Seasat, an experimental U.S. ocean surveillance satellite was launched on 27 June, 1978. Each day, Seasat made 14 orbits of the Earth, and in a period of 36 hours was able to monitor nearly 96% of the oceanic surface. The measurement equipment on board was able to penetrate cloud cover and report measurements such as wave height, water temperature, currents, winds, icebergs, and coastal characteristics. Although it operated for only 99 days before a power failure, it had already shown the viability of the use of a satellite for collecting oceanic data. The information collected was shared with scientists and was used to aid transoceanic travel by ships and aircraft. Reference: britannica/EBchecked/topic/531015/Seasat, Retrieved 4 March, 2012
