ISRO’s PSLV-C51 Launch Mission | PSLV-C51/Amazonia-1 Mission

PSLV-C51’s main excitement was carrying a satellite from Pixxel India, but a week before the launch, the company stated that due to “certain software issues” during testing, their satellite would not go with the launch. Still, ISRO’s PSLV-C51 Launch mission is a great achievement for India.

PSLV-C51 is India’s first launch of 2021 and 78th Launch Vehicle Mission from Satish Dhawan Space Centre (SDSC) SHAR.

PSLV-C51 is the 53rd mission of PSLV, and it launched Amazonia-1 of Brazil as primary satellite and 18 Co-passenger Satellites from SDSC SHAR, Sriharikota.
