Off hand (I'll probably overlook some):
The Juno orbiter is circling Jupiter. They are still welcoming the public to discuss/vote on what parts of Jupiter they should photograph on each pass:

We have that big Mars rover. Also, one of the two older medium-sized rovers is still going.
The Dawn orbiter is still orbiting Ceres in the asteroid belt.
The probe that shot past Pluto will pass close by a large Kuiper Belt Object in 2019.
The old Voyager probes are well past any major discoveries, but they are giving us our first readings of interstellar space.
I believe this is the most recent planning for future missions:

They break their missions up into small, medium and large. The top three large missions in their future plans are:
a) something that will land on Mars, package up soil samples, and launch them back to earth for study
b) an orbiter around Jupiter's moon Europa (believed to have a liquid water ocean under the ice that could hypothetically harbor non-earth life)
c) a Cassini-like orbiter/probe for Uranus
