Indian PSLV rocket launches Brazilian Amazonia-1 satelliteby Andrew — February 28, 2021

The 44-meter-high PSLV-C51 rocket with two solid side boosters
lifted off from the Satish Dhawan Space Center on the Indian island of Sriharikota at 11:54 p.m. Eastern Feb. 28.
The PSLV injected the roughly 700-kilogram Amazonia-1 into its intended Sun-synchronous orbit 17 minutes after launch. The further 18 passengers were released over the subsequent 98 minutes in accordance with a predetermined sequence.
The mission was hailed as the first dedicated commercial mission of NewSpace India Limited (NSIL), a Government of India company under the Department of Space.
Optical Earth observation satellite Amazonia-1 belongs to Brazil’s National Institute for Space Research (INPE). Indian Space Research Organisation (ISRO) chairman K Sivan stated shortly after launch the satellite was in good health.
This satellite is designed to deliver remote sensing data to the government and science community for monitoring deforestation in the Amazon region and analysis of diversified agriculture across the Brazilian territory.
It carries a wide-view optical imager (camera with 3 frequency bands in the visible spectrum – VIS – and 1 band near the infrared – Near Infrared) capable of observing a 850 km range with 64 meters of resolution.
Amazonia-1 is the first Earth observation satellite completely designed, integrated, tested and operated by Brazil. INPE plans to launch two further satellites in the series. INPE of Brazil contracted Spaceflight Inc. to secure the launch.
Its relatively low mass allowed margin for a number of other payloads. Of these 14 were aboard through NSIL, including 12 SpaceBEE 1U-CubeSats for U.S.-based Swarm Technologies, Inc. for two-satellite communications and data relay, and SAI-1 NanoConnect-2, developed by the Space Instrumentation Laboratory of the National University of Mexico. SindhuNetra, an AIS technology demonstrator, was funded by the Defense Research and Development Organization of India.
The four further payloads were for INSPACe, India’s new regulatory and space promotion organization. These were three UNITYsat satellites developed by the Jeppiaar Institute of Technology, G. H. Raisoni College of Engineering, and the Sri Shakthi Institute of Engineering and Technology. The final payload is the 3U-CubeSat Satish Dhawan Sat (
SDSAT) from Space Kidz India to study radiation and the magnetosphere.
ISRO stated that the total number of customer satellites from foreign countries placed in orbit by PSLV is 342 satellites from 34 countries following the PSLV-C51 launch.
The launch is India’s first of a 2021, following a 2020 severely impacted by the COVID-19 pandemic. Satish Dhawan Space Center carried out its first 2020 mission only in November with the launch of the EOS-1 Earth observation satellite and nine smaller payloads. (...)

(...) Amazonia 1 is the first Earth observation satellite completely designed, integrated, tested, and operated by Brazil, according to INPE, a division of Brazil’s Ministry of Science, Technology, Innovation, and Communications. The PSLV aimed to deliver the Amazonia 1 satellite to a 467-mile-high (752-kilometer) sun-synchronous orbit with an inclination of about 98.5 degrees
In that type of orbit, Amazonia 1 will fly over different parts of the world at roughly the same time of day, allowing its imager to observe the environment under similar lighting conditions throughout the satellite’s four-year mission.
ISRO officials confirmed the rocket separated the Brazilian spacecraft into the correct orbit. Officials in the launch control center said Amazonia 1 extended its power-generating solar panels, and ground teams established contact with the new satellite after it arrived in space.
“In this mission, India and ISRO feel extremely proud and honored and happy to launch the first satellite designed, integrated, and operated by Brazil,” said K. Sivan, chairman of the Indian Space Research Organization. “My heartiest congratulations to the Brazilian team for this achievement. The satellite is in very good health, and solar panels are deployed, and it’s functioning very nicely. Let me congratulate and compliment the entire Brazilian team.”
Marcos Pontes, Brazil’s minister of science, technology, innovation, and communications, observed the launch from the Indian space center. In remarks after the launch, Pontes said it was a “very, very happy day.”
“We’ve been working on this satellite for many years, and this moment represents a very important (milestone),” Pontes said. (...)
“The deployment of Amazonia 1 will allow us to capture images and monitor the environment and agriculture throughout the Brazilian territory which will help us better understand the expansive terrestrial environment in the region,” said Adenilson Silva, an INPE engineer managing the Amazonia mission.
The Amazonia 1 satellite is the most advanced spacecraft ever built in Brazil, using the homemade Multi-Mission Platform, or MMP, bus. Although the platform uses parts acquired abroad, the program allows Brazil to gain experience in spacecraft manufacturing, testing, integration, propulsion, and deployment mechanisms, according to INPE.
“In addition to the technological achievements of the mission, it also represents the last step of MMP development,” Silva said in a statement.
The Amazonia 1 satellite carries a wide-angle optical imager with a resolution of 210 feet (64 meters). The imaging instrument will take pictures of an area spanning up to 528 miles (850 kilometers) wide, allowing the satellite to observe a wide swath of the planet on each orbit.
The satellite’s wide viewing area will allow it to revisit the same part of the world every five days, officials said. Amazonia 1 will also monitor agriculture in Brazil and other regions around the planet, INPE said.
Amazonia 1 will work in tandem with the CBERS 4 and CBERS 4A satellites developed in partnership between China and Brazil. On those missions, China built and launched the satellites, while Brazil provided instrument hardware.
The 18 smaller payloads that rode the PSLV into orbit include 12 tiny SpaceBEE satellites from Swarm Technologies. The small data relay nodes each weigh less than 2 pounds (1 kilogram). The “BEE” in SpaceBEE stands for Basic Electronic Element.
Swarm, headquartered in Silicon Valley, is developing a low-data-rate satellite communications fleet the company says could be used by connected cars, remote environmental sensors, industrial farming operations, transportation, smart meters, and for text messaging in rural areas outside the range of terrestrial networks.
Each of the SpaceBEEs is about the size of a slice of bread. The launch of 12 new satellites came a month after SpaceX launched 36 SpaceBEEs for Swarm on a rideshare mission that lifted off from Cape Canaveral, Florida.
There was a CubeSat named NanoConnect 2 developed by Mexican students at Universidad Nacional Autónoma de México, or UNAM, in Mexico City on the PSLV mission. NanoConnect 2 will test power, computer, communications, and mechanical satellite systems in the space environment. The PSLV also carried five Indian nanosatellites from academic institutions and the Indian military. (...)
