The mission will provide critical data on soil moisture, wetlands, freeze\u2013thaw states in permafrost, and above-ground biomass, while also monitoring ocean wind speeds and sea-ice extent. These measurements will support climate monitoring, agriculture, meteorology, and disaster mitigation planning, offering continuity with ESA\u2019s SMOS mission and complementing the upcoming Biomass mission.<\/p>\n<p>By delivering open and free data products, HydroGNSS aims to strengthen global efforts to track Essential Climate Variables (ECVs) defined by the Global Climate Observing System. The mission\u2019s near-continuous coverage will provide scientists and policymakers with valuable insights into water-related climate processes, helping to address challenges such as droughts, floods, and long-term climate change. As ESA\u2019s first Scout mission, HydroGNSS represents a bold step toward agile, small-satellite innovation in Earth observation.<\/p>\n<div class=\"new-product-widget related-content-list my-3\">\n<h4 class=\"heading\">Related Links<\/h4>\n<ul class=\"list-unstyled mb-0\">\n<li><i class=\"fa fa-sm fa-angle-right text-primary\"><\/i>ESA&#8217;s SMOS Mission Details<\/li>\n<li><i class=\"fa fa-sm fa-angle-right text-primary\"><\/i>ESA Shortlists Spaceport Cornwall for INVICTUS Hypersonic Test Programme<\/li>\n<\/ul>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>The European Space Agency (ESA) is preparing to launch HydroGNSS, its first Scout mission, designed to track Earth\u2019s water cycle and climate variables using innovative satellite technology.
