India’s young space entrepreneurs are charting new paths in the sector.
The offices of Bellatrix Aerospace in Bengaluru may seem unassuming, especially when you are told that six young engineers here developed a water-powered, electric propulsion system for satellites. Indian Space Research Organisation has given the company a developmental order for this system. Bellatrix is also working with Hindusthan Institute of Technology, Coimbatore, to develop a micro-satellite that will be in orbit in the near future.
CEO Rohan Ganapathy, 25, says it all began the day he met Buzz Aldrin, the second man on the moon, in the US in 2011: “I was still in college in Coimbatore, when I got an opportunity to attend a seminar organised by NASA. Aldrin told me that that there is huge scope in space exploration and technology, as a large part of space is still unexplored. Though I was always interested in space sciences, that day fixed my goal. I knew I had to do something unique in this field.”
Ganapathy says his second wave of inspiration also came from the US. When private firm SpaceX built its own rockets, he felt it could be done in India, too. “I knew that space projects are long term, require immense dedication, patience and, more than anything else, huge funds,” he said. Among his earliest mentors he counts Sajjan Jindal, chairman, JSW Group, Dr P.S. Goel, former director, ISRO Satellite Centre, Bengaluru, and Dr Ugur Guven, a renowned aerospace and nuclear engineer.
Propulsion systems help satellites reach and maintain orbit. “Most of the current satellites today use chemical propulsion systems, in which fuel constitutes the major part of satellite mass,” Ganapathy said. “Since combustion of fuel is involved, these thrusters carry significant risk. On the other hand, electric propulsion systems consume less fuel, are far more efficient and cost effective. Using an electric propulsion system, the same satellite can carry three times the payload.”

We need to engage more with communities
Designer Aratrik Dev Varman of the label Tilla has long been a lover of history. One could comfortably call him part-aesthete, part-archeologist, for his clothes dip into vintage styles of the Kutch, Sindh, Balochistan and Afghanistan, bringing alive antique styles and crafts. Tilla, the store and atelier, are situated on a tree-lined avenue in Ahmedabad.
The great luxury slowdown
A year or so ago, if anyone had told me that Tommy Hilfiger would have stolen the show at New York’s Met Gala, I would have laughed. But it seems the end of giant luxury labels is upon us even before we expected it. The American ready-to-wear designer Tommy Hilfiger seems to have created the maximum media buzz at the 2024 Met Gala, according to several data analytics firms.

Employability issues are a narrative created by the corporate world
Prof Yogesh Singh is the 23rd vice chancellor of the century-old University of Delhi (DU). An engineer with a PhD in computer engineering, Singh has an impressive track record of teaching, innovation and research in the area of software engineering. He has more than 250 publications and his book, Software Testing, published by the Cambridge University Press, is well-received internationally. In an interview with THE WEEK, Singh talks about trends in higher education in India, the challenges faced by big universities, and how to make higher education more interesting. Asked about the perception that Indian graduates are “not employable”, he reacts strongly, and emphasises the difference between training and higher education. Edited excerpts:
