ISRO successfully conducts hot tests of Gaganyaan propulsion system
Bengaluru (PTI): 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.

If you have a conscience, apologize to the people: R Ashoka slams Yathindra over Nalwadi comparison
Bengaluru: Leader of the Opposition R. Ashoka launched a scathing attack on MLC Dr. Yathindra, demanding that he retract his controversial statement comparing Chief Minister Siddaramaiah to the late Maharaja Nalwadi Krishnaraja Wadiyar. Ashoka urged Yathindra to apologize to the people of Karnataka if he had even a shred of conscience and any respect for the Mysuru royal lineage.
In a strongly worded social media post on Sunday, Ashoka stated, “Comparing Siddaramaiah to Nalwadi Krishnaraja Wadiyar is nothing short of absurd. Where is Nalwadi, who was bestowed the title of ‘Rajarshi’ by Mahatma Gandhi himself, and where is Siddaramaiah, who has stooped to being a puppet in the hands of fake Gandhis for the sake of power?”
He continued his critique by contrasting the enduring legacy of Nalwadi, remembered fondly by Kannadigas for his people-centric development, with what he termed as Siddaramaiah’s failure to manage Karnataka’s economy, burdening every household with debt.
Ashoka highlighted several stark differences, while Nalwadi built Mysore University over a century ago, Siddaramaiah is shutting down nine universities due to lack of funds. Nalwadi famously sold his family’s gold to build the KRS dam, whereas Siddaramaiah is accused of grabbing 14 sites meant for the public. Nalwadi established Bhadravati Iron & Steel Plant, Sandalwood Soap Factory, and Mysore Paper Mills. In contrast, Ashoka claimed Siddaramaiah's governance drove away industries, investors, and entrepreneurs. Nalwadi pioneered reservations for the backward classes long before it became mainstream. Siddaramaiah, Ashoka alleged, is reducing social justice to a gimmick by sticking labels on doors in the name of surveys.
While acknowledging Yathindra’s emotional attachment to his father, Ashoka emphasized that comparing Siddaramaiah to a visionary like Nalwadi was “laughable, baseless, and a gross insult” to the late king.
In his concluding remarks, Ashoka slammed the government for ignoring farmers’ needs despite an early monsoon. He accused the administration of being caught up in internal power struggles and negligence, forcing farmers into despair. “This government will not be spared from the curse of the farmers,” he warned.
