New Delhi: The Indian Space Research Organization (ISRO) and the US Space Agency (NASA) together are about to launch a satellite worth $ 1.5 billion in 2022. NASA needed a special S-band synthetic aperture radar (SAR) for this satellite that India has made available. With this, the important link to complete this SUV-shaped satellite was added.
Significantly, the largest reflector antenna has been installed in this satellite so far. The interesting thing is that the rocket of ISRO which will carry this satellite was banned by the US in 1992. The NASA-ISRO SAR (NISAR) weighing 2200 kg is considered the world’s most expensive imaging satellite and is being built at NASA’s Jet Propulsion Laboratory in California.
What did NASA say
NISAR, melting of volcanoes, ice sheets on the surface of the Earth and changes in sea level and changes in the condition of trees and forests around the world will be tracked. NASA has said in a statement, “Monitoring of such changes on the Earth’s surface has never been done in such a high resolution and space-time.”
Up to 0.4 inch accurate
A 40-foot wire mesh radar reflector antenna will be used in this satellite, which will be mounted on a 30-foot boom. With this, radar signals will be sent and received from the surface of the earth. NISAR will scan the entire earth every 12 days and it can detect up to 0.4 inch movement in half of a tennis court. Let us tell you that this will be the first satellite mission that will use two different radar frequencies and will be able to name the change occurring up to one centimeter away on the surface of the Earth.
High resolution radar
This high resolution radar will also be able to see through clouds and dense forest. This ability will lead to success in both day and night missions. Apart from this, it can track any change, rain or shine. Let us tell you that the United States and India had signed this agreement in 2014. At that time, former US President George Bush banned ISRO in 1992 and prevented Russia from providing cryogenic engine technology with Delhi. The US was afraid that India would use it to make long-range missiles. Now this satellite will be launched with the same Geosynchronous Satellite Launch Vehicle rocket.
