BEIJING — Three Chinese astronauts have returned to Earth after spending 13 days on a historic space mission that made their country only the third nation ever to dock a manned spacecraft to another craft in orbit. The Shenzhou 9 space capsule landed at about 10 P.M. ET (10 a.m. Friday, Beijing time) in Inner Mongolia, an autonomous region of the People's Republic of China. The astronauts left the Tiangong 1 prototype space lab module a day earlier. Their landing was broadcast live on China's state-run CCTV television network, showing the capsule streaking through the atmosphere like a meteor, deploying its main parachute, then making a final landing before rolling over on its side. The mission, which included successful displays of manual and automatic dockings, represented an important leap forward for China's space program. The nation aims to construct a space station in orbit by the year 2020. “Chinese astronauts have their own home in space now,” mission commander Jing Haipeng said from space during a special call from Chinese president Hu Jintao on Tuesday. “We are proud of our country!” While the orbital linkups are important technological achievements for China, the mission also carried a wider social impact, because it included the country's first female astronaut, 33-year-old Liu Yang. The mission was commanded by veteran Chinese astronaut Jing Haibeng. The third crew member, Liu Wang, served as the Shenzhou 9 docking pilot. The Shenzhou 9 mission, which launched into space on June 16, accomplished China's first manned space dockings. The Shenzhou spacecraft robotically docked to Tiangong 1 on June 18. Then, on June 24, the astronauts backed their capsule away from the orbiting module and came back in for another docking under manual control. — Agencies
