CRISTAL (Sentinel 9)

CRISTAL (Copernicus Polar Ice and Snow Topography Altimeter) or Sentinel 9 is an earth observation mission in the framework of ESA's Copernicus program.

CRISTAL will carry a multi-frequency radar altimeter and microwave radiometer to measure and monitor sea-ice thickness and overlying snow depth. It would also measure and monitor changes in the height of ice sheets and glaciers around the world. Measurements of sea-ice thickness would support maritime operations in polar oceans and, in the longer term would help in the planning of activities in the polar regions. Since inter-annual sea-ice variability is sensitive to climate change, the mission would contribute to a better understand of climate processes.

In July 2020, ESA signed a contract with Airbus Defence and Space as a prime contractor to build the satellite.
