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.

Isro moves closer to Gaganyaan launch, completes key engine development
The Indian Space Research Organisation (Isro) announced Friday 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 on Friday 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 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 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 Gaganyaan mission aims to send Indian astronauts into low-Earth orbit, approximately 400 kilometres above Earth, for several days before their safe return. This latest achievement follows other key test milestones, including the TV-D1 abort test and the first uncrewed Test Vehicle mission conducted earlier this mission will utilise the human-rated LVM3 launch vehicle, a robust Crew Escape System, and meticulously engineered Crew and Service Modules, all currently undergoing final integration and training is also progressing steadily, with three Indian Air Force pilots, now designated as astronauts, having completed initial training in Russia and continuing with mission-specific preparations in India.- EndsTune InMust Watch

Isro successfully conducts hot tests of Gaganyaan propulsion system
Isro has successfully conducted two hot tests of the Gaganyaan Service Module Propulsion System (SMPS) at the space agency's Propulsion Complex in Mahendragiri on July 3. The short-duration tests, lasting 30 seconds and 100 seconds respectively, were aimed at validating the test article configuration, Isro said in a statement on Wednesday. "The overall performance of the propulsion system during these hot tests was normal as per pre-test predictions. During the 100s test, simultaneous operation of all Reaction Control System (RCS) thrusters in different modes (steady state; pulsed) along with all Liquid Apogee Motor (LAM) engines was also successfully demonstrated. "Isro's Liquid Propulsion System Centre (LPSC) is leading the technology development activities for the Gaganyaan SMPS. SMPS is a critical system of Gaganyaan Orbital Module and is required during orbital manoeuvring as well as specific abort scenarios," the space agency said. It comprises five Liquid Apogee Motor (LAM) engines (each 440N thrust) and 16 Reaction Control System (RCS) thrusters (each 100N thrust). In order to simulate the propulsion system conditions closer to flight, the SMPS test article for these hot tests incorporated improvements based on experience gained from earlier hot tests. "With the confidence gained through these hot tests, Isro will conduct a full duration hot test shortly," the statement said. According to Isro, the Gaganyaan programme aims to demonstrate India's capability to launch a crewed spacecraft into low Earth orbit, and the experience and knowledge gained from this mission will be crucial for its success.

Gaganyaan Service Module Propulsion System completes 2 hot tests
Bengaluru: Isro Wednesday said it successfully conducted two hot tests of the Gaganyaan Service Module Propulsion System (SMPS) at its Propulsion Complex in Mahendragiri, on July 3. Tired of too many ads? go ad free now 'The short-duration tests lasted 30 and 100 seconds, respectively, and were aimed at validating the current configuration of the SMPS test article,' Isro said, adding that the propulsion system performed normally, with results aligning with pre-test predictions. Notably, the 100-second test demonstrated the simultaneous operation of all five Liquid Apogee Motor (LAM) engines and all 16 Reaction Control System (RCS) thrusters in both steady-state and pulsed modes. The Liquid Propulsion Systems Centre (LPSC), which is leading the development of the SMPS, has made design improvements based on earlier hot test campaigns to better simulate in-flight conditions. The SMPS is a key component of the Gaganyaan Orbital Module, supporting both orbital manoeuvres and certain abort scenarios. 'Each LAM engine produces 440 Newtons of thrust, while the RCS thrusters deliver 100 Newtons each. With these successful tests, Isro said it is preparing to conduct a full-duration hot test soon, a critical step as Gaganyaan moves closer to its first human spaceflight,' Isro said. Isro is hoping to carry out at least two crucial missions related to the Gaganyaan project this year. The space agency will first target the second test vehicle mission and an uncrewed mission. Based on performances of the various systems on each of these missions will determine the future course of action. Tired of too many ads? go ad free now As Isro prepares for Gaganyaan, which is being designed to send Indian astronauts to space and bring them back safely, one of the four astronaut-designates of the Gaganyaan programme, Group Captain Shubhanshu Shukla has been conducting scientific experiments aboard the International Space Station (ISS). Shukla, as part of the Axiom-4 mission, docked with the ISS on June 16 and is expected to return any day after July 9, although no formal date for the re-entry and splashdown has been announced as yet.
