This blog post on the issues involved for a Muslim in low-earth orbit needing to determine the direction of Mecca is fascinating by itself (and, obviously, it's more of an issue for those in orbit -- when different directions face different parts of Earth -- than from other galaxies, when one must simply determine the direction of the Milky Way).
