ISRO moves closer to Gaganyaan launch
Bengaluru: The Indian Space Research Organisation (ISRO) has announced that it has successfully completed the development of the Service Module Propulsion System (SMPS) for its ambitious Gaganyaan human spaceflight mission, following the conclusion of its qualification test program. The milestone moves India closer to its first crewed space mission, slated for the first quarter of 2027. A full-duration hot test of the SMPS was conducted for 350 seconds at the ISRO Propulsion Complex (IPRC) in Tamil Nadu's Mahendragiri. The test was designed to validate the integrated performance of the system for a flight off-nominal mission profile, specifically an SM-based abort scenario during the ascent phase. Officials stated the propulsion system's overall performance during the test was normal and aligned with pre-test predictions. The Service Module (SM) of the Gaganyaan mission is a regulated bi-propellant propulsion system vital for various orbital manoeuvres. It is responsible for orbit circularisation, on-orbit control, de-boost manoeuvring, and crucial Service Module-based abort operations during the ascent phase. The system comprises five Liquid Apogee Motor (LAM) engines, each providing 440 Newtons of thrust for main propulsion, and 16 Reaction Control System (RCS) thrusters, each delivering 100 Newtons for precise attitude control. A dedicated System Demonstration Model (SDM) test bed, replicating the SMPS fluid circuit, was used for the extensive qualification programme. This SDM underwent 25 tests under both nominal and off-nominal conditions, accumulating a total duration of 14,331 seconds, to meet various Gaganyaan mission scenarios and human-rating requirements. The Gaganyaan Service Module Propulsion System was designed, developed, and developed by ISRO's Liquid Propulsion Systems Centre (LPSC). Its robust design and successful testing are considered essential for ensuring crew safety and the overall success of the mission, particularly its capability to handle complex manoeuvres and emergency abort scenarios. Gaganyaan mission aims to send Indian astronauts into low-Earth orbit, approximately 400 kilometres above Earth, for several days before their safe return.

Isro completes key propulsion system development for Gaganyaan
BENGALURU: Isro has successfully completed the development of the Service Module Propulsion System (SMPS) for the Gaganyaan human spaceflight mission, marking a milestone in the programme's progress. The qualification test programme concluded with a full-duration hot test of the SMPS that lasted 350 seconds. 'The test, conducted on July 11, validated the propulsion system's integrated performance for an off-nominal mission profile involving a service module-based mission abort. The system performed normally, as predicted,' Isro said. The service module of Gaganyaan is a regulated bi-propellant propulsion system. It enables orbit circularisation, on-orbit control, de-boost manoeuvres, and provides abort capability during ascent. 'The main propulsive force comes from the Liquid Apogee Motor (LAM) engines, while Reaction Control System (RCS) thrusters ensure accurate attitude control,' Isro said. To support testing, Isro developed a System Demonstration Model (SDM) replicating the fluid circuit of the SMPS, including propellant feed, helium pressurisation, flight-qualified thrusters, and control components. This testbed underwent 25 tests under both normal and off-nominal conditions, totalling 14,331 seconds, to meet various mission and human-rating requirements. The SMPS was developed by the Liquid Propulsion Systems Centre (LPSC), and all tests were carried out at the Isro Propulsion Complex in Mahendragiri.

India's crewed space mission: Gaganyaan Propulsion System clears tests — Why this matters
. With India's first astronaut on the International Space Station, Shubhanshu Shukla, currently in space, the country has achieved another important milestone in its crewed space journey. Isro on Saturday said it has successfully completed the qualification tests for the Gaganyaan Service Module Propulsion System (SMPS). A 350-second hot test was conducted on Friday at the Isro Propulsion Complex in Tamil Nadu, validating the system's performance during off-nominal mission scenarios such as flight aborts. With this, Isro moves closer to launching astronauts into space which will include Shubhanshu Shukla, currently on ISS. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like [속보]'한 달만에 5cm 성장!?' 2개월치 무료증정 압도적 키성장 1위! 아이클타임 더 알아보기 Undo What is the propulsion system in Gaganyaan? The propulsion system is like the engine of the Gaganyaan Service Module. It helps move and control the spacecraft once it is in space. This includes tasks like adjusting the orbit, changing direction, slowing down before returning to Earth, and helping with emergency escape if something goes wrong during launch. The system runs on a special mix of two types of fuel (called bi-propellant) and has two key parts — the Liquid Apogee Motors (LAM), which handle big movements, and the Reaction Control System (RCS) thrusters, which help turn or adjust the position of the spacecraft. To test all this, Isro built a model that copies how the real system would work in space. This model had fuel tanks, helium gas for pressure, and all the necessary pipes and controls. Isro tested this model 25 times under different conditions — both normal and emergency-like situations. In total, the engine was fired for over 14,000 seconds to make sure it is safe and ready for astronauts. Why is this important? This test is a big step forward for India's Gaganyaan mission , which aims to send astronauts into space. The 350-second trial was done to check if the engine works properly even during emergency situations — like if the mission has to be stopped in the middle of launch. Isro said the system worked just as expected. The engine system, called SMPS, was developed by ISRO's Liquid Propulsion Systems Centre (LPSC) and tested at their Propulsion Complex in Mahendragiri, Tamil Nadu. This success means Isro has crossed an important stage in making sure the spacecraft is safe for humans. Now, the team will focus on more testing and putting all parts together before the actual astronaut mission is launched. Once Gaganyaan takes off, India will become the fourth country in the world after the US, Russia, and China, to send people into space using its own technology

Isro completes developing Service Module Propulsion System for Gaganyaan
Isro on Saturday said it has successfully completed the development of Service Module Propulsion System (SMPS) for Gaganyaan Mission with the completion of the qualification test programme. A full duration hot test of SMPS for 350 seconds was conducted to validate the integrated performance of the SMPS for flight off-nominal mission profile of the Service Module based mission abort on Friday. Gaganyaan mission is India's first human spaceflight mission in the making. "The overall performance of the propulsion system during the hot test was normal as per pre-test predictions," Isro said in a statement. According to the space agency, "The Service Module (SM) of Gaganyaan is a regulated bi-propellant based propulsion system that caters to the requirements of the Orbital Module for orbit circularisation, on-orbit control, de-boost manoeuvring and Service Module based abort during the ascent phase." The Liquid Apogee Motor (LAM) engines provide the main propulsive force during the orbit circularisation and de-boost phases, while the Reaction Control System (RCS) thrusters ensures precise attitude control, it added. "A System Demonstration Model (SDM) test bed was realised emulating the fluid circuit of the SMPS, encompassing the propellant tank feed system, helium pressurisation system, flight-qualified thrusters, and control components," Isro said. It added that the SDM for SMPS has undergone 25 tests under nominal and off-nominal conditions for a cumulative duration of 14,331s for various Gaganyaan mission scenarios and human rating requirements. The space agency said the Gaganyaan Service Module Propulsion System is designed, developed, and realised by Liquid Propulsion Systems Centre (LPSC) and the tests were carried out at Isro Propulsion Complex (IPRC), Mahendragiri in Tamil Nadu.
