James Dinneen’s review of A City On Mars was interesting. As its authors say, there has been, to our knowledge, no documented human sexual activity in space. However, given our species’ predilections, I would be surprised if, with the person-hours racked up on past and present space stations, not to mention lunar and other orbital sojourns, nobody has experience of sex in space (24 February, p 29).
