Brazil wins crucial phase and is close to launching 1st orbital rocket

The MLBR (Brazilian Microlauncher) has advanced in one of the stages considered most important in the national rocket project that is being developed to launch satellites into Earth's orbit.

According to those responsible for the program, preparations have been completed for the first shipments of the engines that will equip the space vehicle. Among the main advances are the formulation of the inert propellant used in the initial tests and the completion of the envelopes for the N-04 and N-09 propellants, which will equip the second and third stages of the rocket.

The use of inert propellant is considered strategic because it allows operational procedures, quality requirements and safety protocols to be validated before the use of active propellant in the next phases of the project.

The teams are also now advancing in the manufacturing and testing of equipment necessary for engine loading operations, including the central mandrel responsible for the internal geometry of the propellant grain.

The three MLBR engines have already had their structures qualified. The N-90 model, which will be used in the first stage of the rocket, uses around nine tons of propellant. The N-09 uses approximately one ton, while the N-04 uses around 400 kilos.

According to those responsible for the project, the inert loads represent another important step towards the technological maturation of the Brazilian space program.

"The advancement of preparations reinforces the continuous evolution of MLBR towards the objective of contributing to the expansion of Brazil's capacity for independent access to space", stated Ralph Correa, program manager and engineer at Cenic Engenharia.

The MLBR aims to be the first vehicle in the country capable of placing small satellites into Earth orbit from the national territory.

Engine test
At the end of May, the space startup BIZU Space successfully carried out the test of the first flight model of the ARION liquid rocket engine, considered an important advance for Brazilian space propulsion.

The test was part of the mission "Deitado em Berço Esplendido" (DeBE), a campaign aimed at horizontal validation of the ablative version of the engine. The engine was developed and manufactured entirely by the company itself and uses hydrogen peroxide as an oxidizer and aviation kerosene as fuel.

The test took place on the T8 test bench, the company's own infrastructure located on the campus of the University of Vale do Paraíba, in São José dos Campos (SP).

The campaign aimed to validate technologies considered critical to the Brazilian space program, including tank systems, valves, control and integration of the propulsion set.

The project is sponsored by FINEP (Financier of Studies and Projects), linked to MCTI (Ministry of Science, Technology and Innovation), in partnership with AEB (Brazilian Space Agency). At a cost of R$189 million, the MLBR rocket should be launched into space in 2026. Other companies are part of the rocket's design: Concert, Etsys, Delsis and Plasmahub.

Brazilian attempt
The project could achieve a previously distant goal in 2026: for the first time, launching an orbital rocket from a national launch center. Furthermore, with Brazilian equipment.

"The vehicle will have twelve tons on the [launch] ramp to carry a payload weighing just 40 kilos into orbit. With these small satellites you can do a lot of things nowadays. This is a billion-dollar market.

Brazil is privileged in terms of launch, with a magnificent geographic base", says Ralph Corrêa, director of Cenic Engenharia, in an interview with CNN Brasil.
