I didn't see a topic for these courses , so I thought I'd post a link. I've taken a couple of edx courses and they are pretty amazing, especially considering that they are free. Both classes start in Feb.
The Conquest of Space: Space Exploration and Rocket Science Explore the history of space travel and learn the basics of aerospace engineering.
Space Mission Design and Operations Learn the concepts used in the design of space missions, manned or unmanned and operations, based on the professional experience of the lecturer.
"You will learn from the experiences of Claude Nicollier, one of the first ESA astronauts, specifically, his role in the maintenance of the Hubble Space Telescope with NASA."
From my experience the course effort estimates are pretty accurate and the online materials are engaging. The presenters are very good and sometimes rock stars in their field. I think it will be fascinating to see how the mission design course compares to KSP gameplay.
