Introduction:
In the predawn hours of June 1, 2024, the serene coastline of Sriharikota, India, was suddenly ablaze with light and thunderous sound. Rising from a private launchpad, a sleek rocket pierced the sky, carrying with it the dreams of a nation and the ingenuity of its brightest minds. This was Agnibaan SOrTeD, the brainchild of space startup Agnikul Cosmos, and its successful launch marked a pivotal moment in India’s space history. As the second privately-built rocket to soar from Indian soil, Agnibaan represented more than just technological achievement – it heralded the dawn of a new era in the country’s space sector.
Key event or challenge:
The journey to this historic launch was far from smooth. Agnikul Cosmos, founded by a team of passionate engineers and entrepreneurs, had set out to democratize space access with their innovative 3D-printed rocket engine. However, the path to liftoff was fraught with obstacles, both technical and regulatory.
“When we started Agnikul in 2017, the idea of a private Indian company launching rockets seemed almost fantastical,” recalls Srinath Ravichandran, co-founder and CEO of Agnikul Cosmos. “We faced skepticism from all quarters. But we knew that with the right technology and perseverance, we could make it happen.”
The company’s first major challenge was developing Agnilet, the world’s first single-piece 3D-printed semi-cryogenic rocket engine. This revolutionary approach promised to slash production times and costs, but it required pushing the boundaries of additive manufacturing technology.
Subject’s journey or product development process:
Agnikul’s team worked tirelessly, often pulling all-nighters in their lab at IIT Madras, where the company was incubated. They iterated through countless designs, testing materials and printing techniques to create an engine that could withstand the extreme pressures and temperatures of spaceflight.
“There were times when we thought we’d hit a dead end,” says Moin SPM, co-founder and COO of Agnikul. “But each failure taught us something new, and we kept refining our approach. The moment we successfully test-fired our first 3D-printed engine was indescribable – we knew then that we were onto something truly game-changing.”
As the engine development progressed, Agnikul also focused on designing the Agnibaan rocket itself. The team aimed for a flexible, modular design that could accommodate a range of payload sizes, from 30 kg to 300 kg, making it ideal for the burgeoning small satellite market.
Obstacles overcome:
With a promising prototype in hand, Agnikul faced its next major hurdle: navigating India’s complex space regulatory environment. The country had only recently opened up the space sector to private players, and the regulatory framework was still evolving.
“Securing approvals for our launchpad and flight tests was a Herculean task,” Ravichandran admits. “We had to work closely with ISRO and IN-SPACe, educating stakeholders about our technology and safety measures. It was a learning experience for everyone involved.”
The COVID-19 pandemic added another layer of complexity, disrupting supply chains and forcing the team to adapt to remote work. Yet, Agnikul persevered, using the time to refine their designs and strengthen their partnerships.
Achievements or innovations:
As 2024 dawned, Agnikul was ready to make history. The company had not only developed a revolutionary 3D-printed engine but had also constructed India’s first private launchpad at Sriharikota. This facility, dubbed ALP-01, represented a significant step towards creating a self-reliant space ecosystem in the country.
The Agnibaan SOrTeD mission itself was a testament to Agnikul’s innovative spirit. The 6.5-meter tall, single-stage rocket incorporated several cutting-edge technologies, including an advanced avionics system and in-house developed autopilot software.
“What sets Agnibaan apart is its flexibility,” explains Prof. Satyanarayanan R Chakravarthy, founding advisor to Agnikul and head of the National Centre for Combustion Research and Development at IIT Madras. “The rocket can be customized for different missions, and its mobile launchpad, Dhanush, allows for launches from multiple locations. This opens up exciting possibilities for responsive space access.”
The successful sub-orbital flight on June 1 validated years of hard work and innovation. Reaching an altitude of 8 kilometers before splashing down in the Bay of Bengal, Agnibaan SOrTeD demonstrated the viability of Agnikul’s technology and paved the way for future orbital missions.
Dr. Pawan Goenka, Chairman of IN-SPACe, hailed the achievement: “The successful launch of Agnibaan SOrTeD marks a historic moment for India’s space sector. Powered by the world’s first single-piece 3D-printed semi-cryogenic engine, this achievement showcases the brilliance of our young innovators and the potential of public-private partnerships in advancing space technology.”

Key takeaways or lessons learned:
Agnikul’s journey from a startup incubated at IIT Madras to launching India’s second private rocket offers valuable lessons for aspiring space entrepreneurs. The company’s success highlights the importance of perseverance in the face of technical and regulatory challenges, as well as the power of innovation to disrupt established industries. Agnikul’s ability to leverage 3D printing technology to create a more efficient and cost-effective rocket engine demonstrates how new manufacturing techniques can revolutionize even the most complex industries. Moreover, the company’s collaborative approach, working closely with government agencies and academic institutions, underscores the importance of building strong partnerships in the space sector. As India’s private space industry continues to grow, Agnikul’s story serves as an inspiring example of what can be achieved through vision, determination, and cutting-edge technology.
