I started the day by downloading 1.9 and a careful persistence file editing so that I could remove Kopernicus without losing anything. After launching the game, I discovered one of my craft had parts from a mod I haven't installed yet for it's not updated to 1.9 yet. After a cautious craft file editing(and being glad said parts were radially attached and didn't have another part attached to them), I managed to remove those parts.
I started the "playing" part of the game by flying my quadcopter on Duna. At first, it was figuratively but it soon became literal when a mountain got in my way. Thankfully, thanks to the magic of revert, nothing was lost.
Then, I switched to my Duna lander and flew Bill around in the small aircraft included in the lander. Jebediah was pretty jealous at first but he quickly calmed down when ground control reminded him that he had his turn the day before and that, anyway, they still have more than a year to fly around before it's time to come back home. Also, it turns out deployed solar panels produce lift, which allowed Bill to push the craft to 60m/s. I'm starting to think Jebediah has a bad influence on the rest of the crew.
Finally, I noticed the fuel depot on my space station wasn't aligned correctly - the modules required to dock my space shuttle would get in the way of craft attempting to dock with that depot - so I made a quick mission to realign it. After docking with the station, I noticed the module was actually aligned the right way so I returned to Kerbin without making any changes to the station.
Unfortunately, while I was getting ready to send another module to the space station, I realized I was wrong: the fuel depot wasn't aligned correctly. Having no choices, I docked with the module again and discovered how "fun" it was to dock something when all the RCS thrusters are at one end of the spacecraft and far away from the CoM.
