caption_attribution_description: English: Artist's rendering of NASA's Galileo spacecraft flying past Jupiter's moon Io. Galileo made multiple close approaches to the volcanically active moon during its time at Jupiter, including a first pass in Dec. 1995, during its arrival in the Jupiter system.

context_page_description: This is a timeline of Solar System exploration ordered by date of spacecraft launch. It includes:
  All spacecraft that have left Earth orbit for the purposes of Solar System exploration, including lunar probes.
  A small number of pioneering or notable Earth-orbiting craft.
  It does not include:
  Centuries of terrestrial telescopic observation.
  The great majority of Earth-orbiting satellites.
  Space probes leaving Earth orbit that are not concerned with Solar System exploration.
  Probes that failed at launch.
  The dates listed are launch dates, but the achievements noted may have occurred some time later—in some cases, a considerable time later.
