A Question About Trade Cities


So I’ve been examining the requirements for a Trade City: 5 active members, 25k Credits, Decent Cityscape, Docking/Landing Zones, and a Taller Trade Building.
It never actually specifices WHERE the city is located. So here’s my question:
If it fulfills all of the above requirements, can a trade city be established in space? (Like a space station)


Uh, the 5 active members, and 25k credits has to be in your SETTLEMENT info screen. The trade city must be located in your settlement.
