Early Program Development. NASA public domain image colelction.

This 1969 artist's concept illustrates the use of three major elements of NASA's Integrated program, as proposed by President Nixon's Space Task Group. In Phases I and II, a Space Tug with a manipulator-equipped crew module removes a cargo module from an early Space Shuttle Orbiter and docks with it. In Phases III and IV, the Space Tug with attached cargo module flys toward a Nuclear Shuttle. As a result of the Space Task Group's recommendations for more commonality and integration in the American space program, Marshall Space Flight Center engineers studied many of the spacecraft depicted here.
