ESA’s first Scout mission, HydroGNSS, launched on Nov. 28, 2025, marking a significant step in advancing global understanding of water availability and the effects of climate change on Earth’s water cycle.
The two twin HydroGNSS satellites were carried into orbit aboard a SpaceX Falcon 9 rocket from the Vandenberg Space Force Base in California.
Embracing the New Space concept, HydroGNSS is one of ESA’s new Scout missions being developed within the Earth Observation FutureEO program.
