11. Good afternoon, everyone. I’m so glad to be here to tell you something about outer space and space exploration. Space explor - ation began in 1957 with the launch of the first artificial satellite. Unmanned spaceships have been launched into space since 1959. By 1961, people were orbiting the Earth. Yuri Gagarin from the former Soviet Union become the first human being to travel in space.
