I had a professor who was an astronaut for four missions, the longest being just shy of 200 days, and on the last day of class he just did a presentation about his time with NASA. He said that, with every minute of his day being scheduled, he and the others needed to find something to pursue, and for him it was taking pictures of all the Navy bases where he'd ever been stationed. So he'd keep an eye on the monitors showing where they were, and every once in a while they'd cross near one of his old bases, so he'd snap a picture. It was pretty cool seeing his overhead pictures and knowing he actually captured them (and not from the screen on Google Earth.) I guess the orbit tracker just reminded me of that presentation.
