Aquarius (satellite)

Aquarius is a satellite launched by NASA to study Earth's ocean surface. It uses specialized sensors to measure Sea Surface Salinity (how salty the ocean water is) across the globe. These measurements help scientists understand ocean circulation, climate patterns, and the water cycle, because salinity affects how seawater moves and interacts with the atmosphere. Aquarius provides critical data to improve weather forecasting, climate models, and our understanding of the Earth's changing environment. It orbits the planet, collecting continuous information that aids in tracking long-term ocean and climate trends.
