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.

Bassac River, Southern Vietnam
A camera on the International Space Station captured this Oct. 2, 2025, photo of the Bassac River in Cù Lao Dung, a river islet district in southern Vietnam. The Bassac River surrounds the district before emptying into the South China Sea. The river’s brown waters at its mouth result from massive amounts of silt, clay, […]
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 […]

NASA, European Partners Set to Launch Sentinel-6B Earth Satellite
Set to track sea levels across more than 90% of Earth’s ocean, the mission must first get into orbit. Here’s what to expect. Sentinel-6B, an ocean-tracking satellite jointly developed by NASA and ESA (European Space Agency), is ready to roll out to the launch pad, packed into the payload fairing of a SpaceX Falcon 9 […]
6 Things to Know From NASA About New US, European Sea Satellite
Data from Sentinel-6B will continue a decades-long record of sea surface height, helping to improve coastal planning, protect critical infrastructure, and advance weather forecasts. With launch set for no earlier than 12:21 a.m. EST Monday, Nov. 17, Sentinel-6B is the latest satellite in a series of spacecraft NASA and its partners have used to measure […]
