This is an artist’s conception of the proposed “Power Tower” space station configuration, shown with the Japanese Experiment Module attached.

Space Tug Elements
Earth Orbit Applications
Lunar Applications
Managed by Marshall Space Flight Center, the Space Tug concept was intended to be a reusable multipurpose space vehicle designed to transport payloads to different orbital inclinations. Utilizing mission-specific combinations of its three primary modules (crew, propulsion, and cargo) and a variety of supplementary kits, the Space Tug was capable of numerous space applications. This 1970 artist’s concept illustrates a Space Tug with an attached landing configuration kit as it prepares for a lunar application. The Space Tug program was cancelled and did not become a reality.
