Ocean Surface Topography Mission
The Ocean Surface Topography Mission (OSTM/Jason-2) continued the TOPEX/Poseidon and Jason-1 ocean-altimetry record through a NASA, CNES, NOAA and EUMETSAT partnership. Launched on June 20, 2008, it measured sea-surface height for circulation, climate and operational oceanography. After reference-track operations, it moved to an interleaved orbit in 2016 and a lower, long-repeat geodetic orbit in 2017, increasing spatial coverage. Science acquisition ended on October 1, 2019 after deterioration of the spacecraft's power system; final decommissioning followed later that month.
