Rank 35 documents RISAT-1 — India's first indigenous radar imaging satellite, launched 26 April 2012 aboard PSLV-XL from Sriharikota. The 1,858-kilogramne bus carries a C-band synthetic aperture radar that penetrates cloud cover, darkness, and rain — enabling all-weather disaster monitoring, agricultural assessment, and soil-moisture mapping across the Indian subcontinent. RISAT-1's SAR panel generates microwave imagery that optical Earth observation satellites cannot produce during monsoon seasons, making it a critical asset for flood response, cyclone tracking, and national resource management. Wallimilist renders the SAR antenna panel with downward microwave beam through monsoon clouds, PSLV pad tower background, split-manifesto cream-navy layout with RISAT-1 slab title, FIRST INDIAN SAR SATELLITE kicker, and RADAR SEES THROUGH CLOUDS footer exactly as the master PNG dictates — ISRO and PSLV emblems, specimen data bands, and curator copy on Indian radar Earth observation heritage.
