✓The Copernicus Sentinel-6 Michael Freilich satellite was launched aboard a SpaceX Falcon 9 rocket
✓Objective: Designed to monitor oceans
✓Developed jointly by: European Space Agency (ESA), NASA, European Organisation for the Exploitation of Meteorological Satellites (Eumetsat), the USA’s National Oceanic and Atmospheric Administration (NOAA) and the EU.
✓This is a part of the next mission dedicated to measuring changes in the global sea level.
✓The mission, called the Jason Continuity of Service (Jason-CS) mission, is designed to measure the height of the ocean.
✓Height of the ocean is a key component in understanding how the Earth’s climate is changing.
✓The spacecraft consists of two satellites, out of which one was launched recently, and the other, called Sentinel-6B, shall be launched in 2025.
✓Other satellites that have been launched since 1992 to track changes in the oceans on a global scale include the TOPEX/Poseidon, Jason-1 and OSTN/Jason-2, among others.
