It's more than 40 years since NASA chose its first female astronaut but space exploration as a whole is still a male-dominated work environment.
According to Allison McIntyre, a senior NASA engineer at the Johnson Space Center in Houston, a dozen men have already walked on the moon.
Speaking to BBC Radion 5 Live, she said that her centre director is a woman, her former division chief is a woman, they have female astronauts, but they haven't put a woman on the moon yet.
“I think the first person on Mars should be a woman”, she said.
Female astronauts have been in to space, but far more men have been sent into orbit than women.
McIntyre heads up a division that puts potential astronauts through their paces in preparation for space exploration.
