The first space partnership between India and the United States began on Wednesday, when the Indian Space Research Organization (ISRO) successfully sent the satellite of the name ‘Nisar’ into space. The satellite has been created by ISRO and American space agency NASA. It was launched from the Satish Dhawan Space Center in Sriharikota via ISRO’s GSLV F-16 rocket at 5:40 pm.
About 19 minutes after the launch, the rocket successfully installed ‘Nisar’ in a special class (Surya synchronized polar orbit). ‘Nisar’ is an observation satellite, which will monitor things such as earthquakes, landslides, snowfall and changes in forests. This mission is considered to be an example of technical cooperation between India and the US.

Earlier on May 18, ISRO’s PSLV-C61 mission was unsuccessful, in which a satellite monitoring Earth could not reach the fixed orbit. However, ISRO has earlier successfully launched many satellites such as Resourcesat and Recyat, especially created for India’s needs. But through the ‘Nisar’ mission, ISRO has now taken a big step towards keeping an eye on the entire earth and gathering scientific information.
After a countdown of about 27 hours, the 51.7 meter high GSLV F-16 rocket was launched from Satish Dhawan Space Center, Sriharikota at 5:40 pm on Wednesday. This rocket had a ‘Nisar’ satellite weighing 2,393 kg. After the separation of the satellite from the rocket, scientists have started the process of completely activating it, which will last for the next few days. After this process, the satellite will be ready to fulfill the purpose of its mission.
ISRO informed that India has developed S-Band radar system, data handling system, high-speed downlink system, satellite and launch system for Nisar Mission. At the same time, US space agency NASA has provided L-Band radar system, high-speed data recorder, GPS receiver, 9 meter long boom and 12 meter radar reflectors for this mission.

ISRO will take responsibility for the operation and direction of this satellite, while NASA will tell the plan to run the satellite in class and operate radar. Both agencies will download the data received through the ground station and process it and reach the users. With the help of S-Band and L-Band radar data received from the same platform, scientists will be able to better understand the changes in the Earth. According to ISRO, the main objective of Nisar Mission is to change the surface of the ground and ice, to study the ecosystem of the ground and the marine areas. This mission will help in assessing the structure of the forests, changes in the crop area, the range of wetlands (wetlands) and the amount of organic materials. The duration of Nisar Mission will be five years.
NASA said that data from Nisar Mission will help predict the dangers caused by natural and human reasons and can give governments enough time to take decisions. This satellite will provide three-dimensional views of the earth’s land and snow surface and will be able to send data day and night despite clouds and light rain. This will lead to continuous monitoring of earthquake and landslide potential areas and also assess the changes in glaciers.

This satellite will also give unprecedented data to Antarctica, which will help to understand how the snow sheets are changing over time. Nisar is the most advanced radar system ever launched by NASA and ISRO and it will generate more data than any Earth satellite every day before. This mission will help both countries monitor the global ecosystem. The L-Band radar will reach the depth of the forests and inform about their structure, while the S-band radar will monitor crops. From the data obtained from Nisar, researchers will be able to know how the forest, wetland and agricultural sectors are changing over time.
