火箭发射不怕雷雨天了——火箭院总体设计部十室和703所合作，通过大量的机理研究和试验，终于找到了用复合涂层进行防护的解决方案。简单讲，就是在防热层表面喷涂一种特殊涂层，在雷电来时激发形成具有导电性的等离子层，把电流分散到直径几十倍的区域里，电流不那么集中了，破坏力就弱了。在两年多的时间里，经过多物理场仿真、缩比试验，近日，研究取得重大突破，完成了1:1火箭整舱段级试验，达到国内外标准规定的试验水平，在200千安雷电电流的作用下，壳体防热层不被破坏。200千安的试验电流意味着，自然界95%的雷电作用下，火箭都可以正常发射飞行，不再惧怕雷电，可以全天候发射了。总体设计部十室电气系统总体设计师陈曦介绍，这项技术称为强电磁脉冲防护研究，具有两点独到之处。目前，强电磁脉冲防护研究是基于固体火箭进行的，因为固体火箭对发射机动性的要求比液体火箭更高。该项技术已经具备工程应用条件，后续还将开展缩比飞行试验集成验证，今后在液体、固体火箭上都可应用。(航天科技一院)

Rocket launches are not longer afraid of thunderstorms

The Rocket Academy’s General Design Department and 703 Institute cooperated through a lot of mechanism research and experiments, and finally found a solution for lightning protect with composite coatings. To put it simply, a special coating is sprayed on the surface of the heat protection layer, which would be excited to form a conductive plasma layer when lightning strikes, dispersing the current to an area tens of times the normal diameter, therefore the current would not ve so concentrated, and the destructive power would be weaker.

In more than two years, after multi-physical simulations and scale-down tests, the research has recently achieved major breakthroughs. It has completed the 1:1 rocket whole-stage test, reaching the test level specified by domestic and foreign standards, at 200 kA. Under the action of that lightning current, the heat protection layer of the shell is not damaged. The test current of 200 kA means that the rocket can be launched normally under the action of 95% of the lightning in nature, no longer afraid of lightning, and can be launched all-weather.

Chen Xi, the overall designer of the electrical system in the Tenth institute of the Overall Design Department, said that this technology is called strong electromagnetic pulse protection research and has two unique features. At present, research on strong electromagnetic pulse protection is based on solid rockets, because solid rockets have higher requirements for launch site mobility than liquid-fueled rockets. The technology has already met the conditions for engineering application, and in the follow up, scaled flight test will be carried out for integrated verification, and would be used in both liquid and solid rockets.

The Gravity and Atmospheric Science Satellite developed by Tsinghua University

This is China's first satellite dedicated to the measurement of gravity and atmospheric science. Its main goal is to conduct joint detection of low earth-orbit atmospheric density and gravity field. The satellite adopts a novel configuration of pure spherical shape, which can ensure that the atmospheric resistance has nothing to do with the satellite orientation/attitude, thereby greatly improving the accuracy of atmospheric density measurement. In order to ensure sufficient power supply for the satellite, the team designed a spherical solar cell array and overcame the problem of the small curvature spherical surface mounting process. In order to solve the reliability problem of the locking and release of the spherical satellite during launch and flight, the team independently developed an electromagnetic point-type separation mechanism. This separation mechanism has the advantages of micro-impact, no pollution, and reusability on the ground. An important breakthrough in the field of satellite lock-release technology.

China launches global naming campaign for Mars rover

WENCHANG, Hainan, July 24 (Xinhua) -- The China National Space Administration (CNSA) on Friday announced the launch of a global naming campaign for the country's Mars rover.

According to the Lunar Exploration and Space Program Center of the CNSA, the naming activity will be carried out in four stages, including name submission, top 10 proposed names selected by judges, top three names selected by public voting and the final selection.

From now until midnight on Aug. 12, participants can submit their proposed names through the Baidu mobile app, the official submission channel or to the office of the global naming campaign in a paper form.

The CNSA said the campaign is expected to promote the popularization of space knowledge and attract the public's attention to the space industry.

China launched Mars mission Tianwen-1 on Thursday, aiming to complete orbiting, landing and roving in one mission, and taking the first step in its planetary exploration of the solar system.

Tianwen-1 is expected to reach Mars around February 2021. After it enters Mars' orbit, it will spend two to three months surveying potential landing sites using a high-resolution camera to prepare for the landing in May.

After landing, a rover will be released to conduct scientific exploration with an expected lifespan of at least 90 Martian days (about three months on Earth), and the orbiter, with a design life of one Martian year (about 687 days on Earth), will relay communications for the rover while conducting its own scientific detection.

China seeks payload ideas for mission to moon, asteroid

Friday, Aug 7, 2020

China is soliciting ideas for payloads aboard its proposed missions to the moon, an asteroid and a comet, according to the China National Space Administration.

It is asking for primary, middle school and university students across the country to provide ideas for payloads that would fly aboard the Chang'e-7 probe to the moon, and on another spacecraft to the asteroid 2016HO3 and the comet 133P.

The solicitation aims to arouse students' interest in science and inspire them to explore the universe, said the administration.

The space administration, together with six organizations including the Ministry of Education, the Ministry of Science and Technology, and the Chinese Academy of Sciences, issued a notice about the solicitation in late July.

The solicitation remains open until Oct. 31. Students from Hong Kong, Macao and Taiwan are also welcome to offer ideas.

Winners will be awarded with prize money and invited to witness on-site spacecraft launches, according to the notice.

In 2019, administration officials announced the Chang'e-7 mission plan, which will carry out surveys around the South Pole of the moon, including studying terrain and landform, physical composition, as well as the space environment in the region.

The asteroid mission was also unveiled last year. According to previous reports, China will send a probe to fly around the asteroid 2016HO3 and then land on it to collect samples. The probe will then fly back to the proximity of Earth, and release a capsule to return the samples. After that, the probe will continue its journey. With the assistance of the gravity of Earth and Mars, it will finally arrive at the main asteroid belt and orbit comet 133P.

​

What payload could be more important to be carried aboard Chang'e-7 than the other parts 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 Chinese and only second human to be buried on the lunar soil, China could legitimately claim the whole of the Moon 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 the Moon as soon as Chang'e-9, by 2025-2027.

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 the Moon against tresspassers masquerading as 'scientific Lunar 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, Waimenggu, Waimanzhou or Haishenwai.

What is at stake is neither Mars, a first springboard rich in underground rare earth elements (R.E.E.), nor the Moon, a first extraterrestrial security belt to contain the ethnic Europeans' expansionism, and also 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.

China's Tianqin 2 to test key technology for next-generation gravity satellite
By Liu Caiyu Source: Global Times Published: 2020/8/19 18:02:34

BeiDou-3 Navigation Satellite System

The second phase of China's Tianqin project will verify the key technologies for next-generation gravity satellites, which will serve to carry out precise measurements of Earth's gravity, helping humankind tackle climate change and natural disasters, experts said.

One of the core technologies that the "Tianqin 2" satellite has to verify is the "orbit-intersatellite laser interferometry," the key technology of the next generation of gravity satellites in the world, Ye Xianji from the Tianqin Research Center affiliated with Sun Yat-sen University was quoted by the Science and Technology Daily as saying at a conference in Guangzhou recently.

"China is on the same starting line as the US and Germany in this regard, as every country is accelerating in their breakthrough of next-generation gravity satellite technology and in competition for the leading position," said academician Xu Houze from the Chinese Academy of Sciences.

Li Miao, director of the physics department of the Southern University of Science and Technology in Shenzhen, told the Global Times on Wednesday that gravity satellites can measure changes in the Earth's gravitational field with great sensitivity, helping scientists carry out projects such as Earth mapping and studies of geophysics.

Unlike the previous generation of gravity satellites, the next generation will be more precise in terms of Earth measurement, which the country can use to obtain a more solid data base, helping the economy and people's livelihoods, Zhang Baoxin, an expert at China Aviation News, told the Global Times.

"For example, China has been suffering from strong rainfalls, floods and geological disasters this year. If China has its own gravity satellites, it will be able to offer more precise data to carry out the relevant research," Zhang said.

The next-generation gravity satellite experiment will use two satellites at an orbital height of about 400 kilometers, using laser ranging to help in conducting high-precision mapping of the global gravity field, according to the Tianqin Research Center.

Zhong Min from the Innovation Academy for Precision Measurement Science and Technology with CAS said that the gravity satellite is also of great strategic significance for the country in the fields of national defense and security and in addressing common problems faced by mankind such as climate change and disaster prevention.

The program Tianqin, which means "sky harp," was initiated by Sun Yat-sen University in South China's Guangdong Province in 2015. It will consist of three satellites forming an equilateral triangle around the earth.

Tianqin project leader Luo Jun earlier revealed that the "Tianqin 2" satellite is expected to be launched around 2025.

A gravity satellite mission jointly conducted by NASA and the German Research Centre for Geosciences, named the Gravity Recovery and Climate Experiment Follow-on (GRACE-FO) has been helping scientists observe the melting of ice caps in the North and South Poles, the melting of snow and ice in the Himalayas, rising sea levels, and changes in groundwater reserves worldwide.

Zooming in on dark matter

Most matter in the Universe is dark and completely different in nature from the matter that makes up stars, planets and people. Galaxies form and grow when gas cools and condenses at the center of enormous clumps of this dark matter, the so-called dark matter haloes.

An international research team led by Prof. WANG Jie from the National Astronomical Observatories of the Chinese Academy of Sciences (NAOC) used supercomputers in China and Europe to zoom in on a typical region of a virtual universe as if zooming in on an image of the Moon to see a flea on its surface.

The study was published in Nature on Sept. 2.

The biggest dark matter haloes in today's universe contain huge galaxy clusters, collections of hundreds of bright galaxies. The properties of such clusters, which weigh over a quadrillion (a million billion) times as much as our Sun, are well studied.

On the other hand, the masses of the smallest dark matter haloes are unknown. They are hypothesized to be about the mass of the Earth, according to currently popular theories.

Such small haloes would be extremely numerous, containing a substantial fraction of all the dark matter in the universe. However, they would remain dark throughout cosmic history because stars and galaxies grow only in haloes more than a million times as massive as the Sun.

"These small haloes can only be studied by simulating the evolution of the Universe in a large supercomputer," said Prof. WANG.

The research team, based at the National Observatory of the Chinese Academy of Sciences in China, Durham University in the UK, the Max Planck Institute for Astrophysics in Germany, and the Center for Astrophysics in the USA, took five years to develop, test and carry out their cosmic zoom.

It enabled them to study the structure of dark matter haloes of all masses between that of the Earth and that of a big galaxy cluster. In number, the zoom covers a mass range of 10 to the power 30 (that is a one followed by 30 zeroes), which is equivalent to the number of kilograms in the Sun.

By zooming-in on the virtual universe in such microscopic detail, the researchers were able to study the structure of dark matter haloes ranging in mass from that of the Earth to a big galaxy cluster.

"Surprisingly, we find that haloes of all sizes have a very similar internal structure, i.e., they are extremely dense at the center, become increasingly spread out, and have smaller clumps orbiting in their outer regions," said Prof. WANG. "Without a measure scale it was almost impossible to tell an image of a dark matter halo of a massive galaxy from one whose mass is a fraction of the Sun."

Particles of dark matter can collide near the centers of haloes, and may, according to some theories, annihilate in a burst of energetic (gamma) radiation.

Co-author, Prof. Carlos Frenk from Durham University said: "By zooming in on these relatively tiny dark matter haloes, we can calculate the amount of radiation expected to come from different sized haloes."

Most of this radiation would be emitted by dark matter haloes too small to contain stars and future gamma-ray observatories might be able to detect these emissions, making these small objects individually or collectively "visible".

"This would confirm the hypothesized nature of the dark matter, which may not be entirely dark after all," said co-author Simon White from the Max Planck Institute of Astrophysics. "Our research sheds light on these small haloes as we seek to learn more about what dark matter is and the role it plays in the evolution of the universe."

The simulations were carried out in the Cosmology Machine supercomputers in Guangzhou, China, Durham, England of the UK, and Munich, Germany.
