My father has published a book, the cover of which is shown above. What is the book about? To paraphrase - the book is not about the science and technology of rockets, nor is it a history of rocket science in India. Rather, it is an exposition of the thought processes and work practices that have made the Indian space effort a success.
Nevertheless, detail is necessary and is presented, because otherwise it would be too "hand-wavy".
Despite all the hype, India is and will remain constrained in resources for R&D for the foreseeable future. Moreover, as noted here by Sunil
From an Indian perspective though, it’s not only the money that needs to increase. The money is very, very important. But, to use a hackneyed scientific phrase, the money is necessary but not sufficient. There is a cultural shift that’s needed to change “mindsets” and re-energize research. There remains a institutional/systemic roadblock to innovation and research in India.,,,
The book says that the Indian Space Research Organization has worked its way around most of those roadblocks, and the message is that this success can be repeated if the lessons learned are taken to heart.
