Context
-
The NASA-ISRO Artificial Aperture Radar (NISAR) satellite tv for pc is scheduled for launch at 5:40 p.m. on Wednesday from Satish Dhawan Area Centre, Sriharikota.
-
The satellite tv for pc has been mounted on the GSLV-F16 (Geosynchronous Satellite tv for pc Launch Car), and all programs have been checked by ISRO.
Satellite tv for pc Specs
-
Weight: 2,392 kg
-
Orbit: 743-km sun-synchronous orbit – ensures constant Earth statement below related lighting situations.
-
Liftoff Web site: Second Launch Pad, Sriharikota.
Key Expertise – Twin-Frequency SAR
-
First satellite tv for pc to make use of dual-frequency Artificial Aperture Radar (SAR):
-
L-band SAR (NASA)
-
S-band SAR (ISRO)
-
-
Makes use of NASA’s 12-metre unfurlable mesh reflector antenna, mounted on ISRO’s modified I3K bus.

Conclusion
NISAR is a landmark Indo-U.S. collaboration, combining NASA’s radar experience with ISRO’s launch functionality. With high-resolution dual-band SAR and extensive protection, it is going to improve Earth statement for local weather monitoring, catastrophe administration, and useful resource mapping. Its data-driven insights shall be essential for addressing local weather change, pure hazards, and sustainable growth objectives (SDGs).
