Agnikul ignites India's first electric motor-driven semi-cryogenic rocket engine
Spacetech startup
Agnikul Cosmos
successfully fired India's first electric motor-driven
semi-cryogenic engine
, cofounder and CEO Srinath Ravichandran announced on Friday.
Ravichandran shared a video of the engine being throttled to different levels of thrust by varying the speed of the electric motor.
Electric motor-driven throttling allows for higher accuracy and rapid response, which is important for handling complex trajectories, Ravichandran wrote in a social media post. Also, regarding flight readiness, this test is a key milestone towards firing a cluster of engines together.
The new electric motor-driven system continues to use Agnikul's single-piece
3D-printed engine
, Ravichandran wrote. Along with the patented engine, many subsystems of the pump were also 3D-printed and assembled at the company's Rocket Factory-1 facility, the CEO said, adding that the motor drives and associated control software were also fully designed and developed in-house.

In May last year, Agnikul successfully carried out a
sub-orbital test flight
of its home-built 3D-printed semi-cryogenic rocket, Agnibaan, after several hiccups. The IIT-Madras-incubated company also became India's second private entity after Skyroot Aerospace to launch from a private launch pad.
The rocket used the world's first 3-D printed single-piece engine, dubbed Agnilet. The indigenous engine is a semi-cryogenic unit using sub-cooled liquid oxygen and aviation turbine fuel (ATF).
Talking to ET in October last year, Ravichandran had said that Agnikul will
launch its commercial operations
by mid-2025. The space startup was in active discussions with 30 to 40 potential clients, exploring specific demands and use cases for its
Agnibaan rocket
, cofounder Srinath Ravichandran told ET.
Given the evolving market for small satellite launch vehicles, the company plans to scale its operations to support around 25 launches per year using its mobile launchpad Dhanush at Indian Space Research Organisation (
ISRO
) facilities.

IIT makes learning 1 AI, machine learning course for UG, PG students mandatory
Indian Institute of Technology, Delhi (IIT-D) has recently made at least one course in Artificial Intelligence (AI) and Machine Learning (ML) mandatory for each of the 19 undergraduate and 42 postgraduate programmes. The courses will begin from the next academic session in July, said an administrative official of the institute. This introduction, a part of a larger curriculum review which has taken place after 12 years, is aimed at giving students a 'structured pathway to using AI' and 'keeping up with industry trends'. Each of the undergraduate and postgraduate programmes will have its own AI-related paper. Although some AI and ML courses are being taught at the institute, this is the first time the institute has mandated that every student take these courses. 'Every department has been asked to ensure that there is at least one paper related to AI and ML so that every graduate knows the subject,' IIT-Delhi Director Rangan Banerjee told The Hindu. The initiative has been introduced after taking feedback from students and alumni, he added. The courses vary from 'Introduction to Artificial Intelligence', and 'AI for Computational Biology' to 'Applied Mechanics to Textile and Fibre Engineering in the Engineering Sciences'. Prof. Narayanan D. Kurur, the Dean of Academics, said that students will be taught AI in their respective fields of study to give them an 'introduction to AI'. 'For instance, in the postgraduate course titled 'Machine Learning for Textile and Fibre Engineering', students would be able to apply ML in yarn and fabric engineering and textile chemical processing,' said Mr. Kurur. Associate Dean of Curriculum Prof. Shouri Chatterjee said that students will also be taught how to use AI ethically. 'AI expanding rapidly' 'The scale of AI is expanding rapidly, and students are already working with it. This will give them a structured pathway and show students how to use it productively and ethically,' he said. In 2024, the Director formed a committee to develop guidelines for the use of AI in teaching, research, and examinations. The report, released in October 2024, showed that 80% of students (out of 427 surveyed) have used Generative AI tools, with nearly 81% reportedly using the tools several times a week.
