But wait! There's more. One of the products from Stellagama Publishing, known for their support for the Cepheus Engine, is Near Space. Near Space has nine subsectors around Sol with scientifically accurate data on exosolar planets.
Another GURPS Traveller title, First In gives everything to know about the Scouts and exploration. How do you scan and chart a system? It also has an enhanced star and world generation system that provides additional details from the standard Traveller UWP.
I'll be using the Near Space maps and physical planetary data, pulling some specific planet details from Interstellar Wars, and then filling in the system details using First In's star generator.
