Starbase 173
From Star Trek: Theurgy Wiki
Starbase 173 was a Federation starbase operated by Starfleet during the mid-24th century.
When Benjamin Sisko was a sophomore at Starfleet Academy, he performed his field study at this starbase. He was "a little apprehensive" upon arriving, but later came to regard his time there as one of the best experiences of his life. (DS9: "The Ascent")
In 2363, a medical officer who had served at the starbase for the last fifteen years died in a tragic accident. The officer was the legal guardian of Thomas Ravon. Afterwards, Federation guardians took the boy in.
In 2362 a pre-Academy education program for Starfleet dependents was started at Starbase 173. Thomas Ravon started school at age five and enrolled in the pre-Academy education program at the age of fourteen. Thomas Ravon spent his first fifteen years at Starbase 173, and the Federation guardians that had taken the boy in ensured that he could enrol at Starfleet Academy at age seventeen.
