Lessons From History: Through the Comet’s tail
About 3 a.m. GMT on 1910 May 19, Halley’s Comet passed directly between the Sun and Earth. This event was invisible from Greenwich, the Sun being below the horizon at the time, but observers on the other side of the world, in Hawaii, trained their telescopes on the Sun for signs of the Comet’s head silhouetted against its brilliant disk. They saw nothing. Had there been a solid nucleus as little as 100 kilometres across, the astronomers would have seen it as a dark dot crossing the Sun.
Those who believed that the Earth’s passage through the Comet’s tail would mark the end of the world must have feared the worst when violent thunderstorms broke out over England that night. From Leigh-on-Sea in Essex, an imaginative witness described the lightning as being as ‘almost the colour of blood’. At the Paris Observatory, Camille Flammarion reported that four observers ‘had certain olfactory experiences, which are described variously as a smell of burning vegetables, or a marsh, or of acetylene’. Imagination must have got the better of them, for the Earth’s atmosphere would have prevented the rarefied gases of the comet from penetrating any closer than about 100 kilometres from the ground.
From Greenwich on the night of the Earth’s passage through the tail, Crommelin noticed strange bands of light in the sky. At first he put them down to clouds but later he wondered whether they were anything to do with the comet. The Engineer-in-Chief of the General Post Office wrote to the Astronomer Royal to inform him that no electrical effects were noted on telephone trunk lines during the Earth’s passage through the tail. With hindsight, it now seems that the Earth did not pass through the centre of the tail, but only through its outskirts.
Perhaps the strangest letter about the encounter to be received at Greenwich came from Sze zuk Chang Chin-liang, who wrote from the Imperial Polytechnic College, Shanghai. He thoughtfully enclosed a photograph of himself to accompany his revolutionary theory: ‘It is obvious the comet has no tail at all and the so-called tail must be the Sun rays which, while passing through the body of the comet, look like a tail’. He then confessed his fear: ‘If the body of the comet is transparent and like the Earth has its two poles fairly flat and thus form a convex lens then everything on the Earth will be burnt provided the sunlight passes through the body of the comet and the focus falls on the surface of the Earth’.

THE SYNCHRONIC BANDS OF COMET NEOWISE
Comet NEOWISE (C/2020 F3) is doing something usually reserved for Great Comets. It has sprouted synchronic bands. Also known as "striae," these bands divide the comet's dust tail into linear regions of greater and lesser density.
Jeff Dai in Ankang, Shanxi Province, China, captured the phenomenon on the evening of July 17th 2020:

Comet NEOWISE meet Satellite ! This is an image i captured at last night during the way back to my home from Shanxi to Sichuan province. It's not easy to witness the clear skies, as it's always rainy and flood in south of China. The magnitude of the comet have already go down, but the tail is still visible, around 5-7 degree. But for the photography side, it's more friendly for us, as its appear at the sunset, and the sky is getting dark when the comet go down. For this photo, it's taken by a 85mm lens. I' am very luck to capture the comet and satellite flash (not meteor) together. Wish you enjoy the view.
"Comet NEOWISE is now in its full glory for northern hemisphere observers". "This image is a stack of thirty 1s exposures at ISO800. It clearly shows the formation of synchronic bands within the dust tail."
Synchronic bands have been seen in comet tails for centuries, yet only recently have astronomers begun to understand what they are. The turning point came in 2007 when European and NASA spacecraft observed the formation of striae in Comet McNaught (C/2006 P1). Apparently, the process starts when a chunk of comet detaches itself from the nucleus. Boulder-sized chunks fragment into smaller and smaller pieces, a cascading process shaped into dusty striations by solar radiation pressure.
The disruptions occured when Comet McNaught crossed the heliospheric current sheet (HCS)--a vast wavy structure in interplanetary space separating regions of opposite magnetic polarity. "It appears the dust may be electrically charged, and gets rearranged as it crosses the HCS boundary,"
Could the same thing happen to Comet NEOWISE? It's possible. Photographers monitoring NEOWISE are encouraged to keep a sharp eye on the striae. Changes may be in the offing.

__________________________
And indeed, the Tianwen-1 lander is carrying part of the bone ashes of late Academician Ten Thousands Satellites (万卫星: Wan Weixing) who has passed away on 20th May 2020, and the chief scientist of China's first Mars exploration program.
With the first human to be buried on Martian soil, in Wutuobang Pingyuan (乌托邦平原: Plain of Paradise), China can now legitimately claim the whole of the Red Planet as its rightful core territory. It only requires to build some permanent structure first, such as a tomb or better, a dedicated mausoleum.
To enforce its sovereignty, military factories would need to be deployed on Mars as soon as during the next biennial launch windows of 2022.
Only this way could China be able to field enough robotic infantry, robotic airforce units and robotic counter-space ASAT-Laser and missile units required to defend Mars against tresspassers masquerading as 'scientific Mars landers' and over 'rovers', of the eternal greedy ethnic European squatters and land grabbers.
There will be no more repeat of past tragedies such as Diaoyutai, Nansha, Zangnan, Tuwa or Haishenwai.
What is at stake is not Mars, a first springboard rich in underground rare earth elements (R.E.E.), but the entire Solar System. The Earth has simply not enough exploitable Rare Earth to support such a full scale extra-terrestrial inter-planetary development. Extraterrestrial robotic units can not be be built without rare earth electronic components.
By using wisely the 100 million tonnes of its strategic REE reserve, China can take the lead in the space race, and easily outgun all the ethnic European powers. In this inter-planetary endeavor, the addition of the North Korean 250 million tonnes REE could be an advantageous booster.
As the old Chinese proverb goes:
He who masters the Rare Earth Elements,
Masters the Solar System.
He who masters the Solar System,
Masters the Earth.
- Ancient Chinese proverb
In that order only and not in any others. And that was the trick.
Notice that the wind is already turning for good for the bicentennial-old ethnic European world order aka Pax Britanmericana, as very bad fenshui has been recorded on camera last night with a close Cometary approach (closest to Earth on 23 July 2020) of C/2020 F3 NEOWISE's rocky tail photographed bisecting the path of the ethnic Europeans' ISS-Zarya space station!

China's deep space monitoring network offers support for Mars probe
Xinhua, July 24, 2020
Ground stations of China's deep space monitoring network are tracking the country's Mars probe, which had been sent into the Earth-Mars transfer orbit, sources with Xi'an Satellite Control Center said on Friday.
Operated by the control center, the network consists of three monitoring stations, two in China and one in Argentina. The stations in Kashgar of northwest China's Xinjiang Uygur Autonomous Region, and in Jiamusi of northeast Heilongjiang Province were put into use in 2012, while the station overseas began operations in 2017.
A Long March-5 rocket carrying the Mars probe, Tianwen-1, lifted off from China's Wenchang Spacecraft Launch Site at 12:41 p.m. (Beijing Time) Thursday.
The Argentina station was the first to track the probe at 1:21 p.m. Thursday. The Jiamusi station and Kashgar station locked the target at 9:37 p.m. Thursday and 1:00 a.m. Friday, respectively.
According to scientists, in the following months, the deep space monitoring network will continue to receive and collect data, providing support for the Mars mission.

Mainland, HK cooperate on space telescope to search for dark matter
Source: Xinhua| 2018-10-18 16:04:03|Editor: Li Xia
BEIJING, Oct. 18 (Xinhua) -- Scientists and space engineers from Chinese mainland and Hong Kong are working together on a space telescope to search for the mysterious dark matter in galaxy clusters about 300 million light years away.
The space telescope, with a detector like the eye of a lobster, has been named HKU No.1, and is expected to be sent into space in 2019.
It is a joint project of the University of Hong Kong (HKU), Nanjing University, Beijing Institute of Space Mechanics and Electricity under the China Academy of Space Technology and two commercial space companies in Beijing.
Inspired by the structure of a lobster eye, U.S. scientists invented the focusing technology in the late 1970s. Its biggest advantage is its wide-angle vision.
Many laboratories around the world have made lobster-eye probes to detect X-rays in space, but none has been sent into orbit.
Su Yun, director of the R&D center at the Beijing Institute of Space Mechanics and Electricity, said the institute started to develop a lobster-eye X-ray focusing detector in 2013, and made breakthroughs in the core technology at the end of 2015. In 2016, HKU and other organizations supported the application of the technology in space astronomy.
Astronomical observations show all the known matters account for only about 5 percent of the universe, while 95 percent of the universe is made up of dark matter and dark energy.
Regarded as the two "dark clouds" over the 21st Century physics, dark matter and dark energy are at the frontier of basic physics and cosmology.
What is dark matter? There are many hypotheses.
China launched the Dark Matter Particle Explorer (DAMPE), nicknamed Wukong or Monkey King, at the end of 2015 to detect the high-energy electrons and gamma rays in space, which might be generated in the process of annihilation or decay of dark matter.
"If we compare the signals that DAMPE is looking for as the 'prime suspect' of dark matter, then our lobster-eye telescope is going to investigate another 'suspect' which is the sterile neutrino," said Su Meng, deputy director of the HKU Laboratory for Space Research.
The satellite will also be used to study the hot gas in rich galaxy clusters, observe comets in the solar system and explore the interaction of the solar wind with the earth's magnetosphere, said Su Meng.
Quentin Parker, associate dean of the HKU faculty of science, said the broad mission scope is highly interdisciplinary. It effectively combines the fields of astronomy, earth science and planetary science. The potential science dividend and impact of this satellite is cutting edge.

TAIYUAN, July 25 (Xinhua) -- China sent a new high-resolution mapping satellite into space on Saturday from the Taiyuan Satellite Launch Center in the northern province of Shanxi.
The Ziyuan III 03 satellite was launched by a Long March-4B rocket at 11:13 a.m. Beijing time, according to the center. It was the 341st flight mission by the Long March rocket series.
Also on board the rocket were two satellites used for dark matter detection and commercial data acquisition respectively. They were developed by the Shanghai ASES Spaceflight Technology Co. Ltd.
All three satellites have entered preset orbits, sources with the Taiyuan center said.
26 Jul 2020
The “Lobster-Eye X-ray Satellite” was successfully launched on July 25 (Saturday) into orbit at the Taiyuan Launch Center with the first signal received, riding the Long March 4B lift rocket. The “Lobster-Eye X-ray Satellite” is co-led by Nanjing University (NJU), the Laboratory for Space Research (LSR) of The University of Hong Kong (HKU), the 508 Institute of the Fifth Academy of China Aerospace Science and Technology Corporation (CASC), and Shanghai ASES Spaceflight Technology Co.Ltd. also under the 805 Institute of the Eighth Academy of CASC. It was successfully developed by five years of joint effort by the above outstanding teams. The satellite is equipped with an internally developed “Lobster-Eye” focused X-ray detector and a small high-precision payload platform. During the satellite’s long-term orbit operation, it will verify the ultra-large X-ray field-of-view within the X-ray energy regime and complete several important space X-ray detection experiments. This especially includes carrying out dark matter signal detection research within the X-ray energy regime under earth orbit environment.
Based on the “Lobster-Eye” focusing light theory, the X-ray imaging technology was first proposed in the 1970s, with advantages of large field-of-view, small size, light weight and easy assembly, etc., making it highly suitable for space payload applications. The “Lobster-Eye X-ray Satellite” will be the world’s first in-orbit space exploration satellite equipped with such Lobster-Eye focused X-ray imaging technology. Its core payload was technically guided by Nanjing University and jointly manufactured by the 508 Institute of CASC and China Building Materials Academy (CBMA).
The satellite launch provides an exciting and new platform to continue these highly effective collaborations for the planned up-coming series of satellites. All the participating research teams and units will endeavour to contribute more efforts in core payload technology breakthrough and enhancing our nation’s independent innovation capabilities in space astronomy, deep space exploration and space remote sensing fields. “I hope this project will lead to important scientific advances that reflect well on our two great universities of HKU and NJU and that will provide additional impetus and incentive for greater and deeper collaborations in the future with the Mainland Space program and emerging space economy,” said Professor Quentin Parker, Director of HKU LSR.
Its successful launch marks an important milestone in the hoped-for the emergence of space science research in the Greater Bay Area and encouraging more scientists in the community to engage in nationwide space science projects. The LSR hopes this iconic scientific endeavour may inspire young minds in the HKSAR and beyond to pursue their space dreams and get involved in Science, Technology, Engineering and Mathematics (STEM).
