First Brazilian satellite, Amazônia-1 is launched into space


The first 100% Brazilian satellite, Amazônia-1, was successfully launched into space at dawn on Sunday (28), transported to Earth orbit by the Indian rocket PSLV-51. The satellite left the Satish Dhawan Space Center in Sriharioka Andhra Pradresh, India, at 1:54 am (GMT).

Currently, two other Brazilian remote sensing satellites are already operating in space: CBERS-4 and CBERS-04A, launched in 2014 and 2019, respectively. Unlike Amazonia -1, however, both space exploration equipment was developed in partnership with China, in a proportion of 50% for each country.

"Amazônia-1 is the first exclusively Brazilian satellite, having been entirely conceived, designed, developed, integrated, tested, and soon, operated by Brazil", says the substitute director of Inpe (National Institute for Space Research), Mônica Rocha .

"The importance of the feat goes through two main issues: Brazil's ability to carry out an important task in a completely autonomous way and to master the complete production cycle of a satellite of this size - 640 kilos and 2.5 m high -, which puts the country in a group of less than 20 countries with this competence ", he adds.

This includes integrating, testing and monitoring the launch, carrying out the initial maneuvers to position the Amazonia-1 in the correct orbit, verifying the proper functioning of all equipment and subsystems, carrying out the operation during the life of the satellite - which is at least four years - and, finally, promote its removal from orbit, at the end of the mission.

The important task of the new satellite is to monitor deforestation in the Amazon region and the development of agriculture throughout the national territory. For this, the space exploration equipment will be placed in a sun-synchronous orbit - that is, which allows successive passages over the same point on Earth at the same solar time - at a height of 760km and will cross the Equator in the North- South at 10:30 am local time, traveling at a speed of almost 27,000 kilometers per hour.

At this speed, the satellite will take just a hundred minutes to take a spin on Earth, allowing it to take images from anywhere on the planet every five days. Together, CBERS-4 and CBERS-04A will promote recurring images of Brazilian territory every two or three days.
