昨天晚上8点40分左右,华北上空出现了奇妙的景象:一个飞行器拖着长长的尾迹飞行。大家纷纷拍下照片和视频发到社交媒体上。从照片上可以看出,这个飞行器进行了至少一次变轨飞行。当大家纷纷猜测这是什么飞行器的时候,一则没有来源的消息指出这是太原发射的北斗卫星,并进行了机动变轨所以划出了一道漂亮的曲线。

让我们来仔细看看这个曲线是怎么回事:

8646f23c3ff158f_w492_h616.jpg


这个轨迹比较清楚,可以看到从助推段上升到一定高度后,飞行器进行了相当大角度的转弯,这是卫星发射能有的轨迹?

037cfed4c16ac47_w474_h345.jpg


一般而言,卫星变轨都采用霍夫曼变轨技术,顺序是先将卫星发射到绿色的近地圆轨道上,再从这个轨道的某一地点开始进行一次加速进入黄色的椭圆轨道,然后再椭圆轨道的远地点再次加速,这样就可以进入更高的圆轨道了。所以这种大角度转弯压根就不是什么卫星变轨的轨迹。当然,除此之外我们还有其他证据:

77cff01b01391e6_w575_h73.png


有网友指出,这个飞行器的飞行方向是自东向西飞行的。那么就更不是卫星发射了。因为地球是从西向东自转的,地球表面的会产生一个自西向东方向的线速度。而发射卫星正好可以利用地球自转产生的线速度加成来节省一定的燃料。如果要向西发射则会导致火箭需要消耗更多的燃料来抵消地球自转产生的线速度。而且,为了尽可能利用地球自转的速度,航天发射场最好建在赤道附近,这里的地球自转的线速度是最快的。

当然,也许有人会说,某些卫星轨道出于独特的需求其轨道运行方向和地球自转方向是反的,所以需要向西发射。那么下面这张图也能说明这发射的不是一颗卫星:

9d7c08ea0ab9bc1_w560_h642.jpg


这是一张从飞机上拍摄的照片。它提供了地面上难以看出来的细节:这个飞行器改变飞行方向之后,方向是向下的,方向指向地面。从来没有什么卫星发射的变轨会把方向指向地球,这是典型的导弹才会有的飞行方向。

所以,这是一颗什么样的飞行器呢?他为什么会产生这样的尾迹被大家发现呢?先看他飞行产生的尾迹。

很明显,这个尾迹是被阳光照射后发生了反射所形成的,就像我们看到的月亮一样。由于中国幅员辽阔,横跨4个时区,在华北东部地区21点左右的时候,新疆地区才刚刚日落。也就是说此时的中国本土的上空依旧能被太阳所照射到。简单画一个示意图的话,就是这个样子的:

a656edf5be12a61_size98_w1078_h327.jpg


导弹升空后进入日照区域被大家发现,然后变了个方向一头扎向地面然后消失了。大家所看到的只是在高空飞过弹道顶点后进行了剧烈的变向机动,然后改为向下飞行留下的尾迹。

结合大家的照片来看,这次导弹实验是在助推段进行了大角度变向。这个现象和我国高超声速导弹“主动段飞行压低弹道、非连续助推直接起滑”的特征相吻合。也就是说在垂直助推时就将弹道压低,不再直冲云霄而是带有一定的方向偏转。然后关闭助推进行大过载机动,让弹头转入水平飞行后再次进行助推滑翔。:coffee:

然而这次的航迹显示还有所不同:在从垂直上升到转入水平飞行的时候喷射的尾迹没有中断,说明没有关闭发动机。这意味着我们的高超音速技术再进一步,省去了关闭助推器再启动的步奏,有利于保持导弹的速度。技术水平远超美国。

大气层内机动变轨可以说是中国科研人员充满智慧的原创,避免了钱学森弹道和桑格尔弹道(美军高超声速飞行器所采用的“打水漂”弹道)那种高抛弹道“砸”入大气层内时剧烈的环境变化给飞行器带来的冲击(所以美军几次试验都失败了)。为中国高超声速武器的实用化奠定了基础。

昨晚的这次奇观或许是我等普通大众首次目睹高超声速武器在大气层内飞行。不知道美军新上任的太平洋司令部看到这番奇景是否又会向国会要钱。也好奇那些一直认为中国高超声速武器只是“传说”的西方媒体和智库会作何感想。或许,他们真的会认为这是卫星发射吧。

来,昨天的照片看个够:

Thanks a lot @cirr and @LKJ86 for the Ifeng News and other links. Based on the info along with those breathtakingly impressive pics and several short clips (plus info upon the recent A2/AD mightier asset, the DF-26 induction — dubbed by Western media as the “Guam Express”), I am able to pact them into a terse, compact eye-opener tipping info in some other language to pass along via other medium to those less informed society in order to open their eyes and update them about the BIG PICTURE of the latest development related to the wayward island and Trump's new policies to exploit that island as a bargaining chip with China. As well as the increased frequency of the muscle show-off voyages of those CVBGs in waters around China. In short, I just wanna tell them, hey look, China has the cure for those behemoth asset diseases, don't just be fooled by the superficial display of muscles in time of peace :p::p: Showing off is one thing, the real use or value is the other game!

TAIYUAN, May 9 (Xinhua) -- China on Wednesday launched Gaofen-5, a hyperspectral imaging satellite, as part of the country's high-resolution Earth observation project.

The Gaofen-5 satellite was launched off the back of a Long March 4C rocket at 2:28 a.m. Beijing Time from the Taiyuan Satellite Launch Center in northern Shanxi Province. It was the 274th flight mission by a Long March carrier rocket.

The satellite can be used for comprehensive environmental monitoring.

The satellite is developed and produced by China Aerospace Science and Technology Corporation and has a designed life of eight years.

According to Tong Xudong, chief designer of the Gaofen series, Gaofen-5 is the first China-developed satellite that can monitor air pollution. It can dynamically reflect the state of air pollution in China through the monitoring of air pollutants, greenhouse gases, and aerosols.

Gaofen-5 is able to obtain spectral information from ultraviolet to long-wave infrared radiation. It is the world's first full-spectrum hyperspectral satellite for comprehensive observation of the atmosphere and land.

Gaofen-5 has the highest spectral resolution among China's remote sensing satellites. It is equipped with six advanced observation payloads, such as shortwave infrared hyperspectral camera and a greenhouse gas detector.

It can investigate material composition through spectral imaging technology.

Wang Qiao, an official from the Ministry of Ecology and Environment, said the satellite can detect inland water, land surface environment and altered minerals, providing reliable data for China's environmental monitoring, resource exploration, and disaster prevention and mitigation.

It will help reduce China's dependence on foreign hyperspectral satellite data.

Since the Gaofen project began in 2010, China's view of the planet has become clearer.

China will also launch Gaofen-6 this year to form a constellation with other Gaofen satellites in orbit.

China's Three Satellite Payloads Kick off Orbiting with China's GF-5 Launching
May 09, 2018

Anhui Institute of Optics and Fine Mechanics (AIOFM), Hefei Institutes of Physical Science and will be orbiting for a very long time to scientifically support China’s atmospheric research and its pollution prevention.

The three payloads, namely the Environment Monitoring Instrument (EMI), the Greenhouse gases Monitoring Instrument (GMI), and the Directional Polarization Camera (DPC), serve not only to take a picture of the earth, but also to obtain the rapid and accurate information of the earth's atmospheric sensitive components as well as to realize the comprehensive detection of air pollution, greenhouse gases, clouds and aerosols.

During their orbital motion with the GF-5, each payload of the three has its own mission.

EMI is the first high-resolution imaging spectrometer used for the detection of atmospheric trace gases, the indicator of environmental pollution.

It is expected to quantitatively monitor air quality changes and the distribution and transportation of global pollution gases, and to analyze the effects of both human and natural emission on atmospheric composition, air quality, and global climate change.

GMI is to build various observation patterns by obtaining periodic hyperspectral data and quantitatively monitoring greenhouse gases in the atmosphere.

DPC aims to detect optical and microphysical parameters of global atmospheric aerosols and clouds and to provide valid research data of global climate change and high-precision atmospheric radiation correction for earth observation, as well as to realize monitoring of atmospheric fine particle pollution.

Due to the wide imaging fields of view, it takes only one day of EMI and DPC's orbital flight to acquire the global data.

The three payloads, with their synchronous operation on the GF-5, will meet the China's demand in some respect connected with environmental protection. In addition, the excellent performance of the three payloads would also propel China's development of atmospheric remote sensing monitoring.

China’s remote sensing satellites discover 10 Roman ruins in Tunisia
By Deyana Goh
May 10, 2018

Tunisia’s Ministry of Culture recently unveiled that Chinese scientists have uncovered 10 ancient Roman archaeological remains in Tunisia using China’s remote sensing satellites and related space-based technologies.

These sites, located in Gafsa, Tataouine and Medenine, include two Roman forts, three giant water basins, an irrigation system, a cemetery and three fortified Roman military roads lined with walls and watchtowers.

These represent the first archaeological sites outside of China that Chinese scientists have discovered using remote sensing, and were made using a combination of remote sensing data, satellite navigation systems, literature analysis and field research.

Said Wang Xingyuan, the RADI leader of the project, “These archeological remains reflect the military defense system of the southern Roman Empire.”

These efforts are part of China’s Belt and Road Initiative, and involved scientists from China, Tunisia, Italy and Pakistan. The Tunisian project began in 2016, when China’s Institute of Remote Sensing and Digital Earth (RADI), which is part of the Chinese Academy of Sciences (CAS), began processing and analyzing remote sensing data. This was followed by archaeological expeditions to the sites for verification, with the discoveries having been confirmed in April 2017.

At a press conference, Tunisia’s Culture Minister Mohamed Zine el Abidine said that Tunisia welcomes multi-disciplinary scientific cooperation and hopes that the work will continue.

This Tuesday is marking China's third Space Day.

To mark the occasion, "Lunar Palace 1," a bioregenerative life support system at Beihang University in Beijing, opened to the public during the weekend.

Our reporter XYee has more.

A main goal of "Lunar Palace 1" is to explore how a space mission could be totally self-sustaining over a long period of time.

"Lunar Palace" includes two separate cabins specially for growing plants.

And a third includes 4 bedrooms, a bathroom, a sitting room, a waste-treatment room and a room for raising insects.

Du Yao, who is taking part in the project, says 8 volunteers need to live in the closed "Lunar Palace 1" with no input for 365 days in three batches.

"Currently, oxygen and water are 100% self-supplied in Lunar Palace 1. 80% of the food is self-supplied. Certian seasonings like salt, oil and sugar are imported from the outside."

Du Yao says the volunteers harvest grain, vegetables and fruit, while an inedible material has been used to raise mealworms as a source of protein.

Human waste, food residue and other byproducts are treated by bio-techniques and used to help with plant cultivation.

Those visiting "Lunar Palace 1" this past weekend were in awe of what the volunteers have been able to accomplish.

"I can't imagine so many plants can be cultivated there."

"It's very difficult to for a closed ecosystem with people there to sustain. It's amazing that Lunar Palace 1 is so sophisticated and volunteers can live there for such a long time."

"The waste treatment process is pretty good. All the nutrition the plants need can be extracted from this process. "

"365 days being cut from the outside world, it's hard to imagine."

The 500-cubic meter module is China's first and the world's third bio-regenerative life support base.

Experts say it plays a significant role in the Chinese Space Program, as it is providing insight into a potential manned outpost on the moon, as well as future manned missions to mars.

Liu Hong is one of the leaders of the "Lunar Palace 1" project.

"Currently, the experiment stays on the earth. It's just a closed system, without considering the different gravity and radioactivity in space. In the following step, we will work on mini Bioregenerative life support system in space stations, the moon probe or maybe Mars probe."

The current experiment started in May of last year.

The first four volunteers lived inside for 60 days, the second four for 200 days.

The original 4 are now inside for 105 days.

They're due to be released from their self-imposed captivity next month.

For CRI, this is XYee.
China's 'Lunar Palace' breaks record after 365+5 days
By Guo Meiping
2018-05-15 15:19 GMT+8

c017c05243294f4d89863414236317f7.jpg

Started on May 10, 2017, the 365-day project lasted five days longer than planned. The delay, which was intentional, was meant to test the volunteers’ psychological states in unexpected situations.

Placed in Beihang University in Beijing, Yuegong-1 has a total area of only 150 square meters, consisting of two plant cabins and the comprehensive cabin. The volunteers successfully grew fruit and vegetables such as strawberries, soybeans and carrots in the laboratory.

Eight volunteers, all students from Beihang University, were divided into two groups. Two men and two women entered for an initial stay on May 10, 2017. After 60 days, they were relieved by another group of four, who stayed 200 days. The second group of students came out on January 26, 2018, and the initial group entered again, and stayed until Tuesday.

After leaving the cabin, the four volunteers were sent directly to the hospital for a health check. “We will be isolated again,” a female volunteer told CCTV. “We will go through different physical examinations, and will be free after a one-week observation period.”

The experiment is designed to test a bioregenerative life support system (BLSS), in which animals, plants and microorganisms co-exist in a sealed environment, simulating a lunar base. It also examines the physical and mental conditions of humans in such an environment. Oxygen, water and food are recycled within the BLSS, creating an Earth-like environment.

The Yuegong-365 project could strengthen China's knowledge and technical know-how, and help the country's scientists understand exactly what will be required for humans to remain on the moon in the medium and long terms.

According to Professor Liu Hong, chief designer of Yuegong-1, the purpose of the project was to test the stability of the BLSS when "astronauts" take turns living in the cabin.

“Eighty percent of the food could circulate inside,” Professor Liu said in the monitoring room near the cabin. “So in the future, if we want to live on the moon, Mars or anywhere that’s not the Earth, the technology can increase our chances to survive.”

“The experiment showcased our technology, which can support the astronauts, or volunteers, staying inside (the cabin) for a long duration,” she added.
