Good point and that's an oversight - I had made an earlier version and wanted to update it with the latest mission photos. She very much enjoyed playing with the original but had trouble making it do what she wanted and had some suggestions. Over the last couple of weekends we made a new design (mostly her) and wrote some code (mostly me) but we talked about things like lat/lng and how they can be used to position a point on earth, the math code (at a high level) needed to convert them so they appear on the screen - that sort of thing. She's such an interested, engaged little thing that she appeared to love every minute of it - warmed my heart.
