XZ49 was a research station in the 21st century.

When the Third Doctor visited Zoe Heriot on the station, Benedict Sheerstock was the director and Bosmial was the assistant director. Sandra Urtiman and Professor Akermore were research team leaders.

Over a decade later, Xafta was the director. Dr Urtiman and Zoe were still working on the station. (PROSE: The Tip of the Mind)
