ISRO & NASA Finalize Joint NISAR Earth Observatory: Dual-Radar Satellite Set for Launch
EXECUTIVE 60-SECOND BRIEFING
- Dual-Radar Capability: First satellite to integrate both L-Band (ISRO) and S-Band (NASA) Synthetic Aperture Radars.
- Sub-Centimeter Precision: Capable of measuring tectonic surface shifts down to fractions of an inch.
- 12-Day Planet Sweep: Comprehensive surface scan of the entire globe every 288 hours.
SRIHARIKOTA — Scientists and aerospace engineers at the Satish Dhawan Space Centre have officially certified the flight readiness of the NASA-ISRO Synthetic Aperture Radar (NISAR) spacecraft, marking the culmination of a decade of groundbreaking bilateral cooperation in space science.
Weighing approximately 2,800 kilograms, the observatory will be injected into a 747-kilometer Sun-synchronous orbit via ISRO’s battle-tested GSLV Mark II launcher. Unlike standard optical imaging satellites that are blind to cloud cover or nighttime conditions, NISAR’s dual sweep radars penetrate dense cloud layers, forest canopies, and ice shelves with unyielding radar interferometry.
