Summary of the 54th U.S.–Japan ASTER Science Team Meeting
Introduction
The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) Science Team (ST) organized a three-day workshop that took place June 9–11, 2025, at the Japan Space System’s (JSS) offices in Tokyo, Japan. About 25 people from Japan and the United States participated during the in-person meeting – see Photo 1.
U.S. participants included representatives of NASA/Jet Propulsion Laboratory (JPL); two universities – University of Arizona (UA) and University of Pittsburgh (UPitt); and Grace Consulting. Japanese participants represented JSS, the Geologic Survey of Japan (GSJ), National Institute of Advanced Industrial Science and Technology (AIST), National Institute for Environmental Studies (NIES), and the Remote Sensing Technology Center of Japan (RESTEC). Participants from Ibaraki University (IU), Nagoya University (NU), University of Tokyo (UT), and University of Tsukuba (Uts) also joined.

discuss impacts of the proposed NASA budget reductions for Fiscal Year (FY) 2026; respond to plans for future impacts on ASTER from possible power reductions on the Terra platform; receive updates on data acquisition status, data calibration and validation (cal/val) activities, data distribution plans, and applications using ASTER observations; and discuss the end-of-mission plans for Terra and ASTER and archive documentation requirements. The remainder of this article summarizes the highlights from the meeting, which includes an overview of the opening plenary session and summaries of the four working group sessions. A brief review of the closing plenary, which included summary reports from the chairpersons of all working groups, rounds out the report, followed by some overall concluding thoughts.
Opening Plenary Session
Yasushi Yamaguchi [NU—Japan ASTER ST Lead] and Michael “Mike” Abrams [JPL—U.S. ASTER ST Lead] welcomed participants and reviewed the agenda for the opening plenary and the schedule for the working group sessions.
Abrams presented highlights of science results based on ASTER data. He also discussed some issues that Woody Turner [NASA Headquarters—ASTER Program Scientist] had raised, including NASA’s response to the President’s proposed fiscal year (FY) 26 budget and the status of FY25 funding. Abrams reported that Terra passivation is currently scheduled for February 2027 and described Terra’s power status. [UPDATE: If the President’s proposed FY26 budget goes into effect without modification by Congress, the three Flagship missions will enter accelerated Phase F (closeout); Terra passivation would start in November 2025 and be complete by March 2026.]
Abrams reviewed the status of the Terra spacecraft, showing slides provided by Jason Hendrickson [GSFC]. The Flight Operations Team staffing remains constant. Science data capture for ASTER remains above 99%. The impact of the shunt failure on November 28, 2024 required the safe halting of the instrument. Visible-near-infrared (VNIR) observations resumed in mid-January, and thermal infrared (TIR) observations resumed in mid-May. Collision avoidance events continue to be part of normal operations.
Hitomi Inada [JSS] provided a status report on the ASTER instrument. Many of the monitored components (i.e., VNIR pointing motor) are beyond their original useful life in orbit, but the aging hardware shows no signs of wearing out or a decrease in performance. She showed data that indicated that the temperature and current telemetry trends remain stable.
Abrams presented ASTER product distribution statistics provided by Cole Krehbiel [Land Processes Distributed Active Archiver Center (LP DAAC]). The ASTER Digital Elevation Model continues to be the most ordered product among all users of ASTER data. As defined by the ST at the last meeting, most ASTER data products [e.g., Version 4 (V4) products] are being created and placed in a searchable/orderable archive that can be accessed through NASA’s Earthdata tool. Abrams reported that the LP DAAC started producing these files in January 2025 and will be finished before August 2026.
Koki Iwao [GSJ] presented AIST’s product distribution statistics. Over 4.7 million scenes have been acquired and processed to Level 1A (L1A) since June 10, 2025. AIST continues to distribute ASTER’s pseudo-natural color scenes in keyhole mark-up language (KML – a file format used to display geographic data) and scene-based Digital Elevation Models. The largest number of users of Japanese products are from the United States.
Tetsushi Tachikawa [JSS] summarized the status of ASTER observations since the beginning of the mission. He reported that all of the global observation programs are functioning normally, acquiring data as planned. Updates to the observation programs will be considered by this week’s working groups. Tachikawa also added that the change of the orbit repeat – after Terra’s October 2022 exit from the Morning Constellation – has been accommodated in the ASTER scheduler.
Abrams presented a report on behalf of Simon Hook [JPL], who was unable to attend the meeting. Hook’s information provides a status update for the multispectral TIR instrument on NASA’s ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station (ECOSTRESS) mission. Abrams also spoke about NASA’s future Surface Biology and Geology (SBG) mission, which is part of the planned Earth System Observatory.
Applications Working Group
The applications session provided a sampling of how ASTER data are used. A few examples are highlighted below. The second half of the session was devoted to a discussion of end-of-mission documentation requirements. This included a review of the NASA guiding document and sharing of existing documents.
Michael Ramsey [UPitt] presented work on forecasting volcanic activity with the ASTER long-term archive. His team developed a statistical detection code to extract accurate temperature anomalies for five test volcanoes over 25 years. They used these results to train a deep learning approach for anomaly detection in future TIR data. The method showed 73% success for Piton del la Fournaise volcano, Réunion island, and near 100% success for Sheveluch volcano, Kamchatka Krai, Russia.
Miyuki Muto [IU] reported on waste volume changes in 15 open landfills in developing countries using more than 20 years of ASTER time-series digital surface models – see Figure 1. The method was found to be consistent with reports using synthetic aperture radar (SAR) data, which dates to 2016. Thus, ASTER can provide a longer time series for future optical or radar studies.

Figure credit: Figure taken from Muto and Tonooka (2025), Sensors Mike Abrams presented the 25-year history of ASTER data applied to geologic mapping and mineral exploration. He explained how the first published papers appeared a few years after launch and validated the unique mineralogical information contained in the ASTER data. Over the following 20 years, several reports from mineral exploration companies announced the discovery of gold, chromite, and lithium deposits, which were found largely based on analysis of ASTER data.
Calibration/Validation Working Group
The Calibration/Validation (cal/val) working group is responsible for monitoring the radiometric and geometric performance of ASTER’s VNIR and TIR instruments. Three different cal/val techniques are used including: analysis of onboard calibration lamps, comparison with onboard blackbodies, and measurements of pseudo-invariant ground targets during field campaigns. The L2 software algorithms are being updated for the final, archival processing which is anticipated to be completed in May 2026.
Bjorn Eng [JPL] reported that the newest version of the L2 algorithm for ASTER VNIR and TIR cal/val was delivered to the LPDAAC for ingest and testing. Eng explained how the new software includes Modern-Era Retrospective Analysis for Research and Applications, Version 2 (MERRA-2) data, which allows users to create atmospheric profiles for temperature, pressure, water vapor, and ozone. MERRA-2 is an improvement – both spatially and temporally – over the National Centers for Environmental Prediction’s Global Data Assimilation System that is used in the original MERRA. The new L2 production algorithms were validated, and the LP DAAC began incorporating the algorithms into the static archive in January 2025.
Mike Abrams presented on behalf of Cole Krehbiel [LP DAAC] and reported on the assessment of geometric performance of the L1 processing software, which was updated to the new Landsat ground control point library. He also presented an improved global digital elevation model. The ASTER final processing campaign uses the improved control point library.
Satoru Yamamoto [GSJ] presented updates to the calibration trends of the onboard VNIR lamps. Two onboard calibrations were performed on September 20, 2024 and November 8, 2024. Several analyses of the calibration lamps showed no significant change in the data trends – see Figure 2. The signal-to-noise ratios are still greater than the requirement of 140.

Figure credit: Satoru Yamamoto Soushi Kato [RESTEC] presented results from his September 2024 field campaign in Nevada and Utah. The campaign was marked by clear weather during ASTER’s day and night overpasses. Kato compared his in situ TIR measurements with the standard ASTER temperature products from the LP DAAC. The agreement for the five AESTER TIR bands was within ± 1.5 K.
Hideyuki Tonooka [IU] presented the results of his TIR field calibration campaigns at the same time and location as those conducted by Kato (described in previous presentation summary). Additionally, he reported that several calibration campaigns conducted at Lake Kasumigaura, Japan were cancelled due to cloudy weather, which led to the suspension of ASTER data acquisition. Tonooka compared his in situ TIR measurements with the standard ASTER temperature products from the LP DAAC. The agreement for the five ASTER TIR bands was within ± 1.3 K, except for band 10 at the Utah site where the discrepancy was -2.3 K.
Temperature–Emissivity Working Group
This group focuses on ASTER’s kinetic temperature and emissivity products, as well as application of these products and review of the nighttime TIR global mapping program status.
Mike Abrams presented his analyses of the ASTER Level-2 Surface Kinetic Temperature Product (AST_08) for a nighttime scene acquired over Lake Tahoe, CA. He compared the on-demand MERRA-2 product from NASA’s Global Modeling and Assimilation Office with the archive-produced product. The comparison showed that the two products were identical, pixel-by-pixel. Abrams conducted a second analysis to compare the archived MERRA_2 AST_08 product with the on-demand Moderate Resolution Imaging Spectroradiometer (MODIS) AST-08 product to assess the difference in temperature due to improved MERRA-2 atmospheric parameters. The MERRA-2 product had lower temperature values for higher elevations and higher values for lower elevations with more column water vapor – see Figure 3. This result is physically correct and validates the improvement using MERRA-2 atmospheric data.
Figure 3. Colorized difference by temperature, in Kelvin, between the product using MERRA-2 and MODIS atmospheric values: blue -1.0 to -0.6; green -0.5 to -0.1; red 0.0; and yellow 0.1 to 0.5. Figure credit: Michael Abrams Hideyuki Tonooka discussed the status of installation of the JPL radiometer at Lake Kasumigaura. The plan is to mount the radiometer on an existing observation in the middle of the lake. The radiometer will be operated jointly by JPL and IU. The installation is planned to start in the Summer 2025.
Tetsuchi Tachikawa reviewed the status of the current Thermal Global Mapping acquisition program to acquire cloud-free TIR nighttime images over most of the Earth’s land surface. He explained that the program is refreshed every year, with most recent refresh beginning May 2025.
Operations and Mission Planning Working Group
The Operations and Mission Planning Working Group oversees and reviews the acquisition programs executed by the ASTER scheduler. Because ASTER data acquisitions have to be scheduled every day to accommodate ASTER’s average 8% duty cycle, ST members developed an automatic program to select 600–700 daily scenes from the possible 3000 plus images uploaded in the request archive.
Tachikawa reviewed the status of acquisition scheduling. Urgent observations receive the highest priority and can be scheduled close to acquisition time. Approximately 70 scenes are programmed per month – with over 95% acquisition success. By contrast, global mapping data acquisitions receive the lowest priority and are used to fill in the scenes for the daily quota. He explained that the goal of the ASTER is to have the instrument acquire at least one cloud-free image for every place on Earth. Due to persistent cloud cover, success is typically ~85% after several years, at which time the program is restarted. Tachikawa next gave short updates on three other acquisition programs that focus on islands, volcanoes, glaciers, and cloudy areas, respectively. The global volcano image acquisition program will continue with no change to the observation parameters. Acquisition of images of islands and over cloudy areas will also continue in current form. The global glacier acquisition program will be modified to change the VNIR gain settings to optimize images over snow and ice.
Tachikawa also discussed the effect of the ASTER shutdown in November 2024 and cessation of all ASTER data acquisitions. VNIR-only acquisitions were resumed in January 2025, and TIR acquisitions resumed in May 2025, with full operations and acquisitions of data from both VNIR and TIR instruments.
Closing Plenary Session
Each chairperson summarized the presentations, discussions, and recommendations that occurred during their respective working group session. The overall consensus maintained that the ASTER instrument is operating normally again – with no indications of any component failures. The ST is preparing to absorb the impact of the 50% budget reduction on the Flight Operation Team at GSFC. At this time, the main impact has been a small increase in lost data (1–2%) as a result of the absence of operators to attempt immediate recovery. The ST also approved plans for ASTER’s contribution to the Terra power mitigation plan, and the recommendation has been forwarded to the Terra Project Scientist and the Flight Operations Team.
Conclusion
The 54th ASTER ST Meeting successfully covered all critical issues introduced during the Opening Plenary Session. The ST worked on formulating priorities for reduction of ASTER instrument operations in response to possible future Terra power reductions. During working group sessions, participants received updates on a variety of topics (e.g., instrument scheduling, instrument performance, archiving plans, and new applications). Although this may be the last Joint U.S./Japan ASTER ST Meeting, the 55th joint meeting was tentatively scheduled for May 2026.

NASA’s 1991 Discovery shuttle video shows UFOs making impossible maneuvers, evading a possible Star Wars railgun test. Evidence of secret tech?
In September 1991, NASA’s Space Shuttle Discovery transmitted live video that has since become one of the most debated UFO clips ever recorded. The footage, later analyzed by independent researchers, shows glowing objects in orbit performing maneuvers far beyond the limits of known physics.
One object appears over Earth’s horizon, drifts smoothly, then suddenly reacts to a flash of light by accelerating at impossible speeds, estimated at over 200,000 mph while withstanding forces of 14,000 g’s. NASA officially dismissed the anomalies as ice particles or debris, but side by side comparisons with actual orbital ice show key differences: the objects make sharp turns, sudden accelerations, and fade in brightness in ways consistent with being hundreds of miles away, not near the shuttle.
Image analysis expert Dr. Mark Carlotto confirmed that at least one object was located about 1,700 miles from the shuttle, placing it in Earth’s atmosphere. At that distance, the object would be too large and too fast to be dismissed as ice or space junk.
The flash and two streaks seen in the video resemble the Pentagon’s “Brilliant Pebbles” concept, a railgun based missile defense system tested in the early 1990s. Researchers suggest the shuttle cameras may have accidentally, or deliberately, captured a live Star Wars weapons test in orbit.
The UFO easily evaded the attack, leading some to conclude that it was powered by a form of hyperdimensional technology capable of altering gravity.
Notably, following this 1991 incident, all subsequent NASA shuttle external camera feeds were censored or delayed, raising speculation that someone inside the agency allowed the extraordinary footage to slip out.

This photo was taken by astronauts aboard the International Space Station during Expedition 44. Credit: NASA astronauts on board Expedition 44 Did you see that gorgeous photo NASA astronaut Nichole Ayers took on July 3, 2025? Originally thought to be a sprite, Ayers confirmed catching an even rarer form of a Transient Luminous Events (TLEs) — a gigantic jet.
“Nichole Ayers caught a rare and spectacular form of a TLE from the International Space Station — a gigantic jet,” said Dr. Burcu Kosar, Principal Investigator of the Spritacular project.
Gigantic jets are a powerful type of electrical discharge that extends from the top of a thunderstorm into the upper atmosphere. They are typically observed by chance — often spotted by airline passengers or captured unintentionally by ground-based cameras aimed at other phenomena. Gigantic jets appear when the turbulent conditions at towering thunderstorm tops allow for lightning to escape the thunderstorm, propagating upwards toward space. They create an electrical bridge between the tops of the clouds (~20 km) and the upper atmosphere (~100 km), depositing a significant amount of electrical charge.
Sprites, on the other hand, are one of the most commonly observed types of TLEs — brief, colorful flashes of light that occur high above thunderstorms in the mesosphere, around 50 miles (80 kilometers) above Earth’s surface. Unlike gigantic jets, which burst upward directly from thundercloud tops, sprites form independently, much higher in the atmosphere, following powerful lightning strikes. They usually appear as a reddish glow with intricate shapes resembling jellyfish, columns, or carrots and can span tens of kilometers across. Sprites may also be accompanied or preceded by other TLEs, such as Halos and ELVEs (Emissions of Light and Very Low Frequency perturbations due to Electromagnetic Pulse Sources), making them part of a larger and visually spectacular suite of high-altitude electrical activity. The world of Transient Luminous Events is a hidden zoo of atmospheric activity playing out above the storms. Have you captured an image of a jet, sprite, or other type of TLE?

NASA’s Nancy Grace Roman Space Telescope will be a discovery machine, thanks to its wide field of view and resulting torrent of data. Scheduled to launch no later than May 2027, with the team working toward launch as early as fall 2026, its near-infrared Wide Field Instrument will capture an area 200 times larger than the Hubble Space Telescope’s infrared camera, and with the same image sharpness and sensitivity. Roman will devote about 75% of its science observing time over its five-year primary mission to conducting three core community surveys that were defined collaboratively by the scientific community. One of those surveys will scour the skies for things that pop, flash, and otherwise change, like exploding stars and colliding neutron stars.
These two images, taken one year apart by NASA’s Hubble Space Telescope, show how the supernova designated SN 2018gv faded over time. The High-Latitude Time-Domain Survey by NASA’s Nancy Grace Roman Space Telescope will spot thousands of supernovae, including a specific type that can be used to measure the expansion history of the universe.Credit: NASA, ESA, Martin Kornmesser (ESA), Mahdi Zamani (ESA/Hubble), Adam G. Riess (STScI, JHU), SH0ES Team Called the High-Latitude Time-Domain Survey, this program will peer outside of the plane of our Milky Way galaxy (i.e., high galactic latitudes) to study objects that change over time. The survey’s main goal is to detect tens of thousands of a particular type of exploding star known as type Ia supernovae. These supernovae can be used to study how the universe has expanded over time.
“Roman is designed to find tens of thousands of type Ia supernovae out to greater distances than ever before,” said Masao Sako of the University of Pennsylvania, who served as co-chair of the committee that defined the High-Latitude Time-Domain Survey. “Using them, we can measure the expansion history of the universe, which depends on the amount of dark matter and dark energy. Ultimately, we hope to understand more about the nature of dark energy.”
Probing Dark Energy
Type Ia supernovae are useful as cosmological probes because astronomers know their intrinsic luminosity, or how bright they inherently are, at their peak. By comparing this with their observed brightness, scientists can determine how far away they are. Roman will also be able to measure how quickly they appear to be moving away from us. By tracking how fast they’re receding at different distances, scientists will trace cosmic expansion over time.
Only Roman will be able to find the faintest and most distant supernovae that illuminate early cosmic epochs. It will complement ground-based telescopes like the Vera C. Rubin Observatory in Chile, which are limited by absorption from Earth’s atmosphere, among other effects. Rubin’s greatest strength will be in finding supernovae that happened within the past 5 billion years. Roman will expand that collection to much earlier times in the universe’s history, about 3 billion years after the big bang, or as much as 11 billion years in the past. This would more than double the measured timeline of the universe’s expansion history.
Recently, the Dark Energy Survey found hints that dark energy may be weakening over time, rather than being a constant force of expansion. Roman’s investigations will be critical for testing this possibility.
Seeking Exotic Phenomena
To detect transient objects, whose brightness changes over time, Roman must revisit the same fields at regular intervals. The High-Latitude Time-Domain Survey will devote a total of 180 days of observing time to these observations spread over a five-year period. Most will occur over a span of two years in the middle of the mission, revisiting the same fields once every five days, with an additional 15 days of observations early in the mission to establish a baseline.
This infographic describes the High-Latitude Time-Domain Survey that will be conducted by NASA’s Nancy Grace Roman Space Telescope. The survey’s main component will cover over 18 square degrees — a region of sky as large as 90 full moons — and see supernovae that occurred up to about 8 billion years ago.Credit: NASA’s Goddard Space Flight Center “To find things that change, we use a technique called image subtraction,” Sako said. “You take an image, and you subtract out an image of the same piece of sky that was taken much earlier — as early as possible in the mission. So you remove everything that’s static, and you’re left with things that are new.”
The survey will also include an extended component that will revisit some of the observing fields approximately every 120 days to look for objects that change over long timescales. This will help to detect the most distant transients that existed as long ago as one billion years after the big bang. Those objects vary more slowly due to time dilation caused by the universe’s expansion.
“You really benefit from taking observations over the entire five-year duration of the mission,” said Brad Cenko of NASA’s Goddard Space Flight Center in Greenbelt, Maryland, the other co-chair of the survey committee. “It allows you to capture these very rare, very distant events that are really hard to get at any other way but that tell us a lot about the conditions in the early universe.”
This extended component will collect data on some of the most energetic and longest-lasting transients, such as tidal disruption events — when a supermassive black hole shreds a star — or predicted but as-yet unseen events known as pair-instability supernovae, where a massive star explodes without leaving behind a neutron star or black hole.

The High-Latitude Time-Domain Survey will be split into two imaging “tiers” — a wide tier that covers more area and a deep tier that will focus on a smaller area for a longer time to detect fainter objects. The wide tier, totaling a bit more than 18 square degrees, will target objects within the past 7 billion years, or half the universe’s history. The deep tier, covering an area of 6.5 square degrees, will reach fainter objects that existed as much as 10 billion years ago. The observations will take place in two areas, one in the northern sky and one in the southern sky. There will also be a spectroscopic component to this survey, which will be limited to the southern sky.
“We have a partnership with the ground-based Subaru Observatory, which will do spectroscopic follow-up of the northern sky, while Roman will do spectroscopy in the southern sky. With spectroscopy, we can confidently tell what type of supernovae we’re seeing,” said Cenko.
Together with Roman’s other two core community surveys, the High-Latitude Wide-Area Survey and the Galactic Bulge Time-Domain Survey, the High-Latitude Time-Domain Survey will help map the universe with a clarity and to a depth never achieved before.

For three days, military aircraft circled the quiet Welsh village of Pentyrch, as if anticipating something extraordinary. Then, on Friday, February 26, 2016 at exactly 2:30 AM, their patience was rewarded as a colossal black/glowing pyramid-shaped object suddenly materialized in the sky above the village.
What followed was a four-minute battle between military forces and unknown objects that left witnesses paralyzed and the government scrambling to cover their tracks.
Caz Clarke watched the entire encounter unfold from her backyard. She witnessed something “absolutely out of this world.”
She recalled being drawn outside in the early morning hours by an overwhelming light illuminating the fields behind her home. Above her loomed a massive pyramid-shaped object glowing in the night sky.
Clarke described how the UFO appeared to “scan” her before releasing two smaller objects, one red, one green, that split off in opposite directions.
For eight years, she fought the Ministry of Defense to uncover the truth. Her investigation revealed illegal operations, falsified documents, and a coordinated cover-up that reached the highest levels of government.
The evidence suggests our military has protocols for hunting UFOs and procedures for retrieval operations. This wasn’t an isolated event — it was part of an ongoing, hidden agenda.
