Why the First Crewed Mission to Mars Should Consist Only of Women.

A new study suggests that the first astronauts to travel to Mars should be all women due to their smaller and lighter bodies, which require fewer resources and have a higher likelihood of coming back healthier. The study found that male astronauts require significantly more oxygen, calories, and water, making all-female crews more efficient for the first Mars landing. The push towards smaller Mars habitat modules also supports the idea of all-female crews.
