<\/a><\/figure>NASA will provide live coverage of prelaunch and launch activities for Sentinel-6B, an international mission delivering critical sea level and ocean data to protect coastal infrastructure, improve weather forecasting, and support commercial activities at sea.<\/p>\n
Launch is targeted at 12:21 a.m. EST, Monday, Nov. 17 (9:21 p.m. PST, Sunday, Nov. 16) aboard a SpaceX Falcon 9 rocket from Space Launch Complex 4 East at Vandenberg Space Force Base in California.<\/p>\n
Watch coverage beginning at 11:30 p.m. EST (8:30 p.m. PST) on NASA+, Amazon Prime, and more. Learn how to watch NASA content<\/a> through a variety of platforms, including social media.<\/p>\n The Sentinel-6B mission continues a decades-long effort to monitor global sea level and ocean conditions using precise radar measurements from space. Since the early 1990s, satellites launched by NASA and domestic and international partners have collected precise sea level data. The launch of Sentinel-6B will extend this dataset out to nearly four decades.<\/p>\n NASA\u2019s mission coverage is as follows (all times Eastern and subject to change based on real-time operations):<\/p>\n Saturday, Nov. 15<\/strong><\/p>\n 4 p.m. \u2013 NASA Prelaunch Teleconference on International Ocean Tracking Mission<\/p>\n Audio of the teleconference will stream on the NASA Video YouTube channel<\/a>. \u00a0<\/p>\n Media interested in participating by phone must RSVP no later than two hours prior to the start of the call at: ksc-newsroom@mail.nasa.gov<\/a>.

The first satellite in the mission, Sentinel-6 Michael Freilich<\/a>, launched in November 2020. The European Commission contributed funding support, while France\u2019s space agency CNES (Centre National d\u2019\u00c9tudes Spatiales) provided technical expertise. The mission also marks the first international involvement in Copernicus, the European Union\u2019s Earth Observation Programme.<\/p>\n For more information about these missions, visit:<\/p>\n https:\/\/science.nasa.gov\/mission\/sentinel-6b\/<\/strong><\/a><\/p>\n -end-<\/p>\n Elizabeth Vlock Leejay Lockhart Andrew Wang \/ Andrew Good\n
