NASA-ISRO Nisar Satellite Launched to Monitor Earth
A new satellite called Nisar, made by NASA and India's space agency, is now in space.
It will use radar to watch the Earth and measure tiny changes on land and ice.
This can help scientists predict natural disasters like floods and volcanic eruptions.
The satellite can see through clouds and rain, providing helpful information.
The mission will study things like glaciers and crop growth, potentially helping us understand our planet better.
The NASA-ISRO Nisar satellite was launched to monitor Earth's land and ice regions.
The satellite can detect changes as small as a centimetre.
Nisar will repeatedly bounce radar waves off almost all of Earth's surface.
Data from Nisar could provide early warning of natural disasters like volcanic eruptions and floods.
The mission aims to last three years, with a possibility of extending for a couple more years.
