After more than 11 years in orbit, the Ocean Surface Topography Mission (OSTM) on Jason-2 will permanently cease acquisition of scientific data at 06:48 UTC on 1 October 2019 due to aging-related issues onboard the spacecraft.  Approximately three hours later, the final pass 147 for science cycle 644 will be produced as an OGDR product and disseminated to operational users.  IGDR production will cease about 2.5 days later, GDR production approximately 2 months later.

The operation of the Jason-3 reference mission remains nominal and its continued data production will not be affected in any way.
