China develops ability to intercept Inter-Continental Ballistic missiles
Fayyaz Hussain
August 8, 2015 8:42 pm
SHANGHAI (Web Desk) – China’s Science and Technology Daily magazine reports that China has now developed the capacity to intercept ICBMs.
It has published a report of China’s advances in laser technology, spearheaded by China’s top laser scientist Cheng Yong’s, which have enabled the interception by Chinese military, China Daily Mail reported.
The report says that Cheng Yong and his team have been making breakthroughs in strategic technology vital to the development of photoelectric equipment such as adjust-free laser, DLC film prepared by laser deposition and coherent combination of mutual injection, etc.
ICBM is a ballistic missile with a minimum range of more than 5,500 kilometers primarily designed for nuclear weapons delivery (delivering one or more nuclear warheads).
Cheng has tackled problems that even US experts find difficult, including making the world’s first adjustment-free solid laser.
In 2000, Cheng found that China’s infrared window, the eye of China’s large weapon for interception, was not hard enough to resist injury or chemically stable enough to resist erosion, and it became “blind” under hypersonic speed.
To remedy this, he spent four years developing DLC film prepared by laser deposition.
The film was used in China’s new ICBM defence missile to increase its speed by 30%. In 2011, the missile successfully passed a test to intercept an ICBM in mid-course.

You got it already in Chinese, but there is no any word on ICBM interception. Only a 6 beams jointed solid state laser that drilled a 3 mm steel block instantly in a distance of 30m.

Beidou satellites begin autonomous operation in space
August 14, 2015
After more than 10 days in space, China's 19th Beidou navigation satellite is working autonomously and has set up a link with another satellite.
The two satellites were launched on the same day by a Long March III-B rocket from the Xichang Satellite Launch Center in Sichuan Province, southwest China, on July 25.
Xie Jun, chief designer of the Beidou navigation satellite system, says China has successfully tested the autonomous control technology of the Beidou global navigation satellite constellation, an alternative to U.S.-operated GPS, marking a solid step toward building a system with global coverage.
China plans to set up a complete constellation of 35 satellites, achieving global coverage by 2020.
The "twin sats" surpass their predecessors in speed, accuracy and weight.
"The biggest difficulty is the autonomous navigation technology," Xie said. "We need it to maintain the sustainable development of the project."
Wang Ping, another chief engineer on the project, says the inter-satellite link realizes communication and distance measurement among satellites, bringing autonomous control of the navigation system a step closer.
Autonomous navigation is the project's key to global operation. It enables satellites to work independently, providing users with more accurate data.
Using the Chinese word for the plough, or the Big Dipper, constellation, the project was formally launched in 1994, some 20 years after the inception of GPS. The first Beidou satellite was launched in 2000.
By 2012, a regional network had taken shape and was providing positioning, navigation, timing and short message services in China and other Asian countries.
Beidou is one of the world's four main navigation systems, along with GPS there is Russia's GLONASS, and the European Union's Galileo. All four use autonomous navigation technology.

Guang Xi Nannan Aluminum Co., Ltd.'s project of making super-size aluminum alloy forging block for super heavy lift rocket passed acceptance test.
The 1.32m forging block(hard aluminum alloy cylindrical ingot) has to be made first.
And then it was processed to make the 8.7m diameter alloy ring used for the super heavy lift rocket fuel tank,

Aluminum alloy ring of diameter 8.7 meters
世界最大硬铝合金圆锭首现邕城 ——破解航天“密码” 填补国内空白
你能想象直径超过8.5米、高度超过100米的巨型火箭是怎样一个庞然大物吗？你知道其中最关键的部件是由一个直径1.32米的超大规格硬铝合金铸锭加工而形成的直径超过8.5米的金属环吗？它就像是“金箍棒”变成的“乾坤圈”。
经过一年多的努力，广西南南铝加工有限公司（以下简称南南铝加工公司）首先实现了世界上直径最大的硬铝合金铸锭和直径超过8.5米的超大规格铝合金整体环的制造，填补了国内空白。
这个“高大上”的“乾坤圈”是如何制造出来的？记者走进南南铝加工公司一探究竟。
铝合金上天要“经得起考验”
说起火箭，不少航天迷都知道，我国航天事业已经取得了世人瞩目的成就——从1970年4月24日长征一号火箭成功发射东方红一号卫星至今，长征系列运载火箭已完成200次发射，发射成功率居世界前列。
一般来说，火箭主要是由发动机、燃料贮箱、整流罩等部分组成，其结构材料大部分选用铝合金。铝合金在我们日常生活中的应用比比皆是，但用作航天材料，它的安全性和可靠性有保障吗？
经过合金化后，铝合金的强度和综合性能大大提高。铝合金密度小，比强度和比刚度高，尤其适合航天轻量化要求。火箭在整个发射过程中，整体结构要经受高 温、低温、大过载、冲击等恶劣条件的考验。目前国际上注册的铝合金有近600个牌号，每一类铝合金都有相应的特性，其中2219铝合金具备的高温和低温性 能，以及优异的焊接性能，特别适合运用于运载火箭燃料贮箱和整体结构。
“金箍棒”变身为航天“乾坤圈”
在南南铝加工公司的厂区里，记者看到现场展示着一个显眼的“大圆环”——直径相当于三层楼高度的金属环，这就是用于重型火箭结构最关键部件的大规格铝合金整体环。它是如何制造出来的？又有哪些具体用途呢？
锻造的铝合金整体环直径超过8.5米，首先必须先制作出一个直径超过1.3米的超大规格硬铝合金铸锭。如此大规格的铝合金铸锭铸造成形已经相当困难，还要保证整体组织性能的均匀，确实困难重重。

航天科技五院502所“在轨卫星维护服务”地面试验
2015/08/20
太空机器人加油过程：“左手”抓取、连接 “右手”加油
Space robotic arms refueling: "left hand" gripping follow by "right hand" refueling.

太空机器人加油过程：“左手”抓取、连接 “右手”加油
Space robotic arms refueling: "left hand" gripping follow by "right hand" refueling.
据中国航天科技集团五院502所研发人员介绍，“太空医生”的两个机械臂相当于人的两只手，通过“左手”完成对卫星的抓取和连接，再通过“右手”顶上的加油枪完成对卫星的加油工作。说来轻松，可在太空失重环境下，整个过程就变得复杂了许多。
太空加油难度超过航天器对接 机器人每次运动轨迹都不一样
据研发人员介绍，在空中加油和在地面给汽车加油不一样，首先要对得准。这种对接方式是一种合作姿态的对接。像目标飞行器，比如天宫，是有姿态控制的，但如果是对一颗失效的、没有燃料的卫星，它是不能提供合作的姿态，所以这种对接要比天宫和神舟的对接更难。
据了解，完成每一次任务，每一次操作，机器人的动作轨迹都是不一样的。包括它自己识别对象，识别加注接口，然后自主地控制接壁，规划接臂的轨迹，使得接臂自主到达目标稳定，再切换能力控制，形成稳定可靠的连接，为最后的加油做好准备。
妙手回春：能让卫星“起死回生” 多功能好比瑞士军刀
虽然过程艰难，但这样的燃料补加对很多航天器有着重要意义。许多卫星本身情况良好，仅仅因为燃料耗尽就不得不废弃。如果有了这样的空中加油机器人，就能让燃料耗尽的卫星“起死回生”，而事实上，给卫星加油还只是这位太空航天员众多的技能之一。
除此以外，它还能够自主更换工具，就像瑞士军刀一样。比如拧螺丝时，就能换成螺丝刀；剪切时，就换成剪刀，可以实现多功能的效用。
China Aerospace Science and Technology Corporation Fifth Academy 502 Institutes completed "Maintenance service for in orbit satellites" ground simulation test
In a national astronaut training base in Beijing, a robot with two mechanic arms and various cameras performed a simulated satellite refueling process.
"The two mechanic arms like human hands can connect with a satellite through a gripper on its left hand and refuel the satellite through a fuel nozzle installed on its right hand," said Zhu Zhibin, a robot specialist and developer at China Aerospace Science and Technology Corporation.
Zhu said that the robotic refueling can effectively revive satellites which have gone silent due to fuel exhaustion. But the process is much more complicated in the weightlessness in the outer space.
"First of all, it has to be highly accurate. Current docking of spacecraft is connection of cooperative operation as the targeted spacecraft, such as the orbiting space lab Tiangong, is controllable. But the status control is not available for a silent satellite without fuel. So this kind of docking is more difficult than the one between Tiangong and spacecraft Shenzhou," said Zhu.
According to Zhu, the robot is also designed for other tasks besides refueling satellites.
"It can automatically change tools, like a Swiss Army knife. For example, a screwdriver is available when it needs to turn screws and a scissor is available when the robot needs to cut something. It is multi-functional due to the automatic tool changing," Zhu said.

they should use it to try to fix the fail chinese nigerian satellite that could not open its solar panels. the satellite is still new. it would make very good practice dummy for this robo satellite. if it doesn't work, we'll just turn it into satellite killer and smash everything with them claws

English.news.cn | 2015-08-27 14:33:14 | Editor: Song Miou
TAIYUAN, Aug. 27 (Xinhua) -- China's Yaogan-27 remote sensing satellite was sent into space on Thursday at 10:31 a.m. Beijing Time, from Taiyuan launch site in Shanxi Province, north China.
The satellite will mainly be used for experiments, land surveys, crop yield estimates and disaster prevention.
Yaogan-27 was carried by a Long March-4C rocket, the 207th mission for the Long March rocket family.
China launched the first "Yaogan" series satellite, Yaogan-1, in 2006.
