| | | | | |  | | Eight New Data Agreements Secured by NASA’s CSDA Program
The new Commercial Satellite Data Acquisition (CSDA) Program agreements advance the program's mission to acquire commercial data that supports NASA's Earth science research and applications, while expanding the quality, coverage, and variety of Earth observation data provided to the scientific community. | | | | | | | |  | | New SWOT L4 River Water Flow and Quality Estimates
These Surface Water and Ocean Topography (SWOT) L4 estimates enable data users to see rivers across the entire planet and support water resources management, weather extremes forecasting, and science research. | | | | | | | |  | | IMERG Shows Remnants of Gabrielle Led to Ibiza Flash Flooding
In mid-September 2025, Hurricane Gabrielle’s long track over the Atlantic reached the coast of Spain and Portugal. Gabrielle’s warm, moist air combined with an unstable atmosphere caused record-setting floods in Ibiza. This article uses several NASA datasets and services to examine the event. | | | | | | | |  | | The ARC Project Transitions to ESDIS
The Analysis and Review of the Common Metadata Repository (ARC) project is transitioning to Earth Science Data and Information System (ESDIS) management, continuing the important task of ensuring that NASA’s Earth observation metadata records are correct, complete, and consistent. | | | | | | | |  | | CSDA Program Releases New Data Acquisition Request System
A new dashboard within CSDA’s Satellite Data Explorer (SDX) streamlines how users submit and manage commercial satellite data proposals. | | | | | |

| | | | | | | | NASA Earth Science & Industry Summit February 2, 2026 This event, hosted by the U.S. Chamber of Commerce, connects NASA Earth science experts with industry stakeholders to use Earth observation to solve problems, drive economic development, and benefit society.
| |  | | | | | | | | | | Monitoring Water Quality in Lakes and Coastal Regions Using STREAM February 10 & 17, 2026 This two-part Applied Remote Sensing Training Program (ARSET) training introduces the Satellite-based Tool for Rapid Evaluation of Aquatic Environments (STREAM), a web tool for monitoring chlorophyll-a concentration, Secchi disk depth, and total suspended solids in inland lakes and coastal regions. The training demonstrates how to assess changes in water quality in a given lake using QGIS.
| |  | | | | | | | | | | Visualizing Land Cover and Land Use Change with NASA Satellite Imagery February 24 & 26, 2026 Learn how to use NASA data to assess land cover and land use change (LCLUC) during this two-part ARSET training. Participants will see examples of supervised and unsupervised classification models implemented in the R coding language and improve their understanding of how these models can be used to produce maps and metrics of LCLUC.
| |  | | | | | | | | | | Introducing NISAR: NASA’s Biggest Earth Observation Mission Recorded on January 21, 2026 The NASA/Indian Space Research Organization (ISRO) Synthetic Aperture Radar (NISAR) mission revolutionizes how we monitor Earth. Its instruments measure movements of Earth down to a centimeter, an incredible feat for a platform orbiting more than 800 kilometers away. Learn more in this webinar hosted by NISAR data scientists.
| |  | | | | | | | | | | National Civil Applications Center: Connecting Space-Based Resources to Civil Science, Research, and Disaster Applications Recorded on January 14, 2026 NASA’s CSDA Program provided an overview of the National Civil Applications Center (NCAC) and the Civil Applications Committee (CAC). These organizations complement CSDA by connecting national and commercial space-based remote sensing resources to civil science, research, federal operations, and disaster response.
