- The first of Two Satelites in sentinel mission, Sentinel-6 Michael Freilich satellite was launched recently.
About the Satellite:
- The Copernicus Sentinel-6 mission is a collaboration of the European Commission, the European Space Agency (ESA), EUMETSAT, NASA and the US National Oceanic and Atmospheric Administration (NOAA).
- Sentinel-6a will be the first of two identical satellites -- the second to be launched in five years -- that will provide measurements of unprecedented precision until at least 2030.
- The twin satellites will measure sea-level rise, tracking changes threatening to disrupt tens of millions of lives within a generation.
- Each Sentinel-6 probe carries a radar altimeter, which measures the time it takes for radar pulses to travel to Earth’s surface and back again.
- They are designed to last for five-and-a-half years but could provide data for far longer.
- The Sentinel-6 mission is part of the Copernicus programme initiative which is European Union's Earth observation programme coordinated and managed by the European Commission in partnership with the European Space Agency (ESA), the EU Member States and EU Agencies.
