The Indian Space Research Organisation (ISRO) carried out two successful hot tests of the Gaganyaan Service Module Propulsion System (SMPS) on July 3, 2025, at its Propulsion Complex located in Mahendragiri, Tamil Nadu. This facility is crucial for propulsion-related development and testing. These hot tests simulated real flight conditions to ensure the system's performance and reliability under operational stress. The successful validation at Mahendragiri marked a significant milestone in ISRO’s preparations for India’s first human spaceflight mission under the Gaganyaan programme. The choice of this location reflects its specialised infrastructure for high-precision propulsion experiments.
