5 . There’s no doubt that one of the greatest human achievements is the exploration of the space. Ever since astronaut Yuri Gagarin became the first person to be sent into the orbit around the moon in 1961, scientists have been pushing the boundaries further and further. But until now the exploration into the unknown has been dominated (主导) by men.

Of course, in the past, women were also included in the space projects and played an active role on the ground and behind the scenes. For example, they worked as seamstresses (女裁缝师), sewing vital spaceflight components. In fact, many of NASA’s key works would never have been possible without them. Recently Hollywood produced a movie called Hidden Figures to focus on a group of American female mathematicians, especially the black women, who helped NASA send the first American into space. But this was not women’s only contribution. Back in 1963, Soviet astronaut Valentina Tereshkova became the first woman to be sent into space. However, after that, space flight programs were slow to employ women. In the USA. NASA didn’t accept applications from women to become astronauts until 1978.

But attitudes have changed and leading officials at NASA say that the first person to set foot on Mars should be a woman. The space agency aims to have a sex-balanced workforce but can only achieve that if equal numbers of men and women are trained for science and technology jobs. As Allison McIntryre told the BBC, “My director is a woman. We have female astronauts. We haven’t put a woman on the moon yet. And I think that perhaps the first person to step on Mars should be a woman.”
