     exploration (or were launched with that intention but failed), including lunar probes.
  • A small number of pioneering or notable Earth-orbiting craft.


It does not include:
  • The great majority of Earth-orbiting satellites.
  • Probes leaving Earth orbit that are not concerned with Solar System exploration (such as space telescopes targeted at distant galaxies, cosmic background radiation observatories, and so on).
  • Probes that failed at launch.


The dates listed are launch dates, but the achievements noted may have occurred some time laterin some cases, a considerable time later (for example, Voyager 2, launched 20 August 1977, did not reach Neptune until 1989).

Missions in italics are unfinished, i.e. have not yet been designated as successes or failures. Some unitalicised missions are nevertheless still operational, some in mission extension phases.
