A device or vessel designed for space travel is a spacecraft.

Martin Rosado

 A spacecraft is a machine it may or may not be intended to return to the Earth, even though it is by definition constructed to journey into space. Communications, earth observation, meteorology, navigation, planetary exploration, and space tourism are just a few of the uses for which spacecraft are utilised. The crew and passengers on board human spaceship are all humans. Robotic spacecraft either operate autonomously or via tele robotics. Space probes are autonomous spacecraft that travel beyond a planetary body. Artificial satellites are robotic spacecraft that continue to circle a planet. Starships that were designed for interstellar travel are still merely theories. Science fiction frequently features spacecraft and the extremities of space travel.
