Mumbai-based Manastu Space is innovating green thrusters to replace traditional propellants for satellites and launch vehicles. Founded by IIT Bombay alumni, the startup utilizes a proprietary fuel, MS289, that is safer and more efficient than hydrazine.

Key products include the Vyom 2U and iBooster systems. A successful test-fire of the Vyom 2U on ISRO's PSLV-C60 mission validated its performance. Manastu aims to enhance fuel efficiency and reduce costs while supporting India's self-reliance in space technology.
