Hello! There are no definite plans to launch this kind of mission yet, as far as I know. However, the NASA Innovative Advanced Concepts (NIAC) Program has funded studies to examine possible concepts and technologies for a Pluto lander type of mission. One of these studies is investigating how to build a Fusion-Enabled Pluto Orbiter and Lander, and another is investigating how to do a Pluto Hop, Skip, and Jump mission. You can read more about these mission concepts here:

Maybe someday we will get back to Pluto!
