Seasat was the first satellite designed specifically to monitor the oceans with radar. Launched in 1978, the satellite operated for 98 days and acquired enough data to produce imagery of 100 million square kilometers of the Earth's surface. Seasat orbited the Earth at an altitude of 800 kilometers (about 500 miles), and supplied radar images of many ocean features, including sea ice, currents, eddies, and internal waves.
