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.
Because of the proximity of the Mars moons to Mars, any mission to them may also be considered a mission to Mars from some perspectives. Past missions Three missions to land on Phobos have been launched; the Soviet Phobos program in the late 1980s saw the launch of Phobos 1 and Phobos 2 , while the Russian Fobos-Grunt sample return mission was ...
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 proposed landing on Ligeia Mare to navigate the lake for 6–12 months. If approved by ESA, it would study the liquid hydrocarbon sea, perform scientific measurements, and explore the surrounding terrain and northern coast of Titan.

Ceased operation on 29 April 2013; will be moved to a heliocentric orbit. [31] [32] Planck Space Observatory Sun–Earth L 2: ESA Arrived at L 2 July 2009. Mission ended on 23 October 2013; Planck has been ...
Musk, undeterred, said the company still plans to launch uncrewed missions to the Red Planet as early as 2026, when the planets' orbits will next align. (Earth/Mars "transfer windows," as such ...
The 52–53-year-old space probe is receding from the Sun at over 43,400 km/h (27,000 mph), [64] Since the start of the Space Age, a great deal of exploration has been performed by robotic spacecraft missions that have been organized and executed by various space agencies.
NASA's Mars Exploration Rover Mission (MER), started in 2003, was a robotic space mission involving two rovers, Spirit (MER-A) and Opportunity, (MER-B) that explored the Martian surface geology. The mission's scientific objective was to search for and characterize a wide range of rocks and soils that hold clues to past water activity on Mars.
