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.
