ISRO-NASA's NISAR: A New Earth Observation Satellite Ready to Launch
Imagine a super-powered eye in space, called NISAR, that can see tiny changes on Earth's surface, even through clouds!
It's a collaboration between India and the US.
This expensive satellite will use radar to watch how the ground, ice, and forests are changing.
Scientists will use the data to better understand natural disasters like earthquakes and landslides, helping us prepare for them.
It also helps monitor human-made structures like dams and bridges.
NISAR has two special radar systems, allowing it to see details about all sorts of environments all over the world.
NISAR, a joint ISRO-NASA Earth observation satellite, is scheduled to launch on July 30.
The satellite will use advanced radar to monitor changes in Earth's surface, including land, ice, and ecosystems.
NISAR's data will aid in understanding natural disasters like earthquakes and landslides and monitoring human-made structures.
It features dual radar systems (L-band and S-band) to provide detailed information about Earth's surface.
The satellite is the most expensive Earth observation satellite to date, costing $1.5 billion.
