The Heliopause Observer was an EarthGov colony.
In 2511, prior to the catastrophic outbreak aboard Titan Station, Unitologist regents are due to meet with their counterparts from the Sprawl and the Venus Waypoint on Titan Station to discuss a response to a recent EarthGov "slander campaign" in the media, but it was unknown if this took place due to the local outbreak on Titan Station.
Very little was known about this colony.
- The "Heliopause" is the theoretical boundary where the sun's solar winds are stopped by the interstellar medium, located far beyond the edge of the Solar System. Presumably, the station is located there to monitor this boundary.
