Propellant Transfer

Conceptual view of the operations in the equatorial earth orbit. The operation in orbit is principally one of propellant transfer and it not an assembly job. The vehicle being fueled is the third stage of a SATURN II with a lunar landing and return vehicle attached. The third stage of the SATURN II was used in the combination into orbit and has thus expended its propellants. This stage is fueled into orbit by a detachment of approximately ten men after which the vehicle then proceeds on the moon.

Convair Migrator

An ad in a 1962 issue of Missiles & Rockets magazine describes this concept as a multi-purpose concept designated “Migrator.” Beginning in 1968, it could serve as a highly versatile, operational space station. “Migrator” will contain an onboard propulsion system, giving the vehicle the capability to migrate from one operational site to another, and will offer extended usefulness by serving as an interplanetary spacecraft.
