Scientist Says NASA Must Study Space Sex
Velcroman1 writes "NASA has always been tight lipped on the subject of sex in space — which makes people all the more curious. How would it work? Has anyone done it before? Can a child be conceived in zero-G? With few animal tests (and virtually no human testing), there's been next to no scientific analysis of the issue. Until now. The Journal of Cosmology has published a special issue detailing the mission to Mars, which touches all the bases. In a chapter titled Sex on Mars, Dr. Rhawn Joseph from the Brain Research Laboratory in California discusses everything from the social conditions that would push astronauts to have sex to the possibility of the first child being born on another planet. Such an infant would be the first real Martian — at least by nationality, the researcher pointed out. 'On Mars, the light's going to be different, the gravity will be different, it's a completely different atmosphere,' he said. 'So if you put an infant on Mars, they would adapt to varying degrees of the new environment. And after several generations, you'd have a new species,' he said."
I guess I wouldn't mind being the progenitor of a new species... also, it would get me out of my mom's basement, and most likely result in meeting girls?
Don't count on it.
I dream of a nation where a man is not judged by his skin color but by an number assigned by a credit rating agency.

If the objective were really to populate another planet wouldn't it make more sense to send a bunch of fertile women and a bunch of semen instead of males? The semen would be a lot lighter(big deal when you are talking space travel), require less resources to keep alive etc. Furthermore you could increase genetic variability by having semen from a bunch of males without increasing the number of people sent. Seems like we really are unnecessary guys :P

Virtually no human testing? Given the kind of person who gets into the astronaut corps, I seriously doubt that. There's probably been no official investigation into this done, but when you coop seven mixed-gender, highly intelligent, very curious, extremely goal-driven, competitive problem-solvers up in a small ship for the lengths of time a shuttle mission runs, I think we can pretty much guarantee there's been plenty of unofficial investigations conducted. And there's been IIRC several mixed-gender ISS crews, so ditto there.
I also suspect they've found the entire exercise to be awkward, exhausting (and not in the good way), inconvenient to arrange around all the monitoring that's done, difficult to keep private in those cramped quarters, and generally an awful lot of work for a lot less reward than you'd expect. But if anybody wants to go to Mars they're going to have to figure out how to deal with sex and how to make it reasonably convenient, because no crew's going to remain completely celibate that long.
From how I see it (and from what I believe to know about the mechanics involved)...
When a woman orgasms, her cervix dips into (depending on the position) pool of seed the man released, sucking it in.
Wait, this is how you think sex works? The man orgasms, sex continues, then some time later, the female orgasms and becomes pregnant?!?
If pregnancy depended on the woman orgasming after the man, the accidental pregnancy rate would be close to zero
Speciation doesn't require selection pressure, it only requires that part of the population reproduces independently for sufficient generations. In the case of humans a generation is typically 20 or 25 years, and 'sufficient generations' depends on the size of the isolated population. Smaller populations drift genetically much faster than large, well-mixed populations. But several thousand generations would be needed as a minimum. So we're looking at somewhere in the region of 40 000 to 50 000 years or more for a new species of human to arise.
Selection pressures cause genetic drift to move in particular directions rather than in random directions. They don't *cause* speciation though they do guide the kinds of change that take place.
Hope that helps.

We're talking about a stress-filled, claustrophobic situation in which there would be no possibility of sex for months at a time, if not years. And space travel too.
