Can Astronauts Have Sex In Space?

Can Astronauts have sex in space?

Astronauts perspire considerably during spaceflight, implying that sexual activity in zero gravity conditions would likely involve high temperatures, humidity, and droplets of sweat. During a joint space mission, Lee and Davis engaged in the noble act of artificially inseminating frog eggs. According to Chiao, NASA astronauts have maintained good conduct while in orbit, despite the introduction of mixed-gender crews in 1983. Experiments on sexual behaviour in space have primarily centred on animals, with no significant focus on human subjects. So, yes astronauts could technically have sex in space. But it might not be very pleasant.

Have any astronauts had sex in space?

The possibility of sexual activity in space remains uncertain, although it's plausible, given that married couples have journeyed into space together. However, there is no recorded evidence of their intimate relationships. Sexual activity in microgravity can be challenging due to various difficulties. Spaceflight disrupts circadian rhythms, which can impact physical, mental, and sexual health. Speculation about sexual encounters among astronauts has been circulating for a while, fueled by rumors of secret space sex experiments by the Russian or U.S. governments. However, retired astronauts' lack of commitment to continual monitoring and care means that vital data on space travel's effects on the human body may be overlooked. There have been reports of romantic entanglements between astronauts, such as the case of William Oefelein and Lisa Nowak, indicating that such occurrences are not limited to space. Despite this, NASA denies any sexual activity among humans in space and avoids discussing the subject. Male testosterone levels decrease in space, leading to a loss of sex drive, and the radiation exposure during a trip to Mars would exceed current astronaut limits. Scientists are also curious about the reproductive implications of space travel.

The only married couple to venture to space together.

NASA does not allow married couples to go to space together. Why doesn t NASA allow married couples?


NASA's official explanation for this regulation is that the presence of a married couple aboard a space mission could potentially become disturbing to the other astronauts.


In January 1991, Mark Lee tied the knot in secrecy with Nancy Jan Smotherman, a fellow astronaut whom he had met while preparing for their flight. The couple made history as the first and, to this day, the only married couple to travel to space together. Unfortunately, they got divorced in 1999.


How would sex in space work?

According to the New York Post, physicist and astronomer John Millis has likened having sex in space to "skydiving." While some argue that allowing sexual activity in space could enhance the well-being of future space travelers and aid in their adaptation to space life, it presents challenges due to Newton's third law.


As life in space may limit access to intimate partners, privacy, and increase tensions between crew members, experts suggest that sexual activity in space may become a reality in the future. However, the low gravity of space may affect blood flow and pressure, which could impact sexual desire. Currently, space station crews engage in leisure activities such as watching movies, reading, and playing games during their free time.


NASA has not promoted sexual activity in space, as it goes against their scientific research purposes.  However, sex in a zero-gravity environment presents challenges as fluids such as sweat, vaginal moisture, and semen would accumulate and float around the cabin.

Despite the lack of research or plans to address human eroticism in space, national and private space organizations are moving ahead with long-term missions to the International Space Station, the Moon, and Mars. However, taboos and conservative views on sexuality may lead some organizations to ignore the realities of intimacy in space.


Additionally, microgravity can cause alterations in biology, making it harder for humans to feel aroused. Currently, most of the available data on astronaut health comes from those who have only experienced brief stays in space, and research on long-term effects is lacking.


How would sex in space work?

French author Pierre Kohler claimed that NASA commissioned a study on sexual positions in outer space, men's testosterone levels have been found to drop during their time in space, according to physicist and astronomer John Millis. During the space shuttle era, most astronauts were only off the planet for about two weeks at a time.


While a fictional paper, available on the internet, describes subjects experimenting with ten different positions, six of which require a rubber band or sleeping bag-like tube to hold the couple together in zero gravity, the issues surrounding sexual activity in space are related to the free-fall, microgravity environment, says Phil Larson, former spokesperson for SpaceX. The first married couple to go into space was Jan Davis and Mark Lee in 1991, but NASA usually prevents married couples from flying together to avoid damaging the team dynamic.


Even if someone manages to have sex in low-gravity conditions, it would be uncomfortable to see fluids floating around the spacecraft. Reports suggest that NASA and other space agencies have long denied the existence of any sexual activity in space. Lisa Nowak, an astronaut, faced attempted murder charges after driving nearly 1,000 miles to confront a rival for the affections of another astronaut, Bill Oefelein. It is impossible for Nowak and Oefelein to have joined the "62-mile high club" as they were never on the same mission


Former and current astronauts typically do not like to discuss sex on the space shuttle, and NASA says it does not know if it ever happened. This is a problem because during sexual activity, heart rates increase rapidly and breathing becomes harder. Space agencies have yet to make scientific breakthroughs that would allow astronauts to travel through space without need, and sex in space presents difficulties due to the effects of microgravity on the human body.
