Sentinel-6 satellite

✓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.

✓The probe is named after the Chinese Moon goddess who is traditionally accompanied by a white or jade rabbit.

✓Early in 2019, China’s Chang’e-4 probe successfully transmitted images from the far side of the Moon, also referred to as the dark side.
