    Streaming Coverage Begins for Sentinel-6B Launch

    Night time image shows a white SpaceX rocket at the launch pad in California on Sunday, Nov. 16, 2025. Atop the rocket is a white payload fairing encapsulating NASA's Sentinel-6B spacecraft

    Live coverage is underway for launch of Sentinel-6B from Space Launch Complex 4 East at Vandenberg Space Force Base in California. Weather remains 90% favorable with thick clouds and cumulus clouds as the possible weather violations during the 12:21 a.m. EST (9:21 p.m. PST Sunday, Nov. 16) liftoff. Sentinel-6B is part of a series of […]

    Sentinel-6B: Monitoring Earth’s Sea-Levels

    Artist’s concept illustration showing a gold-colored satellite at the center of the image with a black, star-filled background behind it. The Earth’s surface, blue and cloud-covered, fills the lower-left corner of the frame, from the center-left edge to the bottom-center of the frame. On the surface directly below the satellite, a spiral hurricane is visible. The satellite is shaped like a house with a peaked roof, viewed from an angle, with the pentagon-shaped front and left side side both facing the viewer. The satellite’s solar arrays form what looks like a very wide peaked roof atop the satellite, extending far beyond the side walls. Underneath the satellite, a silver cone-shaped instrument points down toward Earth. Another instrument on the front side, shaped like a silver frying pan, also faces toward Earth. In the upper right corner of the image is bright lens flare from the Sun, out of frame.

    The launch of Sentinel-6B will continue a joint mission between NASA and its European partners to monitor sea levels. This data is key to helping improve public safety, city planning, and protecting commercial and defense interests. Along with measuring global sea level rise and ocean circulation, the satellites record vertical profiles of atmospheric temperature and […]
