Manastu Space

Manastu Space is an Indian aerospace technology company developing green propulsion systems for satellites, orbital transfer vehicles, and launch vehicle upper stages. Its propulsion technology uses hydrogen peroxide-based propellants, including the proprietary MS289 formulation, as alternatives to conventional toxic spacecraft fuels. The company’s product portfolio includes Vyom 2U, I-Booster, Sharanga, and GP-LAM propulsion systems for spacecraft of different sizes and mission requirements. Manastu Space has also conducted in-orbit propulsion testing through its Adyanta mission, demonstrating technology for satellite maneuvering, station-keeping, collision avoidance, and spacecraft deorbiting.
Tesseract

Tesseract Space is a space technology company developing chemical propulsion systems for satellites and spacecraft operating in Earth orbit and beyond. The company designs and manufactures low-toxicity thrusters, multi-thruster modules, and integrated propulsion systems that support spacecraft maneuvering, orbital adjustments, and mission operations. Its propulsion technology offers an alternative to traditional highly toxic propellants, while its modular hardware architecture allows spacecraft manufacturers to select individual components or complete propulsion solutions based on mission requirements.
