Is SeaSat still in orbit?
But this spunky satellite, which is still in orbit, shining in the night sky at magnitude 4.0, continues to live on through the many Earth and space observation missions it has spawned.
What did SeaSat do?
One of the earliest Earth-observing satellites, Seasat was designed to test various oceanographic sensors and gain a better understanding of Earth’s seas.
What is SeaSat 1?
Seasat was the first satellite designed for remote sensing of the Earth’s oceans with synthetic aperture radar (SAR). Specific objectives were to collect data on sea-surface winds, sea-surface temperatures, wave heights, internal waves, atmospheric water, sea ice features, and ocean topography.
What happened to SeaSat?
Although Seasat ceased data transmission on October 10, 1978, as a result of a power failure, it achieved its primary purpose: to demonstrate that much useful information about oceanographic phenomena could be obtained by means of satellite surveillance.
What did SeaSat discover?
Seasat Rediscovered: ASF DAAC Imagery from 1978 Data. Launched by NASA in 1978, the Seasat satellite’s primary mission was to observe oceans using NASA’s first synthetic aperture radar (SAR) sensor. SAR bounces a microwave radar signal off the surface of Earth to detect physical properties.

What is SeaSat used to measure?
Radar Altimeter (ALT) – used to measure wave heights by measuring spacecraft altitude above the ocean surface. The experiment operated at Ku-band and had 10 cm vertical accuracy. Seasat-A Satellite Scatterometer (SASS) – used to measure wind speed and direction.

What was the purpose of the Seasat program?
The SeaSat program had three main objectives: 2) to provide timely oceanographic data to scientists studying marine phenomena, and to users of the oceans as a resource (ocean shippers, fishermen, marine geologists, etc.) 3) to determine the key features of an operational full-time ocean-monitoring system.
What is Seasat’s SAR?
SeaSat’s SAR instrument provided spectacular images of Earth’s land surfaces, thus demonstrating the immense potential of the SAR observation technology and generating great interest in satellite active microwave remote sensing. SeaSat carried five other instruments designed to return the maximum information from ocean surfaces:
Where can I find Seasat data?
SeaSat data is freely and openly available to everyone. On board SeaSat was the first-ever space-borne synthetic aperture radar (SAR) system for science applications. SeaSat was a NASA oceanography experimental mission. It was launched on 28 June 1978 and ceased operations that same year.
What happened to Seasat?
– After the early failure of the satellite, funds programmed for satellite operations were reprogrammed by W. Stanley Wilson to fund a SeaSat Data Utilization Project. SeaSat managers, with advice from scientists, released data to all with a demonstrated interest in evaluating data.
