July 19, 1964: The first biological rocket was launched, carrying white mice into space. April 1, 1968: Institute of Space Medico-Engineering was established, initiating the selection and training of astronauts and the manned space flight medical engineering research. April 24, 1970: First artificial Earth satellite -- Dong Fang Hong-1 Satellite -- was launched at Jiuquan Satellite Launch Center as China joins the former Soviet Union, America, France and Japan as the fifth country to launch satellites.
