NASA’s Ames Research Center in California’s Silicon Valley, is celebrating 85 years of cutting-edge research and development in space, life sciences, supercomputing, aeronautics, and more for the benefit of humanity. Ames was founded as an aeronautical laboratory in December 1939, and has since contributed to many of NASA’s flagship missions from Apollo to Artemis.
NASA Ames experts are available for interviews Thursday, Dec. 19, and Friday, Dec. 20. To request an interview about the center’s legacy in space, science, technology, and aeronautics, email the Ames newsroom at: arc-dl-newsroom@mail.nasa.gov.
NASA Ames experts include:
James Anderson, NASA Ames historian; Lynn Harper, lead of integrative studies in the NASA Space Portal, working to propel U.S. industry toward the development of a sustainable, scalable, and profitable non-NASA demand for services and products manufactured in the microgravity environment of low Earth orbit; Shivanjli Sharma, aerospace research engineer, working to enable advanced aviation technologies for new methods of air cargo and passenger transportation in urban, suburban, rural, and regional communities; Dave Alfano, chief of the Ames Intelligent Systems Division, working to produce ground and flight software systems and data architectures for data mining, analysis, integration, and management; integrated health management, and more for missions across the agency. Ames has established itself as a leader in the aeronautics industry, developing foundational technologies for advanced air vehicles, including air taxis and remotely piloted aircraft. On the International Space Station, Ames researchers have tested a method to develop nutrients off-Earth and on-demand. Cube-shaped robots have been delivered to the station to assist astronauts with routine duties. Ames engineers have developed and are testing a heat shield for the Orion crew capsule that will safely return astronauts home to Earth as part of the agency’s Artemis missions to the Moon.

At Goddard Space Flight Center, the GSFC Data Science Group has completed the testing for their SatVision Top-of-Atmosphere (TOA) Foundation Model, a geospatial foundation model for coarse-resolution all-sky remote sensing imagery. The team, comprised of Mark Carroll, Caleb Spradlin, Jordan Caraballo-Vega, Jian Li, Jie Gong, and Paul Montesano, has now released their model for wide application in science investigations.
Foundation models can transform the landscape of remote sensing (RS) data analysis by enabling the pre-training of large computer-vision models on vast amounts of remote sensing data. These models can be fine-tuned with small amounts of labeled training and applied to various mapping and monitoring applications. Because most existing foundation models are trained solely on cloud-free satellite imagery, they are limited to applications of land surface or require atmospheric corrections. SatVision-TOA is trained on all-sky conditions which enables applications involving atmospheric variables (e.g., cloud or aerosol).
SatVision TOA is a 3 billion parameter model trained on 100 million images from Moderate Resolution Imaging Spectroradiometer (MODIS). This is, to our knowledge, the largest foundation model trained solely on satellite remote sensing imagery. By including “all-sky” conditions during pre-training, the team incorporated a range of cloud conditions often excluded in traditional modeling. This enables 3D cloud reconstruction and cloud modeling in support of Earth and climate science, offering significant enhancement for large-scale earth observation workflows.
With an adaptable and scalable model design, SatVision-TOA can unify diverse Earth observation datasets and reduce dependency on task-specific models. SatVision-TOA leverages one of the largest public datasets to capture global contexts and robust features. The model could have broad applications for investigating spectrometer data, including MODIS, VIIRS, and GOES-ABI. The team believes this will enable transformative advancements in atmospheric science, cloud structure analysis, and Earth system modeling.
The model architecture and model weights are available on GitHub and Hugging Face, respectively. For more information, including a detailed user guide, see the associated white paper: SatVision-TOA: A Geospatial Foundation Model for Coarse-Resolution All-Sky Remote Sensing Imagery.
Examples of image reconstruction by SatVision-TOA. Left: MOD021KM v6.1 cropped image chip using MODIS bands [1, 3, 2]. Middle: The same images with randomly applied 8×8 mask patches, masking 60% of the original image. Right: The reconstructed images produced by the model, along with their respective Structural Similarity Index Measure (SSIM) scores. These examples illustrate the model’s ability to preserve structural detail and reconstruct heterogeneous features, such as cloud textures and land-cover transitions, with high fidelity.NASAView the full article

Media are invited to learn about a unique series of flight tests happening in Virginia in partnership between NASA and GE Aerospace that aim to help the aviation industry better understand contrails and their impact on the Earth’s climate. Contrails are the lines of clouds that can be created by high-flying aircraft, but they may have an unseen effect on the planet – trapping heat in the atmosphere.
The media event will occur from 9 a.m.-12 p.m. on Monday, Nov. 25 at NASA’s Langley Research Center in Hampton, Virginia. NASA Langley’s G-III aircraft and mobile laboratory, as well as GE Aerospace’s 747 Flying Test Bed (FTB) will be on site. NASA project researchers and GE Aerospace’s flight crew will be available to discuss the Contrail Optical Depth Experiment (CODEX), new test methods and technologies used, and the real-world impacts of understanding and managing contrails. Media interested in attending must contact Brittny McGraw at brittny.v.mcgraw@nasa.gov no later than 12 p.m. EST, Friday, Nov. 22.
Flights for CODEX are being conducted this week. NASA Langley’s G-III will follow GE Aerospace’s FTB in the sky and scan the aircraft wake with Light Detection and Ranging (LiDAR) technology. This will advance the use of LiDAR by NASA to generate three-dimensional imaging of contrails to better characterize how contrails form and how they behave over time.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
Hundreds of students, scientists, and other stakeholders listen in person and online as NASA leaders discuss the Artemis missions during the 2023 von Braun Space Exploration Symposium held Oct. 25–27 at the University of Alabama in Huntsville. NASA / Charles Beason Media are invited to attend the 2024 von Braun Space Exploration Symposium Monday Oct. 28 to Wednesday, Oct. 30 at the University of Alabama in Huntsville.
Organized by the American Astronautical Society in collaboration with NASA’s Marshall Space Flight Center in Huntsville, the annual symposium gathers leaders from across government, industry, policy, and academia to discuss the current landscape of space exploration and chart a path forward amid the challenges that lie ahead.
The theme of this year’s event is “Expanding Exploration: From Vision to Reality,” focusing on NASA’s and Marshall’s plans for the future and the broader discourse about exploration and discovery, technology, the workforce, and other elements of the space ecosystem.
Media members interested should register with the astronautical society as a media representative under these guidelines for in-person or online attendance.
Marshall Center Director Joseph Pelfrey will deliver opening remarks on Oct. 28, followed by panels on Artemis, artificial intelligence, and workforce development. NASA Deputy Associate Administrator Casey Swails will deliver a keynote address to close out the first day.
Panels on, Oct. 29, will focus on space nuclear propulsion, science, and lunar logistics and mobility. Col. Eric Zarybnisky, Office of Space Launch director at the National Reconnaissance Office, will provide the luncheon keynote.
The third and final day of the symposium Oct. 30, will include discussions on nuclear propulsion, space technology, and human exploration beyond low-Earth orbit. NASA Associate Administrator Jim Free and Wayne Hale, who retired in 2010 as the deputy associate administrator of strategic partnerships at NASA Headquarters in Washington, will lead a discussion and present awards at the closing luncheon.
To arrange interviews with NASA Marshall speakers, contact Hannah Maginot, 256-932-1937, or Molly Porter, 256-424-5158.
