For about the first 700 years the patrol was in operation, HQ was situated on Earths moon.

But the vast distances covered was quite a drain on the budget, and then with the development of the Jackson/Mackalin drive we were able to cover more territory.

This also brought about the need for more trained troops & pilots, so extending the patrol and creating more jobs.
This is is the view one gets approaching the station on Tarris Moon.

Worked in PS, Artmatic & Bryce and inspired by great scifi works.
