## Editorial
RISAT-2BR1 is an ISRO radar imaging Earth observation satellite in the RISAT programme, launched on 11 December 2019 aboard PSLV-C48 from Sriharikota.[^isro-pslv-c48] The satellite carries an X-band SAR-X synthetic aperture radar operating at 9.59 GHz, delivering 1 to 8 m spatial resolution across 10 to 50 km swath widths depending on imaging mode.[^wmo-sar-x-risat] The mission operates in a low Earth drifting orbit; ISRO recorded an injection orbit of 576 km while WMO OSCAR notes a later operational altitude of approximately 555 km, both at 37 degree inclination.[^isro-pslv-c48][^wmo-risat-2br1] WMO records the satellite as operational as of a February 2026 update,[^wmo-risat-2br1] beyond the 5-year design life stated at launch.[^isro-pslv-c48] Mass was reported as 628 kg by ISRO and 615 kg by WMO OSCAR.[^isro-pslv-c48][^wmo-risat-2br1] Applications include agriculture monitoring, forestry assessment, disaster management, and reconnaissance, with data distributed offline through NRSC and received at appointed ground stations.[^isro-pslv-c48][^wmo-risat-2br1]
