If you design a new tool for use on Earth, it is easy to test and practice using that tool in its intended environment. But what if that tool is destined for lunar orbit or will be used by astronauts on the surface of the Moon?
NASA’s Simulation and Graphics Branch can help with that. Based at Johnson Space Center in Houston, the branch’s high-fidelity, real-time graphical simulations support in-depth engineering analyses and crew training, ensuring the safety, efficiency, and success of complex space endeavors before execution. The team manages multiple facilities that provide these simulations, including the Prototype Immersive Technologies (PIT) Lab, Virtual Reality Training Lab, and the Systems Engineering Simulator (SES).
Lee Bingham is an aerospace engineer on the simulation and graphics team. His work includes developing simulations and visualizations for the NASA Exploration Systems Simulations team and providing technical guidance on simulation and graphics integration for branch-managed facilities. He also leads the branch’s human-in-the-loop Test Sim and Graphics Team, the Digital Lunar Exploration Sites Unreal Simulation Tool (DUST), and the Lunar Surface Mixed-Reality with the Active Response Gravity Offload System (ARGOS) projects.
Lee Bingham demonstrates a spacewalk simulator for the Gateway lunar space station during NASA’s Tech Day on Capitol Hill in Washington, D.C. Image courtesy of Lee Bingham Bingham is particularly proud of his contributions to DUST, which provides a 3D visualization of the Moon’s South Pole and received Johnson’s Exceptional Software of the Year Award in 2024. “It was designed for use as an early reference to enable candidate vendors to perform initial studies of the lunar terrain and lighting in support of the Strategy and Architecture Office, human landing system, and the Extravehicular Activity and Human Surface Mobility Program,” Bingham explained. DUST has supported several human-in-the-loop studies for NASA. It has also been shared with external collaborators and made available to the public through the NASA Software Catalog.
Bingham has kept busy during his nearly nine years at Johnson and said learning to manage and balance support for multiple projects and customers was very challenging at first. “I would say ‘yes’ to pretty much anything anyone asked me to do and would end up burning myself out by working extra-long hours to meet milestones and deliverables,” he said. “It has been important to maintain a good work-life balance and avoid overcommitting myself while meeting demanding expectations.”
Lee Bingham tests the Lunar Surface Mixed Reality and Active Response Gravity Offload System trainer at Johnson Space Center. Image courtesy of Lee Bingham Bingham has also learned the importance of teamwork and collaboration. “You can’t be an expert at everything or do everything yourself,” he said. “Develop your skills, practice them regularly, and master them over time but be willing to ask for help and advice. And be sure to recognize and acknowledge your coworkers and teammates when they go above and beyond or achieve something remarkable.”

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 NASA 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, such as 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 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.
Photo 1. NASA’s DC-8 flying laboratory flew Earth science missions from 1987 to 2024. Expert maintenance allowed the aircraft to conduct research on six continents and study ice fields on the seventh, Antarctica. Image Credit: Lori Losey/NASA 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.”

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.
