Title
Artist's Concept of Seasat-A
Full Description
An artist's concept of Seasat A, the first spacecraft dedicated for
oceanographic studies. Seasat A was designed for monitoring the
Earth's oceans with active microwave instruments. The scientific
objectives were to collect data on sea-surface winds, oceanography,
sea-surface temperatures, wave heights, wavelength and direction,
atmospheric water, and sea ice features. Seasat-A was launched on
June 16, 1978, on an Atlas-Agena launch vehicle from Vandenberg
Air Force Base, California. The mission ended after 116 days due
to a failure of the spacecraft's electric power system. The mission
demonstrated the feasibility of using microwave sensors to monitor
ocean conditions, and laid the groundwork for future ocean
missions. The science of oceanography began more than 100 years
ago with the sailing of HMS Challenger. Challenger's round-the-
world trip became the model for oceanographic voyages.
