ISRO-NASA NISAR Satellite Deploys Antenna in Space
Imagine a giant eye in space, called NISAR, built by India and the US.
This eye has a huge antenna and will watch Earth very closely.
It's like having a super-powered camera that can see tiny changes on the ground, even through clouds!
Launched in July, it cost a lot of money.
Scientists will use it to study things like melting ice and help predict natural disasters.
The data will be available in a few months, helping us understand and protect our planet.
NISAR, a joint mission by ISRO and NASA, successfully deployed its 39-foot antenna reflector.
Launched on July 30, NISAR is the most expensive Earth observation satellite, costing $1.3 billion.
The satellite will track changes in Earth's solid, liquid, and frozen landforms.
NISAR is equipped with dual radar systems for all-weather imaging.
Data from NISAR is expected to be available in mid-October.
