Jointly developed and managed by NASA and Frances CNES, with contributions from the Canadian Space Agency and UK Space Agency, SWOT makes a global survey of Earths surface water, measuring ocean-surface topography and changes in lakes, rivers, reservoirs, wetlands, and other water bodies.
Destination
Non-sun-synchronous Earth orbit at approximately 857 km during calibration, then 891 km at 77.6° inclination with a 21-day repeat cycle
Outcome
Successful and active. SWOT launched on 16 December 2022 and now provides global space-based measurements of Earth’s surface water, including ocean-surface topography and observations of lakes, reservoirs, and rivers, supporting hydrology, oceanography, climate, and water-resource research.
