Who work on the rocket-propelled vehicles, they apply the principles of Mathematics, Physics, and Material Science to solve challenges related to these vehicles. Rocket Scientists are involved in the process of design and development of the vehicles such as small drones, satellites, and commercial aeroplanes.

Yes, this field is considered hard. It is complex and demands high precision. There can be extreme consequences for minor errors. The overall field is extremely challenging as it requires to apply the basic scientific principles to design and develop rockets. It requires sophisticated engineering with careful material selection, and allows narrow margin for error.

The following are the qualification which can help you to become a rocket scientist:

·       Bachelor's Degree such as B.Tech/B.E can take up to four years to complete.

·       You can do a two years Master's Degree M.Tech/M.E./M.S. after graduation.

·       For advanced level study in this field, you can also do Ph.D and Research.
