Wildlife issues tend to be very seasonal, so throughout the year, the types of issues I am addressing change,” he said. “On top of that, there are always new projects, problems, and questions out there that keep the work fresh and challenging.” He has learned the value of being open to new challenges and learning new skills. “Being adaptable can be just as important as mastery in a specific field,” he said.
