Manastu Space

Manastu Space Technologies is an India-based space startup founded in 2017 (with roots in IIT Bombay's Student Satellite Lab) that develops non-toxic green propulsion systems and debris collision-avoidance technology for satellites and launch vehicles. Its systems use a proprietary hydrogen-peroxide-based green propellant (MS-289) to replace traditional toxic hydrazine. In December 2024 it test-fired its Vyom 2U thruster in orbit aboard ISRO's PSLV Orbital Experimental Module-4 (POEM-4) and delivered India's first green propulsion system to DRDO.
