Big dilemma. Comparing Govt job and research is not actually relevant.
Please clarify your educational qualifications and work experience if any.
Research as a career is a good option, if you have the perseverance and inclination towards research/teaching, innovation, then you can go for research institution job opportunities.
If you wish to have a more secure, less innovative, less hectic lifestyle, want stable monthly income etc. then government job is recommended.
You will have to select based on your personal inclination and interest. However both are good opportunities.
Nice to know your inclination for become a researcher in the engineering operations field.
For this, after BTech, I would strongly suggest you to complete Masters (MTech) from a good Institute/University and you can take Operations also a specialisation in Masters. Doing a Masters would be very essential for your future career growth since this is a minimum qualification for doing a formal research as PhD. PhD in Operations is very good as far as the industry is also concerned.
If age permits you can also do PhD as a JRF in a recognised University.
Alternatively you can opt for
I have no clues whether defence doers provide engineering student with project work.
But I like to support unique and innovative ideas.
So I would suggest, contact the DRDL office with a complete ready plan of your project.
Probably seeing your keen interest they may give you a chance.
Wish you good luck............
Interesting to see your interetst in Space and researdch followed by joining NASA.
But honestly, space science and research centres are basically Research oriented centres and hence requires someone with atleast a masters degree and who wishes to pursue a P.HD further in areas related to astronomy or space science etc.
After 12th, you would have to pursue either an engineering degree and further it with a masters in engineering. especially astronomy and space science.
As far as NASA is concerned,. generally researchers at an advanced stage or with many years of experience are r
