Preparations for Next Moonwalk Simulations Underway (and Underwater)
Ocean currents swirl around North America (center left) and Greenland (upper right) in this data visualization created using NASA’s ECCO model. Advanced computing is helping oceanographers decipher hot spots of phytoplankton growth.NASA’s Scientific Visualization Studio As Greenland’s ice retreats, it’s fueling tiny ocean organisms. To test why, scientists turned to a computer model out of JPL and MIT that’s been called a laboratory in itself.
Runoff from Greenland’s ice sheet is kicking nutrients up from the ocean depths and boosting phytoplankton growth, a new NASA-supported study has found. Reporting in Nature Communications: Earth & Environment, the scientists used state-of-the art-computing to simulate marine life and physics colliding in one turbulent fjord. Oceanographers are keen to understand what drives the tiny plantlike organisms, which take up carbon dioxide and power the world’s fisheries.
Greenland’s mile-thick ice sheet is shedding some 293 billion tons (266 billion metric tons) of ice per year. During peak summer melt, more than 300,000 gallons (1,200 cubic meters) of fresh water drain into the sea every second from beneath Jakobshavn Glacier, also known as Sermeq Kujalleq,the most active glacier on the ice sheet. The waters meet and tumble hundreds of feet below the surface.
Teal-colored phytoplankton bloom off the Greenland coast in this satellite image captured in June 2024 by NASA’s PACE (Plankton, Aerosol, Cloud, ocean Ecosystem) mission.NASA The meltwater plume is fresh and more buoyant than the surrounding saltwater. As it rises, scientists have hypothesized, it may be delivering nutrients like iron and nitrate — a key ingredient in fertilizer — to phytoplankton floating at the surface.
Researchers track these microscopic organisms because, though smaller by far than a pinhead, they’re titans of the ocean food web. Inhabiting every ocean from the tropics to the polar regions, they nourish krill and other grazers that, in turn, support larger animals, including fish and whales.
Previous work using NASA satellite data found that the rate of phytoplankton growth in Arctic waters surged 57% between 1998 and 2018 alone. An infusion of nitrate from the depths would be especially pivotal to Greenland’s phytoplankton in summer, after most nutrients been consumed by prior spring blooms. But the hypothesis has been hard to test along the coast, where the remote terrain and icebergs as big as city blocks complicate long-term observations.
“We were faced with this classic problem of trying to understand a system that is so remote and buried beneath ice,” said Dustin Carroll, an oceanographer at San José State University who is also affiliated with NASA’s Jet Propulsion Laboratory in Southern California. “We needed a gem of a computer model to help.”
Sea of Data
To re-create what was happening in the waters around Greenland’s most active glacier, the team harnessed a model of the ocean developed at JPL and the Massachusetts Institute of Technology in Cambridge. The model ingests nearly all available ocean measurements collected by sea- and satellite-based instruments over the past three decades. That amounts to billions of data points, from water temperature and salinity to pressure at the seafloor. The model is called Estimating the Circulation and Climate of the Ocean-Darwin (ECCO-Darwin for short).
Simulating “biology, chemistry, and physics coming together” in even one pocket along Greenland’s 27,000 miles (43,000 kilometers) of coastline is a massive math problem, noted lead author Michael Wood, a computational oceanographer at San José State University. To break it down, he said the team built a “model within a model within a model” to zoom in on the details of the fjord at the foot of the glacier.
Using supercomputers at NASA’s Ames Research Center in Silicon Valley, they calculated that deepwater nutrients buoyed upward by glacial runoff would be sufficient to boost summertime phytoplankton growth by 15 to 40% in the study area.
More Changes in Store
Could increased phytoplankton be a boon for Greenland’s marine animals and fisheries? Carroll said that untangling impacts to the ecosystem will take time. Melt on the Greenland ice sheet is projected to accelerate in coming decades, affecting everything from sea level and land vegetation to the saltiness of coastal waters.
“We reconstructed what’s happening in one key system, but there’s more than 250 such glaciers around Greenland,” Carroll said. He noted that the team plans to extend their simulations to the whole Greenland coast and beyond.
Some changes appear to be impacting the carbon cycle both positively and negatively: The team calculated how runoff from the glacier alters the temperature and chemistry of seawater in the fjord, making it less able to dissolve carbon dioxide. That loss is canceled out, however, by the bigger blooms of phytoplankton taking up more carbon dioxide from the air as they photosynthesize.
Wood added: “We didn’t build these tools for one specific application. Our approach is applicable to any region, from the Texas Gulf to Alaska. Like a Swiss Army knife, we can apply it to lots of different scenarios.”

Captured at a location called “Falbreen,” this enhanced-color mosaic features decep-tively blue skies and the 43rd rock abrasion (the white patch at center-left) of the NASA Perseverance rover’s mission at Mars. The 96 images stitched together to create this 360-degree view were acquired May 26, 2025.NASA/JPL-Caltech/ASU/MSSS In this natural-color version of the “Falbreen” panorama, colors have not been enhanced and the sky appears more reddish. Visible still is Perseverance’s 43rd rock abrasion (the white patch at center-left). The 96 images stitched together to create this 360-degree view were acquired May 26, 2025.NASA/JPL-Caltech/ASU/MSSS ‘Float rocks,’ sand ripples, and vast distances are among the sights to see in the latest high-resolution panorama by the six-wheeled scientist.
The imaging team of NASA’s Perseverance Mars rover took advantage of clear skies on the Red Planet to capture one of the sharpest panoramas of its mission so far. Visible in the mosaic, which was stitched together from 96 images taken at a location the science team calls “Falbreen,” are a rock that appears to lie on top of a sand ripple, a boundary line between two geologic units, and hills as distant as 40 miles (65 kilometers) away. The enhanced-color version shows the Martian sky to be remarkably clear and deceptively blue, while in the natural-color version, it’s reddish.
“Our bold push for human space exploration will send astronauts back to the Moon,” said Sean Duffy, acting NASA administrator. “Stunning vistas like that of Falbreen, captured by our Perseverance rover, are just a glimpse of what we’ll soon witness with our own eyes. NASA’s groundbreaking missions, starting with Artemis, will propel our unstoppable journey to take human space exploration to the Martian surface. NASA is continuing to get bolder and stronger.”
The rover’s Mastcam-Z instrument captured the images on May 26, 2025, the 1,516th Martian day, or sol, of Perseverance’s mission, which began in February 2021 on the floor of Jezero Crater. Perseverance reached the top of the crater rim late last year.
“The relatively dust-free skies provide a clear view of the surrounding terrain,” said Jim Bell, Mastcam-Z’s principal investigator at Arizona State University in Tempe. “And in this particular mosaic, we have enhanced the color contrast, which accentuates the differences in the terrain and sky.”
Buoyant Boulder
One detail that caught the science team’s attention is a large rock that appears to sit atop a dark, crescent-shaped sand ripple to the right of the mosaic’s center, about 14 feet (4.4 meters) from the rover. Geologists call this type of rock a “float rock” because it was more than likely formed someplace else and transported to its current location. Whether this one arrived by a landslide, water, or wind is unknown, but the science team suspects it got here before the sand ripple formed.
The bright white circle just left of center and near the bottom of the image is an abrasion patch. This is the 43rd rock Perseverance has abraded since it landed on Mars. Two inches (5 centimeters) wide, the shallow patch is made with the rover’s drill and enables the science team to see what’s beneath the weathered, dusty surface of a rock before deciding to drill a core sample that would be stored in one of the mission’s titanium sample tubes.
The rover made this abrasion on May 22 and performed proximity science (a detailed analysis of Martian rocks and soil) with its arm-mounted instruments two days later. The science team wanted to learn about Falbreen because it’s situated within what may be some of the oldest terrain Perseverance has ever explored — perhaps even older than Jezero Crater.
Tracks from the rover’s journey to the location can be seen toward the mosaic’s right edge. About 300 feet (90 meters) away, they veer to the left, disappearing from sight at a previous geologic stop the science team calls “Kenmore.”
A little more than halfway up the mosaic, sweeping from one edge to the other, is the transition from lighter-toned to darker-toned rocks. This is the boundary line, or contact, between two geologic units. The flat, lighter-colored rocks nearer to the rover are rich in the mineral olivine, while the darker rocks farther away are believed to be much older clay-bearing rocks.

NASA Astronaut Barry “Butch” WilmoreNASA/Aubrey Gemignani
After 25 years at NASA, flying in four different spacecraft, accumulating 464 days in space, astronaut and test pilot Butch Wilmore has retired from NASA.
The Tennessee native earned a bachelor’s and a master’s degree in electrical engineering from Tennessee Technological University and a master’s degree in aviation systems from the University of Tennessee.
Wilmoreis a decorated U.S. Navy captain who has flown numerous tactical aircraft operationally while deploying aboard four aircraft carriers during peacetime and combat operations. A graduate of the U.S. Naval Test Pilot School, he went on to serve as a test pilot before NASA selected him to become an astronaut in 2000.
“Butch’s commitment to NASA’s mission and dedication to human space exploration is truly exemplary,” said Steve Koerner, acting director of NASA’s Johnson Space Center in Houston. “His lasting legacy of fortitude will continue to impact and inspire the Johnson workforce, future explorers, and the nation for generations. On behalf of NASA’s Johnson Space Center, we thank Butch for his service.”
During his time at NASA, Wilmore completed three missions launching aboard the space shuttle Atlantis, Roscosmos Soyuz, and Boeing Starliner to the International Space Station. Wilmore also returned to Earth aboard a SpaceX Dragon spacecraft. Additionally, he conducted five spacewalks, totaling 32 hours outside the orbital laboratory.
“Throughout his career, Butch has exemplified the technical excellence of what is required of an astronaut. His mastery of complex systems, coupled with his adaptability and steadfast commitment to NASA’s mission, has inspired us all,” said Joe Acaba, chief of the Astronaut Office at NASA Johnson. “As he steps into this new chapter, that same dedication will no doubt continue to show in whatever he decides to do next.”
Most recently, Wilmore launched aboard Boeing’s Starliner spacecraft on June 5, 2024, for its first crewed flight test mission, arriving at the space station the following day. While aboard the station, Wilmore completed numerous tasks, including a spacewalk to help remove a radio frequency group antenna assembly from the station’s truss and collected samples and surface material for analysis from the Destiny laboratory and the Quest airlock.
“From my earliest days, I have been captivated by the marvels of creation, looking upward with an insatiable curiosity. This curiosity propelled me into the skies, and eventually to space, where the magnificence of the cosmos mirrored the glory of its creator in ways words can scarcely convey,” said Wilmore. “Even as I ventured beyond Earth’s limits, I remained attuned to the beauty and significance of the world below, recognizing the same intricate design evident among the stars is also woven into the fabric of life at home.”
