Congratulations on doing well in the challenging aerospace engineering curriculum. You should be proud of your accomplishments and have confidence in your abilities. I recommend that you consider an internship during the summer after your sophomore year. This way, you will have completed some technical coursework and this is a good time to begin considering what you would like to do after you complete your BS degree. Start looking into companies this fall, since many of them will hire in the fall for the coming summer. Also, this leaves you the spring to continue to look, if you can not locate the internship in the fall. Not all internships require programming, so explore multiple opportunities in the traditional aerospace companies, NASA and government laboratories. I wish you the best of luck.
