Goodbye Sentinel-1A 🥲. Phase-out starting.

It’s actually good news because the new Sentinel-1D satellite is almost ready to take over and data are to start flowing from mid of this month.

The complete new Sentinel-1 constellation is expected to be in place around early July.
The resulting constellation of Sentinel-1C and 1D will have a 6-day revisit cycle as the original constellation of 1A and 1B but shifted by 1 day.
