Earth scientist Compton J. Tucker has been elected to the National Academy of Sciences for his work creating innovative tools to track the planet’s changing vegetation from space. It’s research that has spanned nearly 50 years at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, where he is a visiting scientist after retiring in March. 

Tucker’s research began with identifying wavelengths of light that are absorbed or reflected as plants undergo photosynthesis, and has evolved into calculating the health and productivity of vegetation over time with satellites. 

“I’m honored and surprised,” Tucker said of his election. “There were opportunities at the Goddard Space Flight Center that have enabled this work that couldn’t be found elsewhere. There were people who built satellites, who understood satellite data, and had the computer code to process it. All the work I’ve done has been part of a team, with other people contributing in different ways. Working at NASA is a team effort of science and discovery that’s fun and intellectually rewarding.”

Tucker earned his master’s and doctoral degrees from Colorado State University, where he worked on a National Science Foundation-funded project analyzing spectrometer data of grassland ecosystems. In 1975, he came to NASA Goddard as a postdoctoral fellow and used what he learned in his graduate work to modify the imager on National Oceanic and Atmospheric Administration (NOAA) meteorological satellites and modify Landsat’s thematic mapper instrument. 

He became a civil servant at the agency in 1977, and continued work with radiometers to study vegetation – first with handheld devices, then with NOAA’s Advanced Very High Resolution Radiometer satellite instruments.  He has also used data from Landsat satellites, Moderate Resolution Imaging Spectroradiometer instruments, and commercial satellites. His scientific papers have been cited 100,000 times, and one of his recent studies mapped 10 billion individual trees across Africa’s drylands to inventory carbon storage at the tree level.

“The impact of Compton Tucker’s work over the last half-century at Goddard is incredible,” said Dalia Kirschbaum, director of the Earth Sciences Division at NASA Goddard. “Among his many achievements, he essentially developed the technique of using satellites to study photosynthesis from plants, which people have used to monitor droughts, forecast crop shortages, defeat the desert locust, and even predict disease outbreaks. This is a well-deserved honor.”

The National Academy of Sciences was proposed by Abraham Lincoln and established by Congress in 1863, charged with advising the United States on science and technology. Each year, up to 120 new members are elected “in recognition of their distinguished and continuing achievements in original research,” according to the organization.

In addition his role as a visiting scientist at Goddard, Tucker is also an adjunct professor at the University of Maryland and a consulting scholar at the University of Pennsylvania’s University Museum. He was awarded the National Air and Space Collins Trophy for Current Achievement in 1993 and the Vega Medal by the Swedish Society of Anthropology and Geography in 2014. He is a fellow of the American Association for the Advancement of Science and the American Geophysical Union, and won the Senior Executive Service Presidential Rank Award for Meritorious Service in 2017, among other honors.

NASA’s PACE Mission Reveals a Year of Terrestrial Data on Plant Health

4 min read

Preparations for Next Moonwalk Simulations Underway (and Underwater)

A lot can change in a year for Earth’s forests and vegetation, as springtime and rainy seasons can bring new growth, while cooling temperatures and dry weather can bring a dieback of those green colors. And now, a novel type of NASA visualization illustrates those changes in a full complement of colors as seen from space.

Researchers have now gathered a complete year of PACE data to tell a story about the health of land vegetation by detecting slight variations in leaf colors. Previous missions allowed scientists to observe broad changes in chlorophyll, the pigment that gives plants their green color and also allows them to perform photosynthesis. But PACE now allows scientists to see three different pigments in vegetation: chlorophyll, anthocyanins, and carotenoids. The combination of these three pigments helps scientists pinpoint even more information about plant health. Credit: NASA’s Goddard Space Flight Center

NASA’s Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) satellite is designed to view Earth’s microscopic ocean plants in a new lens, but researchers have proved its hyperspectral use over land, as well.

Previous missions measured broad changes in chlorophyll, the pigment that gives plants their green color and also allows them to perform photosynthesis. Now, for the first time, PACE measurements have allowed NASA scientists and visualizers to show a complete year of global vegetation data using three pigments: chlorophyll, anthocyanins, and carotenoids. That multicolor imagery tells a clearer story about the health of land vegetation by detecting the smallest of variations in leaf colors.

“Earth is amazing. It’s humbling, being able to see life pulsing in colors across the whole globe,” said Morgaine McKibben, PACE applications lead at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “It’s like the overview effect that astronauts describe when they look down at Earth, except we are looking through our technology and data.”

Anthocyanins are the red pigments in leaves, while carotenoids are the yellow pigments – both of which we see when autumn changes the colors of trees. Plants use these pigments to protect themselves from fluctuations in the weather, adapting to the environment through chemical changes in their leaves. For example, leaves can turn more yellow when they have too much sunlight but not enough of the other necessities, like water and nutrients. If they didn’t adjust their color, it would damage the mechanisms they have to perform photosynthesis.

In the visualization, the data is highlighted in bright colors: magenta represents anthocyanins, green represents chlorophyll, and cyan represents carotenoids. The brighter the colors are, the more leaves there are in that area. The movement of these colors across the land areas show the seasonal changes over time.

In areas like the evergreen forests of the Pacific Northwest, plants undergo less seasonal change. The data highlights this, showing comparatively steadier colors as the year progresses.

The combination of these three pigments helps scientists pinpoint even more information about plant health.

“Shifts in these pigments, as detected by PACE, give novel information that may better describe vegetation growth, or when vegetation changes from flourishing to stressed,” said McKibben. “It’s just one of many ways the mission will drive increased understanding of our home planet and enable innovative, practical solutions that serve society.”

The Ocean Color Instrument on PACE collects hyperspectral data, which means it observes the planet in 100 different wavelengths of visible and near infrared light. It is the only instrument – in space or elsewhere – that provides hyperspectral coverage around the globe every one to two days. The PACE mission builds on the legacy of earlier missions, such as Landsat, which gathers higher resolution data but observes a fraction of those wavelengths.

In a paper recently published in Remote Sensing Letters, scientists introduced the mission’s first terrestrial data products.

“This PACE data provides a new view of Earth that will improve our understanding of ecosystem dynamics and function,” said Fred Huemmrich, research professor at the University of Maryland, Baltimore County, member of the PACE science and applications team, and first author of the paper. “With the PACE data, it’s like we’re looking at a whole new world of color. It allows us to describe pigment characteristics at the leaf level that we weren’t able to do before.”

As scientists continue to work with these new data, available on the PACE website, they’ll be able to incorporate it into future science applications, which may include forest monitoring or early detection of drought effects.

NASA Satellite Images Could Provide Early Volcano Warnings 

5 min read

Preparations for Next Moonwalk Simulations Underway (and Underwater)

Chaitén Volcano in southern Chile erupted on May 2, 2008 for the first time in 9,000 years. NASA satellites that monitor changes in vegetation near volcanoes could aid in earlier eruption warnings.
Jeff Schmaltz, MODIS Rapid Response Team, NASA Goddard Space Flight Center

Scientists know that changing tree leaves can indicate when a nearby volcano is becoming more active and might erupt. In a new collaboration between NASA and the Smithsonian Institution, scientists now believe they can detect these changes from space.

As volcanic magma ascends through the Earth’s crust, it releases carbon dioxide and other gases which rise to the surface. Trees that take up the carbon dioxide become greener and more lush. These changes are visible in images from NASA satellites such as Landsat 8, along with airborne instruments flown as part of the Airborne Validation Unified Experiment: Land to Ocean (AVUELO).

Ten percent of the world’s population lives in areas susceptible to volcanic hazards. People who live or work within a few miles of an eruption face dangers that include ejected rock, dust, and surges of hot, toxic gases. Further away, people and property are susceptible to mudslides, ashfalls, and tsunamis that can follow volcanic blasts. There’s no way to prevent volcanic eruptions, which makes the early signs of volcanic activity crucial for public safety. According to the U.S. Geological Survey, NASA’s Landsat mission partner, the United States is one of the world’s most volcanically active countries.

When magma rises underground before an eruption, it releases gases, including carbon dioxide and sulfur dioxide. The sulfur compounds are readily detectable from orbit. But the volcanic carbon dioxide emissions that precede sulfur dioxide emissions – and provide one of the earliest indications that a volcano is no longer dormant – are difficult to distinguish from space. 

The remote detection of carbon dioxide greening of vegetation potentially gives scientists another tool — along with seismic waves and changes in ground height—to get a clear idea of what’s going on underneath the volcano. “Volcano early warning systems exist,” said volcanologist Florian Schwandner, chief of the Earth Science Division at NASA’s Ames Research Center in California’s Silicon Valley, who had teamed up with climate scientist Josh Fisher of Chapman University in Orange, California and volcanologist Robert Bogue of McGill University in Montreal a decade ago. “The aim here is to make them better and make them earlier.”

“Volcanoes emit a lot of carbon dioxide,” said Bogue, but there’s so much existing carbon dioxide in the atmosphere that it’s often hard to measure the volcanic carbon dioxide specifically. While major eruptions can expel enough carbon dioxide to be measurable from space with sensors like NASA’s Orbiting Carbon Observatory 2, detecting these much fainter advanced warning signals has remained elusive.  “A volcano emitting the modest amounts of carbon dioxide that might presage an eruption isn’t going to show up in satellite imagery,” he added.

Because of this, scientists must trek to volcanoes to measure carbon dioxide directly. However, many of the roughly 1,350 potentially active volcanoes worldwide are in remote locations or challenging mountainous terrain. That makes monitoring carbon dioxide at these sites labor-intensive, expensive, and sometimes dangerous. 

Volcanologists like Bogue have joined forces with botanists and climate scientists to look at trees to monitor volcanic activity. “The whole idea is to find something that we could measure instead of carbon dioxide directly,” Bogue said, “to give us a proxy to detect changes in volcano emissions.”

“There are plenty of satellites we can use to do this kind of analysis,” said volcanologist Nicole Guinn of the University of Houston. She has compared images collected with Landsat 8, NASA’s Terra satellite, ESA’s (European Space Agency) Sentinel-2, and other Earth-observing satellites to monitor trees around the Mount Etna volcano on the coast of Sicily. Guinn’s study is the first to show a strong correlation between tree leaf color and magma-generated carbon dioxide.

Confirming accuracy on the ground that validates the satellite imagery is a challenge that Fisher is tackling with surveys of trees around volcanoes. During the March 2025 Airborne Validation Unified Experiment: Land to Ocean mission with NASA and the Smithsonian Institution scientists deployed a spectrometer on a research plane to analyze the colors of plant life in Panama and Costa Rica.

Fisher directed a group of investigators who collected leaf samples from trees near the active Rincon de la Vieja volcano in Costa Rica while also measuring carbon dioxide levels. “Our research is a two-way interdisciplinary intersection between ecology and volcanology,” Fisher said. “We’re interested not only in tree responses to volcanic carbon dioxide as an early warning of eruption, but also in how much the trees are able to take up, as a window into the future of the Earth when all of Earth’s trees are exposed to high levels of carbon dioxide.”

Relying on trees as proxies for volcanic carbon dioxide has its limitations. Many volcanoes feature climates that don’t support enough trees for satellites to image. In some forested environments, trees respond differently to changing carbon dioxide levels. And fires, changing weather conditions, and plant diseases can complicate the interpretation of satellite data on volcanic gases.

Still, Schwandner has witnessed the potential benefits of volcanic carbon dioxide observations first-hand. He led a team that upgraded the monitoring network at Mayon volcano in the Philippines to include carbon dioxide and sulfur dioxide sensors. In December 2017, government researchers in the Philippines used this system to detect signs of an impending eruption and advocated for mass evacuations of the area around the volcano. Over 56,000 people were safely evacuated before a massive eruption began on January 23, 2018. As a result of the early warnings, there were no casualties.

Using satellites to monitor trees around volcanoes would give scientists earlier insights into more volcanoes and offer earlier warnings of future eruptions. “There’s not one signal from volcanoes that’s a silver bullet,” Schwandner said. “And tracking the effects of volcanic carbon dioxide on trees will not be a silver bullet. But it will be something that could change the game.”

NASA-Led Study Pinpoints Areas Sinking, Rising Along California Coast

5 min read

Preparations for Next Moonwalk Simulations Underway (and Underwater)

San Simeon
Cliffs slope into the ocean in San Simeon, California. All along the state’s dynamic coastline, land is inching down and up due to natural and human-caused factors. A better understanding of this motion can help communities prepare for rising seas.
NASA/JPL-Caltech

The elevation changes may seem small — amounting to fractions of inches per year — but they can increase or decrease local flood risk, wave exposure, and saltwater intrusion.

Tracking and predicting sea level rise involves more than measuring the height of our oceans: Land along coastlines also inches up and down in elevation. Using California as a case study, a NASA-led team has shown how seemingly modest vertical land motion could significantly impact local sea levels in coming decades.

By 2050, sea levels in California are expected to increase between 6 and 14.5 inches (15 and 37 centimeters) higher than year 2000 levels. Melting glaciers and ice sheets, as well as warming ocean water, are primarily driving the rise. As coastal communities develop adaptation strategies, they can also benefit from a better understanding of the land’s role, the team said. The findings are being used in updated guidance for the state.

“In many parts of the world, like the reclaimed ground beneath San Francisco, the land is moving down faster than the sea itself is going up,” said lead author Marin Govorcin, a remote sensing scientist at NASA’s Jet Propulsion Laboratory in Southern California. 

The new study illustrates how vertical land motion can be unpredictable in scale and speed; it results from both human-caused factors such as groundwater pumping and wastewater injection, as well as from natural ones like tectonic activity. The researchers showed how direct satellite observations can improve estimates of vertical land motion and relative sea level rise. Current models, which are based on tide gauge measurements, cannot cover every location and all the dynamic land motion at work within a given region.

Local Changes

Researchers from JPL and the National Oceanic and Atmospheric Administration (NOAA) used satellite radar to track more than a thousand miles of California coast rising and sinking in new detail. They pinpointed hot spots including cities, beaches, and aquifers at greater exposure to rising seas now and in coming decades.

To capture localized motion inch by inch from space, the team analyzed radar measurements made by ESA’s (the European Space Agency’s) Sentinel-1 satellites, as well as motion velocity data from ground-based receiving stations in the Global Navigation Satellite System. Researchers compared multiple observations of the same locations made between 2015 to 2023 using a processing technique called interferometric synthetic aperture radar (InSAR).

Scientists mapped land sinking in coastal California cities

NASA Earth Observatory

Homing in on the San Francisco Bay Area specifically, San Rafael, Corte Madera, Foster City, and Bay Farm Island the team found the land subsiding at a steady rate of more than 0.4 inches (10 millimeters) per year due largely to sediment compaction. Accounting for this subsidence in the lowest-lying parts of these areas, local sea levels could rise more than 17 inches (45 centimeters) by 2050. That’s more than double the regional estimate of 7.4 inches (19 centimeters) based solely on tide gauge projections.

Not all coastal locations in California are sinking. The researchers mapped uplift hot spots of several millimeters per year in the Santa Barbara groundwater basin, which has been steadily replenishing since 2018. They also observed uplift in Long Beach, where fluid extraction and injection occur with oil and gas production.

The scientists further calculated how human-induced drivers of local land motion increase uncertainties in the sea level projections by up to 15 inches (40 centimeters) in parts of Los Angeles and San Diego counties. Reliable projections in these areas are challenging because the unpredictable nature of human activities, such as hydrocarbon production and groundwater extraction, necessitating ongoing monitoring of land motion.  

Fluctuating Aquifers, Slow-Moving Landslides

In the middle of California, in the fast-sinking parts of the Central Valley (subsiding as much as 8 inches, or 20 centimeters, per year), land motion is influenced by groundwater withdrawal. Periods of drought and precipitation can alternately draw down or inflate underground aquifers. Such fluctuations were also observed over aquifers in Santa Clara in the San Francisco Bay Area, Santa Ana in Orange County, and Chula Vista in San Diego County.

Along rugged coastal terrain like the Big Sur mountains below San Francisco and Palos Verdes Peninsula in Los Angeles, the team pinpointed local zones of downward motion associated with slow-moving landslides. In Northern California they also found sinking trends at marshlands and lagoons around San Francisco and Monterey bays, and in Sonoma County’s Russian River estuary. Erosion in these areas likely played a key factor.

Scientists, decision-makers, and the public can monitor these and other changes occurring via the JPL-led OPERA (Observational Products for End-Users from Remote Sensing Analysis) project. The OPERA project details land surface elevational changes across North America, shedding light on dynamic processes including subsidence, tectonics, and landslides.

The OPERA project will leverage additional state-of-the-art InSAR data from the upcoming NISAR (NASA-Indian Space Research Organization Synthetic Aperture Radar) mission, expected to launch within the coming months.

Smart windows take a page from nature's pinecone playbook

Have you ever wondered how a pine cone knows when to open and close? It's not magic, it's science

Now, researchers have taken this cue from nature to create something pretty cool for our homes. 

Let's dive into how this revolutionary window technology works, keeping your home comfortable without using a single watt of electricity.

Pine cones have these amazing scales that respond to moisture. When it's damp, they close up tight. But when it's warm and dry, they open wide to release their seeds. This simple yet effective mechanism has inspired scientists to develop a smart window system that could change the way we think about energy efficiency in buildings.

SOLAR DEVICE TRANSFORMS USED TIRES TO HELP PURIFY WATER SO THAT ITS DRINKABLE

Scientists from Germany's universities of Stuttgart and Freiburg have developed what is known as the Solar Gate window facade system. It's like having tiny pinecones built right into your windows. These smart windows have special elements that curl up when it's cool and moist, letting in sunlight to warm your home. But when it's hot and dry, they flatten out to block the sun and keep things cool inside.

NEVER NEED AN EV CHARGING STATION AGAIN WITH THESE ROOFTOP SOLAR POWER PANELS

The Solar Gate system consists of a gridded array of pine-cone-scale-inspired self-bending elements housed between two panes of glass in an aluminum-frame window unit. Each element is ingeniously crafted with three distinct layers, each serving a unique purpose. The bottom layer is composed of a cellulose powder and a thermoplastic blend that swells when exposed to moisture. Above this lies a middle layer made of thermoplastic, which remains unaffected by moisture.

WHAT IS ARTIFICIAL INTELLIGENCE (AI)?

The top layer consists of flexible biocomposite filaments that serve to hold the entire structure together. When exposed to moist air, the bottom layer expands, causing the element to curl upwards. Conversely, in dry conditions, it returns to its flattened state. This simple yet effective mechanism allows the window to respond automatically to changing weather conditions, providing optimal shading and light penetration as needed.

SOLAR-POWERED BLIMP COULD BRING HIGH SPEED INTERNET TO YOUR AREA

The Solar Gate system underwent rigorous real-world testing to prove its effectiveness. In a comprehensive year-long study, researchers installed 424 Solar Gate elements in the south-facing skylight of a research building at the University of Freiburg. The results of this extensive trial were nothing short of impressive.

During the cool, wet winter months, the elements responded by curling upwards, allowing ample sunlight to penetrate the building. This natural response effectively warmed and illuminated the interior spaces, reducing the need for artificial heating and lighting. Conversely, as the seasons changed and brought warmer, drier summer conditions, the elements automatically flattened out.

This flattening action served to block excess sunlight, effectively keeping the building's interior cool and comfortable without the need for energy-intensive air conditioning. The test demonstrated the system's ability to autonomously adapt to changing weather conditions, providing optimal comfort and energy efficiency throughout the year.

5 BEST PORTABLE CHARGERS FOR ANY OCCASION 

This innovative approach to building technology has far-reaching implications beyond just window systems. Researchers have already begun exploring similar biomimetic principles in a variety of applications. For instance, studies have investigated the development of shading systems using wooden slats that can open and close in response to environmental conditions.

In the realm of textiles, scientists are working on "smart" clothing fabrics that can adapt to ambient temperature, providing optimal comfort for wearers. Perhaps most intriguingly, these principles are even being applied to the field of robotics, with researchers developing tiny mobile robots that can respond to environmental stimuli in ways inspired by natural mechanisms. As we continue to draw inspiration from nature's ingenious designs, the potential for creating more sustainable and responsive technologies seems boundless.

Nature never ceases to amaze us with its ingenious solutions, and the Solar Gate window system is a brilliant example of how we can harness these natural wonders. By mimicking the pinecone, scientists have created a game-changing technology that could revolutionize how we approach energy efficiency in our buildings. It's exciting to think about a future where our homes and offices adapt to the environment just like living organisms do.

NASA Radar Imagery Reveals Details About Los Angeles-Area Landslides

A topographic map of Rancho Palos Verdes, CA (Sept. 18–Oct. 17, 2024) shows landslide velocity in cm/week, with red areas moving fastest (≥10 cm/week). The slide extends beyond the 2007 boundary toward Abalone Cove. An arrow marks the landslide direction southward.
NASA’s UAVSAR airborne radar instrument captured data in fall 2024 showing the motion of landslides on the Palos Verdes Peninsula following record-breaking rainfall in Southern California in 2023 and another heavy-precipitation winter in 2024. Darker red indicates faster motion.
NASA Earth Observatory

Analysis of data from NASA radar aboard an airplane shows that the decades-old active landslide area on the Palos Verdes Peninsula has expanded.

Researchers at NASA’s Jet Propulsion Laboratory in Southern California used data from an airborne radar to measure the movement of the slow-moving landslides on the Palos Verdes Peninsula in Los Angeles County. The analysis determined that, during a four-week period in the fall of 2024, land in the residential area slid toward the ocean by as much as 4 inches (10 centimeters) per week.

Portions of the peninsula, which juts into the Pacific Ocean just south of the city of Los Angeles, are part of an ancient complex of landslides and has been moving for at least the past six decades, affecting hundreds of buildings in local communities. The motion accelerated, and the active area expanded following record-breaking rainfall in Southern California in 2023 and heavy precipitation in early 2024.

To create this visualization, the Advanced Rapid Imaging and Analysis (ARIA) team used data from four flights of NASA’s Uninhabited Aerial Vehicle Synthetic Aperture Radar (UAVSAR) that took place between Sept. 18 and Oct. 17. The UAVSAR instrument was mounted to a Gulfstream III jet flown out of NASA’s Armstrong Flight Research Center in Edwards, California, and the four flights were planned to estimate the speed and direction of the landslides in three dimensions.

In the image above, colors indicate how fast parts of the landslide complex were moving in late September and October, with the darkest reds indicating the highest speeds. The arrows represent the direction of horizontal motion. The white solid lines are the boundaries of the active landslide area as defined in 2007 by the California Geological Survey.

“In effect, we’re seeing that the footprint of land experiencing significant impacts has expanded, and the speed is more than enough to put human life and infrastructure at risk,” said Alexander Handwerger, the JPL landslide scientist who performed the analysis.

The insights from the UAVSAR flights were part of a package of analyses by the ARIA team that also used data from ESA’s (the European Space Agency’s) Copernicus Sentinel-1A/B satellites. The analyses were provided to California officials to support the state’s response to the landslides and made available to the public at NASA’s Disaster Mapping Portal.

Handwerger is also the principal investigator for NASA’s upcoming Landslide Climate Change Experiment, which will use airborne radar to study how extreme wet or dry precipitation patterns influence landslides. The investigation will include flights over coastal slopes spanning the California coastline.

NASA Scientists Find New Human-Caused Shifts in Global Water Cycle

In a recently published paper, NASA scientists use nearly 20 years of observations to show that the global water cycle is shifting in unprecedented ways. The majority of those shifts are driven by activities such as agriculture and could have impacts on ecosystems and water management, especially in certain regions.

“We established with data assimilation that human intervention in the global water cycle is more significant than we thought,” said Sujay Kumar, a research scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, and a co-author of the paper published in the Proceedings of the National Academy of Sciences.

The shifts have implications for people all over the world. Water management practices, such as designing infrastructure for floods or developing drought indicators for early warning systems, are often based on assumptions that the water cycle fluctuates only within a certain range, said Wanshu Nie, a research scientist at NASA Goddard and lead author of the paper.

“This may no longer hold true for some regions,” Nie said. “We hope that this research will serve as a guide map for improving how we assess water resources variability and plan for sustainable resource management, especially in areas where these changes are most significant.”

One example of the human impacts on the water cycle is in North China, which is experiencing an ongoing drought. But vegetation in many areas continues to thrive, partially because producers continue to irrigate their land by pumping more water from groundwater storage, Kumar said. Such interrelated human interventions often lead to complex effects on other water cycle variables, such as evapotranspiration and runoff.

Nie and her colleagues focused on three different kinds of shifts or changes in the cycle: first, a trend, such as a decrease in water in a groundwater reservoir; second, a shift in seasonality, like the typical growing season starting earlier in the year, or an earlier snowmelt; and third a change in extreme events, like “100-year floods” happening more frequently.

The scientists gathered remote sensing data from 2003 to 2020 from several different NASA satellite sources: the Global Precipitation Measurement mission satellite for precipitation data, a soil moisture dataset from the European Space Agency’s Climate Change Initiative, and the Gravity Recovery and Climate Experiment satellites for terrestrial water storage data. They also used products from the Moderate Resolution Imaging Spectroradiometer satellite instrument to provide information on vegetation health.

“This paper combines several years of our team’s effort in developing capabilities on satellite data analysis, allowing us to precisely simulate continental water fluxes and storages across the planet,” said Augusto Getirana, a research scientist at NASA Goddard and a co-author of the paper.

The study results suggest that Earth system models used to simulate the future global water cycle should evolve to integrate the ongoing effects of human activities. With more data and improved models, producers and water resource managers could understand and effectively plan for what the “new normal” of their local water situation looks like, Nie said.

Earth in Far-Ultraviolet

In this enhanced-color photo, Earth is represented in shades of aqua blue, red, and yellow. Earth's atmosphere is a bright blue haze, while the planet itself is red with a yellow outline on the sunlit side. Nearby stars are visible as blobs with similar colors to Earth.
NASA

On April 21, 1972, NASA astronaut John W. Young, commander of the Apollo 16 mission, took a far-ultraviolet photo of Earth with an ultraviolet camera. Young’s original black-and-white picture was printed on Agfacontour professional film three times, with each exposure recording only one light level. The three light levels were then colored blue (dimmest), green (next brightest), and red (brightest), resulting in the enhanced-color image seen here.

Dr. George Carruthers, a scientist at the Naval Research Laboratory, developed the ultraviolet camera – the first Moon-based observatory – for Apollo 16. Apollo 16 astronauts placed the observatory on the Moon in April 1972, where it sits today on the Moon’s Descartes highland region, in the shadow of the lunar module Orion.

Measurements from space support wildfire risk predictions

Researchers demonstrated that data from the International Space Station’s ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station (ECOSTRESS) instrument played a significant role in the ability of machine learning algorithms to predict wildfire susceptibility. This result could help support development of effective strategies for predicting, preventing, monitoring, and managing wildfires.

As the frequency and severity of wildfires increases worldwide, experts need reliable models of fire susceptibility to protect public safety and support natural resource planning and risk management. ECOSTRESS measures evapotranspiration, water use efficiency, and other plant-water dynamics on Earth. Researchers report that its water use efficiency data consistently emerged as the leading factor in predicting wildfires, with evaporative stress and topographic slope data also significant.

Combining instruments provides better emissions data

Scientists found that averaging data from the International Space Station’s OCO‐3 and EMIT external instruments can accurately measure the rate of carbon dioxide emissions from power plants. This work could improve emissions monitoring and help communities respond to climate change.

Carbon dioxide emissions from fossil fuel combustion make up nearly a third of human-caused emissions and are a major contributor to climate change. In many places, though, scientists do not know exactly how much carbon dioxide these sources emit. The Orbiting Carbon Observatory-3 or OCO-3 can quantify emissions over large areas and Earth Surface Mineral Dust Source Investigation data can help determine emissions from individual facilities. The researchers suggest future work continue to investigate the effect of wind conditions on measurements.

Thunderstorm phenomena observed from space

Observations by the International Space Station’s Atmosphere-Space Interactions Monitor (ASIM) instrument during a tropical cyclone in 2019 provide insight into the formation and nature of blue corona discharges often observed at the tops of thunderclouds. A better understanding of such processes in Earth’s upper atmosphere could improve atmospheric models and weather and climate predictions.

Scientists do not fully understand the conditions that lead to formation of blue corona discharges, bursts of electrical streamers, which are precursors to lightning. Observations from the ground are affected by scattering and absorption in the clouds. ASIM, a facility from ESA (European Space Agency), provides a unique opportunity for observing these high-atmosphere events from space.

Solar device transforms used tires to help purify water so that it's drinkable

Imagine a world where clean drinking water is readily available even in the most remote areas.

This vision is becoming a reality thanks to innovative research from scientists in Canada. 

A team of scientists at Dalhousie University in Halifax, Nova Scotia, has developed a groundbreaking device that could revolutionize water desalination, offering hope to millions facing water scarcity worldwide.

I’M GIVING AWAY THE LATEST & GREATEST AIRPODS PRO 2

At the heart of this innovation is a floating solar still, a device that harnesses the sun's energy to purify seawater. 

Dr. Mita Dasog, an associate professor of chemistry and Killam Memorial chair at Dalhousie, explains the science behind it: "Refractory plasmonic nanomaterials are very good at capturing light and converting that light into heat."

This principle forms the foundation of their ingenious design. The solar still, conceptualized by Dr. Matthew Margeson during his Ph.D. studies, addresses challenges that have long plagued similar devices. It minimizes thermal losses, prevents salt buildup and can withstand harsh maritime conditions.

A BREAKTHROUGH GADGET COULD HELP YOU DETECT MICROPLASTICS IN YOUR DRINKING WATER

The floating solar still operates through an elegantly simple yet highly effective process. First, ocean water is drawn up to the device's foam surface through a wicking system. Once the water reaches the surface, it is evaporated by solar-heated plasmonic materials. As the water vapor rises, the salt is left behind, ensuring that only purified water is collected. The vapor then recondenses on a clear plastic dome situated above the device. Finally, the purified water is funneled down the sides of the dome and collected in a sealed bag for easy access.

The results of this process are impressive. In real-world tests conducted in Halifax Harbour, the device produced up to 0.97 gallons of clean water daily, which was a record-breaking yield for passive floating solar stills.

WHAT IS ARTIFICIAL INTELLIGENCE (AI)?

AUTONOMOUS TRASH-GOBBLING ROBO BOAT WAGES WAR ON WATERWAY WASTE

What sets this device apart is its use of unconventional materials. Instead of relying on expensive precious metals, the team turned to an unlikely source: used tires. Through a process called pyrolysis, carbon waste from tires is transformed into a crucial component of the desalination unit.

Dr. Dasog emphasizes the importance of accessibility: "We shouldn't be making an expensive or very complicated device. It has to be easy to manufacture, last for a long time and be easy to take apart and move." This approach not only makes the technology more affordable but also addresses the environmental issue of tire waste.

THE SHAPE-SHIFTING UNDERWATER ROBOT PIONEERING THE DEPTHS OF THE SEA

The device's capabilities extend beyond water purification. It can simultaneously desalinate, disinfect and decontaminate water at a remarkably low cost: less than one cent per liter. It can also generate a small amount of thermoelectricity, potentially powering onboard water quality sensors.

SUBSCRIBE TO KURT’S YOUTUBE CHANNEL FOR QUICK VIDEO TIPS ON HOW TO WORK ALL OF YOUR TECH DEVICES

The team's next step is to conduct further testing in South Asia, with the ultimate goal of making the device available worldwide. Dasog, nominated for the Emerging Leader award at the Water Canada Summit, envisions the device as a lifeline for communities displaced by war or climate change.

As we tackle the growing challenges of water security, innovations like the plasmonic solar still shine a light of hope. By blending cutting-edge science with sustainable materials, the researchers at Dalhousie University are doing more than just purifying water; they’re paving the way for a future that is both equitable and resourceful. This device not only makes clean drinking water accessible but also highlights how we can use renewable energy sources to address pressing global issues.

How US-Indian NISAR Satellite Will Offer Unique Window on Earth

5 min read

Preparations for Next Moonwalk Simulations Underway (and Underwater)

artist’s concept depicts the NISAR satellite orbiting Earth over Antarctica
An equal collaboration between NASA and the Indian Space Research Organisation, NISAR will offer unprecedented insights into Earth’s constantly changing land and ice surfaces using synthetic aperture radar technology. The spacecraft, depicted here in an artist’s concept, will launch from India.
NASA/JPL-Caltech

A Q&A with the lead U.S. scientist of the mission, which will track changes in everything from wetlands to ice sheets to infrastructure damaged by natural disasters.

The upcoming U.S.-India NISAR (NASA-ISRO Synthetic Aperture Radar) mission will observe Earth like no mission before, offering insights about our planet’s ever-changing surface.

The NISAR mission is a first-of-a-kind dual-band radar satellite that will measure land deformation from earthquakes, landslides, and volcanoes, producing data for science and disaster response. It will track how much glaciers and ice sheets are advancing or retreating and it will monitor growth and loss of forests and wetlands for insights on the global carbon cycle.

As diverse as NISAR’s impact will be, the mission’s winding path to launch — in a few months’ time — has also been remarkable. Paul Rosen, NISAR’s project scientist at NASA’s Jet Propulsion Laboratory in Southern California, has been there at every step. He recently discussed the mission and what sets it apart.

Paul Rosen
NISAR Project Scientist Paul Rosen of NASA’s Jet Propulsion Laboratory first traveled to India in late 2011 to discuss collaboration with ISRO scientists on an Earth-observing radar mission. NASA and ISRO signed an agreement in 2014 to develop NISAR.
NASA/JPL-Caltech

How will NISAR improve our understanding of Earth?

The planet’s surfaces never stop changing — in some ways small and subtle, and in other ways monumental and sudden. With NISAR, we’ll measure that change roughly every week, with each pixel capturing an area about half the size of a tennis court. Taking imagery of nearly all Earth’s land and ice surfaces this frequently and at such a small scale — down to the centimeter — will help us put the pieces together into one coherent picture to create a story about the planet as a living system.

What sets NISAR apart from other Earth missions?

NISAR will be the first Earth-observing satellite with two kinds of radar — an L-band system with a 10-inch (25-centimeter) wavelength and an S-band system with a 4-inch (10-centimeter) wavelength.

Whether microwaves reflect or penetrate an object depends on their wavelength. Shorter wavelengths are more sensitive to smaller objects such as leaves and rough surfaces, whereas longer wavelengths are more reactive with larger structures like boulders and tree trunks.

So NISAR’s two radar signals will react differently to some features on Earth’s surface. By taking advantage of what each signal is or isn’t sensitive to, researchers can study a broader range of features than they could with either radar on its own, observing the same features with different wavelengths.

Is this new technology?

The concept of a spaceborne synthetic aperture radar, or SAR, studying Earth’s processes dates to the 1970s, when NASA launched Seasat. Though the mission lasted only a few months, it produced first-of-a-kind images that changed the remote-sensing landscape for decades to come.

It also drew me to JPL in 1981 as a college student: I spent two summers analyzing data from the mission. Seasat led to NASA’s Shuttle Imaging Radar program and later to the Shuttle Radar Topography Mission.

What will happen to the data from the mission?

Our data products will fit the needs of users across the mission’s science focus areas — ecosystems, cryosphere, and solid Earth — plus have many uses beyond basic research like soil-moisture and water resources monitoring.

We’ll make the data easily accessible. Given the volume of the data, NASA decided that it would be processed and stored in the cloud, where it’ll be free to access.

How did the ISRO partnership come about?

We proposed DESDynI (Deformation, Ecosystem Structure, and Dynamics of Ice), an L-band satellite, following the 2007 Decadal Survey by the National Academy of Sciences. At the time, ISRO was exploring launching an S-band satellite. The two science teams proposed a dual-band mission, and in 2014 NASA and ISRO agreed to partner on NISAR.

Since then, the agencies have been collaborating across more than 9,000 miles (14,500 kilometers) and 13 time zones. Hardware was built on different continents before being assembled in India to complete the satellite. It’s been a long journey — literally.

More About NISAR

The NISAR mission is an equal collaboration between NASA and ISRO and marks the first time the two agencies have cooperated on hardware development for an Earth-observing mission. Managed for the agency by Caltech, JPL leads the U.S. component of the project and is providing the mission’s L-band SAR. NASA is also providing the radar reflector antenna, the deployable boom, a high-rate communication subsystem for science data, GPS receivers, a solid-state recorder, and payload data subsystem.

Space Applications Centre Ahmedabad, ISRO’s lead center for payload development, is providing the mission’s S-band SAR instrument and is responsible for its calibration, data processing, and development of science algorithms to address the scientific goals of the mission. U R Rao Satellite Centre in Bengaluru, which leads the ISRO components of the mission, is providing the spacecraft bus. The launch vehicle is from ISRO’s Vikram Sarabhai Space Centre, launch services are through ISRO’s Satish Dhawan Space Centre, and satellite mission operations are by ISRO Telemetry Tracking and Command Network. National Remote Sensing Centre in Hyderabad is primarily responsible for S-band data reception, operational products generation, and dissemination.
