Why dont you have any doubt about his greatness in scientific field? In scientific field, to prove your greatness, you have to publish research papers. How many research papers he has published? You can say that he was in DRDO, and one is not allowed to publish any paper from there. Then to prove his greatness, he has to show the achievements of DRDO during his period. Almost more than 90% of DRDO projects were big failure. India still depends upon other countries for technology and different parts to build missiles, tanks, etc. He is a great scientist, this impression is totally wrong. Rather, I would say that in Kasturirangan's regime, ISRO's performance was really great. Now India can built and launch its own sattelites. Even recently India has launched sattelites of other countries, including US. Kasturirangan's contribution is, I think, much more than Kalam. Hats off Dr Kasturirangan. He is a scientist in every sense : he has valid PhD degree, he publishes many papers, and he contributed immensely in developing India's space program.
