The Indian Space Research Organization (ISRO) and the US Space Agency NASA (NASA) are going to launch a satellite in 2022 that will protect the entire world from natural disasters. That is, we will give information long before disaster strikes. It will be the world’s most expensive Earth Observation Satellite. Its name is NASA-ISRO Synthetic Aperture Radar – NISAR. Its expected cost will be around 10 thousand crores.
NISAR will inform the world of every disaster
After the launch of this satellite, tornadoes, volcanoes, Earth’s crust, earthquakes, glaciers melting, storms, forest fires, decrease in sea level or excess, monsoon can be the kind of disasters you can imagine. It will give information to everyone first. Along with this, it will also periodically inform about the waste accumulating in space and the dangers coming from space to Earth.
NISAR is combined project of NASA AND ISRO
ISRO and NASA together are running a project called Space Situational Awareness. Under this, Nisar (NISAR) will be launched. There will be two types of bands L and S. Both of these will keep an eye on the increasing number of trees and plants on the earth, as well as study the effect of lack of light and getting more.
Its radar will be so powerful that it will be able to take clear pictures of the area up to 240 kilometers. It will take a photo of a place on earth after 12 days. Because it will take 12 days to complete one round of the earth. During this time, it will continue to provide photographs and data to scientists while doing rapid sampling of different parts of the earth.
How NISAR will work
It is believed that after launching this satellite will continue to work for at least 5 years. During this period, subjects such as volcanoes, earthquakes, landslides, forests, farming, wet earth, permafrost, excess snow, etc. will be studied through this NISAR. Also, it will help to save people from such natural disasters.
Five big scientists of ISRO’s Ahmedabad Space Application Center are helping to build this satellite. They will also help in future studies as well. These are Tapan Mishra, Manab Chakraborty, Rajkumar, Anoop Das and Sandeep Ojha. These people will help NASA in studying the natural changes happening in different parts of the earth.
From which rocket this satellite will be launched and from which place. It has not been revealed yet. But it is believed that it will be launched from India’s GSLV-Mark 2 rocket. It is a satellite carrying rocket weighing India.
Nisar (NISAR) satellite will have a large main bus, which will be equipped with many instruments. There will also be many transponders, telescopes and radar systems. Apart from this, an arm will come out of it, on top of which there will be a cylinder. If this cylinder opens a few hours after its launch, then a big umbrella like dish antenna will come out. This umbrella is the only synthetic aperture radar. This will imaging the natural activities happening on the earth.
