New Delhi. The satellite ‘NISAR’ (NISAR) made successfully launched on Wednesday (NISAR) on Wednesday. It was sent to space from the Satish Dhawan Space Center in Andhra Pradesh via GSLV-F16 rocket. It is the world’s most expensive Earth Scanner Mission ever, which is said to be about $ 1.5 billion i.e. about Rs 12,500 crore.

After a 19 -minute flight, the Nisar satellite was installed in the Sun synchronous polar orbit (SSPO). The special thing is that this was the first time that the GSLV rocket was sent to SSPO orbit, otherwise all its missions were limited to only GTO (Geocyncronus transfer orbit).

Why is Nisar special?
Nisar is a satellite that can scan the Earth every season and at all times. It will scan the surface of the entire Earth every 12 days. It has two special radars-ISRO S-band and L-band of NASA, which make it the world’s first dual-frequency radar satellite. It will monitor earthquakes, landslides, melting of glaciers, changes happening in forests, fields and mountains.

What will be the benefit?
This will give scientists 3D pictures of changes in the surface of the Earth. This will help in identifying and forecasting disasters. Policy makers and governments will get great support in disaster management and planning. This data will be extremely useful in areas like agriculture, environment, climate change.

Strong partnership of Indo-US
This mission is considered an example of the scientific friendship of ISRO and NASA. NASA’s Deputy-Ser-Principal KC Wishers called it “a brilliant decade of technical cooperation and cultural understanding”. At the same time, ISRO chief V. Narayanan described it as a historic achievement in the space field of India.

The lifetime of Nisar Mission is 5 years. Its operation will be ISRO and will plan radar operating NASA. The two agencies will convey the data available to scientists.
