halacha - When does somebody living in space (e.g. ISS) observe Shabbat?


I understand that Jewish astronauts have been advised to observe Shabbat by Cape Canaveral time, by analogy with traveling to a place that doesn't have daily sunrise/sunset where some rule you use the last place you were that did. But this seems to describe a temporary journey, such as a shuttle flight. What is the rule if one is living in space for an extended time? Edit: Would each individual determine his own time (if it's based on home/departure city), or would the community living there determine a time together to reduce the chaos of varied Shabbat times in the same place?


(This is related to this question and this question, but these questions are about earthly sunset-less days, which might be different.)
