Mission Summary

One of the earliest Earth-observing satellites, Seasat was designed to test various oceanographic sensors and gain a better understanding of Earth's seas.

Seasat operated in Earth orbit for 105 days, measuring sea-surface winds and temperatures, wave heights, atmospheric liquid water content, sea ice features and ocean topography, before a massive short circuit in the spacecraft's electrical system ended the mission on October 10, 1978.
