Surf, Turf, Above Earth: Students Participate in NASA Field Research
Flying over and tromping through watery landscapes along the East Coast, working alongside NASA scientists, and recording measurements about the air that they’re travelling through – these are not the usual experiences for an undergraduate student. For the 2023 participants in NASA’s SARP East program – short for Student Airborne Research Program – it was part of a summer they won't forget.
NASA Student Airborne Research Program 2023: Sky-High Science Learning
NASA’s Armstrong Flight Research Center hosted undergraduate students for the 2023 Student Airborne Research Program. An eight-week summer internship program, SARP offers upper-level undergraduate students the opportunity to acquire hands-on research experience as part of a real scientific campaign. This year SARP, the Student Airborne Research Program, celebrated 15 years of success in the Airborne Science Program. Students worked alongside scientists and aircraft professionals both on the ground and in the sky, using NASA Airborne Science Program’s flying science laboratories, like NASA Armstrong’s DC-8 aircraft. Outfitted specifically for science research projects, aircraft like the DC-8 help support both students and mission personnel to investigate science questions, aid in the understanding of our environment, and improve life on Earth.

Global Collaboration Leads to New Discoveries in Lightning Research
With operations based out of Tampa, Florida, the ALOFT field campaign logged approximately 60 hours of flight time across Central America and the Caribbean. The team used NASA Armstrong’s ER-2 aircraft to fly near thunderclouds as tall as 18 kilometers (10 miles) in altitude in order to measure gamma-ray glows and flashes produced by the electric fields of thunderclouds. ALOFT is short for Airborne Lightning Observatory for Fly’s Eye GLM Simulator and Terrestrial gamma-ray flashes. The campaign included researchers and flight crews from the University of Bergen, NRL, NASA’s Armstrong Flight Research Center, NASA’s Marshall Space Flight Center, and NASA’s Goddard Space Flight Center.
NASA’s ER-2 Aircraft Flies High to Investigate Lightning
In July 2023, NASA’s ER-2 aircraft has been flying close to thunderclouds to investigate lightning and its connection to the vast energy fields in our atmosphere. As the highest-flying plane of NASA’s Airborne Science Program, the ER-2 is giving researchers a new angle on storm clouds.
NASA Pilots Get Dunked
What’s it like to escape from an aircraft underwater? NASA research pilots Wayne Ringelberg, and Scott Howe recently found out when they completed pilot dunker training at the FAA (Federal Aviation Administration) Mike Monroney Aeronautical Center Civil Aerospace Medical Institute in Oklahoma. This training certifies the pilots to fly helicopters over bodies of water for upcoming automated systems flight testing for NASA’s Advanced Air Mobility research with Sikorsky and DARPA (Defense Advanced Research Project Agency).
Elation Through Filtration: An Oceanographer’s Sensations at Sea
Being a biological oceanographer on a physical oceanographic voyage has highlighted a key distinction between the two disciplines. Physical oceanographers rely on sensing – deploying instrumentation that measures properties of the water: temperature, velocity, oxygen, etc. Those data are sent back to laptops allowing for near instantaneous analysis. The day-to-day work of biological oceanography, on the other hand, may be a science best described by filtering – a task that is intertwined with most measurements in our field. We collect water and remove the particles or organisms we want to study. The finest filter might have holes that let only the tiniest particles through, while the largest filter could be something like a large net, where even fish can slip through its mesh.
In Dust and Clouds Over Africa, Scientists Find Clues to How Hurricanes Form
When the dust that wafts off the Sahel and Sahara regions of Africa mixes with tropical clouds, it creates what’s known as a rainy “disturbance” in the eastern Atlantic. These disturbances are hurricanes in their youngest form, and as they travel across the ocean, they can either dissipate or grow into powerful storms.
To study these infant storms, a group of NASA scientists in September 2022 spent a month flying off the northwestern coast of Africa aboard NASA’s DC-8 research plane. Each day, the team took off from Cabo Verde, an island nation off the west coast of Africa, logging roughly 100 hours altogether. The mission, known as the Convective Processes Experiment – Cabo Verde (CPEX-CV) released its data publicly on April 1.
A look at NASA’s new mission to explore the Earth’s oceans
Scientists at NASA are on a mission to study the surface of the Earth's oceans to observe how eddies, whirlpools and currents interact with the atmosphere and shape the Earth’s climate. NBC’s Jacob Soboroff reports for TODAY.
On the Edge: NASA’s Last S-MODE Mission Studies the Ocean’s Surface
NASA has taken to the seas and skies to study the unique environment at the ocean’s surface, where marine ecosystems intersect with our planet's complex atmosphere. On April 7, 2023, scientists participating in the Sub-Mesoscale Ocean Dynamics Experiment (S-MODE) embarked on the RV Sally Ride from San Diego on the last of three field expeditions to understand the ocean’s role in the Earth’s changing climate. They will be at sea for about a month until returning to San Diego on May 4, and they will operate for most of that period in tandem with an accompanying airborne campaign.

Scientists are flying into snowstorms to explore winter weather mysteries
High up in some ice-filled clouds, sitting inside an airplane loaded with science instruments, Christian Nairy looked at pictures flashing on his computer screen. This high-altitude slideshow is displaying real-time images of cloud particles being sampled by a device out on the plane's wing — and some of the ice crystals looked like perfect little snowflakes.

A Nervous Flier’s Guide to Riding the Snowy Skies
I grew up flying in planes. I’m comfortable in them. But there’s one part of flying I’ve never gotten used to: turbulence. It’s common on commercial flights, so over the years I’ve learned a few tips and tricks on how to stay calm when my mind seems to take off at a sprint.
How a Cold War spy plane went from watching the Soviets to watching the weather for NASA
Located just north of Atlanta, Georgia, Dobbins Air Reserve Base is usually home to C-130 transport planes. But for the next few weeks, the base will host an unusual guest: a white-painted jet that can fly for more than half a day at the edge of space.
NASA’s C-20A deploys to Hawaii Following Volcanic Eruption
Following the eruption of the world’s largest active volcano, Mauna Loa, NASA Armstrong Flight Research Center deployed its C-20A aircraft to Kona, Hawaii, to gather images and data of the active lava flows for submission to the United States Geological Survey (USGS) by a team of scientists at NASA’s Jet Propulsion Laboratory (JPL).
Cloudy with a Chance for Whirlpools: Ocean Models Guide NASA’s S-MODE Mission
NASA’s S-MODE mission faces quite the challenge: robustly observe, for the first time, ocean features spanning up to about 6.2 miles (10 kilometers) across. Currently, the oceanographic community routinely observes and studies very large ocean features, primarily through space-based instrumentation. These include strong currents such as the Gulf Stream that runs from Florida along the East Coast of the United States all the way to western Europe. Large vortexes are also observed – these being the cyclones and anticyclones you may have seen on your evening weather forecasts.
Where No Map Leads: Reflections from NASA’s S-MODE Mission
It’s like stumbling through a thick forest and breaking out into a glade. A quiet has settled on this piece of sea as the waves calm. You can’t make a good map to get to this place. In the ocean, these glades are always moving, twisting, being born into life by the collision of great currents, then breaking apart, fracturing and sinking beneath the waves. The cold water brought from below by the coastal winds creates a fog that lies heavy on the sea surface, creating this small, calm spot.
Places like this can be found by things with nowhere else to go. Throw something off the side of a boat and it will likely end up somewhere like here. We’re at a convergence zone that attracts floating debris of all sizes. In particular, it attracts minuscule plankton, along with all the things that eat them and all the things that eat those things and so on and so on. All of it dragged hereby the undulating ocean.
Finding Nature at Sea During NASA’s S-MODE Field Campaign
My favorite part of being at sea is the opportunity to see unique parts of the natural world that aren’t accessible from land. My colleagues have done a fantastic job in their blog posts explaining the science that we’ve been conducting during S-MODE, so I want to take this opportunity to describe some of the sights that those of us on the Bold Horizon have been able to enjoy during our field work: birds, mammals, weather, and stars.
A First Cruise Experience with NASA’s S-MODE Field Campaign
I had been patiently waiting and dreaming about this research cruise for months. Yet a few days before traveling from Connecticut to Oregon for ship mobilization, I couldn’t shake a feeling of denial – like I couldn’t believe I was really going to be out in the Pacific Ocean on a research vessel for an entire month.
I am participating in NASA’s Sub-Mesoscale Ocean Dynamics Experiment (S-MODE) as part of the science party aboard the research vessel Bold Horizon. The focus of this experiment is to sample ocean fronts that are a few miles in size to study their dynamics and effects on vertical transport. The ocean fronts are sampled using aircraft, ship surveying, and autonomous platforms with names such as wave gliders, sea gliders, Saildrones, floats, and drifters. So being aboard the ship is just one piece of this complex research experiment.
Life at Sea: A “First-Timer” Chronicles NASA’s S-MODE Field Campaign
Going to sea for the first time as part of NASA’s S-MODE mission has been an experience like no other. You establish a new normal on the boat and quickly fall into new routines. Perceptions of time even change! I joked with some people on the boat that time is but a label on our samples. Perhaps that’s a bit dramatic, but normal perceptions of time do not apply at sea –especially if you start your day at 2 pm and finish at 2 am.
Student of the Sea: Learning the Ropes Aboard NASA’s S-MODE Mission
NASA’s S-MODE mission was designed to measure and understand the complex oceanic features classified as “submesoscale,” i.e., features spanning up to 6.2 miles (10 kilometers) across. Such fine filaments and sharp density fronts in the ocean are responsible for fast and unpredictable changes in velocity, temperature, salinity, and even among small organisms called plankton in the surface layer of the ocean. A myriad of autonomous instruments, airborne sensors, and a fully equipped ship are part of the robust methods of measuring submesoscale dynamics in the California Current region.
NASA’s S-MODE Field Campaign Deploys to the Pacific Ocean
When the research vessel Bold Horizon sailed from Newport, Oregon, in early October, it joined a small armada of planes, drones, and other high-tech craft chasing the ocean’s shapeshifting physics. NASA’s Sub-Mesoscale Ocean Dynamics Experiment (S-MODE) is converging on a patch of sea 110 nautical miles off the coast of San Francisco. Over the course of 28 days, the team will deploy a new generation of tools to observe whirlpools, currents, and other dynamics at the air-sea boundary. The goal: to understand how these dynamics drive the give-and-take of nutrients and energy between the ocean and atmosphere and, ultimately, help shape Earth’s climate.
Alaska’s Newest Lakes Are Belching Methane
“This lake wasn’t here 50 years ago.” Katey Walter Anthony, an ecologist at the University of Alaska-Fairbanks, dips her paddle into the water as her kayak glides across the lake. “Years ago, the ground was about three meters taller and it was a spruce forest,” she says. Big Trail Lake is a thermokarst lake, which means it formed due to permafrost thaw. Permafrost is ground that stays frozen year round; the permafrost in interior Alaska also has massive wedges of actual ice locked within the frozen ground. When that ice melts, the ground surface collapses and forms a sinkhole that can fill with water. Thus, a thermokarst lake is born.

Walking Back in Time to Learn About the Future of Permafrost
There’s a freezer door in the mountainside outside of Fairbanks, Alaska. Tom Douglas opens it and we step inside, breathing in cold air and musky dust as we start to walk back through time. This isn’t fantasy. It’s the Permafrost Tunnel run by the U.S. Army’s Cold Regions Research and Engineering Laboratory in Alaska, where Douglas is a Senior Scientist. Recently, Douglas led a group of scientists and pilots with NASA’s Arctic Boreal Vulnerability Experiment (ABoVE) on a tour through the Tunnel to learn about permafrost. Permafrost is any soil, ice, or organic matter like plant material or bone that has stayed frozen year-round for at least two years. The tunnel was initially excavated in the 1960s and has been expanded since 2011. Now, the Permafrost Tunnel has almost 500 meters of excavation. “There’s just nowhere else on Earth that has this type of access to permafrost,” said Douglas.
Measuring Methane in the Everglades
The field campaign—called Blue Carbon Prototype Products for Mangrove Methane and Carbon Dioxide Fluxes (BLUEFLUX)—is designed to measure the methane and carbon dioxide changes at key wetlands around the Caribbean. Field teams took samples from the ground, while NASA’s Carbon Airborne Flux Experiment (CARAFE) aircraft measured methane emissions from the same locations from above. The broader goal of the campaign is to link ground and aerial data with satellite observations using machine learning and artificial intelligence algorithms in order to produce a daily methane flux dataset for the Caribbean region.
SARP Ozone Sondes Coincide with SAGE III/ISS Measurements
A NASA student research program recently took to the stratosphere to make ozone measurements that coincided with events from the Stratospheric Aerosol and Gas Experiment (SAGE) III on the International Space Station (ISS), an instrument developed at NASA’s Langley Research Center in Hampton, Virginia.
