• Overview
    SWOT will make the first global survey of Earth's surface water, observe fine details of ocean surface topography, and measure how water bodies change over time.
  • Flight Systems
    The SWOT satellite observatory, consisting of a payload module and spacecraft bus, is being built by NASA JPL and the Centre National D'Études Spatiales.
  • Ground Systems & Data
    NASA and CNES will operate SWOT's ground systems, including satellite operation, acquisition of telemetry, and data processing, distribution, and archiving.
  • AirSWOT
    AirSWOT, an instrument supporting the SWOT mission, will help the engineering team better understand the natural properties of Earth's surfaces.
  • SWOT Visualizer
    Investigate the coverage of Earth's surface by two SWOT instruments: KaRIn Interferometer and altimeter.
  • Mission People
    Mission and Applications members of the SWOT Management Team.


  • Overview
    Using radar interferometry to measure water elevations, SWOT will help us assess water resources, sea level change, coastal processes, and fine ocean features.
  • Oceanography
    SWOT will revolutionize oceanography by detecting small-scale features that contribute to ocean-atmosphere exchange of heat and carbon at 10x current resolution.
  • Hydrology
    SWOT will provide the first global view of freshwater bodies to allow scientists to determine changing volumes of fresh water at unprecedented resolution.
