ISRO conducts successful tests for Gaganyaan mission
BENGALURU: As Group Captain Shubhanshu Shukla, India's first astronaut and Gaganyatri, is gaining first hand knowledge of manned space missions onboard the International Space Station as part of the Axiom-4 mission, the Indian Space Research Organisation (ISRO) team is also working over time to be on schedule for the launch of the Gaganyaan mission -- the first indigenous manned space mission. ISRO on Wednesday shared details of the successful completion of two hot tests of the Gaganyaan Service Module Propulsion System. The tests were conducted for a 30 seconds and 100 seconds to validate the test article configuration. The ISRO team stated that all parameters and performance of the propulsion system during these hot tests were as per the pre-test indicators and normal. ISRO Chairman V Narayanan said the team has planned to launch the Gaganyaan mission in March 2027. 'For success in the first attempt, a series of tests and preparations are important and they are being done step by step.' RCS thrusters with LAM working fine: ISRO 'Each test parameter is also being doubly checked to ensure there are no anomalies at later stages,' Narayanan said. The ISRO team on Wednesday said the tests of reaction control system (RCS) thrusters in all the different modes along with the Liquid Apogee Motor (LAM) were found to be successful. 'The ISRO's Liquid Propulsion System Centre (LPSC) is leading the technology development activities for the Gaganyaan's Service Module Propulsion System (SMPS). SMPS is a critical system of Gaganyaan Orbital Module. It is required during orbital manoeuvring and for specific abort scenarios. It comprises five 5 LAM engines and 16 RCS thrusters. Now with the results and input gained from these short hot tests, ISRO will soon conduct a full duration hot test,' the ISRO team said.

ISRO successfully conducts hot tests of Gaganyaan Service Module Propulsion System
States » South Chennai, July 9 (UNI) ISRO has successfully conducted two hot tests of the Gaganyaan Service Module Propulsion System (SMPS) at ISRO Propulsion Complex (IPRC), Mahendragiri in Tamil Nadu. The tests were conducted on July 3, ISRO said in an update today. The two short duration hot tests were conducted for 30s and 100s to validate the test article configuration. 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 RCS thrusters in different modes (steady state; pulsed) along with all 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. It comprised of five Liquid Apogee Motor (LAM) engines (each 440N thrust) and 16 of 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. UNI GV 1640

ISRO conducts 2 hot tests of Gaganyaan Service Module Propulsion System
New Delhi: ISRO on Wednesday said it has successfully conducted two hot tests of the Gaganyaan Service Module Propulsion System (SMPS), a key advancement for the Gaganyaan human spaceflight mission. The hot tests were carried out on July 3 at the ISRO Propulsion Complex (IPRC) in Mahendragiri in Tamil Nadu's Tirunelveli District. 'Two short-duration hot tests were conducted for the 30s and 100s to validate the test article configuration. The overall performance of the propulsion system during these hot tests was normal as per pre-test predictions,' ISRO said. "During the 100s test, simultaneous operation of all RCS thrusters in different modes (steady state; pulsed) along with all LAM engines was also successfully demonstrated," the agency added. ISRO's Liquid Propulsion System Centre (LPSC) is leading the technology development activities for the Gaganyaan SMPS. SMPS is a critical system of the Gaganyaan Orbital Module and is required during orbital manoeuvring as well as specific abort scenarios. It comprises of 5 Nos. of Liquid Apogee Motor (LAM) engines (each 440N thrust) and 16 nos. of 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 Indian space agency said. Gaganyaan is India's human spaceflight mission slated for launch in 2027. The Gaganyaan programme aims to demonstrate India's capability to launch a crewed spacecraft into low Earth orbit. ISRO aims to launch at least two key projects under the Gaganyaan mission this year -- a second test vehicle and an uncrewed mission. The uncrewed orbital test mission will pave the way for India's human spaceflight programme. This will validate systems for crew safety and recovery. Meanwhile, Group Captain Shubhanshu Shukla, part of one of the four astronaut-designates of the Gaganyaan programme, has also been conducting scientific experiments aboard the International Space Station (ISS) that may help the human space flight mission for the country.
