The "Two Bombs, One Satellite" project, as it progressed throughout the 60s and 70s, gave China confidence in its abilities in science. It also fueled popular imagination that the country would one day venture into space. In September 1992, China officially launched its manned space flight program. The greatest and most technically challenging project in China's space program was underway. On October 15, 2003, after 590 seconds, space welcomed its first Chinese visitor – Yang Liwei. China became the third country in the world to launch a human being into the orbit. Since 1956, several generations of spaceflight engineers have devoted their time, efforts and knowledge to the dream of space.
