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.
