Did you know that women astronauts are required by NASA to go on the Pill continually before going into space? Not only do they want to make sure there's no chance they'll get pregnant before going up, they also want to eliminate menstruation. The article fails to mention the complication that it can take months for your body to learn when not to menstruate and that you're still going to get breakthrough bleeding.
There's also ALL sorts of concerns about bone density - a 2% loss per month for both men and women, but women after menopause likely do not regain it when they land. And most women astronauts are in their late thirties or early fourties so they are getting close to menopause (~50). And they don't have the opportunity to have kids even worse than women in ground-based research science.
And they invariably pass out when standing back on Earth as compared to only 20% of men doing so.
And so on.
There's just so much we don't know about women in space yet - out of around 450 people who have gone to space, there have only been 50 women.
If you haven't yet read The Mercury 13 by Ackmann, do so.
