    Montage of planets and some moons that the two Voyager spacecraft have visited and studied. It is the only program that visited all four outer planets. A total of nine spacecraft have been launched on missions that involve visits to the outer planets; all nine missions involve encounters with Jupiter, with four spacecraft also visiting Saturn.

    en.wikipedia.org/wiki/List_of_proposed_missions...

    The list of proposed missions to the outer planets is a listing of concept studies for an uncrewed or crewed mission to gas giants. Proposed missions to gas giants are typically based on engineering and scientific assessments of technological capabilities at the time of study.

  4. List of Solar System probes - Wikipedia

    en.wikipedia.org/wiki/List_of_Solar_System_probes

    This is a list of space probes that have left Earth orbit (or were launched with that intention but failed), organized by their planned destination. It includes planetary probes, solar probes, and probes to asteroids and comets, but excludes lunar missions, which are listed separately at List of lunar probes and List of Apollo missions.

  5. Voyager program - Wikipedia

    The main objective of the VIM was to extend the exploration of the Solar System beyond the outer planets to the heliopause (the farthest extent at which the Sun's radiation predominates over interstellar winds) and if possible even beyond. Voyager 1 crossed the heliopause boundary in 2012, followed by Voyager 2 in 2018.

    This is a list of all spacecraft landings on other planets and bodies in the Solar System, including soft landings and both intended and unintended hard impacts.The list includes orbiters that were intentionally crashed, but not orbiters which later crashed in an unplanned manner due to orbital decay.

  8. Grand Tour program - Wikipedia

    en.wikipedia.org/wiki/Grand_Tour_program

    In 1969, NASA created the Outer Planets Working Group, which favored the concept of two missions that would visit three planets each (including Pluto, which was considered a planet at the time). These missions were referred to as the Grand Tour. One would launch in 1977 and visit Jupiter, Saturn, and Pluto, while the other would launch in 1979 ...

    Mission: studying all four giant planets. This mission was one of NASA's most successful, yielding a wealth of new information. As of November 2017 it is some 116 AU from the Sun (17.34 billion kilometers). [14] It left the heliosphere and crossed into interstellar space in December 2018.
