A Boeing design study for a Mars exploration probe, 40 ft. in diameter and weighing 600 lb. Assembled and launched at a space-station, the unmanned probe would draw its power from the Sun. Propelled by an ion rocket, it would take three years to orbit Mars and return.

A Boeing design for a manned orbital or interplanetary reconnaissance vehicle. The vehicle would be built in orbit around the earth around the Earth, inside a plastic bubble having controlled atmosphere and pressure, permitting technicians to work without space suits. Propelled by a nuclear-powered plasma jet, it could travel to planets within our solar-system , carrying shuttle vehicles to make the actual observations of planet surfaces. Nylon nets, rather than flooring, would divide the vehicle into seven levels.
