The last sunrise of February brings joy and excitement. People of India and Brazil begin the new day awaiting the launch of PSLV-C51 which carries 19 satellites (1 from Brazil and 12 from the U.S.A). This is the Indian Space Research Organization’s first launch mission of 2021. At around 10:25 AM (IST), Polar Satellite Launching Vehicle (PSLV) lifted off from the first launchpad of Satish Dhawan Space Centre (Sriharikota Range) after a 25.5-hour countdown. Amazonia-1 is the primary satellite of this launch and it is expected to be injected into orbit about 18 minutes after lift-off. It is the first Earth observation satellite entirely developed by Brazil.

At 10:42 AM (IST), Amazonia-1 was successfully separated from fourth stage of PSLV and was injected into orbit.

At 10:44 AM (IST), Upper Stage Engines scheduled to restart twice for the rocket to reach a lower orbit to inject the remaining 18 satellites.

At 12:33 PM (IST), Indian Space Research Organization (ISRO) tweeted:

The mission lasted for two hours and eight minutes. It was the 53rd flight of PSLV-C51 and is counted in one of its longest journeys.

Marcos Ceaser Pontes, Minister for Science, Technology and Innovation, Brazil in his address at the launch event said:

“We have been working on this satellite for many years. This satellite which was launched today has a very important mission for Brazil. It will monitor the deforestation in the Amazon region and analysis of diversified agriculture across the Brazilian territory.”
