*All spacecraft that have left Earth orbit for the purposes of
Solar System exploration (or were launched with that intention but failed), including
lunar probes.

*Centuries of terrestrial telescopic observation.
*The great majority of Earth-orbiting satellites.

Uncrewed spacecraft or robotic spacecraft are spacecraft without people on board. Uncrewed spacecraft may have varying levels of autonomy from human input, such as remote control, or remote guidance. They may also be autonomous, in which th ...
