World's most advanced and expensive satellite to launch soon

The NASA-ISRO Synthetic Aperture Radar (NISAR) satellite is set to be launched in March 2025 from the Satish Dhawan Space Centre on India's southeastern coast.

This satellite is a collaborative effort between NASA and ISRO, and it's considered the world's most advanced and expensive Earth observation satellite.

Key Features:

 Dual-Frequency Radar: NISAR will use NASA's L-band (1.25 GHz) and ISRO's S-band (3.20 GHz) radars, providing unprecedented data accuracy.

Global Coverage: 

It will scan nearly all of Earth's land and ice surfaces twice every 12 days, helping scientists monitor changes in ecosystems, land and sea ice, and the solid Earth.

Disaster Management: 

NISAR will provide valuable data for disaster response, assessing damage before and after disasters.
