Suspended animation in fiction refers to the temporary cessation of life processes experienced by fictional characters, followed by their subsequent revival. This process is commonly employed as a plot device in science fiction narratives. It is frequently utilized to transport a character from the past to the future or to facilitate interstellar space travel, which necessitates an extended journey for months or years. In addition to accomplishing the character's primary objective in the future, they often encounter the unfamiliarity of a new world, which may bear only faint resemblance to their previous surroundings. On occasion, a character is portrayed as possessing skills or abilities that have become lost to society during their period of suspension, enabling them to assume a heroic role in their new temporal setting.

Space travel, or space flight is a classic science-fiction theme that has captivated the public and is almost archetypal for science fiction. 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.
