In the future, only female crews can be sent into space.

Crew support over the years will be an important factor in planning expeditions. One way to save resources could be to send all-female crews. It turned out that they will need less water, energy and oxygen than their male counterparts. The exact difference between the male and female crew will depend on the height and other parameters of the selected astronauts. But in all situations, an all-female crew consumed fewer resources.
