Aerospace Engineering

Hi
The choice has to be always made by you as the course and the job both will be done by you as per your interest. Just to help you in making decision, here is the description of both.
Aerospace engineering is concerned with designing and building aircraft and spacecraft. Aerospace engineering can be divided into two specializations: aeronautical engineers, who handle aircraft, and astronautical engineers, who design spacecraft.
A bachelor's degree in aerospace engineering would likely include both specializations, whereas a bachelor's degree in aeronautical engineering would focus solely on those vehicles that fly within the Earth's atmosphere. Both options usually require students to take some similar courses, like dynamics, propulsion and fluid mechanics
Hope this helps you in making decision.

A degree in aerospace engineering and a degree in aeronautical engineering both prepare students to design aircraft. In fact, aeronautical engineering is a branch of aerospace engineering. Astronautical engineers are individuals that have a keen academic interest in aviation, aircraft and flight technology; Astronautical engineers are specialized aerospace engineers that are responsible for designing, developing and testing vehicles and equipment that operate outside of the earth's atmosphere.
Astronautical engineers may be responsible for conducting basic and applied research in order to determine whether or not certain materials and equipment adapt well to aircraft design and manufacture.
