The most memorable zero-gravity sex scene is arguably the one in The Expanse: it makes floating intimacy legible, then abruptly ends it when the ship’s thrust restores gravity. Other standouts range from Moonraker’s campy space-station flirtation to Barbarella’s iconic weightless undressing. This is an editorial selection, judged by how clearly each scene conveys weightlessness, its visual inventiveness, its comic or dramatic payoff, and its cultural recognition. “Sex in space” is used loosely here: some scenes show floating, some take place in a gravity chamber or reverse-gravity room, and others are set in space without clear zero-g mechanics.
The Expanse (season 1, episode 1, “Dulcinea”)
For a scene that combines clear zero-g movement with a sharp narrative interruption, the pilot of The Expanse is the strongest pick. James Holden and Ade float together aboard the Canterbury; when the ship’s engines engage, thrust restores gravity and breaks up the encounter. Syfy’s scene coverage identifies the characters and the shift that ends the moment.
The scene’s gravity has a specific fictional mechanism. In a later discussion of the show’s science, co-creator Daniel Abraham distinguishes first-season thrust gravity from the spin gravity used in a season-two setting, where rotation creates centrifugal force. Those are separate effects, not interchangeable explanations for the pilot.
The floating was staged with wires, harnesses, and choreography. Steven Strait, who plays Holden, told The Hollywood Reporter—as quoted in CinemaBlend’s report on filming weightless sex scenes—that small movements had to feel delicate because the imagined environment offered no resistance. That production detail helps explain the scene’s controlled motion; it is not evidence about how people would behave during actual sex in space.

Moonraker (1979)
James Bond and Holly Goodhead’s attempted romantic encounter aboard a space station turns the franchise’s space-age extravagance into a punchline. The scene is memorable less for plausible orbital mechanics than for its campy spectacle and the audacity of placing Bond’s seduction routine in weightlessness. Inverse and Flicks both include it in their accounts of screen depictions of sex in space (Inverse; Flicks).
Barbarella (1968)
The opening sequence of Barbarella is a defining image of playful, stylized space-age sensuality: Jane Fonda’s character undresses while floating. It is more clearly a weightless visual gag and erotic image than a literal sex scene. The film’s other sexual episodes—including those involving the Orgasmatron and Pygar—are separate moments, not part of that opening floating sequence. Inverse and Flicks discuss the film’s distinct contributions to the genre (Inverse; Flicks).

Other memorable zero-g and reverse-gravity scenes
Lifeforce (1985)
In this high-camp, gothic science-fiction entry, an astronaut makes love to a space vampire as the ship’s beam pulls them upward. The rising movement evokes weightlessness, but the scene’s mechanism is a beam’s effect—not an ordinary orbital setting. Inverse describes the sequence in its survey of science-fictional zero-gravity sex.
Moving Violations (1985)
This comedy shifts the premise from a spacecraft to a terrestrial NASA zero-gravity chamber. It is a playful training-chamber scenario, not a depiction of sex during a space mission. Inverse includes it among the screen’s zero-g variations (Inverse).

Supernova uses a zero-gravity chamber for crew sexual encounters, including a stylized spinning moment during sex. Its effects-driven treatment makes it an early-2000s variation on the floating-body set piece rather than a realistic account of spaceflight. Inverse discusses the scene in its genre history.
Cube 2: Hypercube (2002)
This is an adjacent case, not a spaceflight scene: the encounter takes place in a reverse-gravity room and becomes a surreal, spinning-body spectacle. It belongs on a broad list of zero-g imagery, but the setting and mechanism distinguish it from people floating aboard a spacecraft. Inverse covers it alongside more literal examples (Inverse).

What counts as zero-g sex on screen?
These scenes fall into different categories, which is why the phrase “zero-gravity sex” can describe more than one kind of screen image:
- Floating in a spacecraft: The Expanse gives the clearest documented example here, with a visible transition when thrust returns.
- Weightless-looking film spectacle: Moonraker and Barbarella use space-age imagery for very different effects—franchise camp and playful sensuality, respectively.
- Simulated or altered gravity: Moving Violations and Supernova use a chamber; Cube 2: Hypercube uses a reverse-gravity room; Lifeforce uses an upward-pulling beam.
That distinction matters: a character floating, a character in a training chamber, and a character pulled upward by a fictional force may look related onscreen, but they do not depict the same setting or mechanism. For more film examples and genre context, see the accounts from Inverse and Flicks.
