PSLV-C51

ISRO successfully launched Brazil’s optical earth observation satellite, Amazonia-1, and 18 co-passenger satellites from India and the U.S.A. from the Satish Dhawan Space Centre (SHAR) at Sriharikota on board the PSLV-C51

The satellites were carried on board the PSLV-C51, the 53rd flight of India’s workhorse launch vehicle and the first dedicated mission for New Space India Ltd (NSIL), the commercial arm of ISRO.
Of the satellites launched, five satellites belong to India including the Satish Dhawan SAT (SDSAT) built by Space Kidz India, a nano-satellite intended to study the radiation levels, space weather and demonstrate long range communication technologies, and the UNITYsat, a combination of three satellites intended for providing radio relay services.
The SDSAT developed by SpaceKids India has an engraving of Prime Minister Narendra Modi on the top panel of the satellite to show solidarity and gratitude for the Atmanirbhar initiative and space privatisation.
The Bhagavad Gita was also sent on-board an SD card to give the scripture, which teaches oneness as the highest form of humanity, the highest honour.

Amazonia-1, belonging to the Brazilian National Institute for Space Research (INPE), was launched by the PSLV.
Amazonia-1 is the first fully Brazilian-made satellite, which would help to monitor the Amazon forests.
The satellite will further strengthen the existing structure by providing remote sensing data to users for monitoring deforestation in the Amazon region and for analysis of diversified agriculture across the Brazilian territory.
The Amazonia-1 was injected in a sun-synchronous polar orbit. A Sun-synchronous orbit (SSO), also called a heliosynchronous orbit, is a nearly polar orbit around a planet, in which the satellite passes over any given point of the planet’s surface at the same local mean solar time.

PSLV-C51 is the 53rd mission of the Indian Polar Satellite Launch Vehicle (PSLV) program.
Polar Satellite Launch Vehicle (PSLV) is the third generation launch vehicle of India.
It is a four-staged launch vehicle with first and third stage using solid rocket motors and second and fourth stages using liquid rocket engines.
It is the first Indian launch vehicle to be equipped with liquid stages.

It is 700 verse Hindu scripture in Sanskrit that is part of Hindu epic Mahabharata.
It is set in the narrative framework of dialogue between Pandava prince Arjuna and his guide and charioteer Lord Krishna.
The Bhagavad Gita presents a synthesis of the concept of Dharma, theistic bhakti, yogic ideals of moksha through jnana, bhakti, karma, and Raja Yoga and Samkhya philosophy.

Bhagwad Gita also emphasizes virtues that are indispensable for righteous administration.
Virtues such as an unagitated mind(anuvignamanas), firm mindedness( prajna pratisthita), disinterestedness( anapeksas, udasinas), contentment with one’s own duty( svakramaniratas), indifference to pleasure and pain( samaduhkhasusukhas), being the same towards friend and enemy(samah satrau cha mitre cha) to perform his/her own most ethical manner.
Gita implies that administrators occupying their position should discharge their duty. It also desires an administrator to be a combination of a raja and rishi, i.e. synthesis of selflessness (without any consideration of personal affection) and saintliness (no consideration of personal gain)
