Which of the following is true about Judy?

Most astronauts from America have been men. However, some women were very keen to become astronauts and in the end they were successful.
    Judy Resnick and Christa McAuliffe were both women astronauts on Flight STS-51-L, but they were very different. Judy was bom in 1949 and studied engineering at university and went on to obtain a Ph D in 1977. She was a member of the first group of women selected for astronaut training in 1978, and in 1984, she became the second woman in space. During that flight, she helped to launch three new satellites and she carried out a program of research. She was a professional astronaut.
    Christa McAuliffe was born in 1948 and she was an astronaut almost by accident. In 1984, NASA decided to find a teacher who could accompany astronauts into space. They hoped that she would be able to communicate with students from space. Christa was a secondary teacher in history and social studies and she was selected from over 11, 000 applicants to go on flight STS-51-L. Thousands of students in schools and universities all around the country were looking forward to communicating with Christa in space. Millions of people were watching her flight with great interest.
