Inhabitants of Prometheus have mostly been construction crews until replaced by the permanent-party crewmembers. The new habitation module (dubbed "Gauthier Sector" by the construction crews) has a capacity for up to 400 persons, but with the addition of amenities the capacity is estimated to reach 250. The final section of the life-support area is pressurized on 1 September 2169 and 100 specialists will move in immediately to begin with limited operations at the station's research labs. A plaque bearing the names of the first occupants will be placed at the entrance to the module by the R&D Cartel.
The occupants will witness the station shaping up around them. Manufacturing areas will open the following month. The station will be fully staffed and operational within a year.
