ISRO successfully tested Gaganyaan propulsion system, testing lasted for 30 and 100 seconds; know its importance
ISRO conducted two successful tests of the Gaganyaan Service Module Propulsion System (SMPS) which lasted for 30 and 100 seconds. Their aim was to validate the configuration of the test article. The performance of the propulsion system was normal. In the 100-second test, the performance of all the reaction control system thrusters and liquid apogee motor engines was successful.
ISRO carried out two successful trial runs of the Gaganyaan Service Module Propulsion System (SMPS) at its propulsion complex in Mahendragiri on July 3. The tests were conducted for a short duration of 30 seconds and 100 seconds, respectively.
ISRO said on Wednesday that their aim was to validate the configuration of the test article. The overall performance of the propulsion system throughout the test was as predicted before the test. Concurrent operation of all the Reaction Control System (RCS) thrusters in different modes and all the Liquid Apogee Motor (LAM) engines during the 100-second test was successfully demonstrated.
ISRO's Liquid Propulsion Systems Centre (LPSC) is spearheading a technology development program for Gaganyaan SMPS, according to the space agency. SMPS is one of the vital systems of the orbital module of Gaganyaan and is needed during orbital maneuvering as well as certain abort conditions.
It consists of five Liquid Apogee Motor engines (440 Newton thrust each) and 16 Reaction Control System thrusters (100 Newton thrust each). To simulate conditions closer to flight of the propulsion system, improvements were incorporated in the SMPS test article for these tests based on the experience gained in the past.

With the confidence gained through these, ISRO will soon conduct a full-duration test. According to ISRO, the objective of the Gaganyaan programme is to demonstrate India's capability to launch a manned spacecraft into low Earth orbit, and the experience and knowledge gained from this mission will be crucial to its success.
