Springtime weather is melting the ice covering Hudson Bay in Canada, causing it to shift and recede from the shorelines. @NOAA’s JPSS satellites captured this changing view from April 14 to May 3, 2026. Credit: NOAA/@CIRA_CSU

A new milestone for @NOAA’s upcoming #JPSS4 satellite has been reached with the successful integration of Libera, a @NASA-funded instrument built by @LASPatCU! Libera will help measure reflected solar energy and heat emitted by Earth. Learn more: nesdis.noaa.gov/our-satellit…
A view of a section of the JPSS-4 satellite, featuring the integrated Libera instrument. The spacecraft and its components are heavily covered in bright golden-orange thermal insulation. Several protruding parts are wrapped in white protective covers, one of which features bold red text reading \"Remove before flight.\" Bundles of blue and white cables hang loosely beneath the satellite body. The background shows a softly blurred cleanroom setting with work chairs, tables, and a black-and-yellow caution tape.

Happy #EarthDay! 🌎✨ In this view of Earth from April 21, 2026, #NOAA21 is helping keep watch from above. Orbiting pole to pole 14 times a day, @NOAA’s JPSS satellites provide full global coverage twice daily and support U.S. weather forecasting and severe weather monitoring.
Global satellite view of Earth from April 21, 2026, centered on North and South America, with swirling white clouds against a dark background. A NOAA logo can be seen in the bottom right corner.

A clipper system moving across North America was seen by the #NOAA20 satellite on April 8, 2026. This enhanced-color view shows the storm’s cloud structure as it brought wind, cooler temperatures, and snow to the Northern Plains and southern Canada. 🌨️ Credit: NOAA/@CIRA_CSU
Satellite image of a large storm system stretching across central North America observed on April 8, 2026, with a swirl centered over the western United States and broad cloud bands extending into the Plains, Great Lakes, and southern Canada. The enhanced-color day cloud phase view shows cloud patterns in shades of blue, yellow, orange, and red. NOAA and CIRA logos appear in the lower-right corner.

River ice jams can block rivers like a temporary dam, increasing flood risk. @NOAA’s JPSS satellites provide near real-time maps of river ice and flooding using #VIIRS flood products to help forecasters track changing conditions. Read more: nesdis.noaa.gov/news/leo-sat…

In Alaska’s remote environment, @NOAA’s JPSS satellites provide frequent observations that support weather forecasting and hazard monitoring. This sequence shows one example as volcanic ash billows from Mount Shishaldin on Oct. 3, 2023. Read more: nesdis.noaa.gov/news/the-cri…

A nor’easter off the Northeast U.S. coast was observed by @NOAA’s JPSS satellites on Feb. 23, 2026. This enhanced-color view shows the storm’s swirling cloud structure over the Atlantic. The system brought blizzard conditions to parts of the region. ❄️ Credit: NOAA/@CIRA_CSU
Satellite image of an intense coastal storm swirling off the Northeast coast of the United States, with thick cloud bands curling over the Atlantic. The enhanced-color \u201Cday cloud phase\u201D view highlights cloud patterns in vivid blues, greens, yellows, and reds. A NOAA and CIRA logo are located in the lower-right corner.

Solar array deployment test milestone complete! 🛰️☀️ @NOAA’s #JPSS4 solar array was tested ahead of launch by @NASA and @NorthropGrumman. @NOAASatellites will operate JPSS-4 after launch. Learn more about this critical test: nesdis.noaa.gov/news/noaas-n…
The JPSS-4 satellite\u2019s solar panels, shown as a short series of large squares with blue dotted segments, appear to be unfolding from the satellite body. About eight technicians in white protective suits stand around the spacecraft, observing the deployment. At the back of the image, the satellite bus is wrapped in orange mylar, while the panels unfold in front of it. This milestone ensures the panels deploy correctly so the satellite can generate power in space. Credit: Northrop Grumman.
