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.

National Herald case: Shivakumar to seek time next week to appear before Delhi police
New Delhi/Bengaluru (PTI): Karnataka Deputy Chief Minister D K Shivakumar on Monday said he will ask for time from Delhi police to appear before them next week, to provide required information as part of the probe into the National Herald case.
He said he will seek time after the ongoing winter session of Karnataka legislature ends on December 19. He will also ask the Delhi police to provide him the FIR copy.
Shivakumar, who is in the national capital, had earlier said that he will appear before the Delhi police on Monday. But, he postponed the plan in order to rush back to Karnataka to participate in the last rites of veteran Congress leader Shamanuru Shivashankarappa, scheduled later in the day in Davangere.
"I had to go (to appear before the Delhi police), but I have to go back urgently. I'm asking them for time, stating that I will come next week," Shivakumar told reporters in New Delhi.
"They (Delhi police) have not attached the FIR copy while issuing notice to me. I need FIR copy, because we had already given all the required replies to the ED. I don't know what the FIR says, I only read in papers. They have given notice, I will ask for a FIR copy. I will come next week after the Assembly session."
The Delhi Police had issued a notice to Shivakumar, who is also the Karnataka Congress chief, seeking financial and transactional details as part of its probe into the National Herald case.
The notice issued by the Economic Offences Wing (EOW) states that Shivakumar is "supposed to be having vital information" pertaining to the National Herald case registered on October 3 this year, against top Congress leaders Sonia Gandhi and Rahul Gandhi.
In the notice dated November 29, the EOW had asked Shivakumar to appear before it or provide the requested information by December 19 latest.
Investigators have sought details about his personal background, his association with the Congress party, and a complete break up of funds allegedly transferred by him or associated entities to Young Indian.
To a question on meeting AICC General Secretaries K C Venugopal and Randeep Singh Surjewala, amid the ongoing power tussle between him and CM Siddaramaiah over the Chief Minister post, Shivakumar said when he comes to Delhi, he usually meets every one.
"Whether it is Surjewala or Kharge (AICC President Mallikarjun Kharge) or Venugopal, I will meet everyone. During lunch yesterday I met Rahul Gandhi and Sonia Gandhi. I have met everyone. What's wrong?" he asked.
Shivakumar was in Delhi to take part in Congress' "Vote Chori" rally on Sunday, and had also participated in the lunch organised by the party for its leaders.
Responding to a question, whether any meeting is planned with leaders today, the Deputy CM said, he and Kharge will be travelling together to Karnataka, to pay last respects to Shamanuru Shivashankarappa.
Asked if he will seek time for a separate meeting with Congress leadership including Rahul Gandhi, during the next visit to Delhi, Sivakumar said, "such things will be there between us in the party.... you don't worry."
