NASA’s SWOT Satellite will survey all the Sources of Water on Earth.
The first satellite was launched on Friday to survey all the sources of water on Earth. It has been prepared jointly by the American Space Agency NASA and the French Space Agency National Center for Special Studies. The name of this satellite is International Surface Water and Ocean Topography (SWOT). It was sent into space via SpaceX’s Falcon 9 rocket.
Will help in water related disasters
According to the researchers associated with the mission, with the help of information obtained from SWOT, we will be able to avoid water-related disasters in future. Nowadays incidents like floods and cyclones have increased, due to which people all over the world are getting affected. This is part of climate change. Significantly, changes in the atmosphere and weather occur only with water. In such a situation, it is very important to do research on this.
Will catch things 10 times smaller than satellite
SWOT has an instrument called the Ka-band Radar Interferometer (KaRIn), which NASA has been building for years. It will capture water features 10 times more closely than ocean floor satellites. With this, scientists will be able to study the properties of ponds, rivers and seas in detail. For example- Normal satellites can collect data of only a few thousand ponds in the world, but SWOT will give information about more than 1 million ponds.
Satellite will investigate even in the dark of night
NASA said that two antennas fitted in KaRIn send radar pulses to the surface of the water and receive the signal back. They will be able to collect data even when the night is dark and cloudy. According to scientists, for the first time rivers larger than 330 feet can be seen in 3D and the area of less than 100 kilometers of seas can be measured.
