Long seventh rocket arrived in Hainan, China in late June launch
New in Wenchang, Hainan, May 14 (Zong Zhaodun Wang Ziqian) 14th at 16 o'clock, long seventh rocket arrived in qinglan harbor of Wenchang in Hainan, China. Subparagraph the rocket will be transported to the launch site, according to plan before launching the test preparations, plans satellite launch in late June.
On May 8, the Ministry of China satellite maritime control looking 21st rocket ship set sail from Tianjin Port shipment via the Bohai Sea, Yellow Sea, East China Sea, the Taiwan Strait, the South China Sea and other seas, arrived in Hainan Wenchang, voyage of nearly 1700 nautical miles.
"This voyage is the first new rockets for transport, smooth the process. "YuanWang 21st rocket ship's captain Shi Kai said China satellite maritime control Department under the careful organization and implementation, the rocket lifting, transportation, unloading, safe and smooth each link," could provide a more comfortable and safe products for the rockets "home" ".
Hainan Wenchang space launch site, new China has fired two rocket launch Tower, in September 2009 to start the construction, in November 2014 was basically completed, and has now successfully completed "long seventh", "the long fifth" launch of its two new launch vehicles training, have the conditions to perform long seventh rocket flight tasks.
The reporter learns, flight characteristics, improve the security, reliability, test facilities and equipment from the start of the launch site, worked on the technical preparation and job training, equipment maintenance testing and staff assessment. Current launch site facilities and equipment in good condition, all the preparatory work is proceeding according to plan in an orderly manner.
Aerospace experts said that Hainan Wenchang space launch site with low latitude and emitter efficiency high, shooting wide, area security, shipping and easy advantage, to meet the new generation of nontoxic, pollution-free carrier rockets and launch new spacecraft mission requirements, the future will be mainly responsible for the cargo ships, large-tonnage space stations, Earth-synchronous orbit satellites, massive polar-orbiting satellites, satellite and deep space exploration spacecraft mission.
"The long seventh" affiliated to China Aerospace Science and Technology Corporation, China Academy of launch vehicle technology to catch the total development, March 2011 project started, has now completed the development and ground testing tasks, has launched flight test conditions. The reporter learns, "long seventh" flew missions mainly aim is to verify the validity of the design and the performance indicators, while carrying a payload of the relevant research institutions to development, to undertake experimental study on space science and technology.
"The long seventh" of China's manned space program to launch cargo ships and a new development of new-generation medium-launch vehicles can also be used to launch satellites and other spacecraft. Rocket uses Lox/kerosene engines new technologies such as arrow total 53.1 meters long, 3.35 meters in diameter core level, bundled 4 booster diameter of 2.25 meters, gross weight of about 597 tons, near-Earth orbits carrying capacity of 13.5 tons.

中国长征七号运载火箭运抵海南 6月下旬发射
中新社海南文昌5月14日电 (宗兆盾 王子谦)14日16时许，中国长征七号运载火箭安全抵达海南文昌清澜港。该火箭将被分段运至发射场区，按计划进行发射前各项测试准备工作，计划在6月下旬择机发射。
5月8日，中国卫星海上测控部所属远望21号火箭运输船从天津港装船起航，途经渤海、黄海、东海、台湾海峡、南海等海域，安全抵达海南文昌，总航程近1700海里。
“本次航程是第一次运输新型火箭，过程平稳顺利。”远望21号火箭运输船船长史开说，在中国卫星海上测控部的精心组织实施下，火箭吊装、运输、卸载各环节安全顺利，“能为火箭产品提供一个更为舒适安全的"家"”。
中国新建海南文昌航天发射场拥有两座多射向运载火箭发射塔架，2009年9月开工建设，2014年11月基本建成，现已圆满完成“长征七号”、“长征五号”两枚新型运载火箭发射场合练，具备执行长征七号火箭首飞任务条件。
记者获悉，针对首飞任务特点，发射场从提高参试设施设备安全性、可靠性入手，开展了各项技术准备和岗位训练、设备检修检测及各岗位人员考核。目前发射场设施设备状态良好，各项准备工作正按计划有序进行。
航天专家称，海南文昌航天发射场具有纬度低、发射效率高、射向宽、落区安全性好、海运便捷等优势，能够满足新一代无毒、无污染运载火箭和新型航天器发射任务需求，未来将主要承担货运飞船、大吨位空间站、地球同步轨道卫星、大质量极轨卫星、深空探测卫星等航天器发射任务。
“长征七号”由中国航天科技集团公司所属中国运载火箭技术研究院抓总研制，2011年3月立项启动，现已全面完成各项研制和地面试验任务，具备进行发射飞行验证的条件。记者获悉，“长征七号”首飞任务主要目的是全面验证火箭设计的正确性和各项性能指标，同时搭载了相关科研机构研制的有效载荷，用于开展空间科学技术试验研究。
“长征七号”是中国载人航天工程为发射货运飞船而全新研制的新一代中型运载火箭，也可用于发射人造卫星等其他航天器。火箭采用了液氧煤油发动机等新技术，箭体总长53.1米，芯级直径3.35米，捆绑4个直径2.25米的助推器，起飞质量约597吨，近地轨道运载能力13.5吨。
