This dimension groups spacecraft by the era in which they launched. Wikipedia notes that "only a handful of interstellar probes, such as Pioneer 10 and 11, Voyager 1 and 2, and New Horizons, are on trajectories that leave the Solar System," probes that themselves span several decades of launch history. Browsing by launch era lets a visitor compare spacecraft flown in the same period.
