Dear friend, Its really good news that people from new generation are interested in research field and don't want to stuck up in some job or also not attracted towards MNC.
The IIST is Asias first space university and the only one in the world to offer courses from undergraduate to doctoral level in space science and technology. The students passing out of IIST with minimum specified academic performance will be absorbed in ISRO as scientists/engineers. An assistanceship package is offered by department of space for all the B.Tech students to cover the complete cost of education, boarding and lodging.
You can also do PhD in any of the three subjects which interests you more. Attaining PhD degree is the most valuable in research filed. If you want to join ISRO after doing MSc, you can apply there also after giving an entrance exam.
IISc is well knowned for its research work. You can give KVPY, or JEE Advanced to be eligible for IISc.
All the best
Hope this helps
