The future of space exploration involves both telescopic and physical explorations of space by robotic spacecraft and human spaceflight. Near-term physical exploration missions, focused on obtaining new information about the Solar System , are planned and announced by both national and private organisations.
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.
"NASA stated cost increases, delays to the launch date, and the risks of future cost growth as the reasons to stand down on the mission." NASA announced they would consider "expressions of interest" from industry to use the "VIPER rover system at no cost to the government". In October 2024, VIPER passed all pre-launch tests.

The timeline of discovery of Solar System planets and their natural satellites charts the progress of the discovery of new bodies over history. Each object is listed in chronological order of its discovery (multiple dates occur when the moments of imaging, observation, and publication differ), identified through its various designations (including temporary and permanent schemes), and the ...
Solar System space probes operational as of November 2024. This is a list of active space probes which have escaped Earth orbit. It includes lunar space probes, but does not include space probes orbiting at the Sun–Earth Lagrangian points (for these, see List of objects at Lagrangian points). A craft is deemed "active" if it is still able to ...
Moon: Success: Queqiao-2 relay satellite for far side of the Moon with Tiandu-1 and 2 to test future lunar satellite constellation technologies. China: Chang'e 6: Moon: Success: Orbiter, Returner, Ascent Stage, Lander, Rover configuration mission, China's first automated return of samples from the far side of the Moon. orbiter visited L2 ...
A subsatellite, also known as a submoon or informally a moonmoon, is a "moon of a moon" or a hypothetical natural satellite that orbits the moon of a planet. [3] It is inferred from the empirical study of natural satellites in the Solar System that subsatellites may be rare, albeit possible, elements of planetary systems. In the Solar System ...
In January 1986, Voyager 2 became the first spacecraft to visit Uranus. During its flyby, it discovered 10 new moons, 2 new rings, and a magnetic field tilted at 55 degrees off-axis and off-center. In August 1989, Voyager performed its last flyby, going by Neptune and visiting its moon Triton.
