with our current scientific and technological progress, I can say yes we can manage to send such a spacecraft to Proximal Centauri b in the next few decades. But if we found this planet habitable, Which I exclude because this requires several conditions similar to those on earth, how can people with such mass go there? I think this will take several decades if not less than several centuries to acheave this goal.
