Perpetual Twilight

- Twice a year, near the winter and summer solstices, the orbit of space station nearly parallels the terminator—the fuzzy line separating day from night on the surface below. For a period of about a week, we live in what seems like perpetual twilight, being in neither full daylight nor full night. Our orbit follows the terminator, so that space station is constantly sunlit. From this vantage I can see both day and night simply by swiveling my head from left to right.

- There is a type of social deviate who doesn’t fit in, and who naturally seeks the freedom of the wilderness. The American frontier was settled by that kind of spirit. Ironically, the wilderness of space requires a high degree of social conformity before you are allowed to enter, so today’s pre-selection of candidate explorers effectively requires a different personality type from those who historically ventured into the frontier.
