HydroGNSS satellites being prepared for launch

After arriving at the California launch site, the two HydroGNSS satellites have been carefully prepared for liftoff, scheduled for November. HydroGNSS – a twin-satellite mission – marks the European Space Agency’s first ‘Scout’ venture. By harnessing signals from navigation satellites, HydroGNSS will help scientists gain new insights into key climate variables linked to water.

Since their arrival, the HydroGNSS satellites have undergone a series of final checks – including testing, propellant loading, battery charging and integration with their launch adapter.
