OPERA: Addressing Societal Needs with Satellite Data

Introduction The Observational Products for End-Users from Remote Sensing Analysis (OPERA) project represents a strategic initiative designed to address critical satellite data needs identified by federal agencies. Established in 2021 by the NASA/Jet Propulsion Laboratory (JPL), OPERA responds to priorities identified by the Satellite Needs Working Group (SNWG), an interagency body convened by the White […]

Sentinels in the Sky: 50 Years of GOES Satellite Observations

Introduction In an era where satellite observations of Earth are commonplace, it’s easy to forget that only a few decades ago, the amount of information available about the state of Earth’s environment was limited; observations were infrequent and data were sparsely located. As far back as the late 1950s, there were primitive numerical weather prediction […]

Keeping Up with PACE: Summary of the 2025 PAC3 Meeting

Introduction Launched in Feb. 2024, NASA’s Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) mission is a cornerstone of Earth system science designed to deepen our understanding of how these environmental and biological components come together to influence our climate, carbon cycle, and ecosystems. PACE has funded three supporting components: the PACE Postlaunch Airborne eXperiment (PACE–PAX), the […]

Sentinel-6B Extends Global Ocean Height Record

Introduction On November 16, 2025, the Sentinel-6B satellite launched from Vandenberg Space Force Base (VSFB) in California. The mission is a partnership between NASA, the National Oceanic and Atmospheric Administration (NOAA), and several European partners – the European Space Agency (ESA), the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT), the French Centre National […]

NASA, Partners Share First Data From New US-European Sea Satellite

Launched in November, Sentinel-6B will track ocean height with ultraprecision to advance marine forecasting, national security, and more. Sentinel-6B, a joint mission by NASA and its U.S. and European partners to survey 90% of the world’s oceans for the benefit of communities and commerce, has started sending back its first measurements since launching in November. […]

25 Year of Scientific Discovery Aboard International Space Station

November marks 25 years of human presence aboard the International Space Station, a testament to international collaboration and human ingenuity. Since the first crew arrived on Nov. 2, 2000, NASA and its partners have conducted thousands of research investigations and technology demonstrations to advance exploration of the Moon and Mars and benefit life on Earth. […]

NASA, Aerospace Corporation Study Sharpens Focus on Ammonia Emissions

The pungent gas contributes to fine airborne particulate pollution, which endangers human health when inhaled and absorbed in the bloodstream.  A recent study led by scientists at NASA’s Jet Propulsion Laboratory in Southern California and the nonprofit Aerospace Corporation shows how high-resolution maps of ground-level ammonia plumes can be generated with airborne sensors, highlighting a […]
