Never did any Soviet Union or US "spacecraft" leave the orbit of the Earth.
So what was the ultimate goal of the pyramid of lies known as Space Travel?

The ultimate goal of the Space Travel Hoax lies beyond the feasibility agenda, i.e. the conquest of the Universe, as proof of godlike illuminati.
The ultimate goal is nothing but a consequence of the BIG LIE technique, the base for illuminati control.
The ultimate goal, now revealed worldwide first, was to produce "evidence" (1) to cover up the hoax at the base of the pyramid of lies:
_ _ _ A _
L _ _ _ I N G

Notes
Soviet Union's Luna 1 "spacecraft" hoax, early 1959, marks the begin of the relevant stage for implementing the ultimate goal.
It did not take long before the first "evidence" supporting the ultimate goal was produced, October 1959, using the Luna 3 "spacecraft" for the Moon.
The process was completed with the the first "evidence" from NASA Voyager 1 "spacecraft" for Jupiter, January 1979.
