GRACE (Gravity Recovery and Climate Experiment)

GRACE (Gravity Recovery and Climate Experiment) is a satellite mission that measures Earth's gravity field with high precision. By detecting tiny changes in gravity, it helps scientists monitor shifts in ice sheets, groundwater, and ocean currents, revealing how climate and water resources are changing over time. The data collected provides critical insights into environmental and climate dynamics, informing efforts to understand and address global issues like sea-level rise and water availability. Essentially, GRACE acts like a scale that weighs Earth's mass distribution continuously, helping us track natural and human-induced changes on our planet.
