Some people seemed to dislike this class but we really liked it. We had a good group that worked well together and has diverse talents/knowledge coming into the project. We were fortunate enough to have people with backgrounds in computing, astronomy, business, and leadership. Be prepared to work a lot but…it’s really not that bad, just manage your time well. Expect to work more than once a week; we met three times a week and still ran out of time. Even if you think you’re ahead of schedule, don’t take a week off, keep working. Also learn as much about your hardware as much as you can so that when “the sh*t hits the fan” you know how to fix it. Team leader, don’t be afraid to tell your team what to do. Assign them different sections of the DD and make sure they get done when you want them done. Overall this class was a valuable learning experience in more ways than just launching a satellite. And it was fun!
