Summary:

- The Sentinel-6B satellite is the latest in a series of satellites that have been monitoring the global sea level for over 30 years. It is a joint mission between NASA, the European Space Agency, and other international partners.
- Sentinel-6B will continue the critical task of measuring the height of the global ocean, which is an important indicator of climate change. As the Earth's temperature rises, the ocean expands and sea levels increase, which can have significant impacts on coastal communities.
- The data collected by Sentinel-6B will help scientists better understand the complex processes that are driving changes in the Earth's climate and oceans, and will aid in the development of strategies to mitigate the effects of sea level rise.
