The six-woman team have been locked away in a mock spaceship for eight days to see how they interact.
But before they embarked on the test mission, which simulates a flight to the moon and back, the women - who all have backgrounds in medicine or biophysics, and will be expected to perform 30 scientific experiments during the simulation - were asked how they would "cope" without men and cosmetics for eight days.
Yup. Cos obviously that's all they would care about.
The crews of the women's boats in last year's Boat Race repeatedly had to fend off journos asking them about their boyfriends and what their friends thought of their bodies. Cos obviously it's only ok to be strong and fast if you're pretty and don't put off the boys.
