The Indian Space Research Organisation on Monday achieved a significant milestone with the successful completion of the third hot test of the Power Head Test Article (PHTA) at the Isro Propulsion Complex in Mahendragiri, Tamil Nadu.
The test is part of a crucial series of evaluations to validate the performance of India's upcoming semicryogenic engine, Isro said.
This marks the third in a series of hot tests undertaken by Isro for the PHTA.
According to Isro, the test, conducted on May 28, was aimed at validating the engine's ignition and start-up sequence while optimising the process for integrated engine performance.
During the three-second trial, the engine was ignited successfully and operated up to 60 per cent of its rated power level, exhibiting stable and controlled performance throughout.
Isro began this series of performance evaluations in March 2025, focusing on critical components such as low- and high-pressure turbo-pumps, the pre-burner, start-up system, and various control mechanisms.
The first test, conducted on March 28, 2025, confirmed smooth ignition and bootstrap operation during a 2.5-second run.
The second test, carried out on April 24, focused on the start transient build-up and validated the ignition sequence over a 3.5-second duration.
The Semi-Cryogenic Propulsion Stage (SC120), powered by the 2000 kN-class SE2000 engine, is being developed to replace the current liquid core stage (L110) of the LVM3 launch vehicle towards enhancing its payload capability, Isro said.

Axiom-4 mission: Group Captain Shubhanshu Shukla commences research activities aboard ISS
Group Captain Shubhanshu Shukla, who is aboard the International Space Station (ISS) has commenced research activities at the orbiting laboratory According to Axiom Space the crew members are fully immersed in their mission aboard the ISS having transitioned smoothly from arrival protocols to hands-on research. Axiom Space said that Shux (Group Captain Shukla mission call sign) spent time in the Life Sciences Glovebox (LSG) working on the Myogenesis experiment. 'This study aims to uncover the biological pathways behind skeletal muscle degradation in space—a major challenge for astronauts. By identifying these mechanisms, researchers hope to develop targeted therapies that could not only protect space travelers but also aid people suffering from muscle-degenerative diseases on Earth,' Axion Space said. ISRO has shortlisted seven microgravity research experiments proposed by Indian (PIs) from various national R&D laboratories and academic institutions which Group Captain Shukla would be conducting during his 14-day stay at the ISS. Myogenesis is one of the them which has been proposed by the Bengaluru based Institute of Stem Cell Science and Regenerative Medicine (InStem). ISRO has said the experience gained through this effort in implementation of the seven experiments is expected to nurture a microgravity research ecosystem in India resulting in the induction of advanced microgravity experiments in various disciplines in the Indian space programme. In addition to the seven experiments ISRO and NASA will also be participating in five joint science investigations and two in-orbit STEM (science, technology, engineering, and mathematics) demonstrations. Axiom said that the crew initiated the Cerebral Hemodynamics study, completing the first session after installing the necessary software. 'Using ultrasound technology, this research explores how blood circulates in the brain under microgravity conditions. The findings could improve our understanding of cardiovascular adaptation in space and inform medical diagnostics and treatments for conditions like stroke and hypertension on Earth,' it said. The Axiom-4 mission research complement includes around 60 scientific studies and activities representing 31 countries, including the U.S., India, Poland, Hungary, Saudi Arabia, Brazil, Nigeria, UAE, and nations across Europe.

American woman applauds India's space programme after Shubhanshu Shukla enters ISS: ‘Top space power'
In a heartfelt and widely-shared Instagram video, an American woman has praised India's growing stature in space exploration, shortly after Group Captain Shubhanshu Shukla made history by becoming the first Indian to enter the International Space Station (ISS). An American woman's video praising India's space feats went viral.(Instagram/kristenfischer3) Kristen Fischer, the woman behind the viral video, took to Instagram to celebrate India's recent space milestone, saying, "India just successfully launched their astronaut into the International Space Station. While this is an accomplishment on itself, did you know these other facts about the Indian Space Program?" (Also read: American woman leaves 'average' life in US for extraordinary journey in India, calls it life-changing) A powerful tribute to ISRO Fischer went on to highlight several key achievements of the Indian Space Research Organisation (ISRO), noting that it was founded in 1969 and is one of only six space agencies globally. She added, "India's Mars mission, Mangalyaan, was the first interplanetary mission and cost only $74 million. To put that into perspective, NASA spent over a billion dollars on their first Mars mission." Emphasising India's reputation for low-cost innovation, she continued, "India was the first nation to reach Mars on the first try and the third nation to reach Mars overall. Also, India's Chandrayaan-1 mission in 2008 was the first to detect water molecules on the moon, which was then later confirmed by NASA." Fischer also pointed out that ISRO holds several world records, including launching the lightest satellite and the most satellites in a single mission. Caption applauds India's progress Her video, viewed over 36,000 times, was shared with a caption that read, "Did you know that India's space program was so impressive!? First founded in 1969, the ISRO is one of only 6 national space programs worldwide… India is definitely on track to be a top space power in the world." She added, "When people talk about India, they often talk about underdeveloped parts. They don't often talk about the parts where India is excelling in technology and worldwide advancement. I think it is worth acknowledging the successes India has had in their amazing space organisation!" Watch the clip here: Viewers applaud her passion The video struck a chord with Indian and international audiences alike. One viewer remarked, 'You look more excited than Indians. You love India more than Indians!' Another added, 'Yes, it's a proud moment for us. Jai Hind.' Others praised her research and sentiment, saying, 'Well researched information! India has the potential to give its best!!' and 'Kudos to you, Kristen, for recognising the advancements in our space program.' A particularly thoughtful comment read, 'Wow, you know more than so many people about ISRO. Thank you for sharing this information and congratulations to the Indian space programme.' Historic mission to the ISS Kristen's video came on the heels of India's proud moment in space exploration. On 26 June, the Axiom-4 mission's Dragon spacecraft successfully docked with the ISS after a 28-hour journey. Group Captain Shubhanshu Shukla, serving as mission pilot, joined veteran astronaut Peggy Whitson and two other crew members on this milestone mission.
