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 […]

Golden Lake
Golden sunglint highlights Lake Balkhash in this May 31, 2016, photo taken from the International Space Station. The large lake in Kazakhstan is one of the largest lakes in Asia and is the 15th largest lake in the world. Since the space station became operational in November 2000, crew members have produced hundreds of thousands […]
Arctic Sea Ice Reaches Annual Low
With the end of summer approaching in the Northern Hemisphere, the extent of sea ice in the Arctic shrank to its annual minimum on Sept. 10, according to NASA and the National Snow and Ice Data Center. The total sea ice coverage was tied with 2008 for the 10th-lowest on record at 1.78 million square […]
NASA’s GUARDIAN Tsunami Detection Tech Catches Wave in Real Time
A massive earthquake and subsequent tsunami off Russia in late July tested an experimental detection system that had deployed a critical component just the day before. A recent tsunami triggered by a magnitude 8.8 earthquake off Russia’s Kamchatka Peninsula sent pressure waves to the upper layer of the atmosphere, NASA scientists have reported. While the […]
Thinning Arctic Sea Ice
Sea ice is frozen seawater that floats in the ocean. This photo, taken from NASA’s Gulfstream V Research Aircraft on July 21, 2022, shows Arctic sea ice in the Lincoln Sea north of Greenland. This image is the NASA Science Image of the Month for September 2025. Each month, NASA’s Science Mission Directorate chooses an image to […]
