The PSLV-C53/DS-EO mission has been successfully accomplished, said Indian Space Research Organisation on Thursday.The launch was scheduled for 6 PM from the Second Launch Pad at Satish Dhawan Space, Sriharikota, added ISRO.The countdown of 25 hours leading to the launch started at 5 PM on Wednesday.PSLV-C53 is the second dedicated commercial mission of NewSpace India Limited (NSIL). It is designed to orbit the DS-EO satellites along with two other co-passenger satellites from Singapore.This is the 55th mission of PSLV and the 15th mission using the PSLV-Core Alone variant. It is the 16th PSLV launch from the second launch pad.The mission proposes to demonstrate the utilisation of the spent upper stage of the launch vehicle as a stabilized platform for scientific payloads subsequent to the separation of the satellites.Digantara, a spacetech startup, said that the “world’s first commercial space-based space weather system”, ROBI (ROBust Integrating proton fluence meter), designed by it was also launched onboard ISRO’s PSLV-C53 Mission.With the launch of the world’s smallest digital space weather sensor for monitoring space weather, the company has taken a giant leap towards building their space infrastructure for providing a one-stop comprehensive space situational awareness solution, it said.Noting that space weather is a complex phenomenon that arises from high energy particles, plasma, and electromagnetic waves originating from the sun or the cosmos interacting with the earth’s magnetic field, Digantara said, a major space weather event can have significant repercussions on both space and terrestrial systems.
