No astronaut has officially come forward to admit that they've had sex in space. So Joseph looked to crews working in Antarctica for information and found that men and women do have sex and form romantic relationships on expedition. In fact, seven pregnancies have been recorded down there, despite the great risk to the mother and baby.
The research paper mostly poses a lot of questions: Are women fertile in space? What happens if a baby is born on Mars? Can we prevent sexual conflicts, violence, and competition among astronauts — remember the astronaut who drove miles in diapers to murder her cheating partner's lover? Ultimately, he has a recommendation: male and female astronauts should fly on separate space craft.
