The closest thing is new horizons. However, due to some complications with the department of energy, there no longer exist RTGs (the nuclear-decay power source) of the kind that are used to power Voyager. New Horizons has an RTG, but it's much smaller capacity and will degrade much faster, so it's unlikely that NH will provide the same long term results as V1 & V2.
