The space mission highlights several new breakthroughs. The spacecraft will perform China＇s first manned space docking mission with the orbiting lTangong-1 space lab module. A female Chinese as- tronaut for the first time will fly to space as part of a three-person crew. The crew members will stay 13 days in space, a new record of space mission duration. Additionally, Chinese astronauts will enter Tiangong-1 to complete a series of experiments. The mission is expected to lay a solid foundation for the construction of a Chinese space station in 2020.展开更多
中国长征二号 F 运载火箭长征2F 火箭从1992年开始研制,1999年11月首飞成功。在历时8年的研制过程中始终将可靠性、安全性放在首位。火箭的可靠性指标为0.97,这使它成为目前国内可靠性指标最高的运载火箭。运载神舟载人飞船的运载火箭...中国长征二号 F 运载火箭长征2F 火箭从1992年开始研制,1999年11月首飞成功。在历时8年的研制过程中始终将可靠性、安全性放在首位。火箭的可靠性指标为0.97,这使它成为目前国内可靠性指标最高的运载火箭。运载神舟载人飞船的运载火箭长征二号 F 运载火箭被命名为“神箭号”火箭全长58.343米,起飞质量480吨,芯级直径3.35求。它可把8吨重的有效载荷送入近地点高度200千米、远地点高度350千米的轨道。展开更多
