The number of credits may vary from one institution to another. It could take 60 + credits. However, this is not including the dissertation.

It depends on what your associates degree is in. For nursing and engineering there are 68 credits needed.
Those planning for careers in mechanical engineering typically enroll in engineering programs in college. Courses you can expect to take include calculus, chemistry, and physics.
To receive a degree in civil engineering, you need to complete for years in this discipline. The usual minimum number of credits needed for graduation is 130 credits. However, other colleges could require a different amount above this number.
The usage of trig. in Mechanical Engineering is extensive. Trig. is used in almost every branch of the subject, especially where quantitative answers are needed to real physical problems such as the size of stresses in structural parts or the volume and frequency of a vibration.
you will need a good attitude and open to ideas
All sorts: aerospace, electrical, mechanical, nuclear, etc; it just depends on what you want to do at NASA.
That all depends on where. If we are talking about finding an entry level mechanical engineering job in the US, they currently are hard to find. But jobs for experienced mechanical engineers are considerably less hard to find. As many people say, there will always be a need for mechanical engineers. But mechanical engineering is not exactly 'hot' profession. If you are looking to study mechanical engineering, this is certainly something to keep in mind. The jobs are out there. But there's not an abundance of them. And you may have to relocate to somewhere you would rather not in order to land an entry level mechanical engineering job.
Mechanical Engineering covers it. An undergraduate degree in Aeronautical / Aerospace Engineering would offer most of the Mechanical Engineering syllabus but give you some extra units selected around flight / atmospherics / high speed mechanics etc instead of electives. That could be worth it if you are 110% sure you want to go into Aerospace and wouldn't like the more broad employment opportunities the 'general' Mechanical Engineering degree would give you. Either degree would be fine.
in canada you need 30 credits
122 credits
This that can be saved for energy when needed. Example- food. In mechanical engineering a good example is a spring under tension or a pendulum at the end of it's swing.
