The test conducted for 450 seconds met the test objectives and matched the pre-test predictions. ISRO further plans a series of hot tests to simulate various mission conditions as well as off-nominal conditions. ISRO tweeted to share the achievement of a successful hot test of the System Demonstration Model (SDM) of the Gaganyaan Service Module Propulsion System.
