However, the name originates from, and can describe a more elaborate set of spacefaring hardware in the 1970s, although this meaning is obscure.

The Space Transportation System (STS) is another name for the NASA Space Shuttle and Space Shuttle program. However, the name originates from, and can describe a more elaborate set of spacefaring hardware in the 1970s, although this meaning is obscure. For example, there was at one time a Mars exploration program called Voyager, but this was later obscured by the Voyager program, which launched two planetary space probes.
The other STS was a system of reusable manned space vehicles envisioned by NASA in the early 1970s to support extended operations beyond the Apollo program. Its major components consisted of an Earth Orbit Shuttle; a chemically-propelled "space tug" which could be used for low-to-high Earth orbit or Earth-to-lunar orbit transfers, and as a lunar orbit-to-surface shuttle; and a nuclear-powered interplanetary shuttle vehicle for flights to the planets Venus and Mars. The transportation system would support, and in turn be supported by, Earth and lunar orbital space...
