On December 17, 2020, the Indian Space Research Organisation (ISRO) successfully launched the Polar Satellite Launch Vehicle (PSLV) C-50 carrying its 42nd communication satellite designated as CMS-01. This mission had been scheduled for December 7 this year, exactly a month after the successful launch of the PSLV C-49 that carried ISRO’s all-weather Earth Observation Satellite along with nine other satellites belonging to other nations. However, on account of adverse weather conditions, the launch was postponed by ten days. The Polar Satellite Launch Vehicle (PSLV) C-50 in its XL configuration with six solid strap-on motors carrying the communication satellite, lifted off from the Second Launch Pad of Satish Dhawan Space Centre (SDSC) at Sriharikota. This was the 52nd flight of the PSLV, a highly successful workhorse designed and developed by ISRO and was the 77th launch vehicle mission from this location.
