Many people have a dream of walking in space some time. But becoming an astronaut is a very challenging job, as qualifying for the space program always was a serious and difficult task. The history of female astronauts clearly suggests that the female space program training was started way back in 1950. Many woman pilots, often the best in their class, were selected and trained to meet all the challenges. It was believed that females were smaller and lighter in weight than men, and hence were recommended the most.
