ISRO's ______ successfully places two Singaporean satellites into orbit on 22nd April 2023.

PSLV-C55

PSLV-A55

PSLV-C50

PSLV-A50

Correct Answer : PSLV-C55

* Indian Space Research Organisations (ISRO) successfully launched the Polar Satellite Launch Vehicle C55 (PSLV-C55) mission carrying two Singaporean satellites from Satish Dhawan Space Center at Sriharikota in Andhra Pradesh on Saturday (22nd April 2023) afternoon.

* PSLV-C55 is a dedicated commercial PSLV mission of NewSpace India Limited (NSIL), which is the commercial arm of ISRO, for an international satellite customer.

* The ISRO said, in a textbook launch, the vehicle placed Singapore’s TeLEOS-2 as the primary satellite and LUMELITE-4 as a co-passenger satellite precisely into their intended 586 km circular orbit.

* It is the 57th flight of PSLV, and the 16th mission of the PSLV Core Alone configuration (PSLV-CA)variant. This is the lightest version of PSLV..
