NISAR, the most powerful satellite in human history, will be launched early next year. This satellite has been jointly developed by the Indian space agency ISRO and the American space agency NASA. This satellite alone can provide information about any kind of disaster occurring around the world.
This spy deployed in space will keep an eye on earthquakes, landslides, forest fires, rains, cyclones, storms, lightning, volcanic eruptions, movement of tectonic plates… everything. This will alert you to these natural events before they occur.
After the launch of NASA-ISRO Synthetic Aperture Radar (NISAR), it will give the whole world the first information about upcoming earthquakes. NISAR will be able to record the movement of tectonic plates down to the centimeter level. More or less movement will determine where and when an earthquake may occur. It will take 12 days to revolve around the Earth.
What will Nisar satellite look like in space?
The NISAR satellite will have a large main bus, which will house many instruments. It will have transponder, telescope and radar system. An arm will emerge from it on which there will be a cylinder. When this cylinder opens a few hours after launch, a big umbrella like dish antenna will emerge from it. The umbrella itself is a synthetic aperture radar.
A new Earth report will be available every 12 days
NISAR applications lead Kathleen Jones said NISAR would hold another round in 12 days. Changes occurring on the earth's surface over a period of so many days can be known. You can also know what kind of weather is prevailing in which country or what kind of natural disaster is likely to occur.
Where will it be launched from?
The satellite will be launched by GSLV-MK2 rocket. This launch will take place from the second launch pad of Satish Dhawan Space Center in Sriharikota. The satellites and payloads have been tested several times.
What will Nisar do?
This satellite will save the world from natural disasters. The world's most expensive Earth observation satellite. Rs 10 thousand crores have been spent in making it.
Not only will a city collapse, but there will also be warnings of many disasters, including tornadoes, hurricanes, volcanoes, earthquakes, melting glaciers, sea storms, wildfires, sea level rise, etc.
NISAR will also provide information about space debris around Earth and threats to Earth from space.
How will this work?
NISAR will have two types of bands L and S. Both will monitor the growth and decline of vegetation on Earth and will also study the effects of lack and excess of light. The S band transmitter is made by India and the L band transponder is made by NASA.
One revolution of the earth in 12 days
Nisar's radar will be capable of capturing clear images of an area up to 240 km. It will again photograph the Earth from space after 12 days. Because it will take 12 days to complete one revolution of the Earth. The life of this mission is considered to be 5 years. However, it may increase.
