Wen Chang May 14 May 14 at 16 o'clock, people's daily, Ministry of China satellite maritime control looking 21st rocket ship will arrive in qinglan harbor of Wenchang in Hainan long seventh launch vehicle safety. Afterwards, will consist of Wenchang in Hainan spaceport by road transport segment delivered to the rocket launching site, according to plan before the launch of the test preparation. That marked the long seventh launch first mission has entered the implementation stage.
The morning of May 8, the "YuanWang 21st" ship set sail from Tianjin Port, after 6 days and nights at sea, via the Bohai Sea, Yellow Sea, East China Sea, the Taiwan Strait, the South China Sea and other seas, arrived in Hainan Wenchang qinglan port terminal, about 1670-nautical mile voyage. China satellite maritime control Department under the careful organization and implementation, the rocket lifting, transportation and other aspects of safe and smooth, new launch vehicles and rocket ship to withstand complex sea conditions environmental test.
New Hainan Wenchang space launch site in China with more than 2 shoot the rocket launch Tower, in September 2009 to start the construction, in November 2014 was basically completed, and has now successfully completed the long seventh number, practice long fifth launch of its two new launch vehicles, with enabling the long seventh rocket flight task. Flight characteristics, improve the security, reliability, test facilities and equipment from the start of the launch site, thorough technical preparation and job training, and comprehensive maintenance testing, solid staff assessment, at present, the launch site facilities and equipment in good condition, all the preparatory work is proceeding according to plan in an orderly manner.
And Jiuquan, and Taiyuan, and Xichang 3 a space launch site compared, Hainan Wenchang space launch site has latitude low, and launches efficiency high, and shoot wide, and fell district security good, and shipping convenient, advantage, can meet new nontoxic, and no pollution rocket and new spacecraft launches task needs, future will main bear freight spacecraft, and big tonnage station, and Earth synchronization track satellite, and big quality very rail satellite, and deep empty detection satellite, spacecraft launches task.
It is reported that the long seventh carrier rocket is to launch cargo ship of China manned space engineering and 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.
"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 long seventh" flight tasks, the main aim is to verify the correctness 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. After the arrival of rocket launch site, will begin work on assembling and testing, scheduled for launch in late June timing implementation.

　　人民网文昌5月14日电 5月14日16时许，中国卫星海上测控部所属远望21号火箭运输船将长征七号运载火箭安全运抵海南文昌清澜港。随后，将由海南文昌航天发射场通过公路运输方式将火箭分段运送至发射场区，按计划进行发射前各项测试准备工作。这标志着长征七号运载火箭首次飞行任务已进入全面实施阶段。

　　5月8日上午，“远望21号”从天津港装船起航，经过6昼夜海上航行，途经渤海、黄海、东海、台湾海峡、南海等海域，安全抵达海南文昌清澜港码头，总航程约1670海里。在中国卫星海上测控部的精心组织实施下，火箭吊装、运输等各环节安全顺利，新型运载火箭和火箭运输船共同经受住了复杂海况环境考验。

　　我国新建海南文昌航天发射场拥有2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。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，深入开展各项技术准备和岗位训练，全面进行了设备检修检测，扎实进行了各岗位人员考核，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。

　　与酒泉、太原、西昌3个航天发射场相比，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。

　　据悉，长征七号运载火箭是我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。

　　“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。“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。火箭运抵发射场后，将陆续展开有关装配和测试工作，计划于6月下旬择机实施发射。
