NASA Launches International Mission \u2018SWOT\u2019 to Survey Earth\u2019s Water:<\/strong> The\u00a0US National Aeronautics and Space Administration (NASA)\u00a0and the\u00a0French space agency Centre National d\u2019Etudes Spatiales (CNES)\u00a0have jointly launched the newest\u00a0Surface Water and Ocean Topography (SWOT) spacecraft\u00a0to track nearly all the water on the surface of the Earth. It was launched from California’s Vandenberg Space Force Base on top of a SpaceX rocket from Space Launch Complex 4E. It will remain operational for 3 years.<\/p>\n\n\n\n

About SWOT mission:<\/strong><\/p>\n\n\n\n

The Surface Water and Ocean Topography (SWOT) mission is a satellite altimeter that was collaboratively created and is currently being used by NASA, CNES (the French space agency), the UK Space Agency, and the Canadian Space Agency.The mission\u2019s objective is to make the world\u2019s first-ever global survey of the Earth\u2019s surface water, capable of observing the finer details of the ocean surface topography and measuring the changes in the terrestrial surface water bodies. As it uses wide-swath of altimetry technology, the mission will be capable of almost completely observing the world\u2019s oceans and freshwater bodies with repeated high-resolution elevation measurements.<\/p>\n\n\n\n

It will provide the first truly global observation of the changes in water levels, stream slopes and inundation extents in rivers, lakes and floodplains. The satellite can measure the height of water in freshwater bodies and the ocean on more than 90 percent of the Earth\u2019s surface. It can also observe ocean circulation at unprecedented scales of 15 to 25 km, which is an order of magnitude that is finer than current satellites. The information obtained from this mission can be used to understand the ocean\u2019s influence in climate change, impact of global warming on the waterbodies, and the preparedness of communities for disasters like floods and droughts.<\/p>\n\n\n\n

The satellite will start collecting data in around six months after undergoing a series of checks and calibrations. Once operational, it will at least once every 21 days cover the whole Earth’s surface between 78 degrees south and 78 degrees north latitude. It will send back some 1 terabyte of unprocessed data each day. It is equipped with an instrument called the Ka-band radar interferometer (KaRIn), which bounces radar pulses off the surface of the water and receives the return signal using 2 antennas on either side of the spacecraft.<\/p>\n\n\n\n

National Aeronautics and Space Administration (NASA):<\/strong><\/p>\n\n\n\n

It is an American government\u2019s premier space agency which was set up in 1958 to promote research and development in the exploration of outer space and Earth\u2019s atmosphere. NASA mainly launches its rockets from its two primary spaceports. One is John F. Kennedy Space Center on Merritt Island in Florida, United States and from Vandenberg Space Force Base in California, United States of America.<\/p>\n\n\n\n
