Where in space did the voyager space mission go?

If this question refers to the Voyager program, the answer is, we don't know yet. Both the program, and the two deep space probes Voyager 1 and 2, are still on-going.

Both probes have enough electrical energy that they are estimated to be able to continue operating to about 2020. At this point, the program will most likely close down, but the probes will still continue travel on a ballistic trajectory, and where they will end up is anyones guess.
