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 ...

NASA's Genesis probe collected solar wind samples at L 1 from December 3, 2001, to April 1, 2004, when it returned the sample capsule to Earth. It returned briefly in late 2004 before being pushed into heliocentric orbit in early 2005.
This list of space telescopes (astronomical space observatories) is grouped by major frequency ranges: gamma ray, x-ray, ultraviolet, visible, infrared, microwave, and radio. Telescopes that work in multiple frequency bands are included in all of the appropriate sections.
The invention of climate research through the use of satellite remote telemetry began in the 1960s through development of space probes to study other planets. During the U.S. economic decline in 1977, with much of NASA 's money going toward the shuttle program, the Reagan Administration proposed to reduce spending on planetary exploration.
(See Other moons of Earth and Quasi-satellite.) Mars has two known moons , Phobos and Deimos ("fear" and "dread", after attendants of Ares , the Greek god of war, equivalent to the Roman Mars). Searches for more satellites have been unsuccessful, putting the maximum radius of any other satellites at 90 m (100 yd).
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 .
