Introduction

The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) Science Team (ST) organized a three-day workshop that took place September 11–13, 2023, at the offices of Japan Space Systems (JSS) in Tokyo. Over 40 people from Japan and the U.S. participated in the in-person meeting—some of whom are shown in the Photo below. U.S. participants included members from NASA/Jet Propulsion Laboratory (JPL), NASA’s Land Processes Distributed Active Archive Center (LPDAAC), NASA’s Goddard Space Flight Center (GSFC), University of Arizona (UA), Grace Consulting (GC), and University of Pittsburgh (Pitt). Japanese members included representatives from JSS, Ibaraki University (IU), Nagoya University (NU), University of Tokyo (UT), Geologic Survey of Japan (GSJ), National Institute of Advanced Industrial Science and Technology (AIST), University of Tsukuba (UTs), and Remote Sensing Technology Center of Japan (RESTEC). 

The meeting objectives focused on discussing impacts of the 50% budget reductions to the Terra mission (including ASTER) that have been proposed in the NASA Budget for Fiscal Years (FY) 2024–26; revised spacecraft management protocols by the Flight Operations Team; data acquisition status; data calibration and validation; data distribution; status of Level-1 processing interruption; applications; and end-of-mission plans. After summarizing the opening plenary presentations, the remainder of this article provides highlights from meetings of the various ASTER working groups and the closing plenary session.

Opening Plenary Session

Yasushi Yamaguchi [NU] and Michael Abrams [JPL—ASTER ST Leaders from Japan and the U.S., respectively] welcomed participants and reviewed the agenda for the opening plenary and the schedule for the week’s working groups.

Akira Tsuneto [AIST—Vice President], whose office is responsible for the ASTER project, presented a special welcome. As the former Director of Space Industry Office in the Japan Ministry of Economy, Trade and Industry (METI), he was responsible for making ASTER data free to all users.

Michael Abrams [JPL] presented Jason Hendrickson’s [GSFC] slides on the operations status of NASA’s Terra platform—which has changed significantly since the last meeting. The Earth Science Mission Operations (ESMO) Flight Operations Team began implementing “Lights Out Operation,” reducing staff from 24/7 coverage and eliminating the night shift. These changes resulted in a small increase in data gaps and delayed anomaly response. In early 2023 Terra lost two of its 24 solar array shunts. Full power capability remains—however, there is only one spare shunt remaining. Those issues notwithstanding, Terra remains healthy after more than 23 years of operation. 

Chris Torbert [LPDAAC] presented ASTER product distribution statistics. The ASTER Global Digital Elevation Model (DEM) continues to be the most ordered product. Torbert discussed the ASTER Preservation Content Specification for the end-of-mission archiving. There is a NASA document that describes the desired content of this archive. As described by the ST at the last meeting, most ASTER data products will be created as real files and placed in a searchable and orderable archive, accessed through NASA’s Earthdata tool, where mission preservation documents for other instruments (e.g., HIRDLS, ICESat/GLAS, TOMS) can be found.

Michael Abrams [JPL] presented highlights of science results based on ASTER data—including the 2023 Earth Science Senior Review. Terra presented its report to NASA Headquarters, but as of this meeting, the response is still pending. However, as stated earlier, a three-year budget reduction of 50% is anticipated.

Hitomi Inada [JSS] presented the status of the ASTER instrument. Although many of the monitored components [e.g., visible-near-infrared (VNIR) pointing motor] have exceeded their original useful life in orbit, they show no signs of decreases in performance. All temperature and current telemetry trends remain straight lines.

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. The change of the orbit repeat after the October 2022 constellation exit maneuver has been accommodated in the ASTER scheduler.

Simon Hook [JPL] described the status of the multispectral thermal infrared (TIR) instrument on the ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station (ECOSTRESS) as well as NASA’s future Surface Biology and Geology (SBG) mission, which is part of the planned Earth System Observatory.

Applications Working Group

The applications session offered a sample of the variety of applications that make use of data from ASTER, see examples below. Miyuki Muto [IU] shared her work to estimate the volume of waste in 19 landfills in 11 countries through analysis of ASTER DEM data over the past 20 years. Analysis of data from a site in India showed that the volume of waste increased four-fold over 20 years—see Figure 1. All the other monitored sites showed similar large increases in waste volume.

Michael Ramsey [Pitt] discussed detecting volcanic eruption precursors using the entire ASTER TIR archive for six selected volcanoes: Etna, Fuego, Kliuchevskoi, Lascar, Vulcano, and Popocatepetl—four of these are shown in Figure 2. He and his students developed statistical methods to detect both low- and high-temperature anomalies. The team performed a cluster analysis on four volcanoes. By calculating and plotting heat flux versus mean temperature-above-background versus maximum temperature-above-background, clusters for eruption styles can be identified—see Figure 2. These results offer potential applicability to other volcanoes.

ASTER Figure 2
Figure 2. Three-dimensional plots show heat flux and temperature plots (further explained in the text) for hundreds of ASTER TIR scenes for four volcanoes, revealing differences related to eruptive styles. The lower cluster (blue) indicated fumarole and passive degassing; the medium cluster (red) correlated with domes and explosive and small lava flows; and the high clusters (green) correlated with large lava flows.

Calibration/Validation Working Group

This working group monitors the radiometric performance of ASTER’s VNIR and TIR instruments. The team performs calibration and validation of these instruments by analysis of onboard calibration lamps or blackbody, as well as measurements of pseudo-invariant ground targets during field campaigns. No changes in instrument performance were found based on validation activities during the past year. The radiometric calibration coefficients will remain unchanged for the foreseeable future.

Temperature–Emissivity Working Group

The Temperature–Emissivity Working Group focuses on ASTER’s kinetic temperature and emissivity (T–E) products and their applications, including monitoring instrument performance and calibration. They also review the status of the nighttime TIR global map program. In situ measurement campaigns in Japan and the U.S. use lakes and dry lake beds for ground-based calibration campaigns. Recent campaign results indicate that the TIR instrument perform within required calibration limits—see Figure 3. The team also noted the successful completion of the Visible Infrared Imaging Radiometer Suite (VIIRS)–ASTER 375-m (~1230-ft) near-real-time land-surface temperature algorithm using ASTER emissivity for corrections. Review of the thermal global mapping acquisition program indicated that it was proceeding as planned with no changes needed.

Operations and Mission Planning Working Group

The Operations and Mission Planning working group oversees and reviews the acquisition programs executed by the ASTER scheduler. The working group schedules ASTER data acquisitions daily to accommodate ASTER’s average 8% duty cycle. An automated program selects 600–700 daily scenes from the more than 3000 in the request archive. 

Tetsushi Tachikawa [JSS] 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 fill in the scenes for the daily quota. The objective is for ASTER to acquire at least one cloud-free image for every place on Earth. Due to persistent cloud cover, success is typically ~85%. The group restarts the program after several years, with the next scheduled restart in October 2024. The thermal group submits aerial requirements to acquire global nighttime coverage with the thermal bands, which will continue as scheduled. There are also acquisition programs that focus on islands, volcanoes, glaciers, and cloudy areas. 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. 

Chris Torbert [LPDAAC] reported that software fixes were ongoing for the (currently non-functional) expedited data processing at the LPDAAC.

Closing Plenary Session

Each working group chairperson summarized the presentations, discussions, and recommendations that occurred during each session. Consensus holds the ASTER instrument is operating normally, with no indications of any component failures. The backlog of unprocessed scenes resulting from the 2022 constellation exit maneuver impact on production software should clear by early October 2023. The closing highlighted the impact of the 50% budget reduction on the Flight Operation Team at GSFC with only a small increase in lost data (1–2%) due to the absence of operators to attempt immediate recovery. 

Conclusion

The fifty-second ASTER ST Meeting successfully covered all of the critical issues introduced during the opening plenary session. Working groups updated instrument scheduling, instrument performance, archiving plans, and new applications. The plan is for the 2024 meeting to take place at the same venue in Tokyo.

      The innovative team of engineers and scientists from NASA, the Johns Hopkins Applied Physics Laboratory in Laurel, Maryland, and more than 40 other partner organizations across the country that created the Parker Solar Probe mission has been awarded the 2024 Robert J. Collier Trophy by the National Aeronautic Association (NAA). This annual award recognizes the most exceptional achievement in aeronautics and astronautics in America with respect to improving the performance, efficiency, and safety of air or space vehicles in the previous year.   
      “Congratulations to the entire Parker Solar Probe team for this well-earned recognition,” said NASA acting Administrator Janet Petro. “This mission’s trailblazing research is rewriting the textbooks on solar science by going to a place no human-made object has ever been and advancing NASA’s efforts to better understand our solar system and the Sun’s influence, with lasting benefits for us all. As the first to touch the Sun and fastest human-made object ever built, Parker Solar Probe is a testament to human ingenuity and discovery.”
      An artist’s concept of NASA’s Parker Solar Probe. NASA On Dec. 24, 2024, Parker Solar Probe made its closest approach to the Sun, passing deep within the Sun’s corona, just 3.8 million miles above the Sun’s surface and at a top speed of close to 430,000 mph, ushering in a new era of scientific discovery and space exploration.
      “This award is a recognition of the unrelenting dedication and hard work of the Parker Solar Probe team. I am so proud of this team and honored to have been a part of it,” said Nicky Fox, associate administrator, Science Mission Directorate, NASA Headquarters in Washington. “By studying the Sun closer than ever before, we continue to advance our understanding of not only our closest star, but also stars across our universe. Parker Solar Probe’s historic close approaches to the Sun are a testament to the incredible engineering that made this record-breaking journey possible.”
      Three novel aerospace technology advancements were critical to enabling this record performance: The first is the Thermal Protection System, or heat shield, that protects the spacecraft and is built to withstand brutal temperatures as high as 2,500 degrees Fahrenheit. The Thermal Protection System allows Parker’s electronics and instruments to operate close to room temperature.
      Additional Parker innovations included first-of-their-kind actively cooled solar arrays that protect themselves from overexposure to intense solar energy while powering the spacecraft, and a fully autonomous spacecraft system that can manage its own flight behavior, orientation, and configuration for months at a time. Parker has relied upon all of these vital technologies every day since its launch almost seven years ago, in August 2018.
      “I am thrilled for the Parker Solar Probe team on receiving this well-deserved award,” said Joe Westlake, director of the Heliophysics Division at NASA Headquarters. “The new information about the Sun made available through this mission will improve our ability to prepare for space weather events across the solar system, as well as better understand the very star that makes life possible for us on Earth.”
      Parker’s close-up observations of solar events, such as coronal mass ejections and solar particle events, are critical to advancing our understanding of the science of our Sun and the phenomena that drive high-energy space weather events that pose risks to satellites, air travel, astronauts, and even power grids on Earth. Understanding the fundamental physics behind events which drive space weather will enable more reliable predictions and lower astronaut exposure to hazardous radiation during future deep space missions to the Moon and Mars.
      “This amazing team brought to life an incredibly difficult space science mission that had been studied, and determined to be impossible, for more than 60 years. They did so by solving numerous long-standing technology challenges and dramatically advancing our nation’s spaceflight capabilities,” said APL Director Ralph Semmel. “The Collier Trophy is well-earned recognition for this phenomenal group of innovators from NASA, APL, and our industry and research partners from across the nation.”
      First awarded in 1911, the Robert J. Collier Trophy winner is selected by a group of aviation leaders chosen by the NAA. The Collier Trophy is housed in the Smithsonian’s National Air and Space Museum in Washington.
      “Traveling three times closer to the Sun and seven times faster than any spacecraft before, Parker’s technology innovations enabled humanity to reach inside the Sun’s atmosphere for the first time,” said Bobby Braun, head of APL’s Space Exploration Sector. “We are all immensely proud that the Parker Solar Probe team will join a long legacy of prestigious aerospace endeavors that redefined technology and changed history.”
      “The Parker Solar Probe team’s achievement in earning the 2024 Collier is a shining example of determination, genius, and teamwork,” said NAA President and CEO Amy Spowart. “It’s a distinct honor for the NAA to acknowledge and celebrate the remarkable team that turned the impossible into reality.”
      Parker Solar Probe was developed as part of NASA’s Living With a Star program to explore aspects of the Sun-Earth system that directly affect life and society. The Living With a Star program is managed by the agency’s Goddard Space Flight Center in Greenbelt, Maryland, for NASA’s Science Mission Directorate in Washington. The Applied Physics Laboratory designed, built, and operates the spacecraft and manages the mission for NASA.

      “We have done our best with remote data, but the only way to truly understand the Moon—how to drill for resources, how to live on another celestial body—is to go there and do the experiments,” she said. “Now, we get to do that.”

      Lederer’s path to CLPS was shaped by a background in space exploration, astrophysics, and planetary science. She has contributed to multiple spacecraft missions, including NASA’s Deep Impact mission, which sent a projectile into Comet Tempel 1, and a separate mission that retrieved a sample from asteroid Itokawa.

      On Ascension Island, a remote joint U.S. Air Force and Royal Air Force base, she co-led the construction of a 20,000-pound optical telescope to study space debris. Her work spans collaborations with the Defense Advanced Research Projects Agency, a tenure as a physics professor, and the design of impact experiments at NASA’s Experimental Impact Lab, where she used a vertical gun firing projectiles at speeds exceeding those of sniper rifles to study asteroid and comet collisions.

      Lederer has logged hundreds of hours conducting observing runs at professional observatories worldwide, where she refined both her scientific precision and her ability to repair instruments while working alone on remote mountaintops.

      As a private pilot and SciComm (the science equivalent of Capsule Communicator) for NASA’s Desert Research and Technology Studies, she honed her mission communication skills. She was also part of an international team that discovered two extrasolar planetary systems—one with a single Earth-sized planet and another with seven—orbiting ultracool red dwarf stars.

      Her expertise has uniquely prepared her to oversee real-time science operations for lunar missions in high-intensity environments.

NASA/Robert Markowitz Lederer emphasizes the importance of both scientific discovery and the practical realities of living and working on another world—a challenge NASA is tackling for the first time in history.

      “Honestly, it’s when things don’t go as planned that you learn the most,” she said. “I’m looking forward to the surprises that we get to solve together as a team. That’s our greatest strength—the knowledge and teamwork that make this all happen.”

      Lederer credits the success of CLPS lunar deliveries to the dedication of teams working on payloads like Polar Resources Ice Mining Experiment-1 and Lunar Retroreflector Array, as well as peers within NASA’s Science Mission Directorate, Space Technology Mission Directorate, and Intuitive Machines.

      “What we do every day in CLPS creates a new world for exploration that is efficient in schedule, cost, and gaining science and technology knowledge in these areas like we’ve never done before,” said Lederer. “It feels very much like being a trailblazer for inspiring future generations of explorers – at least that’s my hope, to keep the next generation inspired and engaged in the wonders of our universe.”
