All spacecraft got lifespan limitation and all earth orbiting satellites fall to earth after out of propulsion fuel - 100% follow Newton's law. Regardless country of origin. USA in the past fall the most of space derbies. There is HUGE DIFF because USA just few days ago FAILED launching their Top Secret Giant Spy Satellite ZUMA fell into Indian Ocean, this is very different from those Expired Out of Fuel Satellites, this is FULL OF FUEL Brand New UNUSED. Like crap just fall back to earth on failed launching. With their fuel they are alike random whacking missiles and bombs.


During 911 Boeing 767 full of fuel were hijacked to be used in similar way to Whack Pentagon & WTC. Huat Ah! Kenna Big!

中国刚刚发射的这两颗遥感卫星太厉害,关键时刻可客串侦察卫星!
2018-01-12 19:02 中国
2018年1月9日我国在太原卫星发射中心使用长征二号丁运载火箭采用“一箭双星”的方式将高景一号03/04星发射升空,目前卫星已顺利进入预定轨道。高景一号03/04星将与于2016年12月发射升空的01/02星组成一个0.5米级高精度商业遥感卫星星座,对我国高分辨率遥感卫星的商业化运营探索意义重大。

1d424e73eb8449a49975af96faf8d93c.png


高景一号商业遥感卫星具有超强的探测能力。高景一号由中国航天科技集团公司负责研制,卫星全重560千克,在轨高度530千米,设计寿命8年,分辨率高达0.5米,超过了其前辈高分二号的1.0米级分辨率。高景一号具有超高分辨率、高敏捷度、丰富的光谱波段等技术特点。

高景一号全色分辨率为0.5米,定位精度可保持在20米以内,显现地面细节将轻而易举。同时,高景一号最大侧摆角度可达45度,对于星下快速成像作用巨大,具有点成像、侧摆成像、立体成像、多条带拼接等多种工作模式,单颗卫星每天可采集70万平方公里地域的详细资料,重访周期4天。除此之外,高景一号卫星还具有丰富的光谱波段,具备全色波段和蓝色、绿色、红色和红外波段等4个标准多光谱波段,这将极大地提升成像质量。

740b591d298b45a4b47072ac458072b5.png


高景一号具有重大的商业价值。03/04星完成在轨测试后,高景一号高分辨率遥感卫星星座将初步建成,可为全球用户提供遥感数据服务和应用系统解决方案。同时,高景一号在国土资源调查、测绘、环境监测领域也将发挥巨大作用。除此之外,高景一号还可为保险、金融等行业提供增值服务。综合看来,高景一号商业价值不俗。

40d2d3f8dff6473abd7224d47408fdc8.png


高景一号具有一定的军事潜力,因为将商业遥感卫星用于军事用途的做法早已有之,与军事侦察卫星相比商业遥感卫星具有轨道高、覆盖面广、高精度等特点,因此军事应用潜力不可小觑。以美国的快鸟卫星为例,该卫星可提供亚米级分辨率服务而且重访周期极短,1~3.5天即可完成一次重访,侦察效率高出高景一号不少,美国曾多次将快鸟卫星用于侦察恐怖组织活动和他国军事机密。随着高景一号的出现,中国在军事侦察领域的能力将得到有效提高。

dca9c61914c847b6acc20d66e225367b.png


作为我国航天2018年的首次发射,高景一号高分辨率遥感卫星的成功发射可谓是开门红,高景一号卫星星座的不断完善对中国遥感卫星的商业化应用探索促进巨大,而高景一号在关键时刻也可客串侦察卫星进行军事侦察,这对于完善中国卫星侦察体系至关重要。

中国打破技术壁垒研发巨型光学反射镜 可监控美航母

QOQa-fyqrewi3629945.jpg

  1月8日,2017年度国家科学技术奖励大会在人民大会堂举行,我国四川成都光电所牵头完成的项目获国家技术发明奖一等奖(专用项目),这是光电所连续两年折桂该奖项,而拿下国家发明大奖的项目名称有点让人看不懂——“用于对地遥感卫星的先进空间微结构亚波长薄膜相机技术”,这里面什么是微结构亚波长薄膜相机?一层薄薄的薄膜可以做相机镜头?而且是在太空中造出一个侦察卫星来?怎么做到的呢。军事专家陈忠告诉记者,为了满足高轨道卫星高分辨率对地观测的要求,特别是新一代高性能侦察卫星的需要,美国、俄罗斯、法国和日本等国从上世纪末就开始研究新型光学成像技术,包括大口径单体反射镜成像技术、空间分块可展开反射成像技术、衍射成像技术、基于卫星编队的光学干涉合成孔径成像技术和稀疏孔径成像技术等,目前,前三类技术逐步走向工程化实施阶段,后两类技术由于技术难度过大,发展较为缓慢,还停留在实验室研究阶段。

kFYC-fyqrewi3630017.jpg

  图片为我国自行研制的超大尺寸巨型光学反射镜,尺寸达到2.4米级主反射镜。

  希望通过增大成像镜片的尺寸来看的更清楚更远,目前世界常见的侦察卫星的轨道高度在400至900千米左右,其中最强的已美国“锁眼”-12后续卫星经可以实现0.05米级的成像分辨率,但这种卫星的镜头直径2米,整个卫星重达10多吨,其能看到的范围有限,类似于“锁眼”-12和“8X”(美军秘密雷达光学一体侦察卫星)这样的高级大型光学成像侦察卫星虽然可以采用低轨道提供了较高的分辨率,但这也使得常规低轨道光学成像侦察存在卫星重访同一个侦察地区的周期过长、覆盖侦察地域的范围小等缺点。我们以“锁眼”-12的运行周期为91分钟,这实际上等于一颗“锁眼”-12卫星对指定的某个区域侦察过顶时间只有不到2次,除非增加更多卫星,否则地面目标和人员完全可以对卫星侦察实施反侦察和战术规避。

  如果需要建立一个全球监控卫星群,需要几十颗这样的卫星,那样的造价就是个天文数字,只有一种可能性比较高的,办法就是制造一种具备高分辨率的地球同步轨道卫星,正所谓站的高,看的远,地球同步轨道卫星在距离地面36000千米的地方飞行,理论上在地球外轨道上的三颗等边均匀部署的地球同步轨道侦察卫星就可以实现全球同步侦察,但目前,这种侦察卫星的分辨率前仅为50米级,主要的原因是“光学镜片”不够大,成像能力不足,仅仅能在大海上发现航母这类大型目标,对于我国的要求肯定是不够的,虽然我国是世界上唯一拥有地球同步轨道侦察卫星的国家,但发展一种可以直接对美军海上航母编队的一举一动,都能实现实况直播的高级成像侦察卫星就显得十分重要了。

UROR-fyqrewi3630112.jpg

  为了解决这一问题,目前,世界各国主要采用大口径单体反射镜成像技术、空间分块可展开反射成像技术、衍射成像技术来解决看不清楚的问题,不过,对于反射成像系统,其反射镜必须经过镜坯研磨、轻量化、抛光、镀膜等复杂的加工工艺。美、欧等技术发达国家目前仅能制造3至4米级空间应用的单体反射镜,其中目前世界最大尺寸的碳化硅反射镜直径为3.5米,它就是法国为欧洲“赫歇尔”红外望远镜制造的主反射镜。但这个不是整体烧结的,而是分块烧制后机械拼接的,其镜片研制成本十分高昂,我国长春光机所在近年来通过攻关解决了大直径成像光学镜片的加工技术难关,已经可以制造4米级的碳化硅主反射镜,并采取一次性整体烧结成型技术,其重量仅为“世界第一镜片”的3分之一,而其分辨率将达到空前的1米级,如果一切顺利,这种新型地球同步轨道侦察卫星将在五年内升空。等等,这个和上面的薄膜没什么关系吧?对对,那个薄膜就更厉害了。

N77C-fyqrewi3630225.jpg

  衍射光学薄膜成像侦察卫星的想象图。

  上世纪90年代以来,美国国防先进研究项目局(DARPA)开始研制一种衍射光学薄膜技术,这层薄膜和我们常见的塑料大棚的材质类似,不过上面有一层层特殊涂层,增加了其强度以及反射成像能力,也就是一种可展开光学薄膜反射镜技术,装备有这种技术的卫星入轨后,就像在太空中撑开一个雨伞,甚至可以展开直径为20米的衍射光学薄膜,卫星凝视视场超过一千万平方千米,分辨率高达2.5米,如果制造成40米的“镜片”,就可以实现对航母上飞机和飞行人员的一举一动实施实况直播,几年前,美军的“莫尔纹”衍射光学薄膜技术项目开始研制5米口径光学薄膜成像系统的地面原理样机。2013年4月,美国劳伦斯-利弗莫尔国家实验室向鲍尔公司交付了6块边长约0.8米、面积约0.4平方米的梯形衍射薄膜。随后,鲍尔公司对6块薄膜进行了拼装,制成了主镜1/8扇区的衍射镜片,并开展了光学系统的测试工作,不过,美国人这次慢了。

4Tmf-fyqrewi3630315.jpg

  2014年,我国成都光电所首次完成了直径400毫米的薄膜望远镜研制,在国内首次实现了直径400毫米的微结构薄膜望远镜宽波段(0.49μm至0.68μm)成像系统的成功研制。目前,中科院光电技术研究所在科技部地球观测与导航专项——“静止轨道高分辨率轻型成像相机系统技术”支持下,获得了巨大技术突破,领先美国国防先进研究项目局接近5年的研制进度,目前,我国先进薄膜成像光学系统现阶段,正从原理样机研制到工程样机研制过渡,我国计划造2020年前率先完成13米级薄膜成像光学系统研制,2025年之前实现卫星升空。(作者署名:军情视野)

Democracy Dies in Darkness





The Volokh Conspiracy
Remembering the biggest mass murder in the history of the world



By Ilya Somin August 3, 2016
many of them as part of a terror famine that likely took more lives than the Holocaust. But both Hitler and Stalin were outdone by Mao Zedong. From 1958 to 1962, his Great Leap Forward policy led to the deaths of up to 45 million people – easily making it the biggest episode of mass murder ever recorded.

Historian Frank Dikötter, author of the important book Mao’s Great Faminerecently published an article inHistory Today, summarizing what happened:

Mao thought that he could catapult his country past its competitors by herding villagers across the country into giant people’s communes. In pursuit of a utopian paradise, everything was collectivised. People had their work, homes, land, belongings and livelihoods taken from them. In collective canteens, food, distributed by the spoonful according to merit, became a weapon used to force people to follow the party’s every dictate. As incentives to work were removed, coercion and violence were used instead to compel famished farmers to perform labour on poorly planned irrigation projects while fields were neglected.

A catastrophe of gargantuan proportions ensued. Extrapolating from published population statistics, historians have speculated that tens of millions of people died of starvation. But the true dimensions of what happened are only now coming to light thanks to the meticulous reports the party itself compiled during the famine….

What comes out of this massive and detailed dossier is a tale of horror in which Mao emerges as one of the greatest mass murderers in history, responsible for the deaths of at least 45 million people between 1958 and 1962. It is not merely the extent of the catastrophe that dwarfs earlier estimates, but also the manner in which many people died: between two and three million victims were tortured to death or summarily killed, often for the slightest infraction. When a boy stole a handful of grain in a Hunan village, local boss Xiong Dechang forced his father to bury him alive. The father died of grief a few days later. The case of Wang Ziyou was reported to the central leadership: one of his ears was chopped off, his legs were tied with iron wire, a ten kilogram stone was dropped on his back and then he was branded with a sizzling tool – punishment for digging up a potato.

The basic facts of the Great Leap Forward have long been known to scholars. Dikötter’s work is noteworthy for demonstrating that the number of victims may have been even greater than previously thought, and that the mass murder was more clearly intentional on Mao’s part, and included large numbers of victims who were executed or tortured, as opposed to “merely” starved to death. Even the previously standard estimates of 30 million or more, would still make this the greatest mass murder in history.

This reluctance is an obvious result of the fact that the Communist Party still rules China. Although they have repudiated many of Mao’s specific policies, the regime still derives much of its legitimacy from his legacy. I experienced China’s official ambivalence on this subject first-hand,when I gave a talk about the issue while teaching a course as a visiting professor at a Chinese university in 2014.

II. Why it Matters.

For both Chinese and westerners, failure to acknowledge the true nature of the Great Leap Forward carries serious costs. Some survivors of the Great Leap Forward are still alive today. They deserve far greater recognition of the horrible injustice they suffered. They also deserve compensation for their losses, and the infliction of appropriate punishment on the remaining perpetrators.

In addition, our continuing historical blind spot about the crimes of Mao and other communist rulers, leads us to underestimate the horrors of such policies, and makes it more likely that they might be revived in the future. The horrendous history of China, the USSR, and their imitators, should have permanently discredited socialism as completely as fascism was discredited by the Nazis. But it has not – so far – fully done so.

The best conversations on The Washington Post



Just recently, the socialist government of Venezuela imposed forced labor on much of its population. Yet most of the media coverage of this injustice fails to note the connection to socialism, or that the policy has parallels in the history of the Soviet Union, China, Cuba, and other similar regimes. One analysis even claims that the real problem is not so much “socialism qua socialism,” but rather Venezuela’s “particular brand of socialism, which fuses bad economic ideas with a distinctive brand of strongman bullying,” and is prone to authoritarianism and “mismanagement.” The author simply ignores the fact that “strongman bullying” and “mismanagement” are typical of socialist states around the world. The Scandinavian nations – sometimes cited as examples of successful socialism- are not actually socialist at all, because they do not feature government ownership of the means of production, and in many ways have freer markets than most other western nations.

Venezuela’s tragic situation would not surprise anyone familiar with the history of the Great Leap Forward. We would do well to finally give history’s largest episode of mass murder the attention it deserves.

  2014年,我国成都光电所首次完成了直径400毫米的薄膜望远镜研制,在国内首次实现了直径400毫米的微结构薄膜望远镜宽波段(0.49μm至0.68μm)成像系统的成功研制。目前,中科院光电技术研究所在科技部地球观测与导航专项——“静止轨道高分辨率轻型成像相机系统技术”支持下,获得了巨大技术突破,领先美国国防先进研究项目局接近5年的研制进度,目前,我国先进薄膜成像光学系统现阶段,正从原理样机研制到工程样机研制过渡,我国计划造2020年前率先完成13米级薄膜成像光学系统研制,2025年之前实现卫星升空。(作者署名:军情视野)

Atlas 5 team scrubs launch to study troublesome valve

Launch of an Atlas 5 rocket from Cape Canaveral with a U.S. Air Force infrared surveillance satellite was scrubbed Thursday evening after engineers encountered a balky valve associated with the first stage’s liquid oxygen system.

United Launch Alliance, a 50-50 joint venture between Boeing and Lockheed Martin, said the problem was narrowed to a ground system at Cape Canaveral’s Complex 41 launch pad. The countdown was paused to allow members of the Atlas 5 launch team to study a stuck fill-and-drain valve needed to fill the rocket’s first stage with liquid oxygen.

Engineers investigated the problem before calling off Thursday’s launch attempt, which had a 40-minute window to blast off with the U.S. Air Force’s fourth Space Based Infrared System satellite heading for geosynchronous orbit more than 22,000 miles (nearly 36,000 kilometers) over the equator.

ULA said in a statement that the flight “was scrubbed today due to a ground issue associated with the booster liquid oxygen system.”

The company said another launch attempt was possible Friday, with another 40-minute window opening at 7:48 p.m. EST (0048 GMT), assuming the valve problem is resolved in time.

There is a 90 percent chance of favorable weather for Friday night’s launch window, with a slight concern for cumulus clouds that could pass over the launch pad.

The $1.2 billion SBIRS GEO Flight 4 satellite aboard the Atlas 5 rocket will finish the initial deployment of the Air Force’s new-generation missile-warning network. When complete, the constellation that will include a minimum of four SBIRS craft stationed in geosynchronous orbit and at least two infrared payloads in egg-shaped orbits aboard top secret National Reconnaissance Office spy satellites, providing polar coverage.

Built by Lockheed Martin, the SBIRS satellites carry sharp-eyed infrared sensors to detect heat plumes from rocket launches, feeding data to the military about the origin and trajectory of missiles that could be heading for U.S. territories, deployed troops, or allies.

The infrared payloads are provided by Northrop Grumman.

Three previous SBIRS satellites launched on Atlas 5 rockets in 2011, 2013 and 2017. The fourth will give the SBIRS fleet global coverage, replacing missile detection capabilities currently provided by older, previous-generation Defense Support Program satellites.

Four “SBIRS HEO” piggyback sensor packages have launched on classified NRO spy satellites. Two are needed operational at any time.

The Air Force has ordered two more SBIRS satellites for launch in 2021 and 2022 to improve coverage, and eventually replace the first two SBIRS geosynchronous spacecraft.

“The succesful launch and operation of this fourth SBIRS GEO satellite will mark the completion of the SBIRS baseline constellation,” said Col. Dennis Bythewood, director of the remote sensing systems directorate at the Air Force’s Space and Missile Systems Center. “SBIRS is intended to replace the legacy Defense Support Program satellites that have been providing missile warning for worldwide missile launches since 1970.
“The SBIRS constellation delivers timely, reliable and accurate missile warning and surveillance information to the president, the secretary of defense, combatant commanders, the intelligence community and other key decision-makers across our nation,” Bythewood said in a pre-launch briefing with reporters.
The Atlas 5 flight with SBIRS GEO Flight 4 will mark the first of the year for ULA’s workhorse rocket, and the 75th Atlas 5 launch overall since it debuted August 2002.

This video leaked the secret that the Long March type #11 space satellite carrying rocket is same as DF-41 ICBM!

The launch this week included 2 spy satellites (吉林series 1, #7&#8 plus 4 other smaller satellites. 6 satellites in a single rocket same.

Important difference is this is a Solid Fuel Rocket same as ICBM DF-41, many had been mass produced and stock up with long shelf-life and can be used to launch satellite or warheads within SHORTEST TIME. Satellite Launch can be ready within 24Hr instead of 1 month in the case of liquid fuel rockets. This means in war time, China can rapidly replenish war stricken satellites or suddenly deploy unexpected new satellites of unexpected orbit, just for the war. Enemy caught by surprises. These can be spy or navigation or communication or attack satellites (laser & signal & star war satellite killer). These war satellites could had already been produced and in stock, and many can be launched within very short time.
