              Preparations for Next Moonwalk Simulations Underway (and Underwater)

              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.

              ICESat-2 Applications Team Hosts Satellite Bathymetry Workshop

              Introduction

              On September 15, 2018, the NASA Ice, Cloud, and land Elevation Satellite-2 (ICESat-2) mission launched from Vandenberg Air Force Base and began its journey to provide spatially dense and fine-precision global measurements of Earth’s surface elevation. Now in Phase E of NASA’s project life cycle (where the mission is carried out, data is collected and analyzed, and the spacecraft is maintained) of the mission and with almost six years of data collection, the focus shifts to looking ahead to new applications and synergies that may be developed using data from ICESat-2’s one instrument: the Advanced Topographic Laster Altimetry System (ATLAS) – see Figure 1.

              Figure 1. The ATLAS instrument onboard the ICESat-2 platform obtains data using green, photon-counting lidar that is split into six beams. Figure credit: ICESat-2 mission team

              Satellite-derived bathymetry (SDB) is the process of mapping the seafloor using satellite imagery. The system uses light penetration and reflection in the water to make measurements and estimate variations in ocean floor depths. SDB provides several advantages over other bathymetry techniques (e.g., cost-effectiveness, global coverage, and faster data acquisition). On the other hand, SDB can be limited by water clarity, spatial resolution of the remote sensing measurement, and accuracy, depending on the method and satellite platform/instrument. These limitations notwithstanding, SDB can be used in a wide variety of applications (e.g., coastal zone management, navigation and safety, marine habitat monitoring, and disaster response). ICESat-2 has become a major contributor to SDB, with over 2000 journal article references to this topic to date. Now is the time to think about the state-of-the-art and additional capabilities of SDB for the future.

              To help stimulate such thinking, the NASA ICESat-2 applications team hosted a one-day workshop on March 17, 2025, which focused on the principles and methods for SDB. Held in conjunction with the annual US-Hydro meeting on March 17–20, 2025 at the Wilmington Convention Center in Wilmington, NC, the meeting was hosted by the Hydrographic Society of America. During the workshop the applications team brought together SDB end-users, algorithm developers, operators, and decision makers to discuss the current state and future needs of satellite bathymetry for the community. The objective of this workshop was to provide a space to foster collaboration and conceptualization of SDB applications not yet exploited and to allow for networking to foster synergies and collaborations between different sectors.

              Meeting Overview

              The workshop provided an opportunity for members from government, academia, and private sectors to share their SDB research, applications, and data fusion activities to support decision making and policy support across a wide range of activities. Presenters highlighted SDB principles, methods, and tools for SDB, an introduction of the new ICESat-2 bathymetric data product (ATL24), which is now available through the National Snow and Ice Data Center (NSIDC). During the workshop, the ICESat-2 team delivered a live demonstration of a web service for science data processing. Toward the end of the day, the applications team opened an opportunity for attendees to gather and discuss various topics related to SDB. This portion of the meeting was also available to online participation via Webex webinars, which broadened the discussion.

              Meeting Goal

              The workshop offered a set of plenary presentations and discussions. During the plenary talks, participants provided an overview of Earth observation and SDB principles, existing methods and tools, an introduction to the newest ICESat-2 bathymetry product ATL24, a demonstration of the use of the webservice SlideRule Earth, and opportunities for open discission, asking questions and developing collaborations.

              Meeting and Summary Format

              The agenda of the SDB workshop was intended to bring together SDB end-users, including ICESat-2 application developers, satellite operators, and decision makers from both government and non-governmental entities to discuss the current state and future needs of the community. This report is organized according to the workshop’s six session topics with a brief narrative summary of each presentation included. The discussions that followed were not recorded and are not included in the report. The last section of this report consists of conclusions and future steps. The online meeting agenda includes links to slide decks for many of the presentations.

              Welcoming Remarks

              Aimee Neeley [NASA’s Goddard Space Flight Center (GSFC)/Science Systems and Applications Inc. (SSAI)—ICESat-2 Mission Applications Lead] organized the workshop and served as the host for the event. She opened the day with a brief overview of workshop goals, logistics, and the agenda.

              Overview of Principles of SDB

              Ross Smith [TCartaSenior Geospatial Scientist] provided an overview of the principles of space-based bathymetry, including the concepts, capabilities, limitations, and methods. Smith began by relaying the history of satellite-derived bathymetry, which began with a collaboration between NASA and Jacques Cousteau in 1975, in which Cousteau used Landsat 1 data, as well as in situ data to calculate bathymetry to a depth of 22 m (72 ft) in the Bahama bank. Smith then described the five broad methodologies and concepts for deriving bathymetry from remote sensing: radar altimetry, bottom reflectance, wave kinematics, laser altimetry, and space-based photogrammetry – see Figure 2. He then introduced the broad methodologies, most commonly used satellite sensors, the capabilities and limitations of each sensor, and the role of ICESat-2 in satellite bathymetry.

              Review of SDB Methods and Tools

              In this grouping of plenary presentations, representatives from different organizations presented their methods and tools for creating satellite bathymetry products.

              Gretchen Imahori [National Oceanic and Atmospheric Administration’s (NOAA) National Geodetic Survey, Remote Sensing Division] presented the NOAA SatBathy (beta v2.2.3) Tool Update. During this presentation, Imahori provided an overview of the NOAA SatBathy desktop tool, example imagery, updates to the latest version of the tool, and the implementation plan for ATL24. The next session included more details about ATL24.

              Minsu Kim [United States Geological Survey (USGS), Earth Resource and Observation Center (EROS)/ Kellogg, Brown & Root (KBR)—Chief Scientist] presented the talk Satellite Derived Bathymetry (SDB) Using OLI/MSI Based-On Physics-Based Algorithm. He provided an overview of an SDB method based on atmospheric and oceanic optical properties. Kim also shared examples of imagery from the SDB product – see Figure 3.

              ICESat-2 Applications Team Hosts Satellite Bathymetry Workshop

              Introduction

              On September 15, 2018, the NASA Ice, Cloud, and land Elevation Satellite-2 (ICESat-2) mission launched from Vandenberg Air Force Base and began its journey to provide spatially dense and fine-precision global measurements of Earth’s surface elevation. Now in Phase E of NASA’s project life cycle (where the mission is carried out, data is collected and analyzed, and the spacecraft is maintained) of the mission and with almost six years of data collection, the focus shifts to looking ahead to new applications and synergies that may be developed using data from ICESat-2’s one instrument: the Advanced Topographic Laster Altimetry System (ATLAS) – see Figure 1.

              Figure 1. The ATLAS instrument onboard the ICESat-2 platform obtains data using green, photon-counting lidar that is split into six beams. Figure credit: ICESat-2 mission team

              Satellite-derived bathymetry (SDB) is the process of mapping the seafloor using satellite imagery. The system uses light penetration and reflection in the water to make measurements and estimate variations in ocean floor depths. SDB provides several advantages over other bathymetry techniques (e.g., cost-effectiveness, global coverage, and faster data acquisition). On the other hand, SDB can be limited by water clarity, spatial resolution of the remote sensing measurement, and accuracy, depending on the method and satellite platform/instrument. These limitations notwithstanding, SDB can be used in a wide variety of applications (e.g., coastal zone management, navigation and safety, marine habitat monitoring, and disaster response). ICESat-2 has become a major contributor to SDB, with over 2000 journal article references to this topic to date. Now is the time to think about the state-of-the-art and additional capabilities of SDB for the future.

              To help stimulate such thinking, the NASA ICESat-2 applications team hosted a one-day workshop on March 17, 2025, which focused on the principles and methods for SDB. Held in conjunction with the annual US-Hydro meeting on March 17–20, 2025 at the Wilmington Convention Center in Wilmington, NC, the meeting was hosted by the Hydrographic Society of America. During the workshop the applications team brought together SDB end-users, algorithm developers, operators, and decision makers to discuss the current state and future needs of satellite bathymetry for the community. The objective of this workshop was to provide a space to foster collaboration and conceptualization of SDB applications not yet exploited and to allow for networking to foster synergies and collaborations between different sectors.

              Meeting Overview

              The workshop provided an opportunity for members from government, academia, and private sectors to share their SDB research, applications, and data fusion activities to support decision making and policy support across a wide range of activities. Presenters highlighted SDB principles, methods, and tools for SDB, an introduction of the new ICESat-2 bathymetric data product (ATL24), which is now available through the National Snow and Ice Data Center (NSIDC). During the workshop, the ICESat-2 team delivered a live demonstration of a web service for science data processing. Toward the end of the day, the applications team opened an opportunity for attendees to gather and discuss various topics related to SDB. This portion of the meeting was also available to online participation via Webex webinars, which broadened the discussion.

              Meeting Goal

              The workshop offered a set of plenary presentations and discussions. During the plenary talks, participants provided an overview of Earth observation and SDB principles, existing methods and tools, an introduction to the newest ICESat-2 bathymetry product ATL24, a demonstration of the use of the webservice SlideRule Earth, and opportunities for open discission, asking questions and developing collaborations.

              Meeting and Summary Format

              The agenda of the SDB workshop was intended to bring together SDB end-users, including ICESat-2 application developers, satellite operators, and decision makers from both government and non-governmental entities to discuss the current state and future needs of the community. This report is organized according to the workshop’s six session topics with a brief narrative summary of each presentation included. The discussions that followed were not recorded and are not included in the report. The last section of this report consists of conclusions and future steps. The online meeting agenda includes links to slide decks for many of the presentations.

              Welcoming Remarks

              Aimee Neeley [NASA’s Goddard Space Flight Center (GSFC)/Science Systems and Applications Inc. (SSAI)—ICESat-2 Mission Applications Lead] organized the workshop and served as the host for the event. She opened the day with a brief overview of workshop goals, logistics, and the agenda.

              Overview of Principles of SDB

              Ross Smith [TCartaSenior Geospatial Scientist] provided an overview of the principles of space-based bathymetry, including the concepts, capabilities, limitations, and methods. Smith began by relaying the history of satellite-derived bathymetry, which began with a collaboration between NASA and Jacques Cousteau in 1975, in which Cousteau used Landsat 1 data, as well as in situ data to calculate bathymetry to a depth of 22 m (72 ft) in the Bahama bank. Smith then described the five broad methodologies and concepts for deriving bathymetry from remote sensing: radar altimetry, bottom reflectance, wave kinematics, laser altimetry, and space-based photogrammetry – see Figure 2. He then introduced the broad methodologies, most commonly used satellite sensors, the capabilities and limitations of each sensor, and the role of ICESat-2 in satellite bathymetry.

              NASA’s IXPE Obtains First X-ray Polarization Measurement of Magnetar Outburst

              NASA - Breaking News - Thu, 06/05/2025 - 12:00pm

              4 min read

              Preparations for Next Moonwalk Simulations Underway (and Underwater)

              What happens when the universe’s most magnetic object shines with the power of 1,000 Suns in a matter of seconds? Thanks to NASA’s IXPE (Imaging X-ray Polarimetry Explorer), a mission in collaboration with ASI (Italian Space Agency), scientists are one step closer to understanding this extreme event. 

              Magnetars are a type of young neutron star — a stellar remnant formed when a massive star reaches the end of its life and collapses in on itself, leaving behind a dense core roughly the mass of the Sun, but squashed down to the size of a city. Neutron stars display some of the most extreme physics in the observable universe and present unique opportunities to study conditions that would otherwise be impossible to replicate in a laboratory on Earth.

              Illustrated magnetar flyby sequence showing magnetic field lines. A magnetar is a type of isolated neutron star, the crushed, city-size remains of a star many times more massive than our Sun. Their magnetic fields can be 10 trillion times stronger than a refrigerator magnet's and up to a thousand times stronger than a typical neutron star's. This represents an enormous storehouse of energy that astronomers suspect powers magnetar outbursts.NASAs Goddard Space Flight Center/Chris Smith (USRA)

              The magnetar 1E 1841-045, located in the remnants of a supernova (SNR Kes 73) nearly 28,000 light-years from Earth, was observed to be in a state of outburst by NASA’s SwiftFermi, and NICER telescopes on August 21, 2024. 

              A few times a year, the IXPE team approves requests to interrupt the telescope’s scheduled observations to instead focus on unique and unexpected celestial events. When magnetar 1E 1841-045 entered this brighter, active state, scientists decided to redirect IXPE to obtain the first-ever polarization measurements of a flaring magnetar.

              Magnetars have magnetic fields several thousand times stronger than most neutron stars and host the strongest magnetic fields of any known object in the universe. Disturbances to their extreme magnetic fields can cause a magnetar to release up to a thousand times more X-ray energy than it normally would for several weeks. This enhanced state is called an outburst, but the mechanisms behind them are still not well understood. 

              Through IXPE’s X-ray polarization measurements, scientists may be able to get closer to uncovering the mysteries of these events. Polarization carries information about the orientation and alignment of the emitted X-ray light waves; the higher the degree of polarization, the more the X-ray waves are traveling in sync, akin to a tightly choreographed dance performance. Examining the polarization characteristics of magnetars reveals clues about the energetic processes producing the observed photons as well as the direction and geometry of the magnetar magnetic fields. 

              The IXPE results, aided by observations from NASA’s NuSTAR and NICER telescopes, show that the X-ray emissions from 1E 1841-045 become more polarized at higher energy levels while still maintaining the same direction of propagation. A significant contribution to this high polarization degree comes from the hard X-ray tail of 1E 1841-045, an energetic magnetospheric component dominating the highest photon energies observed by IXPE. “Hard X-rays” refer to X-rays with shorter wavelengths and higher energies than “soft X-rays.” Although prevalent in magnetars, the mechanics driving the production of these high energy X-ray photons are still largely unknown. Several theories have been proposed to explain this emission, but now the high polarization associated with these hard X-rays provide further clues into their origin.

              This illustration depicts IXPE’s measurements of X-ray polarization emitting from magnetar 1E 1841-045 located within the Supernova Remnant Kes 73. At the time of observation, the magnetar was in a state of outburst and emitting the luminosity equivalent to 1000 suns. By studying the X-ray polarization of magnetars experiencing an outburst scientists may be able to get closer to uncovering the mysteries of these events. Michela Rigoselli/Italian National Institute of Astrophysics

              The results are presented in two papers published in The Astrophysical Journal Letters, one led by Rachael Stewart, a PhD student at George Washington University, and the other by Michela Rigoselli of the Italian National Institute of Astrophysics.  The papers represent the collective effort of large international teams across several countries.

              “This unique observation will help advance the existing models aiming to explain magnetar hard X-ray emission by requiring them to account for this very high level of synchronization we see among these hard X-ray photons,” said Stewart. “This really showcases the power of polarization measurements in constraining physics in the extreme environments of magnetars.”

              Rigoselli, lead author of the companion paper, added, “It will be interesting to observe 1E 1841-045 once it has returned to its quiescent, baseline state to follow the evolution of its polarimetric properties.”

              IXPE is a space observatory built to discover the secrets of some of the most extreme objects in the universe. Launched in December 2021 from NASA’s Kennedy Space Center on a Falcon 9 rocket, the IXPE mission is part of NASA’s Small Explorer series. 

              IXPE, which continues to provide unprecedented data enabling groundbreaking discoveries about celestial objects across the universe, is a joint NASA and Italian Space Agency mission with partners and science collaborators in 12 countries. IXPE is led by NASA’s Marshall Space Flight Center in Huntsville, Alabama. BAE Systems, headquartered in Falls Church, Virginia, manages spacecraft operations together with the University of Colorado’s Laboratory for Atmospheric and Space Physics in Boulder.
