We've already established it's impossible, without creating a universe-sized-Bible, for God to give the astronaut instructions on how to fly her space ship. But while the morality of space exploration, the ordered science of rockets, the purpose of space travel and the feelings evoked are all found in Scripture so are the boundaries of space travel. Not ethical ones, but actual boundaries from membranes, to political lines, the edge of the Solar system all the way to the edge of the universe. Where one thing actually ends and another begins. God creates and maintains boundaries but also crosses them. Both to mitigate their blurring or to intentionally delete them. This is probably the most abstract of all the ideas in the series but one that's personally important.
