Sea-level monitoring satellite first results surpass expectations Launched less than three weeks ago, the Copernicus Sentinel-6 Michael Freilich satellite has not only returned its first data, but results also show that it is functioning far better than expected. Thanks to its new, sophisticated, altimetry technology, Sentinel-6 is poised to deliver exceptionally precise data on sea-level height to monitor the worrying trend of sea-level rise. Sentinel-6 Michael Freilich was lofted into orbit on 21 November from California. After it had sent back its first signal showing that it was alive and well in space, ESA’s Operations Centre in Germany took care of the satellite’s first few days in orbit before handing it over to Eumetsat for commissioning, and eventual routine operations and distribution of data. ....
BBC News By Jonathan Amos image captionArtwork: Sentinel-6 carries an altimeter to measure the elevation of water surfaces The new satellite that will become the primary orbital tool for tracking sea-level rise is in excellent shape. Sentinel-6 Michael Freilich was only launched three weeks ago, but already it is mapping ocean features in exquisite detail. The dog kennel-shaped spacecraft is a joint endeavour between Europe and the US. It is the latest iteration in a series of missions that have been measuring sea-surface height going back to 1992. These earlier satellites have shown unequivocally that the oceans globally are rising at a rate in excess of 3mm per year over the 28-year period, with an acceleration apparent in the last decade. ....
