     The majority of astronauts from America have been men. At the start of the space programme there was

strong resistance from some people against having women in space. However, some women were very keen

to become astronauts and in the end they were successful. In 1978, NASA began the first training programme

for women astronauts.

     Judy Resnick and Christa McAuliffe were both astronauts and they were both women, but in many other

ways they were very different. Both of them were on Flight STS-5L-L. Judy Resnick was born in 1949 and

studied engineering at university and went on to obtain a PhD 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 programme of research. She

was, in many ways, a professional astronaut whose whole life was devoted to space travel.

     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 (go with sb. esp. on a journey ) astronauts into space. They hoped

that she would be able to communicate with students from space and encourage every one of them to be

interested in space travel. Christa was a secondary teacher in history and social studies. She was a gifted

teacher and she was selected from over 11,000 applicants to go on flight STS-51-L. She was also a very good

communicator and she immediately established (set up) a very good relationship with the news media (radio,

television and newspapers). It was partly because of this that there was a great deal of interest and excitement

about the flight. 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. It is

partly because of the excitement over McAuliffe's place in the flight that the disaster in 1986 had such an effect

on people.
