Long seventh successful maiden flight media: how far is the distance to the Moon? | |, the long seventh Moon _ news
Legal evening news (text/reporter Wen Rujun) today, a new generation of carrier rocket long March, seventh in Wenchang, Hainan spaceport liftoff. Widely believed that Chinese "moon landing" is a matter of, and long March launch of the seventh, meaning "Moon" one step closer.
So, "sooner or later" how late? How early?
The long seventh rocket flying tonight
CCTV reported, after this evening, Hainan Wenchang launch site weather good, satisfy the launch condition. Completed fueling the rocket, a new nontoxic, pollution-free liquid oxygen and kerosene fuel, and greener. Reporters in the command and control center, launch site system has been ready for pre-launch preparations. Long seventh carrier rocket from a science and technology, ecology, environmental protection, cultural integration in the modern green launch achieved its maiden flight, opened its new journey into space.
CCTV news, June 25, at 8:22, a new generation of carrier rocket long March, seventh in Wenchang, Hainan spaceport blasted will load successfully into orbit.
Long seventh launch, which means, China a step closer to the moon.
Before launching to do what?
Ocean Solutions (ID:guanhaijieju) reporter noted this morning, launching site there was rainy weather accompanied by a short thunderstorm, climate change, consult the Meteorological Department the authority for the launch site increase meteorological, but also increases the density of meteorological observations, may cause severe weather to the launching site in real time weather systems and circulation for scientific comparison and analysis.
Hainan Wenchang space launch site weather engineer Guo Xuewen said: "basically is two hours or so to provide a prediction, data analysis in more detail, more intensive data, data is provided by the more than 10 minutes, now increased to seven minutes to provide a set of data. Now sky pretty much like we had expected the weather, good overall situation, launch Windows meet the minimum meteorological conditions. ”
Hainan Wenchang launch fuel local commanders, Bloomberg said: "this morning, we have started the rocket fuel filling, this work is now continued. This time we introduced a new toxic pollution-free fuel, in this process, we will note the change of pressure, temperature, and ensure a smooth filling. ”
In addition to fueling is different from the the long seventh rocket was used to launch a whole new "vertical Assembly, vertical tests, vertical transport and long-range test launch and control" test launch technology. In the command and control center, site communication elements of the system unit, is to launch the latest use of various system information transmission equipment in the final stages of checking and debugging.
Hainan Wenchang launch communications systems engineer Si Changzhe said: "our communication systems using integrated architecture, and built a broadband information transport, intelligent network management, service security of the communication platform for test launches, data, voice, safe, real-time transmission of images. ”
How strong is the long seventh?
As far as ocean Council (ID:guanhaijieju) reporter, 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.
According to Xinhua, built around the year 2020, China will rely on it to launch manned space station cargo ship.
Long seventh development units--aerospace science and Technology Corporation, China Academy of launch vehicle technology introduction, as China's next space launch mission "the main force in" the long seventh, will meet the long-term needs of manned launch vehicle replacement.
Ocean Solutions (ID:guanhaijieju) reporter learned that according to the official, total length of the long seventh rocket 53.1 m, core-level 3.35 meters in diameter, bundle 4 2.25 m diameter boosters, booster twice times the length of active launch vehicles, a takeoff weight of 597 tons. With independent intellectual property rights, China's liquid-oxygen/kerosene engine, realization of nontoxic, pollution-free.
Due to the temperature of the liquid oxygen to lingxia183sheshidu, in the development of rocket experiment, after each cryogenic fueling, test cell towers on the ground like a "cold storage".
Although appears to be "steel" big man, weighing hundreds of tons, but rocket 90% or more of body weight is fuel. Due to the weight of fuel can not arbitrarily increase or decrease, in order to bring more "passenger" in space, reduce the weight of the rocket is the key. Therefore, the "up to seven" rocket shells are very thin, the thinnest is only 0.8 mm, and egg shells, can be said to be thin as cicada's wings are amazing.
13.5 tons of its capacity for near-Earth orbit, Sun-synchronous orbit of 5.5 tons and medium-launch vehicles, China will increase the carrying capacity of near-Earth orbit from 8.6 tonnes to 13.5 tons to reach international advanced level of similar rockets.
Worth mentioning is that the long seventh overall design team is also very "steal": 80% are more than 35 years of age, 46% has a doctorate.
"Moon landing" what are the problems to be solved?
Ocean Solutions (ID:guanhaijieju) reporter learned that successful manufacture of the long fifth, so that the overall level of China's launch vehicle will really enter age to keep pace and the United States and Russia.
However, the national people's Congress representatives, Deputy designer of the Lunar and lunar phase III Chief Architect Hu Hao said in a media interview, warned that new rocket and launch new rocket of Wenchang in Hainan new launch site, need to be tested in practice, running, once a technology problem, are likely to influence the Chinese lunar landing process.
In addition, different from lunar exploration, Moon is another consideration, the astronauts needed "life support system"-food, oxygen and water recycling. This is Ao Hu, and not too much of a setback, just to more in the future development of test running. After all, after the manned SHENZHOU fifth, China's health care system is mature.
Experts in future to complete the construction of the lunar module, space station and deep space exploration, which rely on existing rockets cannot do. To achieve manned it needs heavy launch vehicle, rocket-related research work currently being carried out.
Around 2017, perform the first lunar sample return Chang fifth, its weight will be Chang third twice. To do this, launch in China by far the most powerful next-generation launch vehicle "the long fifth", one for Chang third tasks, is preparing for the future manned moon landing.
2015 early, China rocket technology Institute Secretary of the Liang Xiaohong in accept interview Shi said, heavy rocket of key technology development also has started, defense technology industrial Council has official approved heavy rocket of key technology in-depth research, main including two a aspects: a is general technology, II is engine technology, to achieved heavy rocket took off thrust in "March fifth," large rocket 1000 tons of based Shang upgrade to 2000-3000 tons of target.
From the "moon landing" how far is it?
Rocket carrying capacity-how much, how big is the stage of China's space, space activities have much greater capacity.
Ao Hu said the aerospace sector has organized a demonstration at present, it is generally believed that Chinese landing on the Moon was a matter of.
According to rocket technology Institute introduced, China currently development scale and technology span maximum of rocket--March fifth, Yu this year second half of flew, has near to track 25 tons, Earth synchronization transfer track 14 tons of carries capacity, and international Shang mainstream rocket of carries capacity quite, will bear launches Chang fifth,, and station core class and Mars detection, has milestone meaning of major task, sharply improve has China into space of capacity.
The Xinhua Agency said within 15 years, China is expected to launch a heavy launch vehicle. In currently of design blueprint in the, heavy rocket arrows body diameter near 10 meters, full arrows total long near hundred meters, carries capacity is existing rocket carries capacity of 5 times times more, over is development of United States next generation rocket of carries capacity, can meet future manned Moon detection, and Mars sampling returns, Sun Department planet detection, variety deep empty detection task needs, guarantees China in future universe exploration and more big more far space of discourse right.

长征七号首飞成功 媒体：距离
登月还有多远？|长征七号|
登月_新闻资讯
法制晚报讯 （文/记者 温如军）今日，我国新一代运载火箭长征七号在海南文昌航天发射场点火升空。业内普遍认为，中国人“登月”是迟早的事，而长征七号的推出，意味着我国离“登月”又近了一步。
那么，“迟早”到底有多迟？有多早？
长征七号火箭今晚飞天
据央视报道，今天傍晚后，海南文昌发射场区气象转好，满足发射条件。火箭完成了燃料加注，全新的无毒、无污染的液氧煤油燃料，更加绿色环保。记者在指控中心看到，发射场各系统已经做好了发射前的各项准备工作。长征七号运载火箭将从这座集科技、生态、环保、人文于一体的现代化绿色航天发射场实现首飞，开启它的全新太空之旅。
据央视最新报道，6月25日8时22分，我国新一代运载火箭长征七号在海南文昌航天发射场点火升空，成功将载荷送入预定轨道。
长征七号运载火箭发射，这也就意味着，中国离月球又近了一步。
发射前做了什么准备？
观海解局（ID：guanhaijieju）记者注意到，今天上午，发射场区出现了阴雨天气并伴有短时雷暴，针对气象变化，发射场气象部门临机增加气象会商，同时也相应加大了气象观测的密度，实时对可能给发射场区造成恶劣天气的气象系统和环流形势进行科学比对和分析。
海南文昌航天发射场气象室高级工程师郭学文说：“基本上是两小时左右要提供一次预报单，数据分析得更加详细，数据更加密集，由原来十几分钟提供一次数据，现在提高到七分钟提供一组数据。现在天象跟我们原来预计的天气差不多，总体情况还良好，发射窗口满足发射的最低气象条件。”
海南文昌航天发射场燃料加注现地指挥员彭博说：“今天上午，我们已经开始了火箭燃料的加注工作，这项工作现在正在持续进行。这次我们采用了全新的无毒无污染的燃料，在这一过程中，我们将注意压力、温度的变化，确保加注工作顺利进行。”
除了加注燃料有所不同外，此次长征七号火箭发射整体上采用了新的“垂直总装、垂直测试、垂直转运和远距离测试发射控制”测试发射技术。在指控中心，发射场通信系统各要素单元，正在对此次发射最新运用的各系统信息传输设备进行最后阶段的检查调试。
海南文昌航天发射场通信系统高级工程师司长哲说：“我们的通信系统采用一体化体系架构，建成了信息传输的宽带化、网络管理智能化、服务安全化的通信平台，为测试发射、数据、语音、图像提供安全可靠、实时的传输。”
长征七号有多强大？
据观海解局（ID：guanhaijieju）记者了解，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它航天器。
据新华社报道，中国2020年前后建成的载人空间站就要靠它来发射货运飞船。
长征七号的研制单位——中国航天科技集团运载火箭技术研究院介绍，作为中国未来航天发射任务的“主力军”，长征七号还将满足载人运载火箭更新换代的长远需求。
观海解局（ID：guanhaijieju）记者根据官方提供的数据得知，长征七号火箭总长53.1米，芯级直径3.35米，捆绑4个直径2.25米的助推器，助推器长度为现役运载火箭的2倍，起飞重量597吨。采用中国具有自主知识产权的液氧/煤油发动机，实现无毒、无污染。
由于液氧的温度达零下183摄氏度，在研制火箭的试验中，每次低温燃料加注后，试验现场的发射塔就像是个“大冷库”。
虽然看起来是“钢筋铁骨”的大个子，体重几百吨，但火箭体重的90%甚至更多都是燃料。由于燃料重量不能随意增减，为了带更多的“乘客”去太空，减轻火箭自重就成了关键。因此，“长七”火箭外壳很薄，最薄处仅有0.8毫米，和鸡蛋壳差不多，可以说是薄如蝉翼却力量惊人。
它的运载能力为近地轨道13.5吨，太阳同步轨道5.5吨，将中国中型运载火箭近地轨道的运载能力由8.6吨提高至13.5吨，达到国外同类火箭先进水平。
值得一提的是，长征七号的总体设计团队也十分“抢镜”：80%以上未满35岁，46%拥有博士学位。
“登月”还需解决哪些问题？
观海解局（ID：guanhaijieju）记者了解到，长征五号的研制成功，让我国运载火箭的整体水平将真正进入和美俄并驾齐驱的时代。
不过，全国人大代表、探月工程副总设计师兼探月工程三期总设计师胡浩曾在接受媒体采访时提醒道，新火箭和发射新火箭的海南文昌新发射场，都需要在实践中进行检验、磨合，一旦哪一个技术环节出现问题，都可能会影响中国人的登月进程。
此外，与月球探测不同，载人登月另一个需要考虑的是，航天员所必需的“生命保障系统”——食物、氧气和水的再生。这一点在胡浩看来，并没有太大的阻碍，只需要在未来的研制试验中进行更多的磨合。毕竟，自神舟五号等载人航天工程之后，我国的生保系统已经比较成熟。
专家介绍，将来我们要完成登月、深空探测、空间站建设，这些依靠现有的火箭都无法完成。要实现载人登月就需要重型运载火箭，我国目前正在进行重型火箭的相关预研工作。
2017年前后，执行首次月球采样返回的嫦娥五号，其重量将是嫦娥三号的两倍之上。为此，我国推出迄今为止推力最大的新一代运载火箭“长征五号”，一来为完成嫦娥三号任务，二来也是为未来载人登月做准备。
2015年年初，中国运载火箭技术研究院党委书记梁小虹在接受采访时表示，重型火箭的关键技术研制也已经启动，国防科技工业局已经正式批准重型火箭的关键技术深入研究，主要包括两个方面：一是总体技术，二是发动机技术，从而实现重型火箭起飞推力在“长征五号”大型火箭1000吨的基础上提升至2000-3000吨的目标。
距离“登月”有多远？
火箭的运载能力有多大，中国航天的舞台就有多大，太空活动能力也就有多大。
胡浩表示，目前航天界已组织了不少论证，大家普遍认为中国人登月是迟早的事。
据运载火箭技术研究院介绍，中国目前研制规模和技术跨度最大的火箭——长征五号于今年下半年首飞，具备近地轨道25吨，地球同步转移轨道14吨的运载能力，与国际上主流运载火箭的运载能力相当，将承担发射嫦娥五号、空间站核心舱以及火星探测等具有里程碑意义的重大任务，大幅提高了中国进入太空的能力。
而新华社的消息称，中国15年内有望发射重型运载火箭。在目前的设计蓝图中，重型运载火箭箭体直径近10米，全箭总长近百米，运载能力是现有火箭运载能力的5倍多，超过正在研制的美国下一代运载火箭的运载能力，可满足未来载人月球探测、火星取样返回，太阳系行星探测等多种深空探测任务需求，保障中国在未来宇宙探索和更大更远空间的话语权。
