You know, Kelly mentioned the perchlorates on the surface, they disrupt hormones. Yeah. Right? And there's a bunch of subtle stuff that we haven't got into. Like, if you go to the ISS... The atmosphere is very high in carbon dioxide, orders of magnitude more than on Earth. We can tolerate it, but astronauts often complain of headaches.

Many other chemicals are going to be at different concentrations than we have on Earth. This is the tip of the iceberg. You may have the idea that space stations are kind of like organized projects for answering questions, and they aren't. They're done for political reasons, and scientists get to throw experiments at them. So we have like a grab bag of experiments on reproduction in space.

Some invertebrates, some vertebrates, a very small number of like rodent studies, nothing even close to human. And what we really need is like a generational study on vertebrate mammals in these environments. And it doesn't exist.

Yeah.

Yeah.

Yeah.

Could I add one thing to that real quick? Yeah. We should have put a pin in earlier, which is most of the people who have ever been to space are middle-aged men, overwhelmingly. So when we say we know X, Y, and Z about bodies in space, we are mostly talking about middle-aged men from the U.S. and Russia.

Certainly we know nothing about babies or teenagers, but even like the data on women is quite limited. Women were not allowed into the US program until 1978. Russia technically flew women earlier twice. To this day, it's something like 10% of all people who've been to space are women.

So, you know, we can say we have this kind of data on bodies, but most of the bodies are bodies like mine, middle-aged men, except their bodies are a little more fit maybe. But so like there's very basic data we're still missing.

You know, the way we like to say this is that there is no plan B. Elon Musk might want to put on a cowboy hat and fly off to Mars and start his Martian city and leave this polluted planet behind to its wars and devastation. And if he thinks that, he is a fool because Mars is so bad, you could not, for $10 trillion, make Earth as bad as Mars.
