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
Famous quotes containing the words space and/or travel:
“For tribal man space was the uncontrollable mystery. For technological man it is time that occupies the same role.”
—Marshall McLuhan (1911–1980)
“There is the grand truth about Nathaniel Hawthorne. He says NO! in thunder; but the Devil himself cannot make him say yes. For all men who say yes, lie; and all men who say no,—why, they are in the happy condition of judicious, unincumbered travellers in Europe; they cross the frontiers into Eternity with nothing but a carpet-bag,—that is to say, the Ego. Whereas those yes-gentry, they travel with heaps of baggage, and, damn them! they will never get through the Custom House.”
—Herman Melville (1819–1891)
