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.

Thorough, lengthy, weeks-long grounding in the subject. Only problem is stupid peer review.

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your presentation on the 'dark streaks' on Mars' crater sides is outdated.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I can not continue your course for the obvious reason that some other data will be outdated.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.
