Launching its third rocket of 2019, the India Space Research Organisation (ISRO) sent the RISAT-2B spacecraft into low Earth orbit.
Radar Imaging Satellite 2B is a microwave remote sensing satellite designed to spend five years imaging Earth, providing continuity to services provided by RISAT-2, which launched in 2009. According to ISRO, the 1,355-pound (615-kilogram) spacecraft is the third in the series of India’s radar imaging satellites. It includes an X-band synthetic aperture radar payload, which is designed to resolve features regardless of weather conditions, day or night, and be used for agriculture, forestry and disaster management support.
The 144-foot (44-meter) tall PSLV rocket used for the C46 mission was in a “core alone” configuration, meaning it didn’t have any strap-on solid rocket motors. Liftoff took place at 5:30 a.m. India Standard Time (Midnight GMT) May 22, 2019, from the First Launch Pad at India’s Satish Dhawan Space Centre on the coast of the Bay of Bengal.
