Talk is mostly updated and ready for tomorrow (and the following 2 weeks), though I'm sure I will learn things as I go that will necessitate small edits! (Very exciting to parachute down into another country and immediately try to teach stuff to people there)
One edit I'm very happy with is I added a "further reading" slide with books that have really helped me to understand what's happening in orbit and why. #ProfSamLectureTour
