Space travel,[1]: 69 [2]: 209–210 [3]: 511–512 or space flight[2]: 200–201 [4] (less often, starfaring or star voyaging[2]: 217, 220 ) is a classic science-fiction theme that has captivated the public and is almost archetypal for science fiction.[4] Space travel, interplanetary or interstellar, is usually performed in space ships, and spacecraft propulsion in various works ranges from the scientifically plausible to the totally fictitious.[1]: 8, 69–77
While some writers focus on realistic, scientific, and educational aspects of space travel, other writers see this concept as a metaphor for freedom, including "free[ing] mankind from the prison of the solar system".[4] Though the science-fiction rocket has been described as a 20th-century icon,[5]: 744 according to The Encyclopedia of Science Fiction "The means by which space flight has been achieved in sf – its many and various spaceships – have always been of secondary importance to the mythical impact of the theme".[4] Works related to space travel have popularized such concepts as time dilation, space stations, and space colonization.[1]: 69–80 [5]: 743
While generally associated with science fiction, space travel has also occasionally featured in fantasy, sometimes involving magic or supernatural entities such as angels.[a][5]: 742–743
