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.

We are excited to announce that @AbyomSpaceTech & 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 @iitbombay 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: @IndiaDST, @meitystartuphub, @startupindia ,@bitspilaniindia @Boeing and others. With this milestone, Abyom opens its Commercial Test Facility to external partners, becoming one of the few private entities in South #Asia 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. @JainulAbedin37 @isro @DrJitendraSingh @karandi65 @ANRFIndia @tdbgoi @SIDBIVenture @INSPACeIND @YourStoryCo @IndianTechGuide @NewsIADN @idrwalerts @IndiaToday @aajtak @ABPNews @CNBCTV18Live #Abyom #AbyomSpaceTech #SpaceTesting #MakeInIndia #PropulsionTesting #TestedWithAbyom #AbyomxIITBRocketTeam #RocketEngineTesting #IITB #DeepTech #SpaceInnovation #SolidRocketMotorTesting #ReusableSpaceflight

If it’s Impossible then it is definitely possible. I have heard this as a punch line or in a movie but the superstars in the video taught me how it’s done. Kudos to everyone of them. #impossibleisnothing #Rockets #rocketenginetesting @isro @iitmadras @IITMIC @iitmrp

The pace at which this happened is truly mind blowing. We are blessed to have a team of this caliber! Thank you, @AgnikulCosmos crew. You inspire me! #inspiration #rocketenginetesting @iitmadras @iitmrp @IITMIC @startup_mission

And we have phase one done! Terrific work by the crew at an amazing pace! This involved moving, cutting and bending a LOT of metal. The wait for a new Agnite engine to be integrated starts now #rocketenginetesting #rocketengine #Agnite @iitmrp @iitmadras @IITMIC @startup_mission
