Objective
Test oceanographic sensors and monitor Earth's seas
One of the earliest Earth-observing satellites, Seasat was designed to test various oceanographic sensors and gain a better understanding of Earth's seas. It measured sea-surface winds and temperatures, wave heights, atmospheric water content, sea ice features, and ocean topography, before succumbing to an onboard short circuit after 105 days.
