The Earth Observer Editor’s Corner: January–March 2025

NASA’s Earth Observing fleet continues to age gracefully. While several new missions have joined the fleet in the past year, scientists and engineers work to extend the life of existing missions and maximize their science along the way. The crowning example is the first Earth Observing System (EOS) Flagship mission, Terra, which celebrated a quarter-century in orbit on December 18, 2024.

Terra continues to collect daily morning Earth observations using five different instruments: Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER), Clouds and the Earth’s Radiant Energy System (CERES), Multi-angle Imaging SpectroRadiometer (MISR), Moderate Resolution Imaging Spectroradiometer (MODIS), and Measurement of Pollution in the Troposphere (MOPITT). Collectively, these observations have established a robust satellite record of global scientific processes to track changes in temperature, glaciers, clouds, vegetation, land-use, air quality, and natural hazards such as hurricanes, wildfires, and volcanic eruptions.

Originally designed for a six-year prime mission, Terra continues to deliver data used by emergency managers, researchers, and modelers over a quarter-of-a-century later. On December 18th, 2024, NASA celebrated the 25th anniversary of Terra’s launch with a celebration at the Goddard Space Flight Center (GSFC) Visitor’s Center. NASA Senior management [from Headquarters and GSFC] as well as other key figures from Terra’s long history gave brief remarks and perspectives on Terra’s development and achievements. To read a review of the celebration, see “Celebrating 25 Years of Terra.”

Terra-related sessions (poster and oral) during the Fall American Geophysical Union (AGU) meeting were well-attended. The Terra team took advantage of the meeting to have a celebratory anniversary dinner that included attendees representing each of the five instruments.

Another mission to recently reach a longevity milestone is NASA’s Orbiting Carbon Observatory-2 (OCO-2), which celebrated 10 years in space last summer. OCO-2, which launched on July 2, 2014, from the Vandenburg Air Force (now Space Force) Base in California, was originally designed as a pathfinder mission to measure carbon dioxide (CO2) with the precision and accuracy needed to quantify where, when, and how the Earth inhales and exhales this important greenhouse gas seasonally. OCO-2 was part of the international Afternoon Constellation, or “A-Train,” which also included Aqua, Aura, CloudSat, and CALIPSO, as well as international partner missions.

Since its launch, OCO-2 data have revealed unprecedented insights into how the carbon cycle operates – from observing the impact and recovery of tropical land and ocean ecosystems during El Niño events to revealing the outsized impacts of extreme events (e.g., floods, droughts, and fires) on ecosystem health and functioning. Researchers from around the world use OCO-2 data, opening new opportunities for understanding the response of the carbon cycle to human-driven perturbations, such as the impact of COVID lockdowns on atmospheric CO2 and improved quantification of emissions from large power plants and cities.

OCO-2 also maps vegetation fluorescence, which shows promise as a reliable early warning indicator of flash drought. During photosynthesis, plants “leak” unused photons, producing a faint glow known as solar-induced fluorescence (SIF). The stronger the fluorescence, the more CO2 a plant is taking from the atmosphere to power its growth. Ancillary SIF measurements from OCO-2 will help scientists better predict flash droughts, and understand how these impact carbon emissions.

Ten years into the mission, OCO-2 has become the gold standard for CO2 measurements from space. The spacecraft and instrument continue to perform nominally, producing data leading to new scientific discoveries.

OCO–3, built from spare parts during the build of OCO-2 and launched to the International Space Station (ISS) in 2019, also celebrated a milestone, marking five years in orbit on May 4, 2024. While the follow-on has the same instrument sensitivity and makes essentially the same measurements as OCO-2, the precessing vantage point on the ISS (as opposed to OCO-2’s polar orbit) and the use of a new pointing mirror assembly (PMA) results in significant day-to-day spatial and temporal sampling differences that allows CO2 tracking for diurnal variability. In addition, the flexible PMA system allows for a much more dynamic observation-mode schedule.

Further out in space, about 1 million mi (~1.1 million km) from Earth, orbiting the “L1” Lagrange point between Earth and Sun, the Deep Space Climate Observatory (DSCOVR) celebrated the 10th anniversary of its launch on February 11, 2025. The two NASA Earth observing instruments on DSCOVR are the Earth Polychromatic Camera (EPIC) and National Institute of Standards and Technology (NIST) Advanced Radiometer [NISTAR].

The 10th DSCOVR EPIC NISTAR Science Team Meeting was held October 16–18, 2024 at Goddard Space Flight Center. Former U.S. Vice President Al Gore opened the meeting with remarks that focused on remote sensing and the future of Earth observations. Following Gore’s remarks, DSCOVR mission leadership and representatives from GSFC and the National Oceanic and Atmospheric Administration (NOAA) gave presentations on DSCOVR operations, EPIC calibration, and NISTAR Status and Science.

The meeting provided an opportunity for participants to learn the status of DSCOVR’s Earth-observing instruments, the status of recently released Level-2 (geophysical) data products, and the resulting science. As more people use DSCOVR data worldwide, the science team hopes to hear from users and team members at its next meeting. The latest updates from the mission can be found on the EPIC website. For more details, see the Summary of the 10th DSCOVR EPIC and NISTAR Science Team Meeting.

Flying in the space between satellites and ground-based observations, NASA’s Airborne Science Program operates a fleet of aircraft, unpiloted aerial vehicles, and even kites to study Earth and space science. Since 1987, a highly modified McDonnell Douglas DC-8 aircraft has been a mainstay of ASP’s fleet ­­– see Photo 1. The aircraft, located at NASA’s Armstrong Flight Research Center (AFRC) in California, flew countless missions as a science laboratory, producing science data for the national and global scientific communities. NASA decided to retire the venerable DC-8 aircraft, which made its last science flight in April 2024. The DC-8 is being replaced with a similarly refurbished Boeing 777 aircraft, which will be even more capable than the DC-8 and is located at the NASA Langley Research Center (LaRC).

The NASA History Office and NASA Earth Science Division cohosted a workshop, titled “Contributions of the DC-8 to Earth System Science at NASA,” on October 24–25, 2024 at the Mary W. Jackson NASA Headquarters (HQ) Building in Washington, DC – for more details on the DC-8 event, see the article The NASA DC-8 Retires: Reflections on its Contributions to Earth System Science.

There are also updates from three recent NASA field campaigns – where ground observations are timed and coordinated with aircraft flights (often at more than one altitude) and with satellite overpasses to gain a comprehensive (i.e., multilayered, multiscale) picture of the atmosphere over a certain area. 

The Westcoast & Heartland Hyperspectral Microwave Sensor Intensive Experiment (WHyMSIE) campaign was held from October 17- November 18, 2024. Serving as a future NASA planetary boundary-layer (PBL) mission prototype, WHyMSIE aimed to capture a wide variety of thermodynamic, moisture, and PBL regimes across a variety of surface types. WHyMSIE was an initial step towards an integrated and affordable PBL observing system of systems, with multiple observing nodes – i.e., space, suborbital, and ground – from passive and active sensors to enable a comprehensive and coherent picture of essential PBL variables and hydrometeors that is not possible with any single sensor, observational approach, or scale. As a partnership between NASA and NOAA, this field campaign flew a first-of-its-kind hyperspectral microwave airborne measurements (CoSMIR-H) that was complemented by other passive (thermal emission, solar reflectance) and active (lidar, radar) sensors flying onboard the NASA ER-2 (AFRC) and G-III (LaRC), with coordination over a variety of ground-based sensor facilities.

The GSFC Lidar Observation and Validation Experiment (GLOVE) was conducted in February 2025 at Edwards Air Force Base, California – see Photo 2. GLOVE flew the Cloud Physics Lidar (CPL), Roscoe lidar, enhanced MODIS Airborne Simulator (eMAS) imaging scanner, and Cloud Radar System (CRS) on the ER-2 to validate NASA ICESat-2 atmospheric data products and validate ESA’s recently launched EarthCARE lidar, radar, and spectrometer products.

NASA’s Earth Science Division FireSense project focuses on delivering NASA’s unique Earth science and technological capabilities to operational agencies, striving to address challenges in US wildland fire management. Together with agency, academic, and private partners, FireSense completed an airborne campaign in a wildfire smoke-impacted airshed in Missoula, MT on August 27–29, 2024. During the three-day campaign, a NASA Uninhabited Aerial System (UAS) team conducted eight data-collection flights, partnering these launches with weather balloon launches.

FireSense uses airborne campaigns to evaluate capabilities and technologies to support decision making in wildland fire management and air quality forecasting. Targeted data collection produces better forecasts and more successful technology transfer to wildland fire operations. In the future, the FireSense Program will coordinate two airborne campaigns for spring 2025 at Geneva State Forest, Alabama and Kennedy Space Center located within Merritt Island National Wildlife Refuge, Florida. Both 2025 campaigns will incorporate data collection before, during, and after prescribed fire operations. Beyond NASA, the campaign works in close partnership with the U.S. Forest Service, National Weather Service, U.S. Fish and Wildlife Service, Department of Defense, as well as partners in academia and the private sector. For more information on FireSense’s most recent campaign in Montana see the Editor’s Corner supplemental summary of “The FireSense Project.”

Congratulations to Jack Kaye, Associate Director for research with the Earth Science Division within NASA’s Science Mission Directorate, who has received the William T. Pecora Award for his vision and creative leadership in multidisciplinary Earth science research, as well as spurring advancements in the investigator community, supporting development of sensors, and shaping NASA satellite and aircraft missions and research programs at the highest levels. To read more about this accomplishment, see “Kaye Honored with Pecora Award.

On the outreach front, AGU returned to Washington, DC, for its annual meeting from December 9–14, 2024. NASA continued to uphold its long-standing tradition as an AGU partner and exhibitor, leveraging the meeting as an opportunity to share the agency’s cutting-edge research, data, and technology with the largest collection of Earth and planetary science professionals in the world. Many of the estimated 25,000 students, scientists, and industry personnel who attended the conference visited the NASA Science exhibit, interacting with NASA subject matter experts and listening to Hyperwall presentations throughout the week.

As the final event in a busy calendar of annual scientific conferences, AGU is often an opportunity for NASA scientists to publish findings from the previous year and set goals for the year ahead. The agency’s robust portfolio of missions and programs will continue to set new records, such as NASA’s Parker Solar Probe pass of the Sun, and conduct fundamental research in Earth and space science. To read more about AGU 2024, see the article: AGU 2024: NASA Science on Display in the Nation’s Capital.

Bridging the Gap Between the Cosmic Microwave Background and the First Galaxies

Universe Today - Thu, 03/20/2025 - 2:18pm

One of the Holy Grails in cosmology is a look back at the earliest epochs of cosmic history. Unfortunately, the Universe's first few hundred thousand years are shrouded in an impenetrable fog. So far, nobody's been able to see past it to the Big Bang. As it turns out, astronomers are chipping away at that cosmic fog by using data from the Atacama Cosmology Telescope (ACT) in Chile.

Celebrating 25 Years of Terra

Expanded coverage of topics from “The Editor’s Corner” in The Earth Observer

Terra anniversary banner Image credit: NASA NASA personnel gather to celebrate Terra’s 25th anniversary at the Visitor Center at NASA’s Goddard Space Flight Center on December 18, 2024. Image credit: NASA

On December 18, 2024, Terra—the first EOS Flagship mission celebrated the 25th anniversary of its launch from Vandenberg Space Force (then Air Force) Base. Some 70 individuals gathered at the Goddard Space Flight Center’s (GSFC) Visitor Center to celebrate this remarkable achievement for the venerable mission – with 75 more participating virtually. 

The gathering began with a reception culminating with some informal remarks in the main area of the Visitor’s Center outside the auditorium from Marc Dinardo [Lockheed Martin, emeritus] who was involved in the design of Terra. He explained that – at the time it was being built in the 1990s – Terra represented a “big step forward” for Lockheed Martin compared to projects the company had done prior to this. He discussed several engineering feats, e.g., fitting spacecraft components into the Atlas rocket used to launch Terra, moving from tape recorders to solid state recorders for data storage, the (at the time) novel thermal system developed to reject heat and protect instruments, and the direct broadcast capabilities.

After the initial remarks, the in-person participants moved into the auditorium where they heard from representatives from NASA Senior management [both from Headquarters and GSFC] as well as from several key figures in Terra’s long history. Each speaker gave brief remarks and shared their perspectives on Terra’s development and achievements. Short summaries of each presentation follow below.

Julie Robinson [NASA HQ—Deputy Director of the Earth Science Division] began by noting that this feels like a family celebration.  She said her first  personal experience with Terra was submitting a proposal as a young scientist to do research that would use data from Terra. At that time the idea of studying Earth as a system of systems was brand new.  She had no idea at that time that more than a quarter-century later, she’d be involved  in planning the “next generation” Earth System Observatory (ESO). 

Shawn Domagal-Goldman [Deputy Director of the Sciences and Exploration Directorate] spoke about how some of the biggest science questions we try to answer are interdisciplinary and cross-instrument, spanning missions and generations. He said that the expertise and diverse skillsets of those who have worked on the Terra team over the past 25 years embodies this goal.

Tom Neumann [GSFC—Deputy Director of Earth Science Division (GSFC)] reflected on his early involvement in the Terra–Aqua–Aura proposal reviews. He noted the sheer number of people involved in the mission and the logistical challenges that organizing that size group presented at the time.  He also commented on the feeling of family surrounding the Team and how this surely contributed to its remarkable achievements over the past 25 years.

Guennadi Kroupnik [Canadian Space Agency—Director General of Space Utilization] extended congratulations to NASA and Terra team for 25 years of operations. He commented that this “six-year” mission has endured far beyond what was planned. Canada’s contribution was the Measurement of Pollution in the Troposphere (MOPITT) instrument with Jim Drummond [University of Toronto] as Principal Investigator. Kroupnik noted that MOPITT Is longest continuously running instrument in Canadian history. He is pleased that CSA has been able to partner with NASA on Terra and looks forward to future collaboration on the Atmospheric Observing System (AOS), which is one of the missions planned as part of ESO.

Jack Kaye [NASA Headquarters—Associate Director for Research of the Earth Science Division] spoke of Terra’s remarkable scientific accomplishments, the creativity of the team, and the intentional emphasis placed on validating the data, and the creativity of the Team. He also noted that the direct broadcast capability was extremely useful and led to many applications. Kaye remarked that the late Yoram Kauffman referred to the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) as the “zoom lens of Terra.”

Miguel Román [GSFC—Deputy Director for Atmospheres] described himself as a “child of Terra,” as he began his science career at around the same time that Terra launched and has been involved in various capacities ever since. Román recalled the launch taking place at Vandenberg, which is near vineyards, where the team celebrated the successful launch with local wine. He also remembered finally sharing a bottle of wine with the late Piers Sellers (who served as the first Terra project scientist) at one of the final gatherings Piers threw before he passed from cancer. Román also mentioned the Our Changing Planet book that four Earth Scientists – including former EOS Senior Project Scientist and Moderate Resolution Imaging Spectroradiometer (MODIS) Science Team Leader Michael King and former Aqua Project Scientist Claire Parkinson—both GSFC emeritus – collaborated to write that was published in 2007. This book made use of numerous images and data from Terra’s five instruments – as well as other EOS data.

Kurt Thome [GSFC—Terra Project Scientist] rounded out the presentations, emphasizing again what several have stated in their individual comments – the Terra Team truly is a family. He commented that he’s only been leading the mission for the past ten years and that his work builds on the shoulders of those who came before him. In particular, he acknowledged the slide Miguel Román showed briefly during his presentation that honored those who were part of the Terra family who have passed away – e.g., Piers Sellers, Yoram Kauffman.

How NASA’s “Autonomy Choreography” Will Impact Advanced Technologies

NASA - Breaking News - Thu, 03/20/2025 - 1:54pm

The Data & Reasoning Fabric technology could help these systems operate in harmony, supporting the astronauts and ground control on Earth.Credit: NASA

Imagine your car is in conversation with other traffic and road signals as you travel. Those conversations help your car anticipate actions you can’t see: the sudden slowing of a truck as it begins to turn ahead of you, or an obscured traffic signal turning red. Meanwhile, this system has plotted a course that will drive you toward a station to recharge or refuel, while a conversation with a weather service prepares your windshield wipers and brakes for the rain ahead.

This trip requires a lot of communication among systems from companies, government agencies, and organizations. How might these different entities – each with their own proprietary technology – share data safely in real time to make your trip safe, efficient, and enjoyable?

Technologists at NASA’s Ames Research Center in California’s Silicon Valley created a framework called Data & Reasoning Fabric (DRF), a set of software infrastructure, tools, protocols, governance, and policies that allow safe, secure data sharing and logical prediction-making across different operators and machines. Originally developed with a focus on providing autonomous aviation drones with decision-making capabilities, DRF is now being explored for other applications.

This means that one day, DRF-informed technology could allow your car to receive traffic data safely and securely from nearby stoplights and share data with other vehicles on the road. In this scenario, DRF is the choreographer of a complex dance of moving objects, ensuring each moves seamlessly in relation to one another towards a shared goal. The system is designed to create an integrated environment, combining data from systems that would otherwise be unable to interact with each other.

“DRF is built to be used behind the scenes,” said David Alfano, chief of the Intelligent Systems Division at Ames. “Companies are developing autonomous technology, but their systems aren’t designed to work with technology from competitors. The DRF technology bridges that gap, organizing these systems to work together in harmony.”

Traffic enhancements are just one use case for this innovative system. The technology could enhance how we use autonomy to support human needs on Earth, in the air, and even on the Moon.

Supporting Complex Logistics

To illustrate the technology’s impact, the DRF team worked with the city of Phoenix on an aviation solution to improve transportation of critical medical supplies from urban areas out to rural communities with limited access to these resources. An autonomous system identified where supplies were needed and directed a drone to pick up and transport supplies quickly and safely.

“All the pieces need to come together, which takes a lot of effort. The DRF technology provides a framework where suppliers, medical centers, and drone operators can work together efficiently,” said Moustafa Abdelbaky, senior computer scientist at Ames. “The goal isn’t to remove human involvement, but help humans achieve more.”

The DRF technology is part of a larger effort at Ames to develop concepts that enable autonomous operations while integrating them into the public and commercial sector to create safer, efficient environments.

“At NASA, we’re always learning something. There’s a silver lining when one project ends, you can identify a new lesson learned, a new application, or a new economic opportunity to continue and scale that work,” said Supreet Kaur, lead systems engineer at Ames. “And because we leverage all of the knowledge we’ve gained through these experiments, we are able to make future research more robust.”

Choreographed Autonomy

Industries like modern mining involve a variety of autonomous and advanced vehicles and machinery, but these systems face the challenge of communicating sufficiently to operate in the same area. The DRF technology’s “choreography” might help them work together, improving efficiency. Researchers met with a commercial mining company to learn what issues they struggle with when using autonomous equipment to identify where DRF might provide future solutions.

“If an autonomous drill is developed by one company, but the haul trucks are developed by another, those two machines are dancing to two different sets of music. Right now, they need to be kept apart manually for safety,” said Johnathan Stock, chief scientist for innovation at the Ames Intelligent Systems Division. “The DRF technology can harmonize their autonomous work so these mining companies can use autonomy across the board to create a safer, more effective enterprise.”

Further testing of DRF on equipment like those used in mines could be done at the NASA Ames Roverscape, a surface that includes obstacles such as slopes and rocks, where DRF’s choreography could be put to the test.

Stock also envisions DRF improving operations on the Moon. Autonomous vehicles could transport materials, drill, and excavate, while launch vehicles come and go. These operations will likely include systems from different companies or industries and could be choreographed by DRF.

As autonomous systems and technologies increase across markets, on Earth, in orbit, and on the Moon, DRF researchers are ready to step on the dance floor to make sure everything runs smoothly.

“When everyone’s dancing to the same tune, things run seamlessly, and more is possible.”

Hubble Sees a Spiral and a Star

NASA - Breaking News - Thu, 03/20/2025 - 1:48pm
This NASA/ESA Hubble Space Telescope Picture of the Week features a sparkling spiral galaxy paired with a prominent star, both in the constellation Virgo. While the galaxy and the star appear to be close to one another, even overlapping, they’re actually a great distance apart.ESA/Hubble & NASA, S. J. Smartt, C. Kilpatrick

This NASA/ESA Hubble Space Telescope image features a sparkling spiral galaxy paired with a prominent star, both in the constellation Virgo. While the galaxy and the star appear to be close to one another, even overlapping, they’re actually a great distance apart. The star, marked with four long diffraction spikes, is in our own galaxy. It’s just 7,109 light-years away from Earth. The galaxy, named NGC 4900, lies about 45 million light-years from Earth.

This image combines data from two of Hubble’s instruments: the Advanced Camera for Surveys, installed in 2002 and still in operation today, and the older Wide Field and Planetary Camera 2, which was in use from 1993 to 2009. The data used here were taken more than 20 years apart for two different observing programs — a real testament to Hubble’s long scientific lifetime!

Both programs aimed to understand the demise of massive stars. In one, researchers studied the sites of past supernovae, aiming to estimate the masses of the stars that exploded and investigate how supernovae interact with their surroundings. They selected NGC 4900 for the study because it hosted a supernova named SN 1999br.

In the other program, researchers laid the groundwork for studying future supernovae by collecting images of more than 150 nearby galaxies. When researchers detect a supernova in one of these galaxies, they can refer to these images, examining the star at the location of the supernova. Identifying a supernova progenitor star in pre-explosion images gives valuable information about how, when, and why supernovae occur.

The FireSense Project

Expanded coverage of topics from “The Editor’s Corner” in The Earth Observer

Wind is a major factor in fire. It controls how fires evolve and pose threats to the safety of communities. Traditionally data from weather balloons have been used to produce vertical soundings to define changes in atmospheric dynamics. However, their use is restricted during aircraft operations to combat active wildfires. New technologies are therefore needed to fill this critical measurement gap. The Uninhabited Aerial System (UAS) fits the bill, providing data that enables localized forecasting to help predict fire behavior.

The NASA Earth Science Division FireSense project, together with agency, academic, and private partners, completed an airborne campaign in a wildfire smoke-impacted airshed in Missoula, MT on August 27–29, 2024. During the three-day campaign, a NASA UAS team conducted eight data-collection flights– see Figure. They partnered these launches with weather balloon launches.

Using this real-time data, MITRE Corporation tested high-resolution “Score-based Data Assimilation” meteorological models and the National Oceanic and Atmospheric Administration (NOAA) High-Resolution Rapid Refresh (HRRR) operational atmospheric model against wind speed and temperature from local MesoNet weather stations. Environmental Systems Research Institute (ESRI) created comprehensive visualizations of flight paths, temperature, and wind.

The data collected during the Montana campaign were used to evaluate the impact of real-time data on model fire weather forecasts commonly used for operational decision making. The UAS sounding data were validated against weather ballon data. In addition, the campaign evaluated data validity from in-situ UAS soundings in a smoke impacted environment as well as assessed payload portability and user experience with the systems. The campaign served as a trial for interagency coordination between NOAA incident meteorologists and U.S. Forest Service (USFS) trained UAS pilots conducting data collection flights.

Pecora Award award for his vision and creative leadership in multidisciplinary Earth science research, as well as for spurring advancements in the investigator community, supporting development of sensors, and shaping NASA satellite and aircraft missions and research programs at the highest levels. 

As Associate Director for Research since 1999, Kaye is responsible for the research and data analysis programs for Earth System Science. He has contributed to national and international groups for decades, by serving as the NASA principal on the Subcommittee on Global Change Research in the U.S. Global Change Research Program and chairing the World Meteorological Organization Expert Team on Satellite Systems. Kaye has also served as a member of the Steering Committee for the Global Climate Observing System and on the National Research Council’s Roundtable on Science and Technology for Sustainability and the Chemical Sciences Roundtable. He also serves as NASA’s representative to the Subcommittee on Ocean Science and Technology. Kaye has devoted considerable energy toward developing early career researchers, stimulating the inclusion of a more diverse student population in science, technology, engineering, and mathematics. 

Kaye has received numerous NASA awards, including the Distinguished Service Medal in 2022 and the Meritorious Executive in the Senior Executive Service in 2004, 2010, and 2021. He was named a Fellow by the American Meteorological Society (AMS) in 2010 and by the American Association for the Advancement of Science (AAAS) in 2014. Kaye was also elected to serve as an office of the Atmospheric and Hydrospheric Science section of the AAAS (2015–2018).

Kaye received a Bachelor of Science degree from Adelphi University in 1976 and a Ph.D. from the California Institute of Technology in 1982. He held a post-doctoral research associateship at the U.S. Naval Research Laboratory. Kaye has published more than 50 refereed papers and contributed to numerous reports, books, and encyclopedias.

Kaye is joined in this honor this year by Chuanmin Hu [University of South Florida—Professor, Leader of Optical Oceanography Lab]. Hu received the Pecora Group award for his lab’s groundbreaking advancements in remote sensing and real-world applications, including the Sargassum Watch System.

The Pecora award is presented annually by the U.S. Geological Survey (USGS) and NASA, honors individuals and groups who have made outstanding contributions to the field of remote sensing – advancing Earth observation and benefiting society. The award is named after William T. Pecora, former Director of USGS and Under Secretary of the Interior. His early vision and support helped establish what we know today as the Landsat satellite program.
