SPACE OPERATIONS CENTER[BOEING]
Notes:
The Space Operations Center was proposed by NASA's Johnson Spaceflight Center in 1979. Unlike most previous space station designs, its primary mission was the assembly and servicing of large spacecraft in Earth orbit -- not science.
NASA/JSC signed a contract with Boeing in 1980 to further develop the design. This illustration is from 1981. Like most NASA space station plans, SOC would be assembled in orbit from modules launched on the Space Shuttle. The Shuttle depicted here delivers a resupply module for the SOC crew; the tour of duty would have been 90 days.
