  2. List of Solar System probes - Wikipedia

    en.wikipedia.org/wiki/List_of_Solar_System_probes

    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.

  3. Uncrewed spacecraft - Wikipedia

    en.wikipedia.org/wiki/Uncrewed_spacecraft

    A space probe is a robotic spacecraft that does not orbit Earth, but instead, explores further into outer space. Space probes have different sets of scientific instruments onboard. A space probe may approach the Moon; travel through interplanetary space; flyby, orbit, or land on other planetary bodies; or enter interstellar space.

  4. List of active Solar System probes - Wikipedia

    en.wikipedia.org/wiki/List_of_active_Solar...

    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 ...

  5. Space exploration - Wikipedia

    en.wikipedia.org/wiki/Space_exploration

    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.

  7. List of lunar probes - Wikipedia

    en.wikipedia.org/wiki/List_of_lunar_probes

    This is a list of robotic space probes that have flown by, impacted, orbited or landed on the Moon for the purpose of lunar exploration, as well as probes launched toward the Moon that failed to reach their target. The crewed Apollo missions are listed at List of missions to the Moon. Major programs encompassing several probes include:

  8. Spaceflight - Wikipedia

    en.wikipedia.org/wiki/Spaceflight

    Spaceflight (or space flight) is an application of astronautics to fly objects, usually spacecraft, into or through outer space, either with or without humans on board.Most spaceflight is uncrewed and conducted mainly with spacecraft such as satellites in orbit around Earth, but also includes space probes for flights beyond Earth orbit.

  9. List of space programs of the United States - Wikipedia

    en.wikipedia.org/wiki/List_of_space_programs_of...

    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.
