Preparations for Next Moonwalk Simulations Underway (and Underwater)
An aerial view of Palmyra Atoll, where animal tracking data now being studied by NASA’s Internet of Animals project was collected using wildlife tags by partners at The Nature Conservancy, the U.S. Geological Survey, the National Oceanic and Atmospheric Administration, and several universities.The Nature Conservancy/Kydd Pollock 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.

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.
The Palmyra Atoll is a haven for biodiversity, boasting thriving coral reef systems, shallow waters that act as a shark nursery, and rich vegetation for various land animals and seabirds. 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.NASA/Earth Observatory Team “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.”
Tagged Yellowfin Tuna, Grey Reef Sharks, and Great Frigatebirds move in and out of a marine protected area (blue square), which surrounds the Palmyra Atoll (blue circle) in the tropical heart of the Pacific. These species are three of many that rely on the atoll and its surrounding reefs for food and for nesting.NASA/Lauren Dauphin 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.
Research scientist Morgan Gilmour checks on a young great frigatebird in its nest. The marine protected area around Palmyra Atoll protects these birds’ breeding grounds.UC Santa Barbara/Devyn Orr 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.

NASA Mission to Study Mysteries in the Origin of Solar Radio Waves
NASA’s CubeSat Radio Interferometry Experiment, or CURIE, is scheduled to launch July 9, 2024, to investigate the unresolved origins of radio waves coming from the Sun.
CURIE will investigate where solar radio waves originate in coronal mass ejections, like this one seen in 304- and 171-angstrom wavelengths by NASA’s Solar Dynamics Observatory. NASA/Goddard Space Flight Center Scientists first noticed these radio waves decades ago, and over the years they’ve determined the radio waves come from solar flares and giant eruptions on the Sun called coronal mass ejections, or CMEs, which are a key driver of space weather that can impact satellite communications and technology at Earth. But no one knows where the radio waves originate within a CME.
The CURIE mission aims to advance our understanding using a technique called low frequency radio interferometry, which has never been used in space before. This technique relies on CURIE’s two independent spacecraft — together no bigger than a shoebox — that will orbit Earth about two miles apart. This separation allows CURIE’s instruments to measure tiny differences in the arrival time of radio waves, which enables them to determine exactly where the radio waves came from.
“This is a very ambitious and very exciting mission,” said Principal Investigator David Sundkvist, a researcher at the University of California, Berkeley. “This is the first time that someone is ever flying a radio interferometer in space in a controlled way, and so it’s a pathfinder for radio astronomy in general.”
CURIE team members work on integrating the satellites into the CubeSat deployer. ExoLaunch The spacecraft, designed by a team from UC Berkeley, will measure radio waves ranging 0.1 to 19 megahertz to pinpoint the radio waves’ solar origin. These wavelengths are blocked by Earth’s upper atmosphere, so this research can only be done from space.
CURIE will launch aboard an ESA (European Space Agency) Ariane 6 rocket in early July from the Guiana Space Center in Kourou, French Guiana. The rocket will take CURIE to 360 miles above Earth’s surface, where it can get a clear view of the Sun’s radio waves.
Once in its circular orbit, the two adjoined CURIE spacecraft will establish communication with ground stations before orienting and separating. When the separated satellites are in formation, their dual eight-foot antennas will deploy and start collecting data.
CURIE is sponsored by NASA’s Heliophysics Flight Opportunities for Research and Technology (H-FORT) Program and is the sole mission manifested on the NASA CubeSat Launch Initiative’s ELaNa (Educational Launch of Nanosatellites) 43 mission. As a pathfinder, CURIE will demonstrate a proof-of-concept for space-based radio interferometry in the CubeSat form factor. CURIE will also pave the way for the upcoming Sun Radio Interferometer Space Experiment, or SunRISE, mission. SunRISE will employ six CubeSats to map the region where the solar radio waves originate in 2-D.

Aurora and airglow are seen from the International Space Station in 2015.Credits: NASA/JSC/ESRS NASA has selected three proposals for concept studies of missions to investigate the complex system of space weather that surrounds our planet and how it’s connected to Earth’s atmosphere.
The three concepts propose how to enact the DYNAMIC (Dynamical Neutral Atmosphere-Ionosphere Coupling) mission, which was recommended by the 2013 Decadal Survey for Solar and Space Physics. The DYNAMIC mission is designed to study how changes in Earth’s lower atmosphere influence our planet’s upper atmosphere, where space weather like auroras and satellite disruptions are manifested. This knowledge will benefit humanity by helping us understand how space weather can interfere with crucial technology like navigation systems and satellites.
“Earth and space are an interconnected system that reaches from the heart of our solar system, the Sun, to the lowest reaches of the atmosphere where we live and extends to the edge of our heliosphere – the boundary of interstellar space,” said Nicola Fox, associate administrator, Science Mission Directorate at NASA Headquarters in Washington. “While space weather can spark the beautiful auroras across our skies, it also has the potential to cause disruptions for us here on Earth and can be dangerous for our spacecraft and astronauts in space. The DYNAMIC mission will expand our understanding of how Earth itself shapes space weather events that influence our home planet.”
The DYNAMIC mission is designed to make measurements within Earth’s upper atmosphere between about 50-125 miles (80-200 kilometers) in altitude. With multiple spacecraft, DYNAMIC’s simultaneous observations from different locations can give scientists a more complete picture of how waves propagate upwards through this part of the atmosphere.
NASA’s fiscal year 2023 appropriation directed NASA to initiate this first phase of study. As the first step of a two-step selection process, each proposal will receive $2 million for a concept study. NASA solicited missions with a cost cap of $250 million, which does not include the launch. The studies will last nine months.
The selected concept teams are:
University of Colorado, Boulder, led by principal investigator Tomoko Matsuo Key partners include Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland; NASA’s Jet Propulsion Laboratory in Southern California; and Massachusetts Institute of Technology’s Haystack Observatory in Westford, Massachusetts.
University of Colorado, Boulder, led by principal investigator Aimee Merkel Key partners include BAE Systems in Westminster, Colorado, and the Naval Research Laboratory in Washington.
Virginia Polytechnic Institute and State University, led by principal investigator Scott Bailey Key partners include Southwest Research Institute in San Antonio, Texas, Space Dynamics Laboratory in Logan, Utah, Global Atmospheric Technologies and Sciences in Newport News, Virginia, and Computational Physics, Inc. in Boulder, Colorado.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
Satellites continuously peer down from orbit to take measurements of Earth, and this week a group of scientists set sail to verify some of those data points.
On June 2, the SCOAPE (Satellite Coastal and Oceanic Atmospheric Pollution Experiment) research team, in partnership with the U.S. Interior Department’s Bureau of Ocean Energy Management, took to the seas in the Gulf of Mexico for its second campaign to make surface-based measurements of air pollutants.
The NASA/GSFC SCOAPE team launches an ozonesonde weather balloon from the stern of the research vessel Point Sur during the May 2019 cruise. Ryan Stauffer (NASA/GSFC) The primary pollutant scientists are measuring is nitrogen dioxide (NO2), the compound that reacts with sunlight to make ground-level ozone, said Anne Thompson, senior scientist emeritus for atmospheric chemistry at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, and senior researcher at the University of Maryland, Baltimore County.
The Gulf of Mexico is highly concentrated with oil and natural gas drilling platforms, which are sources of NO2. By taking measurements of these emissions from the sea surface nearby, scientists can help validate measurements taken from a much different vantage point. The research vessel the scientists are using, Point Sur, is owned by the University of Southern Mississippi and operated by the Louisiana Universities Marine Consortium.

Ryan Stauffer (NASA/GSFC) “We’re the eyes on the surface to understand how well the eyes in the sky are working,” said Ryan Stauffer, research scientist for the atmospheric chemistry and dynamics laboratory at Goddard. Stauffer is also the principal investigator for the SCOAPE II project.
For the first iteration of the project in 2019, ship-based measurements were compared to data gathered by the Ozone Monitoring Instrument aboard NASA’s Aura satellite and the Tropospheric Monitoring Instrument aboard ESA’s (European Space Agency) Sentinel-5 Precursor satellite. Both instruments fly on polar orbiting satellites, which pass over every part of the globe once per day. They capture snapshots at the same time each day, but cannot capture the short-lived NO2 emissions that come and go at different times.
In 2024, the research team is working to validate the measurements taken by TEMPO (the Tropospheric Emissions: Monitoring of Pollution instrument), which was launched on a commercial satellite in April 2023. The TEMPO instrument provides a different perspective to the NO2 measurements due to its geostationary orbit — it focuses solely on North America and has a constant view of the Gulf of Mexico region. This allows scientists to better quantify emissions and make comparisons across all daylight hours.
From space, satellites collect measurements of the “total column” of air, which means they measure the concentrations of NO2 from the land or ocean surface all the way up to the top of the atmosphere. With SCOAPE, scientists are taking measurements from the ship, about 33 feet above sea level, to focus measurements on the air that people breathe.
The SCOAPE Pandora spectrometer instrument, which were used to gather the air quality near the operation sites, during sunset with a shallow water gas platform on the horizon.Ryan Stauffer (NASA/GSFC) Learning more about how those surface measurements compare to what satellites see in the total column can help scientists figure out how to use satellite data most effectively. Measuring NO2 from space over the past two decades has helped scientists understand how the compound affects air quality, and has helped to inform policies to reduce emissions of the pollutant.
During SCOAPE’s 2019 campaign, researchers detected concentrations of methane – a significant greenhouse gas – near the Gulf Coast. This time around, the scientists are looking to accurately measure these concentrations from the surface as well. They will mount the NASA Airborne Visible and InfraRed Imaging Spectrometer–3 imaging spectrometer instrument on a Dynamic Aviation B-200 plane to collect methane measurements above the Gulf, which will add an extra layer to understanding emissions of this potent greenhouse gas from Gulf of Mexico oil and gas operations.
It has historically been difficult to measure methane from space, but scientists are working to build those capabilities. As with NO2, taking surface measurements helps scientists better understand the measurements taken from space.
