Warm Kelvin waves often precede El Niño events.NASA/JPL-Caltech Sea level data from a satellite launched by NASA and European partners shows that a swell of warm water hundreds of miles wide has arrived in the Pacific Ocean off the coast of South America, a sign that El Niño will likely emerge later in the year. Because water expands as it warms, a rise in elevation of an area of the ocean indicates increasing ocean temperatures. El Niños can cause heavy precipitation in some regions and deficits in others, influencing daily life and commerce around the world. Launched in 2020 by NASA and led by ESA (European Space Agency) for the E.U. Copernicus Programme, the Sentinel-6 Michael Freilich satellite measures and maps water height for the entire ocean every 10 days, down to fractions of an inch. In the case of El Niño, the satellite tracks what are called warm Kelvin waves. These waves typically form after brief periods when winds over the far western equatorial Pacific Ocean shift from prevailing easterlies — moving from east to west — to westerlies. That effect, combined with a general weakening of easterly winds along the equator, causes water in the tropics of the western Pacific to get warmer and sea levels to rise. The wave that forms then propagates east for several weeks, eventually reaching South America and causing water off the coast to heat up and rise. An El Niño develops as multiple Kelvin waves appear over the course of several months, and the warm water accumulates off the shores of Colombia, Ecuador, and Peru. “While this year’s event started a bit later than the big El Niños of 2015 and 1997, it’s beginning to catch up,” said Josh Willis, a sea level researcher at NASA’s Jet Propulsion Laboratory in Southern California and project scientist for Sentinel-6 Michael Freilich. “We’ll see how big it gets.” Measurements from Sentinel-6 Michael Freilich show a small Kelvin wave forming around Micronesia in late January and dissipating by mid-February. A new wave emerged in early March, then moved east over time. By mid-May, the seas around Peru were more than 5.9 inches (15 centimeters) higherthan long-term averages. “NASA’s observation of El Niño uses sea level satellites like Sentinel-6 Michael Freilich to track massive Kelvin waves as they cross the Pacific, capture changes in Earth’s ocean thermodynamics, improve forecasts of weather extremes, and help communities prepare for potential coastal hazards,” said Nadya Vinogradova Shiffer, lead program scientist at NASA Headquarters in Washington. “Stay tuned as more ocean stories continue to unfold.” Tracking El Niño Fishermen in the 1600s coined the name El Niño — Spanish for “the boy,” a reference to the birth of baby Jesus — because it tended to intensify around Christmastime. Warmer waters meant they would catch fewer fish. Warmer sea surface temperatures in the central and eastern Pacific affect atmospheric circulation patterns worldwide by shifting the jet stream, which impacts storm tracks. This can lead to heavy rain and snow in some areas and unusual heat and dryness in others. How far away those impacts appear depends on the strength of the El Niño. In more modest events, like the ones that began in 2018 and 2023, impacts such as drought and flooding were mostly seeb in and around the tropical Pacific. Large El Niños, like the one in 2015-2016, reach much farther, causing drought in Africa and flooding in California. El Niños usually peak between November and January, so it will be several months before the largest impacts become clear. “Every El Niño is different,” said JPL sea level researcher Severine Fournier, deputy project scientist for Sentinel-6 Michael Freilich. “But they almost always make for a hot year and big changes in rainfall in parts of the globe.” Sentinel-6 Michael Freilich is the current official reference satellite for global sea level measurements. Launched in 2020, it is continuing a legacy started in 1992 by the TOPEX/Poseidon satellite. A series of successors have carried the baton since then, and the latest, Sentinel-6B, which launched November 2025, will take over for its predecessor by the end of 2026. More about Sentinel-6 Michael Freilich Sentinel-6 Michael Freilich, named after former NASA Earth Science Division Director Michael Freilich, is one of two satellites that compose the Copernicus Sentinel-6/Jason-CS (Continuity of Service) mission. Sentinel-6/Jason-CS, a part of the European Union’s Earth observation programme called Copernicus, was jointly developed by ESA, the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT), NASA, and the National Oceanic and Atmospheric Administration (NOAA), with funding support from the European Commission and technical support on performance from the French space agency CNES (Centre National d’Études Spatiales). Spacecraft monitoring and control, as well as the processing of all the altimeter science data, is carried out by EUMETSAT on behalf of the European Union’s Copernicus Programme, with the support of all partner agencies. A division of Caltech in Pasadena, JPL contributed three science instruments for each Sentinel-6 satellite: the Advanced Microwave Radiometer, the Global Navigation Satellite System – Radio Occultation, and the Laser Retroreflector Array. NASA also contributed launch services, ground systems supporting operation of the NASA science instruments, the science data processors for two of these instruments, and support for the U.S. members of the international Ocean Surface Topography Science Team.

Students from the University of Virginia pose for a photograph after winning the grand prize during NASA’s 2026 Lunabotics Challenge competition on Thursday, May 21, 2026, inside the Astronauts Memorial Foundation’s Center for Space Education at the Kennedy Space Center Visitor Complex in Florida. NASA/Kim Shiflett Resilient. Efficient. Autonomous. These are qualities NASA demands of its hardware, especially as the agency accelerates plans for a permanent Moon Base. NASA’s 2026 Lunabotics Challenge put those traits on full display, as college student engineers from across the country gathered at the Astronauts Memorial Foundation’s Center for Space Education at the Kennedy Space Center Visitor Complex in Florida to demonstrate robotic technologies and systems engineering expertise that could build and sustain long‑term lunar infrastructure. When the simulated lunar dust settled, the University of Virginia earned the Off World Grand Prize for completing all events and achieving the highest overall score. “The Off World Grand Prize is really about everything,” said Robert Mueller, senior technologist at NASA Kennedy’s Swamp Works, lead judge, and co‑founder of the original Lunabotics robotic mining challenge. “It’s a difficult prize to win, and it’s not obvious, because the team that built the biggest berm didn’t win. But on an actual lunar mission, it’s not just one thing that matters — it’s everything in the system.” Student test bed for lunar construction challenges The agency’s annual Lunabotics Challenge is a two‑semester competition in which higher‑education students design, build, and test prototype lunar construction robots using NASA systems engineering principles. The 2026 competition opened last September, with teams submitting industry plans, engineering reports, and robot specifications. Judges selected 47 teams to advance to a qualifying round at the University of Central Florida’s Exolith Lab in Orlando, where the robots faced their first tests. The goal during the qualifying round was straightforward: excavate and collect simulated lunar soil, transport it across challenging terrain, and construct a berm, or a raised mound of soil used to provide structure, support, or protection. Performance was evaluated across several criteria, and the top 10 teams moved on to the three‑day final round held May 19 to 21 at NASA Kennedy. Judges assessed far more than berm size. Robot weight, communications performance, energy use, and level of autonomy all contributed to scores across four main criteria: a science, technology, engineering, and math (STEM) industry plan; a systems engineering paper; presentations and demonstrations; and robotic construction. The University of Virginia team excelled not only in measurable metrics but also in preparation and resilience. When a wheel detached during their first finals run, the team reconfigured the robot to operate on three wheels and kept digging. “When we saw the wheel break in the arena, we thought that was it,” said Craig Kalkwarf, a fourth‑year aerospace engineering and astronomy major and mechanical lead of the 22‑member team. “But we came so prepared. We had metal wheels ready to swap out. We had a plan. We ultimately got the win, and part of that was planning for anything — and it worked out.” Students from the University of Virginia prepare their prototype lunar robot for its turn during the finals for NASA’s 2026 Lunabotics Challenge competition on Wednesday, May 20, 2026, inside the Astronauts Memorial Foundation’s Center for Space Education at the Kennedy Space Center Visitor Complex in Florida. NASA/Cory S Huston Engineering NASA’s lunar future A key part of the Lunabotics Challenge is students employing NASA’s Systems Engineering Process, a multidisciplinary, mission‑driven approach that integrates hardware, software, people, and procedures to create complex, high‑reliability systems. Competition judges noted that the systems engineering prowess on display this year was among the strongest in the challenge’s 17‑year history. Teams and their robots demonstrated remarkable adaptability in the face of obstacles. Multiple teams overcame wheel issues, robots stuck in rough terrain managed to break free, and one team pressed on after its digger blades damaged their robot, but only after it successfully deposited enough material to create an impressive berm. By the competition’s close, event organizers praised how teams built upon previous robotic designs, as several teams were veterans of the competition, and marveled at the number of fully autonomous robots that competed in the qualifying and final rounds. Last year, there were 12 fully autonomous robots, while this year the number grew to 27. This led to tighter competition, as well as more efficiency during the runs inside the Center for Space Education’s Artemis Arena – the large, engineered test bed filled with lunar soil simulant, designed to mimic the loose, uneven terrain robots will encounter on the Moon. “Teams excavated much more material than we anticipated,” said Rich Johanboeke, project manager for the competition and longtime Lunabotics organizer. “This speaks to how teams have evolved previous design iterations and how much innovation we’re seeing from these students. It’s an exciting time!” The University of Utah team’s prototype lunar robot performs during the finals for NASA’s 2026 Lunabotics Challenge competition on Thursday, May 21, 2026, inside the Astronauts Memorial Foundation’s Center for Space Education at the Kennedy Space Center Visitor Complex in Florida.NASA/Kim Shiflett Challenge designed for the Artemis era Coming just weeks after the success of NASA’s Artemis II mission, Lunabotics highlights some of the next steps toward establishing a sustainable human presence on the Moon. Autonomous robots capable of shaping lunar soil into berms will play a vital role in protecting landing sites, supporting power systems, and forming the building blocks of future lunar outposts. “This might be the first thing NASA does on the Moon Base — robotically building a berm using a local resource, the lunar soil,” Mueller said. “We are watching and learning from these teams in preparation for a real mission launching in a few years, which is IPEx.” Developed at Kennedy’s Swamp Works, IPEx, or Infrastructure Pilot Excavator, is poised to launch to the lunar surface through NASA’s CLPS (Commercial Lunar Payload Services) initiative. Acting as both excavator and hauler, IPEx is designed to dig and transport lunar regolith efficiently, which are critical capabilities for supporting human exploration and making the most of lunar resources. Building engineering pipeline to NASA This year’s Lunabotics Challenge didn’t just celebrate student ingenuity — it helped advance the technologies and engineering approaches that will define the next era of lunar exploration. For students, Lunabotics provides an immersive engineering experience that mirrors industry‑level problem‑solving. For NASA, the competition, like the agency’s other Student Design Challenges, is helping to find novel solutions to technical challenges currently faced by the agency, while also helping recruit the next generation of engineers, technologists, and innovators to NASA. Alumni from the College of DuPage in Glen Ellyn, Illinois, accept the Lunabotics Construction Award on behalf of the team for building the largest berm during NASA’s 2026 Lunabotics Challenge competition on Thursday, May 21, 2026, inside the Astronauts Memorial Foundation’s Center for Space Education at the Kennedy Space Center Visitor Complex in Florida.NASA/Kim Shiflett “I think it’s everyone’s dream to come work at NASA,” said Andrew Ebert, a mechanical engineering student at the College of DuPage in Glen Ellyn, Illinois, whose team took home the prize for building the biggest berm. “It’s always pushing the boundaries of what has ever been done by humans. In my opinion, it’s the coolest thing you can do in engineering.” The creativity, resilience, and technical mastery demonstrated by these teams are directly shaping NASA’s path toward a sustainable Moon Base. When Americans begin lunar construction in a few years, the experience and expertise gained by the young engineers through Lunabotics becomes even more meaningful and potentially impactful for NASA. “These students might be working for NASA by the time we start building on the Moon,” said Mueller.

NASA, ESA, R. Tully (University of Hawaii); Image Processing: G. Kober (NASA/Catholic University of America) This NASA Hubble Space Telescope image features the dwarf irregular galaxy ESO 490-017, roughly 12,000 light-years in diameter and some 23 million light-years away in the constellation Canis Major. The galaxy’s low surface brightness makes it appear as a faint, starry swarm behind brighter foreground stars that are easily recognized by their diffraction spikes. Numerous red, orange, and beige dots are distant galaxies peppering the ****** background, many exhibiting distinct spiral structure. The data in this image of ESO 490-017 was part of a Hubble observing program that looked at the movement of galaxies and galaxy clusters through space. Matter in the universe is distributed unevenly, and the gravitational influence of that matter drives the “cosmic flow” or movement of large-scale structures in the universe. Hubble is uniquely capable of providing distances to nearby galaxies like ESO 490-017 by measuring the luminosities of low-mass red giant stars as “standard candles”. The observing program also provided a legacy archive of the types of stars in local galaxies.

NASA Earth Observatory / Lauren Dauphin In May 2026, the Global Volcanism Program reported nine actively erupting volcanoes in Indonesia—more than any other country at the time. Such activity is typical for the Southeast Asian archipelago, where eruptions have occurred at 55 volcanoes since the 1960s—the highest total for any country. Japan ranks second with eruptions at 40 volcanoes over that time *******, followed by the United States with 39, according to Global Volcanism Program data. Even for such an eruption-prone country, the persistence of activity at Mount Dukono stands out. The remote stratovolcano, located at the northern end of Halmahera Island, has been erupting nearly continuously since 1933, with near-daily rumbles and frequent emissions of ash and volcanic gases. The volcano routinely flings hunks of semi-molten rock, known as volcanic bombs, hundreds of meters from its vent. This sort of activity at Dukono turned deadly on May 8, 2026, when ash and volcanic bombs rained down on a group of hikers. In the days following the tragedy, the mountain remained highly active. Indonesia’s volcanological survey reported an average of 52 eruptive events per day between May 9 and 16, with ash plumes rising 400 to 4,300 meters (1,300 feet to 14,000 feet) above the summit. NASA and other U.S. government satellites detected thermal anomalies, ash plumes, and sulfur dioxide emissions in recent days. Indonesian authorities have set the alert level at 2 (on a scale of 4) and warned the public to stay at least 4 kilometers (2 miles) from the crater.

Artist’s concept of Phase 3 of NASA’s Moon Base.Credit: NASA During a Moon Base event Tuesday at NASA’s Headquarters in Washington, the agency announced new contracts for lunar rovers for crew to drive and uncrewed cargo landers bound for the Moon. NASA leaders also shared target launch timeframes and upcoming milestones for the first Moon Base infrastructure and exploration missions to the lunar South Pole region ahead of Artemis astronaut landings. “The Moon Base will be America’s and humanity’s first outpost on another celestial world,” said NASA Administrator Jared Isaacman. “Every mission, crewed and uncrewed, will be a learning opportunity as we return to the lunar surface, build the infrastructure to stay, and master the skills required to live and operate in one of the most demanding and dangerous environments imaginable. We will go for the science, for all we stand to gain from an economic and technological perspective, for the innovations that will make life better here on Earth, and to prepare for where we will inevitably go next. We are grateful for President Trump’s leadership, the bipartisan commitment from Congress, our industry and international partners, and the dedicated NASA workforce whose expertise enables us to achieve the near-impossible.” NASA announced the first three Moon Base missions to begin building sustained operations: Moon Base I: Targeted for launch no earlier than fall 2026, this mission will use Blue Origin’s Blue Moon Mark 1 Endurance lander to deliver NASA payloads. Equipment will include the Stereo Cameras for Lunar Plume-Surface Studies instrument to study how thrusters interact with the Moon’s surface, and the Laser Retroreflective Array, which helps orbiting spacecraft determine a more precise location using reflected laser light. The mission will land on the Shackleton Connecting Ridge to demonstrate capabilities that reduce risk for future crewed Artemis landing missions in 2028. Moon Base II: Planned for launch later this year, this mission will deliver more than 1,100 pounds of cargo on Astrobotic’s Griffin lander, including Astrolab’s FLIP rover, to mature mobility systems that inform future lunar terrain vehicle, or LTV, operations. Moon Base III: Also targeted for this year, this mission will fly the first payload selected through NASA’s Payloads and Research Investigations on the Surface of the Moon initiative. Its anchor investigation, Lunar Vertex, will fly on Intuitive Machine’s Nova-C Trinity lunar lander and study lunar swirls, or light spots on the surface of the Moon, to improve understanding of surface evolution and material behavior under extreme conditions. The mission will include payloads from ESA (European Space Agency) and the Korea Astronomy and Space Science Institute, reflecting commercial and international participation in Moon Base activities. These missions are the first of more than a dozen missions that will be announced this year, each designed to generate operational data and reduce risk ahead of crewed Artemis surface activities. NASA has awarded Astrolab $219 million and Lunar Outpost $220 million to build and deliver the first phase of LTVs. Awarded under the Phase 1 High Achievability Mission task orders of the Lunar Terrain Vehicle Services contract, these firm-fixed-price, performance-based milestones will enable NASA to deploy crewed and uncrewed mobility systems to the lunar surface by 2028 through the agency’s CLPS (Commercial Lunar Payload Services) initiative. Early surface mobility is a foundational component of the national space policy priority to create an enduring lunar presence. Astrolab’s Crewed Lunar Vehicle, or CLV‑1, adapted from the company’s FLEX architecture, is a crewed rover designed to transport astronauts, carry supplies, and support remote operations, with a compact stowed configuration, a mass of about 2,000 pounds, and the ability to reach more than 6 mph on level terrain. Complementing this capability, Lunar Outpost’s Pegasus is a lighter, mission‑ready evolution of its Eagle rover designed explicitly to meet NASA’s updated LTV requirements. Operational for up to a year and capable of manual, autonomous, or teleoperated driving at speeds more than 9 mph, Pegasus incorporates Apollo‑heritage technologies and builds on prototype and flight experience to deliver human‑centered mobility essential for establishing a sustained Moon Base. Deploying multiple LTVs early in Moon Base development will accelerate technology demonstrations, inform site planning, and reduce operational risk ahead of crewed Artemis missions, enabling NASA to characterize terrain hazards, move materials, pre-stage resources, and mature systems needed for long-duration lunar exploration. Over the next 18 months, the selected providers will finalize rover designs, conduct crewed evaluations, and qualify flight units for operational readiness, with the resulting LTVs supporting autonomous traverses, terrain preparation, scientific investigations, technology demonstrations, and astronaut transport. As Moon Base efforts advance, NASA will expand opportunities for additional vendors through on‑ramp competitions, fostering a robust, sustainable approach to lunar mobility and strengthening national priorities in space capability. To deliver these rovers to the Moon’s South Pole region, NASA awarded Blue Origin $188 million with an option ******* worth $280.4 million for two task orders, which includes an option ******* based on initial phase performance. NASA can choose to extend the task order for payload delivery. This competitive procurement, executed under the CLPS 1.0 indefinite-delivery/indefinite-quantity framework, the CX-2 task order represents a strategic investment in lunar exploration and will play a critical role in enabling mobility and infrastructure development for sustained lunar operations, marking a significant step toward establishing a permanent human presence on the Moon. Building on the successes and lessons learned from CLPS 1.0, the agency also outlined how the next generation of cargo landers under CLPS 2.0 will continue to deliver payloads to the lunar surface and lunar orbit, supporting NASA’s ambitious goals for sustained lunar operations. This next phase introduces enhanced flexibility, allowing NASA to order turn-key delivery services or start accepting delivery of CLPS hardware for integration into its own missions. The final CLPS 2.0 request for proposal was released on May 15, with responses due on Tuesday, June 30. Moonfall update The agency also shared new updates on MoonFall, a mission that will send four drones to fly short hops on the lunar surface as they survey potential landing sites for Artemis astronauts. NASA‘s Jet Propulsion Laboratory in Southern California has been developing the design and testing prototype hardware and has selected Firefly Aerospace to build the spacecraft that will transport the drones from Earth orbit to the Moon. Launch is targeted for 2028. The drones will independently land on the lunar surface and then gather high-resolution imagery of hard-to-reach terrain over the course of a single lunar day. After each drone’s final flight, its survive-the-night payload will continue to operate for several months, marking a sustained U.S. presence at the lunar South Pole. More robotic missions to come Finally, NASA stated in the coming weeks that a selection of additional CLPS 1.0 task awards, issued during the agency’s Ignition event, for Moon Base payloads and technology demonstrations, is forthcoming. In the coming months, there also will be additional opportunities to compete for CLPS 1.0 and 2.0 task orders as Phase 1 technology demonstrations are defined and planned for Moon Base missions. During the update, NASA leadership reiterated that establishing a sustained lunar presence is aligned with the agency’s broader exploration strategy, supported by increased launch cadence, expanded industry partnerships, and agencywide coordination. As part of the Golden Age of innovation and exploration, NASA will send astronauts on increasingly difficult missions to explore more of the Moon for scientific discovery, economic benefits, and to build on our foundation for the first crewed missions to Mars.

This image shows PUEO at the Long Duration Balloon Facility in Antarctica, immediately after balloon release. Credit: NASA/Scott Battaion The Payload for Ultrahigh Energy Observations (PUEO) is a NASA Astrophysics Pioneers Program mission designed to detect the most energetic particles in the universe. The PUEO mission flew high above Antarctica on a Long Duration Balloon (LDB) and used the Antarctic ice sheet as an enormous detection volume to look for radio signals generated by the interactions of extremely energetic astrophysical neutrinos as they passed through the ice. In addition to searching for the highest energy neutrinos, PUEO could also detect radio signals from high energy cosmic rays showering in Earth’s atmosphere (a.k.a. air showers), either as the signals entered directly into the instrument or reflected off the ice below. The sensitivity achieved with the PUEO instrument was a result of technology advancements and careful optimization of the experimental design to enable accommodation within the balloon platform’s launch volume. The ultra-high energy neutrinos that PUEO was searching for carry information from the most extreme places in the universe, including supermassive ****** holes that accrete matter at the centers of galaxies, neutron star mergers, and other powerful cosmic accelerators. Because these particles travel large distances along straight lines without being absorbed, they provide a unique view of the distant, most energetic universe. Not only will data collected by PUEO reveal the origin and composition of the highest-energy cosmic rays, it will also test fundamental physics at energies far beyond those achievable in human-made particle accelerators on Earth. The PUEO mission built on heritage from the NASA-sponsored Antarctic Impulsive Transient Antenna (ANITA) mission, which had four successful flights from 2006-2016. Like ANITA, PUEO consisted of an array of radio-frequency antennas, an onboard data acquisition system that is triggered by neutrino-like signals and processes and saves the data, and a navigation and command and control system. From its 120,000-foot altitude, PUEO monitored an extremely large volume of Antarctic ice, looking for signals from very rare, high-energy neutrino interactions. The first of NASA’s Astrophysics Pioneers missions to launch, PUEO took off Dec. 20, 2025, from NASA’s Long Duration Balloon Facility near McMurdo Station, Antarctica, and flew for 23 days before landing approximately 120 miles (200 km) from the South Pole. The full payload has been recovered, including the data drives. The PUEO team is currently analyzing the data collected—an undertaking that may take up to a year due to the complex nature of the task. The PUEO mission’s on-ice integration team is seen here in front of the fully constructed instrument. Credit: Cosmin Deaconu The significant improvement in sensitivity achieved with the PUEO instrument compared to that of ANITA was due to a variety of technology advancements and careful optimization of the experimental design to enable accommodation within the balloon platform’s constrained launch volume. Lowering detection threshold with interferometric triggering At the heart of PUEO’s technology advancement was a new type of trigger called an interferometric phased array trigger. The PUEO trigger coherently summed signals from multiple antennas in real time, enabling the instrument to detect weaker signals than previously possible. By lowering the trigger threshold, PUEO could dig further into the noise, and find weaker neutrino and cosmic-ray signals than previous experiments. More channels in a physically constrained space The PUEO antenna collecting area for frequencies above 300 MHz was doubled compared to ANITA, improving the sensitivity to radio emission from particle interactions. To ensure the PUEO payload remained within the allowable launch volume, the team increased the low-frequency cutoff of the PUEO antennas, which enabled them to be even smaller than those used on ANITA. Low-frequency instrument for air shower characterization To improve sensitivity to extensive air showers produced by cosmic rays and potentially neutrinos, PUEO incorporated a new low-frequency instrument that deployed once the payload reached float altitude (it would have been much too large to fit in the allowable launch volume in its flight configuration). This new low-frequency instrument incorporated antennas that are sensitive down to 50 MHz, and extended PUEOs sensitivity to air showers. This photo shows the inside of PUEO’s Main Instrument Enclosure, where many of PUEO’s electronics are housed. Credit: Eric Oberla Many of the technology advancements that were developed for PUEO may also be applicable for mission concepts under development that would use the lunar regolith as a detector for ultra-high energy cosmic rays, and other potential future radio missions on the moon.

These monthly lunar scans help ensure the long-term consistency of Landsat’s Earth observations. Landsat Project Science Support/Ross Walter In April 2026, NASA’s Artemis program took humanity back to the Moon, providing a new look at Earth’s only natural satellite. As the world celebrates the return of Artemis II’s four astronauts, the lunar surface continues to play a critical role in missions much closer to Earth. Since 1972, the NASA/USGS Landsat program has captured the longest continuous record of Earth’s land surface, collecting images that track everything from crop health to glacial change. But with such a long data record, how can scientists trust that images acquired today can be accurately compared to those from days, years, or even decades ago? They look to the Moon. Unlike Earth, with its constantly changing weather, seasons, and landscape, the Moon is remarkably stable. With no atmosphere and virtually no surface changes, the Moon reflects sunlight in a predictable, consistent way. This stability gives engineers a reference to fine-tune Landsat’s instruments and be confident that the data are accurate. Once a month, during the full Moon, the spacecraft turns its instruments away from Earth and points them directly at the lunar surface. Over the course of two orbits, the spacecraft maneuvers to image the moon 15 times. During each pass, Landsat captures detailed measurements of light reflected off the Moon’s surface, revealing any unintended sensor change, or “drift,” that needs correction. The animation above shows the scans acquired by band 4 of the OLI (Operational Land Imager) on Landsat 9 on January 3, 2026. Each parallel scan was acquired by one of the 14 detector modules that comprise the instrument’s focal plane. The satellite maneuvers so that each module images the Moon, with one module capturing it twice. To view this video please enable JavaScript, and consider upgrading to a web browser that supports HTML5 video Landsat Project Science Support/Ross Walter This work is one piece in a complex puzzle called calibration, which is part of what makes NASA the gold standard of science worldwide. From before launch all the way to the end of a satellite’s life, engineers ensure that the data collected by the satellite is accurate and consistent. In addition to looking to the Moon, Landsat also looks to places on Earth where the ground is uniform, like the wide, pale expanse of the White Sands desert in New Mexico. Scientists also collect measurements on the ground to check against those collected from space. For example, they ensure that surface temperature readings match those recorded by Landsat’s thermal band. All these efforts are part of what make a Landsat image different from photos taken by consumer cameras. Landsat images contain crucial information that scientists can use to map changes in habitats, tree species, agricultural patterns, and more.

Earth Observatory Science Earth Observatory An Early “Decoration Day”… Earth Earth Observatory Image of the Day EO Explorer Topics All Topics Atmosphere Land Heat & Radiation Life on Earth Human Dimensions Natural Events Oceans Remote Sensing Technology Snow & Ice Water More Content Collections Global Maps World of Change Articles Notes from the Field Blog Earth Matters Blog Blue Marble: Next Generation EO Kids Mission: Biomes About About Us Subscribe 🛜 RSS Contact Us Search Signs of the racetrack where an early “Decoration Day” event was held are still visible in this image captured by the OLI (Operational Land Imager) on Landsat 9 on April 24, 2026. NASA Earth Observatory/Michala Garrison The origins of Memorial Day lie in the U.S. Civil War, a conflict that led to the deaths of nearly 700,000 Americans. By the waning days of the war, makeshift military cemeteries had sprung up throughout the country, but especially in the South and Mid-Atlantic, where much of the fighting occurred. By the time the leader of the veterans’ group Grand Army of the Republic declared May 30, 1868, as “Decoration Day”—a day for “strewing with flowers or otherwise decorating the graves of comrades who died in the defense of their country”—informal memorials and commemorative events were already happening. The U.S. Department of Veterans Affairs notes that at least 25 places played a role in the early years of the holiday, including Columbus, Mississippi; Macon, Georgia; Columbus, Georgia; Richmond, Virginia; Boalsburg, Pennsylvania; and Carbondale, Illinois. One of the earliest and largest ceremonies documented by historians occurred in Charleston, South Carolina. Confederate control of the badly damaged city had ended in February 1865, and Union troops had emancipated thousands of people there. Among the first tasks taken on was ensuring a proper burial for 257 soldiers found in mass graves near a racetrack at the Washington Race Course and Jockey Club, which had been used as a prison camp during the war. After these soldiers had been re-interred in a new cemetery nearby, a crowd of roughly 10,000 people, including freedmen, missionaries, teachers, and soldiers, assembled at the racetrack and held a parade on May 1, 1865. The day featured thousands of schoolchildren carrying armloads of roses, women bearing flowers and wreaths, double-time marches by troops, choir performances of the “Star-Spangled Banner,” and ****** recitations by local ministers. Much has changed in Charleston since the Civil War. The city has been rebuilt, and it has grown from a pre-war population of 40,000 to 160,000 today. Yet signs of the racetrack in what is now Hampton Park, where the early memorial event took place, remain visible—even to a sensor orbiting Earth on Landsat 9 (above). In 1968, the federal government declared Memorial Day an official national holiday with the Uniform Monday Holiday Act, which moved Decoration Day celebrations from May 30 to the last Monday in May. This act followed a congressional resolution in 1966 that recognized a century of Memorial Day events in Waterloo, New York, acknowledging its claim as the “birthplace” of Memorial Day in honor of a commemorative event held there on May 5, 1866. Hampton Park is visible just north of downtown Charleston in this image captured by the OLI (Operational Land Imager) on Landsat 9 on April 24, 2026.

4 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) NASA crew chief Walt Kondracki checks an F-15 aircraft Tuesday, March 17, 2026, at NASA’s Armstrong Flight Research Center in Edwards, California. Ground crews, made of various roles, maintain the aircraft to be ready for each mission.NASA/Carla Escamilla From high‑speed research flights to high‑altitude science campaigns, NASA depends on aircraft that perform at their best and the ground crews who keep them mission ready. At NASA’s Armstrong Flight Research Center in Edwards, California, specially trained maintenance crews are essential to keeping the agency’s aircraft flying safely and reliably. This year, NASA added two F-15s and a Pilatus PC-12 to its fleet at Armstrong. These aircraft – alongside platforms such as the high-altitude ER-2s and NASA’s newest X-plane, the X-59 – reflect a wide range of capabilities. The maintenance staff is responsible for keeping each one mission ready. NASA pilot Nils Larson, left, walks next to crew chief Walt Kondracki, right, by an F-15 aircraft Tuesday, Jan. 13, 2026, at NASA’s Armstrong Flight Research Center in Edwards, California. In the background, NASA mechanic Tim Logan secures the cockpit inside of the F-15, and flight test engineer A.J. Jaffe stands to the right.NASA/Christopher LC Clark “That’s the beauty of our Armstrong maintenance teams. They adapt to any type of change,” said Jose “Manny” Rodriguez, NASA Armstrong Gulfstream G-IV crew chief. “One day you could have an instrument being loaded, and the next day it may be aircraft reconfiguration, all while other aircraft systems may need fixing. They adapt and they overcome any situation.” Each aircraft supports a specific mission, whether it’s conducting science research, serving as a support or chase aircraft, or assisting NASA rocket launches. The aircraft fly at different speeds, carry specialized hardware, and require maintenance crews to stay agile with fast-paced changes. To ensure NASA can make aeronautics and science advancements safely, the crews work continuously, checking on the ejection seats, filling the tanks with fuel, and changing out brakes, wheels, wiring, and hardware constantly, all of which can degrade with each flight. From left, NASA avionics technician Jesse Orellana; quality assurance employee Jose Prieto; mechanic Francisco Rodriguez; and mechanic Vincent Moreno work on an ER-2 aircraft Monday, Jan. 26, 2026, at NASA’s Armstrong Flight Research Center in Edwards, California.NASA/Christopher LC Clark On any given day, an aircraft may be flight-ready for a mission, undergoing scheduled maintenance or modifications, or down for longer-term care. There are typically multiple NASA Armstrong aircraft in the air in one day. Currently, the center’s C-20A is flying in Peru and Panama, the X-59 is often flying twice per day with a chase plane, and the center’s ER-2 is flying in Colorado, supporting the Geological Earth Mapping Experiment (GEMx). All this work is happening at the same time, and Armstrong’s skilled maintenance staff is prepping and fixing aircraft as needed along the way. The team includes mechanics with both military and civilian backgrounds, and the job involves a lot of on-the-job training. Maintenance crews are composed of: a crew chief – the person in charge of the airplane an avionics technician, who specializes in navigation, communication, and flight control systems quality assurance personnel, who oversee the work being done additional mechanics assigned to each airplane After the maintenance crew ensures the aircraft is in the best condition possible, the team tows it out to the flightline, and it becomes ready for operations. The NASA pilot assigned to the mission will walk around the aircraft with the assigned crew chief for a final safety check before flight. “There is a crew chief assigned to every aircraft,” Rodriguez said. “The crew chief is responsible for the integrity of that aircraft, and at the end of the day, his signature and the pilot’s together are what constitutes that the aircraft is safe for flight.” Maintenance crews track each flight to help ensure it completes the mission without returning early. If an aircraft does return to base early, the maintenance team stands ready. When it lands, the crew is right there again, helping the research team complete the mission and fixing whatever is needed to stay nimble and ready for the next flight. “It’s difficult at times to work with different airplanes from both the civilian and military sides, but it’s very rewarding to see that we have the capability and the expertise to keep these aircraft flying,” Rodriguez said.

NASA’s Jet Propulsion Laboratory in Southern California.Credit: NASA NASA announced plans Friday to compete the next contract for managing and operating the agency’s federally funded research and development center (FFRDC) in Southern California at the Jet Propulsion Laboratory (JPL), to ensure continued accountability and strong value for U.S. taxpayers. The California Institute of Technology (Caltech) has managed the laboratory since its inception in the 1930’s, and previous NASA contracts for its management and operations have been awarded sole source to the university since the facility was transferred from the U.S. Army to NASA in 1958. The rapid growth of the U.S. space economy indicates there may now be a viable competitive market for programmatic and institutional elements of the FFRDC operations. Conducting a competition for this contract enables NASA to assess the potential benefits of alternative management approaches to the FFRDC, including opportunities to enhance mission performance, innovation, and overall cost and operational efficiency, consistent with federal competition requirements. This decision is part of a broader governmentwide and agency effort to find efficiencies, strengthen performance, and drive mission outcomes faster and more affordably. “The Jet Propulsion Laboratory has delivered some of the most extraordinary scientific and engineering achievements in NASA’s history,” said NASA Administrator Jared Isaacman. “As America’s space economy evolves, we have a responsibility to the American people and the scientific community to evaluate how we can execute faster, operate more efficiently, and continue to deliver world-class science and engineering at the highest level. The decision to compete this contract reflects NASA’s commitment to strong stewardship of taxpayer resources and positions Jet Propulsion Laboratory to continue driving world-changing scientific discovery and technological innovation for decades to come.” The work conducted at JPL remains critically important to the agency, and NASA is committed to maintaining continuity for active and future missions throughout the procurement process. NASA also is committed to maintaining the FFRDC’s existing physical location. This approach is consistent with broader government practices, including at the Department of Energy, which has held full and open competitions for five of its 16 FFRDC management and operations contracts over the past 10 years. The current contract with Caltech began Oct. 1, 2018, and runs through Sept. 30, 2028, with a potential maximum value of $30 billion, if all options are exercised. NASA has initiated the procurement process to compete the contract. Beginning this process now allows the agency sufficient time to conduct a comprehensive competition and award cycle while maintaining continuity for ongoing missions and laboratory operations.

Credit: NASA NASA announced Friday an agencywide realignment to increase mission focus and move out on the National Space Policy. These changes position the agency to better deliver on the nation’s highest‑priority objectives with speed and efficiency. During the Ignition event in late March, NASA Administrator Jared Isaacman and agency leaders outlined the most pressing objectives to deliver on the next chapter of American leadership in space. President Trump’s Executive Order Ensuring American Space Superiority, otherwise known as the National Space Policy, directed NASA to focus talent and resources on objectives including accelerating the Artemis program, establishing a Moon Base, developing a nuclear space reactor, igniting the orbital economy, and expanding missions of science and discovery. To support the agency’s ambitious short- and long-term goals, NASA is taking action to increase specialization at centers and integrate mission directorates, elevating delivery of technically excellent work. Some of these actions include: Center directors will continue reporting to Associate Administrator Amit Kshatriya, empowered to foster the unique capabilities of each center, and strengthen investments in infrastructure and the health of their workforce. Mission directorates will now report directly to the administrator, ensuring focus on the mission and enabling them to leverage resources across centers, industry, and international partnerships with greater speed and efficiency. The associate administrator also now serves as NASA chief engineer, reinforcing the agency’s technical backbone and ensuring continuity and autonomy in critical engineering decisions. The agency continues to focus on rebuilding core competencies, insourcing contractors to civil servants where appropriate, strengthening the intern pipeline, and leveraging the agency’s joint recruitment initiative with the U.S. Office of Personnel Management, NASA Force, to build a strong, sustainable workforce for generations to come. “This initiative reflects NASA’s extreme focus on executing the mission in direct support of the National Space Policy. We are focusing resources on the most pressing objectives only NASA is capable of undertaking and liberating the workforce from unnecessary bureaucracy and obstacles that impede progress. We aim to rebuild competencies and instill a culture that attracts the best and brightest capable of pursuing the most demanding engineering challenges and moving safely and urgently,” said Isaacman. “There will be no reduction in force, no program cancellations no closures, but we will achieve cost savings through more efficient execution and taking an active role in delivering the outcomes the world has been waiting for from NASA. This is how we deliver on the mission, meet the moment, and continue to make history on behalf of the American people.” Mission directorate realignment is as follows: Human Spaceflight Mission Directorate (HSMD): With human spaceflight operational to both low Earth orbit and the Moon, the Exploration Systems Development Mission Directorate and Space Operations Mission Directorate will unify as HSMD. Research and Technology Mission Directorate (RTMD): NASA will integrate the Aeronautics Research Mission Directorate and Space Technology Mission Directorate into the new RTMD. As a combined research, space technology, and aeronautics organization charged with nuclear power and propulsion development, RTMD will ensure NASA has the capabilities needed for the mission of today and the future. Science Mission Directorate (SMD): Remains unchanged and continues to provide the foundation for NASA’s world‑leading scientific discovery.

4 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) Researchers Dr. Kevin Yu, left, and Dr. Jamesa Stokes prepare to remove a sample of a new material they discovered from a furnace inside a laboratory at NASA’s Glenn Research Center in Cleveland in October 2024. Quenching, or bringing the temperature of the sample down as quickly as possible, helps to ensure no more reactions occur as the sample cools so scientists can focus on studying how it behaves at high temperatures.NASA/Jef Janis A material recently discovered and tested at NASA’s Glenn Research Center in Cleveland could help astronauts pack lighter for future missions to the Moon. NASA is researching ways explorers could “live off the land” by harnessing lunar resources, including melting Moon rocks to extract metals for building infrastructure and oxygen for fuel and life support. As part of a graduate fellowship through the agency’s Space Technology Graduate Research Opportunities, Dr. Kevin Yu, who now works as a technologist at NASA’s Jet Propulsion Laboratory in Southern California, teamed up with Dr. Jamesa Stokes, a materials research engineer at NASA Glenn, to study how a variety of substances interacted with liquefied Moon dust. You could call it lava, because it’s basically rocks that are crushed up and then melted. It’s very corrosive, and it will very quickly eat through a lot of commonly used refractory, or heat-resistant, materials. Dr. kevin yu Technologist at NASA's Jet Propulsion Laboratory About six months into their research, Stokes and Yu realized they’d stumbled across something promising and entirely new. After combining simulated lunar dust with a compound called scandium oxide and heat treating the mixture using a red-hot furnace, they discovered that an unknown material had formed. The researchers checked and double-checked their work, but the material didn’t match any of the more than 1 million substances in their X-ray analysis database. A sample of the new material researchers discovered at NASA’s Glenn Research Center in Cleveland sits inside a platinum crucible, or heat-resistant container, after being removed from a high-temperature furnace. Behind the silver-colored container is a dome that protects the sample during handling.NASA/Jef Janis Nothing about the material had ever been studied before, so the team started from scratch, measuring the substance’s chemical composition. To make small, isolated samples and continue testing how it reacted with molten Moon dust, they used special grinding and mixing equipment in their laboratory to crush up around eight basic oxide components in ethyl alcohol before baking the mixture at more than 2,900 degrees Fahrenheit inside the furnace. “It’s actually a very cool-looking powder; it goes in pink, almost like strawberry milk,” Yu said. “It has a built-in color indicator, so by the time you’re done with it, it turns to a light beige or tan color, and that’s how you know the reaction has proceeded the way you wanted it to.” The pink powder shown at the far right is used to make the new material researchers discovered at NASA’s Glenn Research Center in Cleveland. The other powders to the left are two types of simulated Moon dirt used to represent dust from both the brighter regions of its surface (referred to as lunar highlands) and the darker regions (referred to as lunar maria).NASA/Jef Janis After analyzing their results, the team found that the new substance isn’t corroded too quickly by the molten Moon dirt and can withstand the high temperatures needed to melt it — up to six times hotter than the oven in your kitchen. While it’s made with scandium oxide, which can be expensive, it costs much less than precious metals like platinum that would normally be used in these types of high-temperature processes. The researchers’ insights could help influence NASA’s designs for a future technology that would extract resources from Moon rocks, and the new material could be used to make the pipes or basins holding molten dust inside this potential technology. The new material’s characteristics also could prove ideal for making coatings that protect parts inside of jet engines, which can reach similarly scorching temperatures. The researchers found it is lighter, less dense, and better at insulating heat than current state-of-the-art coating materials. Researchers Dr. Jamesa Stokes, left, and Dr. Kevin Yu pose for a portrait inside of a laboratory at NASA’s Glenn Research Center in Cleveland in October 2024.NASA/Jef Janis While Yu and Stokes have now completed their initial tests, they hope to fine-tune the material in the future to purify it and make it even more affordable to produce. Materials research will be integral to exploring the harsh environments of the Moon and beyond. You can have the best idea in the world for a structure or a vehicle, but if you don’t have the materials that have the right properties to make your vision come true, it’s not going to succeed no matter how well you design it. Dr. Jamesa stokes Materials Research Engineer at NASA Glenn Studying new materials also advances NASA’s work on Earth. “I think trying to push what’s possible with materials also allows for a lot of breakthroughs on the terrestrial side. Having a better understanding of materials for all sorts of applications is what gets me excited to go to work in the morning,” Yu said. “That’s why I love NASA’s mission; it’s for the benefit of all.” This materials research is supported by NASA’s Space Technology Mission Directorate and NASA’s Aeronautics Research Mission Directorate.

NASA, ESA, H. Ebeling (University of Hawaii); Image Processing: G. Kober (NASA/Catholic University of America) Look closely at this image from NASA’s Hubble Space Telescope and you’ll see galaxies of various shapes and sizes clustered together toward the center-left of the image. A few foreground stars shine brightly and are easily distinguished by the spikes that appear to extend outward from each star. These spikes, called diffraction spikes, are the result of how point sources of light (such as stars) bend, or diffract, around the supports for Hubble’s secondary mirror. Hubble captured this scene of MACS J1141.6-1905 in visible and infrared light. The image includes data from two Hubble observing programs that looked at massive galaxy clusters that shine very brightly in X-rays. Both programs were looking for distant galaxies gravitationally lensed by the cluster. They also wanted to better understand the physical nature of interactions at each cluster’s core. An extra bonus was the addition of Hubble’s visible and infrared observations of these very bright X-ray clusters to its archive. Hubble’s archive of 1.7 million observations, and counting, is a valuable tool for current and future astronomers. They can mine Hubble’s 36 years of observations and examine the data with new tools, enabling researchers to make new discoveries. MACS J1141.6-1905 is around four billion light-years away in the constellation Crater (the Cup).

NASA Earth Observatory/Lauren Dauphin A powerful supercell storm produced multiple tornadoes across southern Mississippi on May 6, 2026. The longest and most powerful spanned five counties, delivering wind speeds up to 137 miles (220 kilometers) per hour and EF-3 damage, as gauged by the Enhanced Fujita Scale, to several areas. Part of this tornado’s destructive path was visible to the Landsat 8 satellite when it passed over the area on May 12. Winds snapped, uprooted, and tore bark and branches off trees, creating a brownish track across the landscape. This area, south of Brookhaven in Lincoln County, was one that sustained EF-3 damage. National Weather Service (NWS) post-event damage assessments noted extensive tree damage, a home whose exterior walls collapsed, and a mobile home park “devastated with debris.” The tornado covered much more ground than is captured in this scene. It began in St. Catherine Creek National Wildlife Refuge near the Mississippi River, approximately 60 miles (100 kilometers) west-southwest of Brookhaven. In just over two hours, it traveled nearly 82 miles (132 kilometers), placing it among some of the longest tornadoes recorded in Mississippi. Heavy tree damage occurred along its entire path, NWS surveys found, with several instances of EF-2 structural damage and bent or collapsed transmission towers. Seven tornadoes occurred in Mississippi on the evening of May 6, according to NWS preliminary data as of May 20. The Mississippi Emergency Management Agency received reports of damage to more than 400 homes and dozens of businesses and farm buildings statewide after the storms, according to a news release, the majority of which were in Lincoln County. The Gulf Coast and other southeastern states are not considered part of what’s commonly known as Tornado Alley, an area encompassing much of the U.S. central and southern plains where supercells tend to form. However, this belt of southeastern states is also tornado-prone, experiencing a relatively high frequency of tornadoes in spring and late autumn. Historically in Mississippi, the most monthly tornadoes—an average of more than seven—occur in April, while May averages just over three. Some recent analyses have found decreases in tornado frequency in the Great Plains and increases in the Southeast over several decades.

Representatives of the Artemis Accords signatories including the United States, led by NASA and the U.S. Department of State, met May 13–14, 2026, in Lima for the fourth annual Artemis Accords workshop.Credit: Ministry of Foreign Affairs of Peru and Peruvian Space Agency (CONIDA) The United States participated in an Artemis Accords workshop in Lima, Peru, last week, following a new wave of nations committing to safe and responsible exploration of the Moon, Mars, and beyond. Leading up to the event, six countries, including Latvia, Jordan, Morocco, Malta, Ireland, and Paraguay, joined the growing coalition of Artemis Accords signatories during ceremonies held at NASA Headquarters and abroad. This brings the total number of Artemis Accords signatories to 67 like-minded nations. “This gathering showcases the remarkable global momentum behind the Artemis Accords and our Artemis program,” said NASA Administrator Jared Isaacman. “The Artemis Accords were created in President Trump’s first term and, as we execute his National Space Policy, we are putting these principles into practice. By aligning our capabilities, acting with urgency, and moving forward as partners, these signatory countries will help shape the future, not from the sidelines, but as essential contributors to humanity’s first permanent outpost on the Moon. Each and every Artemis Accords signatory has the opportunity to play a meaningful role with NASA as we work together to build a sustained human presence on the surface of the Moon.” On May 13-14, representatives from NASA and the U.S. Department of State joined dozens of counterparts from 30 countries, including several of the newest signatories, for technical discussions and a tabletop exercise focused on operating in complex lunar environments. Peru hosted the fourth annual workshop, marking the first time the gathering has taken place in South America. “One of our objectives in hosting this edition of the workshops in our country was to increase regional participation,” said Maj. Gen. Roberto Melgar Sheen, director of Peruvian Space Agency (CONIDA). “I am pleased to say that we have achieved this: All South American signatory countries are taking part in this event, with 90% participating in person and 10% virtually.” The Artemis Accords community reviewed planned lunar landing and orbiting missions from all the signatories in attendance. With more than a dozen lunar landing missions expected over the next 18 months, last week’s discussions and tabletop exercises focused on non-interference, interoperability, release of scientific data, orbital debris and mitigation. These conversations included a presentation on NASA’s exploration plan, which accelerates the agency’s missions to the Moon. Artemis Accords signatories now have expanded opportunities to support NASA’s Moon Base and deepen their participation in the broader Artemis program, following the agency’s Ignition event on March 24. “Peru joined the Artemis Accords in 2024, aiming to participate in a cutting-edge dialogue mechanism that addresses global trends in space exploration. We aspire to forge cooperative ties with the signatories of the Artemis Accords that contribute to the scientific and aerospace development of our country,” said Peru’s Vice Minister of Foreign Affairs Ambassador Felix Denegri about the workshop. During the first Trump Administration, the United States, led by NASA and the U.S. State Department, joined with seven other founding nations in 2020 to establish the Artemis Accords in response to the growing interest in lunar activities by both governments and private companies. Today, countries representing every region of the world have committed to responsible principles for exploration. Signing the Artemis Accords means a commitment to the peaceful and transparent exploration of space; rendering aid to those in need; enabling access to scientific data; ensuring activities do not interfere with those of others; and preserving historically significant sites and artifacts by developing best practices. More countries are expected to sign the Artemis Accords in the months and years ahead, as NASA continues its work to establish a safe, peaceful, and prosperous future in space.
