Manastu Space

We are an Indian space-tech company specialising in green propulsion systems. Founded by IIT Bombay alumni, the company provides full-stack manoeuvrability solutions for modern satellite missions and kick-stages of launch vehicles. The rapid increase in satellite launches is significantly raising the risk of in-orbit collisions, making reliable propulsion essential for maneuvering and end-of-life de-orbiting. However, existing systems rely on toxic fuels like hydrazine, which are expensive to handle, require complex ground infrastructure and create operational challenges. Manastu addresses this with a hydrogen-peroxide based green propulsion system that is safer, cost-efficient and designed for rapid integration, enabling agile maneuvering, collision avoidance and sustainable satellite operations at scale. Manastu Space combines flight heritage, early international contracts, and a globally relevant, scalable propulsion solution, positioning it strongly for export readiness and rapid expansion across key space markets. From space-qualified hardware on ISRO missions to strategic defense collaborations, Manastu Space is committed to safe satellite missions while reducing the environmental footprint of space exploration. With a team of 100+ experts and a legacy of innovation in high temperature catalyst, green propellant and advanced combustion chamber, spanning 9 years, we are propelling the next generation of sustainable space missions.
