Update : ESA is progressing fast. All lands overflown by Sentinel-2B were available in PEPS on November 12th, thanks to EDRS relay satellites.
The Sentinel-2 mission, made of two twin satellites S2A and S2B, has been stated « operational » since beginning of October, even if each satellite was only observing on one orbit out of two everywhere except in Europe and Africa. As a result, the 5 days revisit was only available in these two continents. But in the new Sentinel-2 mission status report, ESA announced this very good piece of news :
Sentinel-2A and -2B are together acquiring Europe, Africa and Greenland with 5 days revisit. The rest of the World is revisited every 10 days jointly by the two satellites. Full systematic 5-day revisit everywhere will be reached once EDRS downlink becomes available operationally, assumed during December 2017 for both S2A and S2B.
The « EDRS downlink » uses a laser terminal on board S2A and S2B, that sends data to a
