- Sex in space is a real possibility with the expected growth in space tourism over the next decade, says Cranfield University-led paper
- Researchers say the expected motivations and behaviours of space tourists will differ from that of professional astronauts
- Green paper published today highlights the biological and commercial risk of human conception in space and urges open discussion of this among the space tourism sector and wider communities
It could be a crucial question posed by the expected growth in space tourism over the next decade – namely what would a human conception in space mean for the sector?
That’s the situation posed by an international group of scientists, clinicians and other interested parties, who have authored a consultative green paper led by David Cullen, Professor of Astrobiology & Space Biotechnology at Cranfield University.
It highlights that the emerging space tourism sector has not openly considered or discussed the risks of sex in space or prepared suitable mitigation approaches. It argues it is unrealistic to assume all future space tourists will abstain from sexual activities – opening the possibility of human conception and the early stages of human reproduction occurring in space.
This appears to pose several risks, those of a biological nature such as embryo developmental risks and those of a commercial nature such as liability, litigation, and reputational damage. The authors recommend that an open discussion is now needed within the space tourism industry to consider the risks.
Open discussion on human conception in space tourism is lacking
Professor Cullen from Cranfield University led the work. He said: “Our starting point was a throwaway comment about sex in space, but when we checked, we were surprised the sector has not openly considered the risks and this led to the study.”
The green paper strongly recommends that all the relevant parties involved in the space tourism sector enter into open discussions concerning the risks and mitigations, and develop and disseminate best practice approaches within the sector.
The findings of the study have been published today (24 April) as a green paper for community consultation.
Human reproduction outside of Earth should be taken seriously
Egbert Edelbroek, the head of SpaceBorn United, a Netherlands-based organisation researching human reproduction in space, helped to coordinate the study. He said: “Given the long-term importance of human reproduction beyond Earth, as humanity is trying to become a multi-planetary species, we need to take seriously the possible first step, whether this is planned, or especially if unplanned.”
Alex Layendecker, director of the Astrosexological Research Institute and a co-author of the green paper, said: “The sociological and cultural aspects are fascinating to consider, given the approaching shift from well-trained professional and private astronauts to true ‘space tourists’. That shift will encapsulate changes in motivations, social interactions, and behavioural norms, the impacts of which we need to take seriously.”
The paper will be debated in a parallel session alongside the upcoming Space Tourism Conference 2023 on 28 April in Los Angeles, USA.
