Paper: GS – III, Subject: Science and Technology, Topic: Space Technology, Issue: NISAR Mission.
Context:
ISRO announced that the NISAR satellite has been mounted on the GSLV-F16 rocket, with all systems checked. The rocket is set to launch from Sriharikota at 5:40 p.m. on Wednesday and will place the satellite into a 743-km sun-synchronous orbit.
Key Highlights of the NISAR Mission:
- The satellite will be launched by the Geosynchronous Satellite Launch Vehicle (GSLV).
- Location: Satish Dhawan Space Centre, Sriharikota GSLV-F16 will place NISAR into a 743 km Sun-synchronous orbit with an inclination of 98.40 degrees.
Technical Specifications:
- The NISAR satellite, weighing 2,392 kg, is a unique Earth observation satellite featuring dual frequency Synthetic Aperture Radar (SAR):
- NASA’s L-band
- ISRO’s S-band Utilizes
- NASA’s 12m unfurlable mesh reflector antenna integrated with ISRO’s modified I3K satellite bus.
About NISARl:
- India and the United States are set to launch their most ambitious joint space mission to date, the NASA-ISRO Synthetic Aperture Radar (NISAR) satellite.Â
- Scheduled for lift-off on July 30 from Sriharikota onboard a GSLV Mk-II, the Rs. 12,000-crore mission has been over a decade in the making and is being considered as one of the world’s most advanced Earth observation missions.
- NISAR will provide real-time, high-resolution radar data on land deformation, biomass, disaster impact, crop patterns, and climate-related changes, not just for India but globally.Â
- It combines NASA’s strength in long-range radar systems with ISRO’s spaceflight engineering and S-band radar technology.
Expected Benefits of NISAR:
Conclusion:
The NISAR mission represents a significant collaboration between NASA and ISRO, promising to deliver valuable data for a wide range of Earth observation applications. The successful launch and operation of NISAR will contribute significantly to our understanding of Earth’s dynamic processes and aid in disaster management and resource monitoring.
