The best course ever.! it really has the scientific detail that you do not find anywhere else in a clear simple and didactic way. The instructor is an amazing educator.

Incredible Resources, But A Bit Monotonous Which Sucks Out The Enthusiasm To Complete The Course. But Make No Mistake, This Is One Brilliant Course And You *MUST* Try This To Understand The Universe Around You A Little Better.

Definitely learned a lot but the exercises could have been a bit more involved.

It's also too easy to get away with submitting blank essays, but I suppose that's to the loss of the student.

It was nice and well done. LAcks perhaps of explining exercises and solving problems. I don+t know if there is a certificate...

This course was not a good fit for me. Too much math (I really didn't know the derivation of every equation to get the gist of the information) and I did not really find the subject matter truly engaging until the last 3 weeks or so.

Aside from my personal issues with the course, I do not think it is suited to a MOOC format. The slides shown during the lectures were very hard to read, especially the ones with white backgrounds. Some of the questions pertained specifically to the day the lecture was given ("What planets are in the sky tonight?" can only be answered if you know what day the question was asked!) and some of the information outlined is now out of date. Most importantly, all of the grading in this class is done by peer-review. It's hard to do that unless there is a group all taking the class at the same time. A rolling enrollment MOOC is just not a good fit for this class.

Sorry Professor David>>>your presentation on the 'dark streaks' on Mars' crater sides is outdated. I personally have studied these some 10 years ago having followed the 3 rovers and the lander 10 years ago and watched the water sublimate from the Phoenix digs, at that point I knew 'instinctively' that the dark lines were sand. Please see NASA link above.

I can not continue your course for the obvious reason that some other data will be outdated.

However, I truly have enjoyed your presentation method and if and when your updates to other lectures are complete I will endeavor to complete the lecture course.

Thank you.

The lectures are informative but too long and fail to keep the listeners interested. Overall very knowledgable for anyone interested in astronomy.

Something is broken in the course software - only the first week's page shows up, and that with the wrong course name.
