Trading with Terran's
You can trade with the Terran's from the start of any new game without having to unlock anything. To get to Terran space you must travel to Heretic's End (13, 4) and look for the north gate (coordinates -5.7km, 0km, 87.5km). This will lead you to Alpha Centauri - the first Terran sector.The Terran's don't use energy cells to power their stations, but Fuel cells. So bare this in mind when trading. You can trade with all Terran station, including the Terran Special Shield factory in the Sol System (not in custom starts postions - sorry I forgot to add it to them).
The most important Terran sector - The sol system (12, 2) contains a working shipyard and equipment dock. You may even buy the Terran Aurora from the shipyard in The sol system. The shipyard is somewhat hidden, but you should find it at coordinates -21.2km, 7.5km, 85.6km.
