The act or motion of traveling into, through, and out of space. There is no describable sense of "down" as a direction.
Planets, for example, are not considered "ground", or "down", being as that in the state of space travel, or being in space they are simply spherical masses with a spherical 'gravitational well'.
Space travel is most commonly known by the use of a craft or 'space ship' being that the human bodies are not capable of surviving in space or during space travel.
It is the ability to pilot, move, or drive through open space.
Otherwise, Space travel can refer to:
- Spacefaring, capability of and activity in the art of space travel.
- Spaceflight, the use of space technology to fly a spacecraft into and through outer space, which may include:
- Human spaceflight
- Interplanetary spaceflight
- Interstellar travel
- Intergalactic travel
- Space Travel (video game), an early computer game
