Every propulsion program reaches a stage where testing stops being about “Can it fire?” and starts becoming about “Does it behave exactly as predicted?” The Final Integrated Qualification Firing of our BSE-II engine was one of those moments. This terminal hot fire campaign delivered performance exactly aligned with our analytical predictions, simulation models, and expected operating behaviour developed throughout the program. But BSE-II was never just about a single engine. It was about building the capability to design, test, iterate, and validate Reusable Propulsion Systems completely in-house as a team. Over the course of this campaign, we strengthened not only the engine itself, but also the engineering processes, end-to-end infrastructure, control systems, testing workflows, and propulsion validation capabilities required for reusable launch systems. With the successful completion of the BSE-II campaign, our focus now advances toward the next phase of the AbyoKalaM Cryogenic series and our Reusable Rocket prototype development program, alongside dual-use technologies for civil and defence applications. #Abyom #RocketEngineering #Defence #Engine #ReusableRockets ISRO - Indian Space Research Organization DRDO, Ministry of Defence, Govt. of India India-DST Anusandhan National Research Foundation (ANRF) Birla Institute of Technology and Science, Pilani BITS Pilani, Hyderabad Campus IN-SPACe Jainul Indian Institute of Technology, Madras IITM Incubation Cell IITM Pravartak Technologies Foundation GUSEC BITS Pilani Hyderabad Campus TBI Society (TBIS) Vikas Monica Anuj Technology Development Board PIEDS : Pilani Innovation & Entrepreneurship Development Society, BITS Pilani YourStory Media Startup Pedia Startupro.in IADN Centre Prof. V Ramgopal Sanjiv Tamaswati Sachin Arun CA ANAND CA Murtaza Office of the Principal Scientific Adviser to the Government of India

As we progress towards our Flight Ready Engine (FRE) & HOPE Vehicle development program, we have successfully executed the BSE-II engine hot fire test campaign. This phase focused on validating key reusability technologies - including injection, throttling, and ignition operating at ~12 bar chamber pressure and temperatures exceeding 2200°C. Building on our BSE-I campaign, where we demonstrated India’s first Pintle Injection mechanism, BSE-II takes us a step further with stable combustion under blow-down feed conditions, refined impingement mixing architecture, and expected plume behavior, including Mach diamond formation during firing. The entire testing stack - engine, test bench, control systems, test instrumentation and the DAQ system — has been fully designed and developed in-house by Team Abyom SpaceTech & Defence. This campaign successfully validated combustion stability, chamber pressure targets, and overall integrated system performance. Each step like this strengthens not just our propulsion systems, but also the ecosystem required to build reliable, reusable launch capabilities - contributing to India’s growing strength in Space and Defence. Small engine. Big step forward.

On National Youth Day, Dainik Bhaskar Group (दैनिक भास्कर) featured us on the front page alongside some of India’s most inspiring young achievers. Congratulations to every young mind shaping India’s growth journey across sports, science, startups, social impact, and beyond. This moment reflects the power of dreams backed by discipline and the courage to challenge the impossible. It represents the true spirit of India’s youth—those who dare to dream big, question limits, and work relentlessly to build a better future. From small towns to the national spotlight, moments like these reaffirm our belief that innovation has no pin code, and determination can truly turn ambition into reality. At Abyom SpaceTech & Defence, we take this as a reminder of our responsibility to keep building, innovating, and contributing to the nation through space & defence technology. #NationalYouthDay #YouthOfIndia #AbyomSpaceTech #DainikBhaskar #YoungIndia #SpaceTech #Defence #DreamBig

Last month, we successfully conducted dual M-Class solid rocket motor tests, achieving a peak chamber pressure of 21 bar and a combined total impulse of ~8,400 Ns across both firings. Test-1 achieved a Peak thrust of 2,900 N, and Test-2: a peak thrust of 3,000 N. These results mark a strong validation of our in-house design, manufacturing, and test infrastructure, reinforcing our readiness for higher-performance propulsion systems. Congratulations to Indian Institute of Technology, Bombay IITB Rocket Team for competing in the 10k SRAD category at IREC 2026. We’re proud to support industry and academia pushing the boundaries of indigenous aerospace innovation. Our Rocket Engine Test Facility is now fully operational and open to external partners, enabling academia, startups, and industry to accelerate development through reliable, commercial-grade testing. As we move into 2026, we’re gearing up for multiple milestones focused on #Reusability, scale-up, and commercialization of critical Space & Defence technologies—building the backbone for India’s next generation of launch systems. #Abyom #AbyomSpaceTech #DeepTech #RocketPropulsion #ReusableRockets #DefenceTech #AerospaceEngineering #MakeInIndia 

We are excited to announce that Abyom SpaceTech & Defence has officially opened its Commercial Space Infrastructure Test Facility, marking a major step forward in India’s private space ecosystem. Our first external commercial test campaign has been successfully completed in collaboration with the Indian Institute of Technology, Bombay Rocket Team, demonstrating our transition from internal R&D to full-scale commercial propulsion testing operations. The IIT-B Rocket Team partnered with Abyom to validate an M-class #Solid rocket motor. Over two months of preparation, our Abyom’s propulsion, structures, and control-system engineers worked closely with the team to align the motor configuration with the CTF’s operational and safety protocols. The test stand, flame deflector, and sensor interfaces were redesigned to support solid propulsion campaigns, ensuring full compliance with industrial test standards. During the tests, Our in-house #proprietary Engine Control System (ECS) and DAQ modules captured high-fidelity thrust and chamber-pressure data in real time — ensuring repeatability, accuracy, and valuable insight for future propulsion programs, including our next phase of fully #Cryogenic #Reusable rocket engine tests. Our facility is designed with scalability in mind — supporting everything from student-built propulsion systems to high-thrust industrial demonstrators. This collaboration reflects Abyom’s mission to connect academia, industry, and new-space innovators, strengthening India’s growing commercial space landscape and enabling accessible, world-class testing infrastructure. A sincere thank you to the Ministries and programs that funded and backed this vision: India DST, MeitY Startup Hub, Startup India, PIEDS : Pilani Innovation & Entrepreneurship Development Society, BITS Pilani and others. With this milestone, Abyom opens its Commercial Test Facility to external partners, becoming one of the few private entities in #Asia-Pacific offering dedicated propulsion qualification and verification services for startups, universities, and emerging deep-tech ventures. India’s journey toward #reusable launch systems and accessible space infrastructure is one of collaboration — and we’re proud to play a role in shaping that future.
