Related, I wonder if there's going to be a postmortem on this mission on the UI, because from the brief scenes when its shown updating or being clicked on, it looks to have a responsiveness on the order of half a second.
It was probably just a cached/saved website saved to the home screen. I'm not a rocket scientist, but as a web developer, I would rely upon that for anything earth-bound, let alone in Space.
...would?
