ESA’s HydroGNSS Scout satellites ready for launch

After arriving at the California launch site at the end of September, the two HydroGNSS satellites have been carefully prepared for liftoff, scheduled this month.

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.
