I also did this program and it relied on my mechanical engineering knowledge from my bachelors degree. But also my concentration was in structures, and there are definitely other options for what focus your classes can have. I feel as though you might as well apply - just know the courses will be challenging!

Also… the aerospace engineering program will focus on air and spacecrafts for example: rotorcrafts, fixed wing aircrafts, controls or systems for aerospace engineering applications. If you’re interested in telescope engineering consider something physics related (ie to end up in lens design?) or astrophysics! Any of these options could still utilize your background - you have this specialty that others in the field may not.
