Inside a laboratory in the Space Systems Processing Facility at NASA’s Kennedy Space Center in Florida, a payload implementation team member harvests ‘Outredgeous’ romaine lettuce growing in the Advanced Plant Habitat ground unit on Thursday, April 24, 2025. The harvest is part of the ground control work supporting Plant Habitat-07, which launched to the International Space Station aboard NASA’s SpaceX 31st commercial resupply services mission.
The experiment focuses on studying how optimal and suboptimal moisture conditions affect plant growth, nutrient content, and the plant microbiome in microgravity. Research like this continues NASA’s efforts to grow food that is not only safe but also nutritious for astronauts living and working in the harsh environment of space.
The ‘Outredgeous’ romaine lettuce variety was first grown aboard the space station in 2014, and Plant Habitat-07 builds on that legacy, using the station’s Advanced Plant Habitat to expand understanding of how plants adapt to spaceflight conditions. Findings from this work will support future long-duration missions to the Moon, Mars, and beyond, and could also lead to agricultural advances here on Earth.

Having just finished a pre-flight mission briefing with his team, the only thing on his mind is heading to the aircraft hangar and getting a plane in the air.
As he eases a small white-and-blue propeller aircraft down the hangar’s ramp and onto the runway, he hears five essential words crackle through his headset: “NASA 606, cleared for takeoff.”
This is a typical morning for Johnson, a research pilot and aviation safety officer at NASA’s Glenn Research Center in Cleveland. Johnson flies NASA planes to support important scientific research and testing, working with researchers to plan and carry out flights that will get them the data they need while ensuring safety.
Johnson hasn’t always flown in NASA planes. He comes to the agency from the U.S. Air Force, where he flew missions all over the world in C-17 cargo aircraft, piloted unmanned reconnaissance operations out of California, and trained young aviators in Oklahoma on the fundamentals of flying combat missions.
Jeremy Johnson stands beside a C-17 aircraft before a night training flight in Altus, Oklahoma, in 2020. Before supporting vital flight research at NASA through a SkillBridge fellowship, which gives transitioning service members the opportunity to gain civilian work experience, Johnson served in the U.S. Air Force and flew C-17 airlift missions all over the world.Credit: Courtesy of Jeremy Johnson He’s at Glenn for a four-month Department of Defense SkillBridge fellowship. The program gives transitioning service members an opportunity to gain civilian work experience through training, apprenticeships, or internships during their last 180 days of service before separating from the military.
“I think SkillBridge has been an amazing tool to help me transition into what it’s like working somewhere that isn’t the military,” Johnson said. “In the Air Force, flying the mission was the mission. At NASA Glenn, the science—the research—is the mission.”
By flying aircraft outfitted with research hardware or carrying test equipment, Johnson has contributed to two vital projects at NASA so far. One is focused on testing how well laser systems can transmit signals for communication and navigation. The other, part of NASA’s research under Air Mobility Pathfinders, explores how 5G telecommunications infrastructure can help electric air taxis of the future be safely incorporated into the national airspace. This work, and the data that scientists can collect through flights, supports NASA’s research to advance technology and innovate for the benefit of all.

You remember, this is a small little piece of something that is maybe going to change the frontier of science, the frontier of discovery.”
Johnson has always had a passion for aviation. In college, he worked as a valet to pay for flying lessons. To hone his skills before Air Force training, one summer he flew across the country in a Cessna with his aunt, a commercial pilot. They flew down the Hudson River as they watched the skyscrapers of New York City whizz by and later to Kitty Hawk, North Carolina, where the Wright brothers made their historic first flight. Johnson even flew skydivers part-time while he was stationed in California.

Despite his successes, Johnson’s journey to becoming a pilot wasn’t always smooth. He recalls that as he was about to land after his first solo flight, violent crosswinds blew his plane off the runway and sent him bouncing into the grass. Though he eventually got back behind the stick for another flight, he said that in that moment he wondered whether he had the strength and skills to overcome his self-doubt.
“I don’t know anyone who flies for a living that had a completely easy path into it,” Johnson said. “To people who are thinking about getting into flying, just forge forward with it. Make people close doors on you, don’t close them on yourself, when it comes to flying or whatever you see yourself doing in the future. I just kept knocking on the door until there was a crack in it.”

Preparations for Next Moonwalk Simulations Underway (and Underwater)
NASA’s AVIRIS-3 airborne imaging spectrometer was used to map a wildfire near Cas-tleberry, Alabama, on March 19. Within minutes, the image was transmitted to firefighters on the ground, who used it to contain the blaze. NASA/JPL-Caltech, NASA Earth Observatory The map visualizes three wavelengths of infrared light, which are invisible to the human eye. Orange and red areas show cooler-burning areas, while yellow indicates the most intense flames. Burned areas show up as dark red or brown.NASA/JPL-Caltech, NASA Earth Observatory Data from the AVIRIS-3 sensor was recently used to create detailed fire maps in minutes, enabling firefighters in Alabama to limit the spread of wildfires and save buildings.
A NASA sensor recently brought a new approach to battling wildfire, providing real-time data that helped firefighters in the field contain a blaze in Alabama. Called AVIRIS-3, which is short for Airborne Visible Infrared Imaging Spectrometer 3, the instrument detected a 120-acre fire on March 19 that had not yet been reported to officials.
As AVIRIS-3 flew aboard a King Air B200 research plane over the fire about 3 miles (5 kilometers) east of Castleberry, Alabama, a scientist on the plane analyzed the data in real time and identified where the blaze was burning most intensely. The information was then sent via satellite internet to fire officials and researchers on the ground, who distributed images showing the fire’s perimeter to firefighters’ phones in the field.
All told, the process from detection during the flyover to alert on handheld devices took a few minutes. In addition to pinpointing the location and extent of the fire, the data showed firefighters its perimeter, helping them gauge whether it was likely to spread and decide where to add personnel and equipment.
As firefighters worked to prevent a wildfire near Perdido, Alabama, from reaching nearby buildings, they saw in an infrared fire map from NASA’s AVIRIS-3 sensor that showed the fire’s hot spot was inside its perimeter. With that intelligence, they shifted some resources to fires in nearby Mount Vernon.NASA/JPL-Caltech, NASA Earth Observatory “This is very agile science,” said Robert Green, the AVIRIS program’s principal investigator and a senior research scientist at NASA’s Jet Propulsion Laboratory in Southern California, noting AVIRIS-3 mapped the burn scar left near JPL by the Eaton Fire in January.
Observing the ground from about 9,000 feet (3,000 meters) in altitude, AVIRIS-3 flew aboard several test flights over Alabama, Mississippi, Florida, and Texas for a NASA 2025 FireSense Airborne Campaign. Researchers flew in the second half of March to prepare for prescribed burn experiments that took place in the Geneva State Forest in Alabama on March 28 and at Fort Stewart-Hunter Army Airfield in Georgia from April 14 to 20. During the March span, the AVIRIS-3 team mapped at least 13 wildfires and prescribed burns, as well as dozens of small hot spots (places where heat is especially intense) — all in real time.
At one of the Mount Vernon, Alabama, fires, firefighters used AVIRIS-3 maps to determine where to establish fire breaks beyond the northwestern end of the fire. They ultimately cut the blaze off within about 100 feet (30 meters) of four buildings.NASA/JPL-Caltech, NASA Earth Observatory Data from imaging spectrometers like AVIRIS-3 typically takes days or weeks to be processed into highly detailed, multilayer image products used for research. By simplifying the calibration algorithms, researchers were able to process data on a computer aboard the plane in a fraction of the time it otherwise would have taken. Airborne satellite internet connectivity enabled the images to be distributed almost immediately, while the plane was still in flight, rather than after it landed.
The AVIRIS team generated its first real-time products during a February campaign covering parts of Panama and Costa Rica, and they have continued to improve the process, automating the mapping steps aboard the plane.
‘Fan Favorite’
The AVIRIS-3 sensor belongs to a line of imaging spectrometers built at JPL since 1986. The instruments have been used to study a wide range of phenomena — including fire — by measuring sunlight reflecting from the planet’s surface.
During the March flights, researchers created three types of maps. One, called the Fire Quicklook, combines brightness measurements at three wavelengths of infrared light, which is invisible to the human eye, to identify the relative intensity of burning. Orange and red areas on the Fire Quicklook map show cooler-burning areas, while yellow indicates the most intense flames. Previously burned areas show up as dark red or brown.
Another map type, the Fire 2400 nm Quicklook, looks solely at infrared light at a wavelength of 2,400 nanometers. The images are particularly useful for seeing hot spots and the perimeters of fires, which show brightly against a red background.
A third type of map, called just Quicklook, shows burned areas and smoke.
The Fire 2400 nm Quicklook was the “fan favorite” among the fire crews, said Ethan Barrett, fire analyst for the Forest Protection Division of the Alabama Forestry Commission. Seeing the outline of a wildfire from above helped Alabama Forestry Commission firefighters determine where to send bulldozers to stop the spread.
Additionally, FireSense personnel analyzed the AVIRIS-3 imagery to create digitized perimeters of the fires. This provided firefighters fast, comprehensive intelligence of the situation on the ground.
That’s what happened with the Castleberry Fire. Having a clear picture of where it was burning most intensely enabled firefighters to focus on where they could make a difference — on the northeastern edge.
Then, two days after identifying Castleberry Fire hot spots, the sensor spotted a fire about 4 miles (2.5 kilometers) southwest of Perdido, Alabama. As forestry officials worked to prevent flames from reaching six nearby buildings, they noticed that the fire’s main hot spot was inside the perimeter and contained. With that intelligence, they decided to shift some resources to fires 25 miles (40 kilometers) away near Mount Vernon, Alabama.
To combat one of the Mount Vernon fires, crews used AVIRIS-3 maps to determine where to establish fire breaks beyond the northwestern end of the fire. They ultimately cut the blaze off within about 100 feet (30 meters) of four buildings.
“Fire moves a lot faster than a bulldozer, so we have to try to get around it before it overtakes us. These maps show us the hot spots,” Barrett said. “When I get out of the truck, I can say, ‘OK, here’s the perimeter.’ That puts me light-years ahead.”
AVIRIS and the Firesense Airborne Campaign are part of NASA’s work to leverage its expertise to combat wildfires using solutions including airborne technologies. The agency also recently demonstrated a prototype from its Advanced Capabilities for Emergency Response Operations project that will provide reliable airspace management for drones and other aircraft operating in the air above wildfires.

5 Min Read Planetary Alignment Provides NASA Rare Opportunity to Study Uranus
Artist's illustration showing a distant star going out of sight as it is eclipsed by Uranus – an event known as a planetary stellar occultation. Credits: NASA/Advanced Concepts Laboratory When a planet’s orbit brings it between Earth and a distant star, it’s more than just a cosmic game of hide and seek. It’s an opportunity for NASA to improve its understanding of that planet’s atmosphere and rings. Planetary scientists call it a stellar occultation and that’s exactly what happened with Uranus on April 7.
Observing the alignment allows NASA scientists to measure the temperatures and composition of Uranus’ stratosphere – the middle layer of a planet’s atmosphere – and determine how it has changed over the last 30 years since Uranus’ last significant occultation.

This rendering demonstrates what is happening during a stellar occultation and illustrates an example of the light curve data graph recorded by scientists that enables them to gather atmospheric measurements, like temperature and pressure, from Uranus as the amount of starlight changes when the planet eclipses the star.NASA/Advanced Concepts Laboratory “Uranus passed in front of a star that is about 400 light years from Earth,” said William Saunders, planetary scientist at NASA’s Langley Research Center in Hampton, Virginia, and science principal investigator and analysis lead, for what NASA’s team calls the Uranus Stellar Occultation Campaign 2025. “As Uranus began to occult the star, the planet’s atmosphere refracted the starlight, causing the star to appear to gradually dim before being blocked completely. The reverse happened at the end of the occultation, making what we call a light curve. By observing the occultation from many large telescopes, we are able to measure the light curve and determine Uranus’ atmospheric properties at many altitude layers.”

This data mainly consists of temperature, density, and pressure of the stratosphere. Analyzing the data will help researchers understand how the middle atmosphere of Uranus works and could help enable future Uranus exploration efforts.
To observe the rare event, which lasted about an hour and was only visible from Western North America, planetary scientists at NASA Langley led an international team of over 30 astronomers using 18 professional observatories.
Kunio Sayanagi, NASA’s principal investigator for the Uranus Stellar Occultation Campaign 2025, meeting virtually with partners and observing data from the Flight Mission Support Center at NASA’s Langley Research Center in Hampton, Virginia during Uranus’ stellar occultation event on April 7, 2025.NASA/Dave MacDonnell “This was the first time we have collaborated on this scale for an occultation,” said Saunders. “I am extremely grateful to each member of the team and each observatory for taking part in this extraordinary event. NASA will use the observations of Uranus to determine how energy moves around the atmosphere and what causes the upper layers to be inexplicably hot. Others will use the data to measure Uranus’ rings, its atmospheric turbulence, and its precise orbit around the Sun.”
Knowing the location and orbit of Uranus is not as simple as it sounds. In 1986, NASA’s Voyager 2 spacecraft became the first and only spacecraft to fly past the planet – 10 years before the last bright stellar occultation occured in 1996. And, Uranus’ exact position in space is only accurate to within about 100 miles, which makes analyzing this new atmospheric data crucial to future NASA exploration of the ice giant.
These investigations were possible because the large number of partners provided many unique views of the stellar occultation from many different instruments.
NASA planetary scientist William Saunders and Texas A&M University research assistant Erika Cook in the control room of the McDonald Observatory’s Otto Struve Telescope in Jeff Davis County, Texas, during the Uranus stellar occultation on April 7, 2025.Joshua Santana Emma Dahl, a postdoctoral scholar at Caltech in Pasadena, California, assisted in gathering observations from NASA’s Infrared Telescope Facility (IRTF) on the summit of Mauna Kea in Hawaii – an observatory first built to support NASA’s Voyager missions.
“As scientists, we do our best work when we collaborate. This was a team effort between NASA scientists, academic researchers, and amateur astronomers,” said Dahl. “The atmospheres of the gas and ice giant planets [Jupiter, Saturn, Uranus, and Neptune] are exceptional atmospheric laboratories because they don’t have solid surfaces. This allows us to study cloud formation, storms, and wind patterns without the extra variables and effects a surface produces, which can complicate simulations very quickly.”
On November 12, 2024, NASA Langley researchers and collaborators were able to do a test run to prepare for the April occultation. Langley coordinated two telescopes in Japan and one in Thailand to observe a dimmer Uranus stellar occultation only visible from Asia. As a result, these observers learned how to calibrate their instruments to observe stellar occultations, and NASA was able to test its theory that multiple observatories working together could capture Uranus’ big event in April.
Researchers from the Paris Observatory and Space Science Institute, in contact with NASA, also coordinated observations of the November 2024 occultation from two telescopes in India. These observations of Uranus and its rings allowed the researchers, who were also members of the April 7 occultation team, to improve the predictions about the timing on April 7 down to the second and also improved modeling to update Uranus’ expected location during the occultation by 125 miles.
This image of Uranus from NIRCam (Near-Infrared Camera) on NASA’s James Webb Space Telescope exquisitely captures Uranus’s seasonal north polar cap and dim inner and outer rings. This Webb image also shows 9 of the planet’s 27 moons – clockwise starting at 2 o’clock, they are: Rosalind, Puck, Belinda, Desdemona, Cressida, Bianca, Portia, Juliet, and Perdita.NASA, ESA, CSA, STScI Uranus is almost 2 billion miles away from Earth and has an atmosphere composed of primarily hydrogen and helium. It does not have a solid surface, but rather a soft surface made of water, ammonia, and methane. It’s called an ice giant because its interior contains an abundance of these swirling fluids that have relatively low freezing points. And, while Saturn is the most well-known planet for having rings, Uranus has 13 known rings composed of ice and dust.
Over the next six years, Uranus will occult several dimmer stars. NASA hopes to gather airborne and possibly space-based measurements of the next bright Uranus occultation in 2031, which will be of an even brighter star than the one observed in April.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
A researcher inspects the interior of a male American horseshoe crab at NASA’s Kennedy Space Center in Florida. Known scientifically as Limulus polyphemus, the American horseshoe crab is vital to researchers’ understanding of the overall health of NASA Kennedy’s ecosystem.NASA They’re known as “living fossils”.
For over 450 million years, horseshoe crabs have been an ecologically vital part of our planet. They’re one of the few surviving species on Earth dating back to the dinosaurs.
At NASA’s Kennedy Space Center in Florida, the American horseshoe crab (Limulus polyphemus) is one of more than 1,500 types of animals and plants you can find living on its over 144,000 acres, the majority of which is managed by the U.S. Fish and Wildlife Service and National Park Service. Sharing a boundary with the Merritt Island National Wildlife Refuge and Canaveral National Seashore, NASA Kennedy is one of the most biologically diverse places in the United States.
The center’s land, water, and air species live alongside the symbols of America’s space program: the vital facilities and infrastructure that support the many launches at NASA Kennedy and Cape Canaveral Space Force Station as well as the rockets enabling humanity’s exploration of the cosmos.
Researchers measure the shell of a male and female American horseshoe crab at NASA’s Kennedy Space Center in Florida. Known scientifically as Limulus polyphemus, the American horseshoe crab is vital to researchers’ understanding of the overall health of NASA Kennedy’s ecosystem. Preserving NASA Kennedy’s wildlife while also fulfilling the agency’s mission requires a balanced approach. The American horseshoe crab exemplifies that balance.
Horseshoe crabs are keystone species in coastal and estuary systems like the ones surrounding Earth’s premier spaceport. By themselves, these resilient arthropods are a strong indicator of how an ecosystem is doing to support the migratory birds, sea turtles, alligators and other wildlife who rely on it for their survival.
“The presence and abundance of horseshoe crabs influence the structure and functioning of the entire ecosystem,” said James T. Brooks, an environmental protection specialist at NASA Kennedy. “Their eggs provide a vital food source for many shorebirds in coastal habitats, and their feeding activities help shape the composition of plants and animals that live at the bottom of the ocean or in rivers and lakes. Changes in horseshoe crab populations can signal broader ecological issues, such as pollution or habitat loss.”
As featured recently on NASA+, biologists survey NASA Kennedy’s beaches regularly for horseshoe crabs, counting each one they spot and tagging them with devices that lets researchers study their migration patterns and survival rates. The devices also track the crabs’ spawning activity, habitat health, and population trends, especially during peak breeding seasons in spring and summer.
All this data helps in assessing the overall health of NASA Kennedy’s ecosystem, but horseshoe crabs also play a vital role in humanity’s health. Their blue, copper-based blood contains a substance called Limulus Amebocyte Lysate, critical for detecting bacterial contamination in medical equipment, pharmaceuticals, and vaccines.
Their unique value in ensuring biomedical safety underscores why NASA Kennedy emphasizes ecological monitoring in addition to its roles in the global space economy, national defense, and space exploration.
A male and female American horseshoe crab meet during mating season at NASA’s Kennedy Space Center in Florida. Known scientifically as Limulus polyphemus, the American horseshoe crab is vital to researchers’ understanding of the overall health of NASA Kennedy’s ecosystem. NASA At NASA Kennedy, horseshoe crabs are protected and monitored through habitat restoration projects like rebuilding shorelines eroded by storms and minimizing human impact on nesting sites. These initiatives ensure that the spaceport’s operations coexist harmoniously with nature and deepen our understanding of Earth’s interconnected ecosystems.
On this Earth Day, NASA Kennedy celebrates the important role these ancient mariners play as we launch humanity’s future.
