The agreement enables collaboration with ISRO experts under a Joint Project Implementation Plan for design validation and testing rocket engines.
Astrophel Aerospace has signed a framework Memorandum of Understanding with the Indian National Space Promotion and Authorisation Centre (IN-SPACe) to advance semi-cryogenic propulsion technology for reusable launch vehicles. The arrangement grants the Pune-based company access to Indian Space Research Organisation (ISRO) infrastructure for system-level testing, component qualification, and technical reviews.
The MoU includes a Joint Project Implementation Plan, under which ISRO specialists will support design validation and testing programmes for propulsion subsystems such as turbopumps and engine modules.
The agreement comes after Astrophel secured ₹68.4 million in funding to develop its Astra-series reusable launch hopper. The company is targeting an additional USD 5 million in funding to accelerate engine development and increase production of cryogenic components. Astrophel’s work spans valves, turbopumps, and avionics, with potential applications across clean energy, industrial gas systems, defence, and broader energy markets.
The startup reported a milestone in August 2023 when it test-fired an open-cycle semi-cryogenic engine without external investment, at a cost of ₹600 thousand. The modular design is aimed at cost efficiency and scalability, supported by a team with prior experience at ISRO, DRDO, and HAL.
Astrophel plans its first suborbital launch as part of the current development cycle and aims to deliver a fully reusable hopper prototype within the next 24 to 36 months.
IN-SPACe, under the Department of Space, facilitates private-sector participation in space missions and technology development. The partnership is positioned to help Astrophel progress towards commercial readiness in the reusable spaceflight segment, a growing focus area for global launch providers seeking to reduce mission costs and improve turnaround times.
