United States, Nov. 17 -- The Airbus-built Sentinel-6B satellite has successfully launched from Vandenberg Space Force Base in California. This is the second of two identical satellites built to continue collecting essential sea-surface height data until at least 2030. The first satellite, Sentinel-6 Michael Freilich, was launched in November 2020.For its first year, Sentinel-6B will join Sentinel-6 Michael Freilich in orbit, allowing both instruments to collaborate, thus providing the most accurate data on global sea levels. This information is fundamental in warning coastal countries of potential dangers and for continuity of successful ocean weather forecasts. Sentinel-6B will carry out high-precision ocean surface topography measurement...
