SASSTO (Saturn Application Single-Stage-to-Orbit) combined launch vehicle and spacecraft. Only 62.3 ft (19m.) tall, a single plug-nozzle engine would serve both as launch vehicle and for soft-landing back on Earth after an orbital mission. The craft – seen here with a Gemini two-man capsule – would be recovered intact and could be used repeatedly. It would be a particularly appropriate for ferry missions into Earth-orbit including the emergency rescue of astronauts.

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.

The Saturn V configuration is shown in inches and meters as illustrated by the Boeing Company. The Saturn V vehicle consisted of three stages: the S-IC (first) stage powered by five F-1 engines, the S-II (second) stage powered by five J-2 engines, the S-IVB (third) stage powered by one J-2 engine. A top for the first three stages was designed to contain the instrument unit, the guidance system, the Apollo spacecraft, and the escape system. The Apollo spacecraft consisted of the lunar module, the service module, and the command module. The Saturn V was designed perform lunar and planetary missions and it was capable of placing 280,000 pounds into Earth orbit.
