The rockets expected to carry China's second orbiting space lab Tiangong-2 and the Shenzhou-11 manned spacecraft into space have been delivered to Jiuquan Satellite Launch Center in northwest China.
中国载人航天工程办公室发布的声明称，这两枚火箭是长征二号F系列运载火箭，将在酒泉卫星发射中心开展总装和测试工作。
A statement issued by the China Manned Space Engineering Office said that the center was where the assembly and testing of the two rockets, which belong to the Long March-2F series of carrier rockets, would be carried out.
这些火箭是上周三从北京经铁路运输的。
The rockets were sent from Beijing last Wednesday by rail.
据中国运载火箭技术研究院表示，与它们的前辈相比，这两枚火箭的功能技术得到了改进，以此来提高安全性和可靠性。
Compared with their predecessors, the two rockets feature technical improvements to improve their safety and reliability, according to China Academy of Launch Vehicle Technology.
天宫二号计划于9月中旬实施发射，搭乘2名航天员的神舟十一号将于10月中旬被送入太空，与天宫二号进行对接。
Tiangong-2 is scheduled to launch in mid-September, and Shenzhou-11, which will carry two astronauts to dock with Tiangong-2, will be sent into space in mid-October.
