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.
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 ...
Space programs of the United States date to the start of the Space Age in the late 1940s and early 1950s. Programs involve both crewed systems and uncrewed satellites, probes and platforms to meet diverse program objectives. From a definition perspective, the criteria for what constitutes spaceflight vary.
An enduring mystique surrounds the Voyager 1 and 2 probes. Launched two weeks apart in 1977, the twin probes changed the way we see our solar system, sending back stunningly detailed views of ...
Government space agencies, established by governments of countries and regional agencies (groupings of countries) are established as a means for advocating for engaging in activities related to outer space, exploitation of space systems, and/or space exploration. The listings summarize all countries' and regional authorities' space agencies ...
A space probe is a scientific space exploration mission in which a spacecraft leaves Earth orbit and explores space. Subcategories. This category has the following 13 ...
Space exploration is the use of astronomy and space technology to explore outer space. [1] While the exploration of space is currently carried out mainly by astronomers with telescopes, its physical exploration is conducted both by uncrewed robotic space probes and human spaceflight.
This is a list of proposed space probes that are planned to focus on the exploration of the Solar System, ordered by date of spacecraft launch. Launched probes are in the List of Solar System probes and the List of active Solar System probes .
