Given the question: Three astronauts returned to Earth safely on Wednesday after a successful 15-day mission , marking another step forward towards the country's goal of building a manned space station by 2020. Zhang Youxia, commander-in-chief of China's manned space program, said the Shenzhou X mission was a "complete success". The Shenzhou X landed safely in north China's Inner Mongolia Autonomous Region at about 8:07 a.m. on June 26, 2013. All three astronauts were in good physical condition. Nie Haisheng, commander of the Shenzhou X crew and a second-time space traveler, was the first to get out of the bowl-like module , followed by Wang Yaping, the only female astronaut of the mission, and Zhang Xiaoguang. During a brief welcoming ceremony held at the landing area, the astronauts waved happily to a crowd consisting of officers, the search and recovery team, and health personnel. "It feels really good to be back home," said astronaut Nie Haisheng. "We are dreamers, and we have now realized our dream," said Zhang Xiaoguang. "Our space dream knows no limit, and our hard work will never stop," he said. Compared with its previous mission Shenzhou IX last year, the Shenzhou X is no longer experimental but considered an applicable shuttle system for sending astronauts and supplies to orbiting modules. The mission aims to further test technologies designed for docking and supporting astronauts' stay in space, as well as to use new technologies related to the construction of a space station. In its 15-day journey in space, Shenzhou X docked with the orbiting space lab Tiangong-1 twice, once through automatic operation and the other manual .The Tiangong-1 space lab has been in orbit for more than 600 days. It's designed to work for two years. The module is considered the first step in building a permanent space station in the future. And the astronauts spent 12 days in Tiangong-1, where they conducted space medical experiments, technical tests and gave a science lesson to students on Earth on June 19 about basic physics principles....
