NISAR- Joint mission of ISRO and NASA

Nisar
Joint mission of ISRO and NASA

NISAR: The New satellite on a mission, for which ISRO and NASA are collaborating. This will be a joint mission of ISRO and NASA. The satellite will detect movements of the planet’s surface, as small as 0.4 inches. It is almost half the size of the tennis court. 

The launch date of the satellite will be 2022. Further, it will take off from Satish Dhawan Space Center in Sriharikota, India. Moreover, near-polar orbits and will be able to scan the globe every 12 days in its 3 -year-mission. This will image Earth’s Land, ice sheets, and sea ice to give an unequaled picture and look of our Planet.

What actually NISAR is?

A satellite of SUV size, which the agencies of the USA and India will develop.As the ISRO and NASA signed an agreement in September 2014. Moreover, as per the agreement, NASA will provide radars for the satellite, a high-rate communication subsystem for science data, GPS receivers, and payload data subsystem. ISRO will be providing a spacecraft bus and will be providing second or other types of radar ( S-band radar). Along with the vehicle launch, and other services related to launching. 

According To The Reports :

Meanwhile, NISAR will have the largest reflector antenna ever launched by NASA. The primary goal of this joint mission of ISRO and Nasa, the satellite is to track the subtle changes in Earth’s surface. Such as volcanic signs and warnings, monitor groundwater supplies, and also trekking rate of ice sheets melting. 

NISAR is the short name for NASA-ISRO-SAR. SAR is the synthetic radar that NASA will use to measure changes in the surface of Earth. SAR is basically a technique that produces high-resolution images. The radar can also penetrate clouds and darkness because of its precision, that is it can collect data in any weather.

In these 3 years, it will allow scientists to note changes in croplands, hazards and to measure and monitor volcanic eruptions. Moreover, the image that satellite will show will be able to show local changes. It will be broad enough to measure to show all regional trends. Also, this data will help us in better understanding the causes and consequences of land surface changes. This will help us to manage our resources in a meaningful way.

These images will capture changes in Earth due to certain activities. If too much water is drawn from the underground aquifer then ground can begin to sink, which scientists aim to capture.

“NISAR is an all-weather satellite that’s going to give us an unprecedented ability to look at how Earth’s surface is changing,”

Paul Rosen, NISAR project scientist at JPL

In short, this joint mission of NASA and ISRO will definitely be a boon.
