How sex in space could work and the challenges in zero gravity

Sex in space, specifically human sexual activity in the weightlessness of outer space, presents difficulties due to Newton's third law. According to the law, if the couple remain attached, their movements will counter each other. Consequently, their actions will not change their velocity unless they are affected by another, unattached, object. Some difficulty could occur due to drifting into other objects. If the couple have a combined velocity relative to other objects, collisions could occur. There have been suggestions that conception and pregnancy in off-Earth environments could be an issue. [1] [2] [3] [4]


As of 2009, with NASA planning long-term missions for lunar settlements with goals to explore and colonize space, the topic has taken a respected place in life sciences. Scientist Stephen Hawking publicly concluded in 2006 that possibly human survival itself will depend on successfully contending with the extreme environments of space. [5] [6] [7]

Physiological issues

Numerous physiological changes have been noted during spaceflight, many of which may affect sex and procreation. Such effects would be a result of factors including gravity changes, radiation, noise, vibration, isolation, disrupted circadian rhythms, stress, or a combination of these factors. [8]

Gravity and microgravity

The primary issue to be considered in off-Earth reproduction is the lack of gravitational acceleration. Life on Earth, and thus the reproductive and ontogenetic processes of all extant species and their ancestors, evolved under the constant influence of the Earth's 1 g gravitational field. It is imperative to study how space environment affects critical phases of mammalian reproduction and development as well as events surrounding fertilization, embryogenesis, pregnancy, birth, postnatal maturation, and parental care. [9] Gravity affects all aspects of vertebrate development, including cell structure and function, organ system development, and even behavior. As gravity regulates mammalian gene expression, there are significant implications for successful procreation in an extraterrestrial environment.

Studies conducted on reproduction of mammals in microgravity include experiments with rats. Although the fetus developed properly once exposed to normal gravity, the rats that were raised in microgravity lacked the ability to right themselves. [10] Another study examined mouse embryo fertilization in microgravity. Although both groups resulted in healthy mice once implanted at normal gravity, the authors noted that the fertilization rate was lower for the embryos fertilized in microgravity than for those in normal gravity. [11] Currently no mice or rats have developed while in microgravity throughout the entire developmental cycle. [12]


The 2suit (alternately 2-Suit or twosuit) is a garment designed to facilitate low-effort sex in the weightless environments such as outer space, or on planets with low gravity. [13] The flight garment, invented by American novelist Vanna Bonta, [2] was one of the subjects of Sex in Space, a 2008 History Channel television documentary about the biological and emotional implications of human migration and reproduction beyond Earth. [13] [14] [15] The 2suit sparked international discussions in news and political debates as a metaphor for human colonization of space. [16] [17]

Planned attempts

In February 2013, Dennis Tito's Inspiration Mars Foundation announced that they were going to send a two-person crew – a man and a woman – on a 501-day, free-return, flyby mission to Mars and back.[ citation needed ] Jane Poynter stressed the importance of the pre-existing stable emotional bond between the members of the couple. She cited her own experience as being a Biosphere 2 crew member together with her husband Taber MacCallum, who is the chief technology officer of Inspiration Mars.

In June 2015, Pornhub announced its plans to make the first pornographic film in space. It launched a crowdfunding campaign to fund the effort, dubbed Sexploration, with the goal of raising $3.4 million in 60 days. The campaign only received pledges for $236,086. If funded, the film would have been slated for a 2016 release, following six months of training for the two performers and six-person crew. [18] [19] [20] [21] Though it claimed to be in talks with multiple private spaceflight carriers, the company declined to name names "for fear that that would risk unnecessary fallout" from the carriers. [18] A article about the campaign mentioned that in 2008, Virgin Galactic received and rejected a $1 million offer from an undisclosed party to shoot a sex film on board SpaceShipTwo. [19]

Adult film actress CoCo Brown had begun certifying for a co-pilot seat in the XCOR Lynx spaceplane, which would have launched in a suborbital flight in 2016 and spent a short amount of time in zero-gravity. [22] However, XCOR declared bankruptcy before ever flying a space tourist. [23]

Short of actual space, the adult entertainment production company Private Media Group has filmed a movie called The Uranus Experiment: Part Two where an actual zero-gravity intercourse scene was accomplished with a reduced-gravity aircraft. The filming process was particularly difficult from a technical and logistical standpoint. Budget constraints allowed for only one 20-second shot, featuring the actors Sylvia Saint and Nick Lang. [24] Berth Milton, Jr, president and CEO of Private Media Group, says "You would not want to be afraid of flying, that's for sure!" [25]

Science fiction writer and futurist Isaac Asimov, in a 1973 article "Sex in a Spaceship", conjectured what sex would be like in the weightless environment of space, anticipating some of the benefits of engaging in sex in an environment of microgravity. [26]

On July 23, 2006, a Sex in Space panel was held at the Space Frontier Foundation's annual conference. Speakers were science journalist-author Laura Woodmansee, who presented her book Sex in Space; [27] Jim Logan, the first graduate of a new aerospace medicine residency program to be hired by NASA's Johnson Space Center in Houston; and Vanna Bonta, an American poet, novelist, and actress who had recently flown in zero gravity and had agreed to an interview for Woodmansee's book. [13] The speakers made presentations that explored "the biological, emotional, and ... physical issues that will confront people moving [off Earth] into the space environment." [28] NBC science journalist Alan Boyle reported on the panel, opening a world discussion of a topic previously considered taboo. [2]

"Sex in Space" was the title of an episode of the History Channel documentary television series The Universe in 2008. The globally distributed show was dubbed into foreign languages, opening worldwide discussion about what had previously been avoided as a taboo subject. Sex in space became a topic of discussion for the long-term survival of the human species, colonization of other planets, inspired songs, and humanized reasons for space exploration.

The idea of sex in space appears frequently in science fiction. Arthur C. Clarke claimed to first address it in his novel Rendezvous with Rama (1973). [35] Among films that include space-sex themes are Moonraker , Moving Violations , Supernova and Cube 2: Hypercube . In the novelization of Alien , Parker tells Brett about an episode of zero-G sex that went wrong. A more recent and perhaps more realistic description of the mechanics of low-gravity intercourse is presented in "Sex in Space: The Video", a short story contained in Susie Bright's The Best American Erotica 2004. The story uses cheating astronauts to describe techniques humans might use to copulate in space without special apparatus. The difficulties microgravity poses for human intimacy were also discussed in an anonymous fictional "NASA Document 12-571-3570" in 1989, where the use of an elastic belt and an inflatable tunnel were proposed as solutions to these problems. A mission patch and other documents were determined to be hoaxes.[ citation needed ]

Colonization of Venus Proposed colonization of the planet Venus

The colonization of Venus has been a subject of many works of science fiction since before the dawn of spaceflight, and is still discussed from both a fictional and a scientific standpoint. However, with the discovery of Venus's extremely hostile surface environment, attention has largely shifted towards the colonization of the Moon and Mars instead, with proposals for Venus focused on colonies floating in the upper-middle atmosphere and on terraforming.

Asteroids located in the asteroid belt have been suggested as a possible site of human colonization. Some of the driving forces behind this effort to colonize asteroids include the survival of humanity, as well as economic incentives associated with asteroid mining. The process of colonizing asteroids does have many obstacles that must be overcome for human habitation, including transportation distance, lack of gravity, temperature, radiation, and psychological issues.

Colonization of Europa Human occupation of Europa

Europa, the fourth-largest moon of Jupiter, is a subject in both science fiction and scientific speculation for future human colonization. Europa's geophysical features, including a possible subglacial water ocean, make it a possibility that human life could be sustained on or beneath the surface.

Gravitational biology is the study of the effects gravity has on living organisms. Throughout the history of the Earth life has evolved to survive changing conditions, such as changes in the climate and habitat. However, one constant factor in evolution since life first began on Earth is the force of gravity. As a consequence, all biological processes are accustomed to the ever-present force of gravity and even small variations in this force can have significant impact on the health and function and the system of organisms.

Space art Visual art genre

"Space art" is the term for a genre of modern artistic expression that strives to show the wonders of the Universe. Like other genres, Space Art has many facets and encompasses realism, impressionism, hardware art, sculpture, abstract imagery, even zoological art. Though artists have been making art with astronomical elements for a long time, the genre of Space Art itself is still in its infancy, having begun only when humanity gained the ability to look off our world and artistically depicted what we see out there. Whatever the stylistic path, the artist is generally attempting to communicate ideas somehow related to space, often including an appreciation of the infinite variety and vastness which surrounds us. In some cases, artists who consider themselves Space Artists use more than illustration and painting to communicate scientific discoveries or works depicting space, some have had the opportunity to work directly with space flight technology and scientists in attempts to expand the arts, humanities, and cultural expression relative to space exploration.

Weightlessness Absence of stress and strain resulting from externally applied mechanical contact-forces

Weightlessness is the complete or near-complete absence of the sensation of weight. This is also termed zero-G, although the more correct term is "zero G-force". It occurs in the absence of any contact forces upon objects including the human body.

Exomedicine is the study and exploration of medical solutions in the zero gravity environment of space to promote benefits to human health on Earth. The purpose is to advance the field, study, and practice of medicine on Earth through research investigations conducted in the microgravity conditions of space which may provide advances in understanding that cannot be achieved on Earth. Although the Soviet Union launched the first space station, Salyut 1 in 1971, the United States designed and launched Skylab with the intent of advancing the field of science both in space and with regards to terrestrial applications. Beginning as a “memorandum of understanding” between NASA and ESA in 1973, the first major microgravity experiments in space were carried out by “Spacelab”. Gravity is a fundamental force on earth that influences all biological systems at a molecular level. When biomedical research is conducted in Space, in so-called microgravity environments, certain earthbound limitations disappear, new and different findings are made, and living organisms behave very differently.
