The appearance of these postcards means that.....launch season is coming up in China! And apparently they are pushing the throttle back to 100% with up to 5 launches this September (!). As shown above, the maiden flights of "China's Vega" Long March 6 and "China's Minotaur" Long March 11 may happen within the next 2 weeks, under the black veil that the Chinese always cover with. :censored:

Two other launches are coming up within the next 4 days with "black payloads" so please wait for my report when they happen! ;)

China builds "two bombs, one satellite" memorial museum

2015-09-13

The Chinese Academy of Sciences (CAS) has built a museum to commemorate those who made China's first atomic bomb, H-bomb, and satellites in the 1960s and early 1970s, an official said Sunday.

It is the first time some researchers have had their contributions and names revealed publicly, said Cao Xiaoye, vice secretary-general of the CAS.

More than 17,000 researchers participated in the "two bombs, one satellite" project, which helped increase China's scientific and defense capabilities and contributed to growth in China's national strength.

Thanks to their efforts, China has become one of the few countries with independent knowledge of nuclear and space technology, he said.

Located on the Huairou campus of CAS University, the museum is housed at the site of the CAS's former rocket test base, which was founded in 1958.

The base was used to develop ground test operations for high energy liquid propellants and engines for long range rockets.

China's Beidou navigation system will provide a highly accurate positioning service in major cities at the end of this year, according to the authorities on Friday.

Officials in charge of the Beidou development said that the positioning will be accurate to meter-level, even to decimeters, which is in the lead worldwide.

According to the three-phase Beidou development plan, 450 base stations will be set up before 2016 to support the accurate service. Confidential base stations will cover the whole country by the end of 2018 and the global satellite navigation system will be completed by 2020.

"The Beidou system is keeping pace with the U.S. GPS. It is regarded as a marvelous system and a milestone in China's aerospace and navigation system," said Yao Jianquan, academician of the Chinese Academy of Sciences.

"It does a good job in various fields including transportation, agriculture, navigation, fishery, culture and logistics," Yao added.
 
China has seen the primary sectors applied with Beidou system, while the system entered the industrialization phase. The first generation Beidou chip, module and antenna reached international standard, with the state-of-art products equipped with Beidou such as smart phones, iPad, and car GPS going into batch applications.

China opens global contest to name dark matter probe

2015/09/29

dampe-naming-competition-renminribao.png


The public will have a chance to name a Chinese dark matter probe satellite expected to be launched by the end of this year.

The competition to name the Dark Matter Particle Explorer (DAMPE) was announced at the Purple Mountain Observatory (PMO) of the Chinese Academy of Sciences (CAS) in Nanjing Tuesday. Entries from any country will be accepted until October 31 and can be submitted online at http://scitech.people.com.cn/DAMPE.

There will be five grand prize winners, 20 first prize winners, 50 second prize winners, 100 third prize winners and 500 memorial award winners. Grand prize winners will be able to watch the satellite launch in person at the Jiuquan Satellite Launch Center.

DAMPE will be the first in a program consisting of five research satellites, and its development is supported by the space science program of CAS, said Chang Jin, chief scientist of the project and PMO researcher.

Scientists believe dark matter exists based on the law of universal gravitation, but have never directly detected it.

Accounting for over a quarter of the universe's mass-energy balance, it can only be observed indirectly through its interaction with visible matter.

Based on the standard model of cosmology, the total mass-energy of the known universe contains 4.9 percent ordinary matter, 26.8 percent dark matter and 68.3 percent dark energy.

Many scientists, including Nobel prize laureate Yang Zhenning, believe that development of dark matter theory might lead to understanding phenomena that can't be explained with current knowledge, triggering "revolutionary progress" in physics.

DAMPE looks like an expensive and complicated four-layer cake turned upside down. It weighs 1.9 tonnes and its payload is 1.4 tonnes. The DAMPE project costs 100 million U.S. dollars and its lifespan is more than 3 years.

DAMPE will observe the direction, energy and electric charge of high-energy particles in space in search of dark matter.

The probe will orbit the earth to study the origin of cosmic rays and observe high-energy gamma rays. Original data from DAMPE could provide solid evidence for the existence of dark matter particles.

DAMPE will have the widest observation spectrum and highest energy resolution of any dark matter probe in the world.

Developers of DAMPE include PMO of CAS, University of Science and Technology of China, Institute of High Energy Physics of CAS, Institute of Modern Physics of CAS, National Space Science Center of CAS, University of Geneva and University of Perugia.

China is soliciting international participation in its future manned space station in the form of foreign modules that would attach to the three-module core system, visits by foreign crew-transport vehicles for short stays and the involvement of non-Chinese researchers in placing experiments on the complex, the chief designer of China’s manned space program said Oct. 12.

But he declined to commit to an international orbital docking technology that would facilitate international participation in the Chinese facility.

The Chinese orbital station, consisting of a core module and two experiment-carrying modules, can be expanded to a total of six modules if international partners want to invest in their own components, said Zhou Jianping, chief designer of the China Manned Space Program at the China Manned Space Agency.

Addressing the 66th International Astronautical Congress (IAC) here, Zhou said the station will have a nominal crew of three, with a maximum capacity of six, with three-member crews being launched aboard Chinese Long March 2F rockets from the Jiuquan spaceport for missions of up to six months.

China has signed initial space station cooperation agreements with the Russian and European space agencies, and while the European Space Agency has begun training astronauts in Chinese, there is no specific plan yet to send astronauts to the Chinese facility.

The core module of the Chinese station is scheduled for launch in 2018, Zhou said. Crew-carrying Chinese capsules will visit the module before the two experiment modules are added to complete the initial station design.

“All the modules and associated vehicles are under development.”

If the current schedule holds – he gave no indication of any financing or technical roadblocks – the station would be ready for full operations “around 2022,” he said.

One of the interesting features of the Chinese space station is that it will be served from two of China’s four spaceports.

The cargo modules will be launched aboard Chinese CZ-5B rockets from the Hainan spaceport in southern China, at 19 degrees north latitude. Pressurized and unpressurized cargo will be launched aboard Long March 7 rockets, also from Hainan.

But China’s Shenzhou crew-transport vehicle is launched from the Jiuquan launch facility at 41 degrees north latitude, in the Gobi Desert of Inner Mongolia.

The station will operate for 10 years or more, at an altitude of 340-450 kilometers with an orbital inclination of 42-43 degrees relative to the equator.

The international space station managed by the United States, Russia, Europe, Japan and Canada, operates in low Earth orbit of around 400 kilometers in altitude, with an orbital inclination of 51.6 degrees, an accommodation to Russia, whose Baikonur spaceport in Kazakhstan is at 46 degrees north latitude.

Zhou said China plans to launch an astronomy telescope into an orbit near enough to the space station to dock to it for upgrades and servicing. He declined to specify the telescope’s size.

Zhou also declined to say whether China’s station would use a technical standard being developed in Europe and the United States that would facilitate future interoperability of orbital stations through common docking technologies.

The annual IAC conferences are routinely filled with commitments to international collaboration from national space agencies. A common docking standard is one of the few concrete examples of progress in this respect. A Chinese refusal to adopt it – Zhen said his office would need to assure its quality – would send a signal about China’s intentions with international partners.

Chang'E-5 lunar return sample update

Chang'e 5 sample return landing site will be in northeastern Oceanus Procellarum

14 December 2015

The Chinese Chang’e 5 (CE-5) lunar sample return mission is scheduled to launch in 2017 to bring back surface regolith and drill samples from the northeastern Oceanus Procellarum region on the Moon. The Lunar Mineralogical Spectrometer (LMS) on the CE-5 lander is a VIS/IR imaging spectrometer (0.48 μm -3.2 μm) designed to analyze the mineralogical composition of the sample return site. LMS employs acousto-optic tunable filters (AOTFs) and is composed of a VIS/NIR module (0.48 μm -1.450 μm) and an IR module (1.4 μm -3.2 μm). It has spectral resolution in the range of 5-25 nm, with a field of view (FOV) of 3°×3°. An aluminum plate and an Infragold plate are used as calibration targets in the VIS/NIR and IR spectral range, respectively. Before launch, a ground verification test of LMS needs to be conducted in order to: 1) test and verify the performance of LMS through evaluation of the quality of image and spectral data collected with simulated lunar samples in the lab; and 2) calculate calibration parameters for calibration on the Moon through simulation of instrument calibration on the ground. The ground verification test will be conducted both indoors (for NIR to medium wavelength IR) and outdoors (for VIS to short wavelength IR). The indoor test will be conducted under condition of <60% relative moisture content, to reduce the effect of water vapor absorption near 2.7 μm. The spectra of simulated lunar regolith/mineral samples in the 2.5 μm -3.2 μm range will be collected simultaneously by the LMS and a calibrated FT-IR spectrometer (Model 102F). The outdoor test will be conducted with solar incidence angle >75° and relative moisture content <60%. The spectra of simulated lunar regolith samples in the 0.48 μm -2.5 μm range will be collected simultaneously by the LMS and a calibrated VIS/IR spectrometer (ASD FieldSpec 4 Hi-Res). In this paper we report the results of the LMS ground verification test regarding the evaluation of LMS spectral and image data quality, mineral identification and inversion ability, and calibration accuracy and geometric positioning accuracy.

Russia plans supplies of rocket engines to China

October 12, 2015; 9:00

"As for the space sphere, we have first of all two projects"

"Those will be agreements on supplies of Russian rocket engines and on reverse supplies of microelectronics from China, which we need, including for the space apparatuses."

Russia plans supplies of rocket engines to China

Huh. I wonder what engines they're eyeing for sale to China.

Also, do the Chinese have any ox-rich preburning engine designs yet? If not... perhaps they'll be buying a handful of NK-33s or RD-180s to learn from before switching to an indigenous design... That's how I'd do it, if I were them, anyways.

China aims to go deeper into space

2015-10-13

As China’s exploration of the moon progresses, its space experts have begun considering going deeper into the solar system – to Mars, asteroids and Jupiter – and a manned deep-space mission.

At a recent conference on deep-space exploration in Harbin, capital of northeast China’s Heilongjiang Province, Liu Jizhong, director of the lunar exploration program and space engineering center, under the State Administration of Science, Technology and Industry for National Defense, urged Chinese scientists and technologists to have a pioneering spirit.

He pointed out that China still needs to tackle key problems, such as how to go into deep space at higher speeds; generating energy and power; and developing space robots that can work in the complicated space environment.

Far side of the moon

Lin Yilu, a senior engineer of the Shanghai Aerospace Systems Engineering Institute, said developing a lunar relay satellite is necessary for future lunar exploration, sending astronauts to the moon, as well as setting up a lunar base.

“If China expands the range of its lunar exploration, such as exploring the south and north poles and the far side of the moon, it needs a constellation of satellites covering different areas of the moon’s surface,” said Lin.

Manned or unmanned?

China has yet to start a manned deep-space exploration program, and experts hotly debate whether it’s necessary to send humans into deep space, or just let robots do the job.

“Can robots replace humans to explore deep space? My view is that robots are suitable for repetitive, heavy loading, and fixed and known work.

However, such ambitions come with a cost, and the biggest would be for the greatly increased scale of the spacecraft and rockets. It would need a heavy-lift launch vehicle with a capacity of more than 100 tonnes to send four astronauts to the moon, and environmental control and life support systems would be essential too, Guo said.

Asteroid “ants”

In recent years, asteroids have become a focus of international space exploration. Scientists say asteroids hold materials that could unlock the secrets of the birth of the solar system and the origin of life.

Chinese experts are discussing the feasibility to send a landing probe and retrieve samples from an asteroid.

But how could a probe land and move on an asteroid that might have an odd shape, almost zero gravity and complicated environment?

Zhang Wangjun, a senior CAST engineer, said wheeled robots like the U.S. Mars rover Curiosity have played an important role in space exploration. But robots with feet are more suitable for moving on hilly terrain with many obstacles.

“Robots with feet can avoid and cross obstacles more easily. We are researching two-feet, four-feet and six-feet robots. It seems that a six-feet robot has more advantages in mobility and flexibility in the complicated environment,” Zhang said.

However, he said, current research only meets the industrial requirements. It is still a long way to go to adapting a robot to the environment of an asteroid.

Zhang has devised asteroid-probing robots like a pair of “ants” that can work independently or cooperatively.

Kuaizhou-11 and Kuaizhou21

2015-10-31 10:59

After two successful launches in 2013 and 2014, with its first rapid response military launcher Kuaizhou-1, the CASIC group is currently developing a larger and more powerful family of rapid reaction launchers, while preserving the Kuaizhou-1 features like payload integrated with fourth stage, fully-storable, solid fuel, launched from a mobile TEL ... etc.

Kuaizhou-11, with a capacity of 1t @ 700 km SSO, will be launched before the end of 2016. Kuaizhou-21 is currently in development.

The group wants to control the launch costs to less than 10 000 USD per kg in orbit, or 10 million USD for 1t.
