Why is the 'superhero' of the Earth nisar satellite of Isro-Nasa called? Know the tremendous features of that

On July 30, 2025, India will again create history in space. Nisar (Nasa-Isro synthic opening radar) satellite, made by Isro and Nasa. The GSLV-F16 rocket will be introduced from the Saath Dhawan Space Center in Sriharikota. This satellite watches every small and large act of the earth clouds, darkness or bush. Farmers, scientists and disaster relief teams are satellite games for everyone. What is nisar? Nisar is a satellite to monitor the earth, which results in the result of the partnership of NASA (America) and Isro (India). The full name is the Nasa-esro-synthetic diaphragm radar. It is the first such satellite in the world, which will use double frequency radar (L-band and S-band). This means that it scans the earth’s surface with two different types of radio waves, which give many accurate photos. Weight: 2,392 kg Introduction: July 30, 2025, IT at 17:30 of GSLV-F16 Rocket. Missionary period: At least 3 years, in which every 12 days will make a map of the whole world. Height: 743 km Sun-Cinnamon will be in orbit, that is, it will constantly work in sunlight. Cost: About 1.5 billion (about 1.25 lakh crore rupees), making it the world’s most expensive meaning -observing satellite. Nisar’s 12 -meter maasantens (like large umbrella) and Sweepsar technology give it the power to scan the 242 km wide area. It can take photos with an accuracy of 5-10 meters. Catch as small as 1 inch. How does Nisar work? Nisar has synthetic diaphragm (SAR) technology, which makes photos of radio waves. It differs from normal cameras, because … no effect of clouds, fog or night: it can see outside clouds and darkness. 24/7 Work: Day and Night, collect data in each season. Double Radar L-Band (NASA): Look up to the dense forests and underground. Best to monitor earthquakes, volcanoes and ice. S-band (isro): Give soil moisture and crops. Sweepsar: This technique is used for the first time, scanning large areas in high resolution. What will Nisar do? Nisar will watch everything on earth. Its most important functions are … Monitoring of natural disasters Earthquake: will detect the movement of tectonic plates on centimeters. Volcano: Will interact with each other in advance with the actions of Lava. Landslides and tsunamis: Warning of danger in the Himalayas or coastal areas in advance. Glaciers and climate change snow: Himalayas and Antarctica will show the velocity of melting ice, which will predict the rise in sea level. Jungle: Will monitor the state of deforestation and vegetation. Again: Will provide information on soil moisture and water resources.
