Reviews of professor David Spencer

Rating: 4.0/5, difficulty: 3.0/5
He's a very smart man that clearly knows what he is talking about, and teaches well. The only reason i'm giving him a 4/5 and not a 5/5 is because although the projects he worked on are impressive, there is no need to constantly bring them up at every lecture.

Dr. Spencer is a great professor! He cares about his students and really teaches well. The insights that he gives to class based on his experience working at JPL is invaluable. The course wasn't very hard, as long as you pay attention in class and review notes, you can get an A on the exams.

I can't speak to what Dr. Spencer was like for a sophomore class like 251. But AAE 590 (Space Flight Operations) was my favorite AAE class I've ever taken at Purdue. It's so rare to find a class that is simultaneously fun, easy, and useful, but this class is it. I would highly recommend anyone who's interested in spaceflight take this course.
