Background: Although three fourths of the earth is covered by water, we know very little about the seas on which our ships sail.
Each year, hundreds of ships and tons of cargo are lost at sea because of bad weather... Or icebergs.
Now, however, a new satellite will survey the oceans of the world, sending back data on wave heights, surface winds and temperature currents, ice conditions, ocean topography, an? coastal storms.
It's called Seasat A, and it was built by Lockhe Missiles & Space Company for the National Aeronautics and Space Administration (NASA). The Jet Propulsion Laboratory is managing the program for NASA. This experimental satellite uses microwave sensors, instead of photography, to make its oceanographic measurements.
Satellites such as Seasat will not only improve navigation, but also Help locate the best fishing areas, Provide warnings of storms approaching offshore oil platforms,
Assist the Navy in preparing weather maps and advisories for ships.
And aid the Coast Guard in search and rescue missions.
Following successful testing at Lockheed, Seasat A was shipped to Vandenberg Air Force Base. Launch is scheduled for June 10 and is open to the public.
