saw u link this on DasV channel. the question is lacking detail. technically we already have achieved interstellar travel, voyager is no longer in our system which means its travelling thru interstellar space. if you mean complete an interstellar journey then not a chance within this century, i have doubts it'll ever happen considering the requirements that it would need to travel the 4.2 light years to proxima centauri. Also unless we find a way to see if its worth going we wont be heading out there.
