Private aerospace firms from India and Brazil have entered into a landmark two-year agreement to evaluate the joint development of a small-satellite launch vehicle.

The partnership brings together Hyderabad-based Skyroot Aerospace and Brazilian firm Concert Technologies, which operates as a member of Brazil’s Micro Launcher Program consortium.

Under the terms of the newly signed memorandum of understanding, the two enterprises will study the feasibility of a rocket engineered to deliver payloads of at least 100 kilograms into low Earth orbit.

This exploratory pact was formally inked in October by Concert Space chief executive Rafael Mordente on the sidelines of the International Astronautical Congress held in Antalya, Turkey.

High-level dignitaries attended the signing ceremony, including Brazilian Senator and former astronaut Marcos Pontes alongside Marco Antonio Chamon, the President of the Brazilian Space Agency.

The collaboration marks a significant expansion of bilateral space cooperation between the two emerging spacefaring nations, shifting focus directly into commercial launch-vehicle engineering.

By targeting a minimum payload capacity of 100 kilograms, the proposed launcher is strategically positioned to fill a critical gap in the global commercial spaceflight market.

Currently, Brazil’s planned Micro-launcher Program vehicle is designed to carry payloads of up to 40 kilograms, leaving a capability void for slightly heavier spacecraft.

Conversely, Skyroot Aerospace is developing its larger Vikram rocket family, which caters to more substantial orbital missions.

A jointly developed 100-kilogram-class rocket would give both companies a competitive middle-tier option tailored for satellite operators whose payloads exceed micro-launcher limits without warranting the cost of a larger launch vehicle.

Beyond evaluating launch vehicle specifications, the two-year agreement outlines a broader scope for potential technical and commercial synergy.

Both firms plan to assess market demand, establish technical requirements, and investigate joint opportunities in satellite systems and low Earth orbit constellations.

The partnership also opens the door to exploring equatorial launch operations, leveraging geographical advantages that reduce the fuel required to reach specific orbits, though no specific launch site has been confirmed.

Crucially, the memorandum of understanding represents an initial exploratory phase rather than a binding commitment to construct or fly a rocket.

Neither company has committed to launching from Brazilian territory, and key operational details remain undecided at this stage. The current agreement does not specify the rocket's final architectural design, development budget, work-share division, target launch date, or designated spaceport.

Subsequent binding contracts will be necessary to govern capital investments, hardware and equipment supply chains, and final commercialisation strategies.

For Brazil’s burgeoning private space sector, partnering with Skyroot provides direct access to proven launch-vehicle engineering and flight heritage.

Concert Technologies brings valuable domestic expertise to the table through its consortium work in propulsion systems, guidance, navigation, and control technologies.

Integrating Brazilian subsystem capabilities with Skyroot’s established rocket development program could accelerate technological maturity for both partners.

Simultaneously, the alliance grants Skyroot Aerospace an experienced local partner with deep institutional knowledge of Brazil’s aerospace industry and regulatory launch ecosystem.

Founded in 2018, Skyroot Aerospace has rapidly emerged as a leading Indian space start-up, making history in 2022 as the first private company in India to successfully launch a rocket into space with its sub-orbital Vikram-S mission.

While the pact substantially broadens Skyroot’s international footprint, the official announcement has not yet detailed the exact components or proprietary technologies each firm will contribute to the prospective vehicle.

As global demand for dedicated small-satellite deployments continues to surge, this Indo-Brazilian feasibility study lays the groundwork for a potentially vital new corridor in commercial orbital access.
