Hello , aerospace generally means aircraft that stay within earths atmosphere ie. airplanes and helicopter.. whereas aeronautical which stays outside the earth atmosphere which is rockets

all the best

Aerospace engineering is concerned with designing and building aircraft and 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.

Becoming an aerospace engineer involves earning a bachelor's degree in aerospace engineering, and possessing expert knowledge in aero or thermodynamics. Aerospace engineers apply technological theories to the development of various aircrafts. Duties include manufacturing and testing aircraft, space shuttles or weapons. These experts may develop new technologies for aerospace crafts, satellites or missiles, and can specialize in the development of these systems. Aerospace engineers may find themselves working on projects ranging from commercial airplanes to military rockets.

Job responsibilities of an aerospace engineer include:

• Develop and evaluate design plans
• Have prototypes constructed and assessed
• Revise design plans to improve functions
• Assess product safety and standards
• Review problems and determine solutions

Aeronautical engineers specialize in the design and development of planes and other aircraft, and possess expertise in fields such as aeroacoustics or fluid dynamics. They need to have a bachelor's degree in their field or a related engineering field, and earning a license may be required to advance to senior positions. They spend a lot of time working in offices, although they may go to factories and other locations where parts are being manufactured or where aircraft are being assembled as part of their duties. Ensuring that safe aircraft are constructed is a crucial part of their responsibilities, and they need to be very thorough in their assessment of the products they work with in order to identify potential issues or determine why a product hasn't worked properly.

Job responsibilities of an aeronautical engineer include:

• Meet with clients to discuss their needs
• Review design proposals and determine the cost of production
• Modify design proposals to fit a client's budget
• Perform tests to assess the safety of aircraft
• Study product performance issues and recommend solutions
• Determine how to minimize environmental damage from aircraft

Good Luck!
