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.
The mission was designed to study Saturn and its system, including its rings and moons. The Flagship -class robotic spacecraft consisted of NASA's Cassini orbiter and ESA's Huygens lander, which landed on Saturn's largest moon, Titan. [ 11 ]
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.
The Voyager program's discoveries during the primary phase of its mission, including new close-up color photos of the major planets, were regularly documented by print and electronic media outlets. Among the best-known of these is an image of the Earth as a Pale Blue Dot , taken in 1990 by Voyager 1 , and popularized by Carl Sagan, [ 63 ]
Missions to Saturn face competition from missions to other Solar System bodies. The Titan Saturn System Mission (TSSM) was a joint NASA/ESA proposal for an exploration of Saturn and its moons [10] Titan and Enceladus, where many complex phenomena have been revealed by the recent Cassini–Huygens mission.
Saturn and Titan 15 October 1997 1 July 2004 entered orbit: 2452 days (6 yr, 8 mo, 17 d) Mission ended 15 September 2017. Saturn orbiter, performing repeated by-flights of Saturn's moons; also deployed the Huygens Titan lander, the first probe to land on a satellite of another planet. [51] [52] 14 January 2005 Huygens landed on Titan
Institution: NASA; Voyager 1. Mission: investigating Jupiter and Saturn, and the moons of these planets. Its continuing data feed offered the first direct measurements of the heliosheath and the heliopause. It is currently the furthest man-made object from Earth, as well as the first object to leave the heliosphere and cross into interstellar ...
Some moons, minor planets and comets of the Solar System to scale (major planets not to scale) Selected moons, with Earth to scale. Nineteen moons are large enough to be round, and two, Titan and Triton, have substantial atmospheres The number of moons discovered in each year until November 2019. Mercury, the smallest and innermost planet, has ...
