Regarding linking icons and descriptions: perhaps a thin outline around each symbol in the chart and in description boxes - a different color for each station orbiting a given body? I.e. Paradise and Heaven could get green and blue respectively. You could re-use colors across the various bodies, since it's already visually clear that (for example) Joshua Complex and Heaven are associated with different bodies. So both could be blue if necessary.

Hope it's clear what I mean. Just a suggestion.
