The Agnibaan SOrTeD Launch

Launch Details

On May 30, 2024, at 7:15 am, Agnibaan SOrTeD lifted off from Sriharikota, successfully completing its mission objectives. The rocket’s vertical ascent and performance were closely monitored, validating the technology for future orbital flights.


This launch marks a significant milestone for India’s private space sector, demonstrating the viability of privately developed rocket technology and paving the way for future commercial launches.

Technical Specifications

The Agnibaan SOrTeD is a single-stage launch vehicle powered by Agnikul’s Agnilet engine. The engine is entirely 3D-printed and uses a semi-cryogenic fuel mix of aviation turbine fuel and liquid oxygen.




The Role of Additive Manufacturing

3D Printing Technology

Additive manufacturing, or 3D printing, has revolutionized the way rocket engines are built. Agnikul’s use of this technology allowed for the creation of a single-piece engine, reducing complexity and production time.


3D printing enables rapid prototyping, customization, and cost savings. The technology also allows for intricate designs that are not possible with traditional manufacturing methods.



Agnikul’s engine, Agnilet, is the first of its kind to be 3D-printed in a single piece. This innovation significantly reduces quality testing time and enhances reliability.



Overcoming Challenges

Technical Glitches

The road to success was fraught with technical challenges. The Agnibaan SOrTeD launch faced four aborted attempts due to various glitches, each serving as a learning opportunity.



The team’s resilience and problem-solving skills were crucial in addressing these issues and ensuring the eventual success of the launch.

Team Efforts

The young engineers at Agnikul, with an average age of 23, demonstrated remarkable patience and determination, underscoring the importance of teamwork in overcoming challenges.




The Significance of Semi-Cryogenic Engines

What They Are

Semi-cryogenic engines use a combination of cryogenic (very low temperature) and room temperature propellants. They offer high efficiency and thrust compared to conventional engines.


These engines are more efficient and cost-effective, using readily available fuels like kerosene and liquid oxygen. They also reduce the environmental impact due to their cleaner combustion process.

Comparison with Other Engines

Compared to solid or fully cryogenic engines, semi-cryogenic engines offer a balanced approach, combining the benefits of both types while mitigating their drawbacks.




Achievements and Milestones

Firsts for Agnikul Cosmos

Agnikul has achieved several firsts, including the development and successful test of India’s first single-piece 3D-printed semi-cryogenic engine and the establishment of the first private launchpad in India.


These accomplishments have garnered significant attention and recognition from the global aerospace community, highlighting India’s growing capabilities in space technology.

Future Prospects

With these achievements, Agnikul is well-positioned to become a leader in the global small satellite launch market, providing cost-effective and reliable launch solutions.




The Role of IIT-Madras


Agnikul Cosmos was incubated at IIT-Madras, which provided critical support in the form of infrastructure, mentorship, and funding.


The institution’s resources and expertise were instrumental in the start-up’s development, particularly in the early stages when securing external funding and validation was challenging.
