NASA has recently launched a new application called Eyes on the Solar System. It’s still in beta phase but looks promising, especially in regard to keeping track of current missions.
"Eyes on the Solar System" is a 3-D environment full of real NASA mission data. Explore the cosmos from your computer. Hop on an asteroid. Fly with NASA's Voyager 2 spacecraft. See the entire solar system moving in real time. It's up to you. You control space and time.
