The Indian Space Research Organization (ISRO) reported on Sunday (July 27, 2025) that the first Earth Overview satellite (NISAR), created by Space Agencies, India and America, ISRO and NASA, will now be launched on 30 July. This satellite will monitor the changes on the surface of the earth, sea, snow and forests.

NISAR Mission launch date and place

NISAR will be launched from the Satish Dhawan Space Center in Sriharikota, Andhra Pradesh via GSLV-F16 rocket at 5:40 pm.

What is NISAR Mission?

NISAR (NASA-Isro Syntic Aperture Radar) is an advanced satellite mission that is developed by ISRO and NASA. This satellite will help accurately measure changes in the Earth’s surface, snow, forest and oceans. This satellite will be able to take a picture of the entire earth every 12 days, which will be able to study important aspects like scientific climate change, earthquake, volcano, landslides and melting of glacier. Its data will also be used in farming, disaster management and environmental protection. After the launch, 90 days will be spent in the setup, then it will start work.

What is the purpose of NISAR Mission?

1. Measuring the movement of land and ice.

2. Understanding changes in crops and forests.

3. To study snow from Himalayas, Greenland and Antarctica.

4. Earthquake, volcano, landslide and analysis of changes in groundwater levels

Increased responsibility of both countries

1. ISRO has prepared S-Band radar, satellite structure, data system and launch.

2. NASA has made a 9 meter boom for L-Band radar, GPS receiver, solid-state recorder and 12 meter wide reflector.

3. After the launch, the first 90 days will be called ‘Commissioning Phase’, in which all the equipment will be tested and set.

What is the importance of NISAR mission

According to ISRO, this mission will prove to be a milestone in the Earth’s monitoring technology. Scientists will get data of two different radar techniques from the same platform, so that changes related to environment and climate will be better understood.
