ISRO successfully conducts first hot test of Gaganyaan Service Module Propulsion System

The Indian Space Research Organisation recently conducted a hot test on its Gaganyaan Service Module (SM) Propulsion System on 28 August.

This was the first hot test of the System Demonstration Model (SDM) of the Gaganyaan SM Propulsion System which differs from the hot test the agency conducted on the Vikas engine.

Gaganyaan Mission: The Indian Space Research Organization (ISRO) on August 28, 2021, successfully conducted the first hot test of the System Demonstration Model (SDM) of the Gaganyaan Service Module Propulsion System at the test facility of the ISRO Propulsion Complex (IPRC) in Mahendragiri, Tamil Nadu. 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.

The Gaganyaan Service Module Propulsion System is a part of the Gaganyaan Orbital module of the Gaganyaan Mission, India’s first human spaceflight mission. ISRO on July 14, 2021, successfully conducted the third long-duration hot test of the liquid propellant Vikas Engine for the GSLV MkIII launch vehicle for the Gaganyaan Mission.
