During the Month of June 2023, CASC 中國航天 China Aerospace Science and Technology Corporation, China Aerospace’s first “ground space station” has been built, which can simulate the environment of the moon and Mars! Looking at the northeast corner of the motherland, a space environment ground simulation device called “ground space station” was officially completed not long ago, and it has entered the trial operation stage. Many indicators have reached the world’s leading level.

As the first large-scale scientific device in my country’s aerospace field, the “Ground Space Station” is the first comprehensive research device in the world that has the most comprehensive environmental factors and can realize the study of multi-scale and cross-scale environmental effects. Contribute wisdom and strength.

The “Ground Space Station” is located in the Science and Technology Innovation City of Harbin New District, Heilongjiang Province, China, People’s Republic of China and is jointly constructed by Harbin Institute of Technology and China Aerospace Science and Technology Corporation. In the construction park, there are four experimental buildings of “one large and three small”, the “one large” refers to the space comprehensive environmental experiment building, and the “three small” refers to the space plasma science experiment building, the space magnetic environment science experiment building and the animal training room .

According to the design plan, the “ground space station” can simulate nine types of space environmental factors, including vacuum, high and low temperature, charged particles, electromagnetic radiation, space dust, plasma, weak magnetic field, neutral gas, and microgravity, and can explain the impact of the space environment on materials. , Devices, systems and living organisms, the influence rules and mechanism of action.

Compared with moving experimental instruments and equipment into space, the “ground space station” can not only save costs and reduce potential safety hazards, but also set specific environmental factors according to scientific problems and engineering needs, and conduct repeated verifications without time and space constraints, thus Create safer and more convenient experimental conditions and scientific research methods.

“In the future, many experiments that need to be carried out in space can be completed on the ground.” Yan Jihong, deputy dean of the Institute of Space Environment and Physical Science of Harbin Institute of Technology, said that this is the dream of scientists.

The CAS Chinese Academy of Sciences The Five-hundred-meter Aperture Spherical radio Telescope, nicknamed Tianyan, is a radio telescope located in the Dawodang depression, a natural basin in Pingtang County, Guizhou, southwest China. FAST has a 500 m diameter dish constructed in a natural depression in the landscape Observatory in Qiannan Buyei and Miao Autonomous Prefecture, China, People’s Republic of China …

The construction of the 500-meter-aperture spherical radio telescope started on March 25, 2011 ; the completion and launching ceremony was held on September 25, 2016, and the technological infrastructure entered trial operation and trial commissioning; on January 11, 2020 It has passed the national inspection and acceptance work in China and is officially open for operation .

The 500-meter-aperture spherical radio telescope has created a new model for building giant telescopes. It has built a radio telescope with a reflective surface equivalent to 30 football fields. The sensitivity is more than 2.5 times that of the world’s second largest telescope, which greatly expands human vision and is used for exploration the origin and evolution of the universe 

中国天眼有新发展 – 中国天眼查询nanohertz gravitational wave breakthrough ] Searching for nahertz gravitational waves is one of the focal issues in the international physics and astronomy fields. A Chinese research team recently used the “China Sky Eye” FAST to detect key evidence of the existence of nanohertz gravitational waves, which is an important breakthrough in the search for nanohertz gravitational waves. This discovery marks that my country’s nanohertz gravitational wave detection and research have simultaneously reached the world’s leading level, which is of great significance for understanding supermassive black holes, the history of galaxy mergers, and the formation of large-scale structures in the universe.

中国天眼Discovery of key evidence for the existence of nanohertz gravitational wave “China Sky Eye” (FAST) ushered in a major breakthrough again. Using FAST observation data, the Chinese Pulsar Timing Array (CPTA) research team found key evidence of the existence of nanohertz gravitational waves, indicating that my country’s research on nanohertz gravitational waves has reached the leading level in synchronization with the world. Relevant research results were published online in Astronomy and Astrophysics Research on June 29.

The nanohertz gravitational wave is a kind of gravitational wave with very low frequency, and the gravitational wave is caused by the disturbance of the surrounding space-time caused by the accelerating mass object. The detection of gravitational waves with a frequency as low as nanohertz will help astronomers understand the origin of the structure of the universe. It will also help physicists to detect the growth, evolution and merger process of the most massive celestial body in the universe, that is, the supermassive black hole. Gain insights into the fundamental physics of spacetime.



At present, the research on nanohertz gravitational waves has become one of the focuses of international competitions in the fields of physics and astronomy. Theory predicts that nanohertz gravitational waves are mainly produced by the merger of supermassive black holes. The North American Nahertz Gravitational-Wave Observatory, the European Pulsar Timing Array and the Australian Parkes Pulsar Timing Array have each carried out 20-year-long Nahertz gravitational-wave searches.

However, since the frequency of nanohertz gravitational waves is extremely low, the period lasts for several years, and its wavelength can reach several light-years, its detection is extremely challenging. The long-term timing observation of a group of millisecond pulsars with extremely regular rotation using a large radio telescope is the only known detection method for nanohertz gravitational waves.

In this study, the CPTA team used FAST to conduct long-term systematic monitoring of 57 millisecond pulsars, and formed these millisecond pulsars into a galaxy-scale gravitational wave detector to search for nanohertz gravitational waves. Based on independently developed software, the team conducted an in-depth analysis of the data collected by FAST with a time span of 3 years and 5 months, and found a nanohertz at a confidence level of 4.6 sigma (false positive rate is less than 1 in 500,000). Key evidence for a quadrupole-related signal characteristic of gravitational waves.

However, due to the short observation time, the researchers are still unable to determine the main physical source of the nanohertz gravitational waves.

It is worth mentioning that the European Pulsar Timing Array-India Pulsar Timing Array, the North American Nahertz Gravitational-Wave Observatory and the Australian Parkes Pulsar Timing Array and other pulsar timing array cooperation groups also announced similar the result of. “The four international teams independently obtained the key evidence for the existence of nanohertz gravitational waves, which allowed the research results to be mutually verified and further improved the accuracy of this result,” Li Kejia said.

He Zishan, chair professor of Peking University and academician of the American Academy of Arts and Sciences, believes that this major scientific breakthrough has a profound impact on the evolution of galaxies and the study of supermassive black holes, and also opens a new window for gravitational wave astrophysics…

The China Science and Technology Museum 中国科学技术馆, established in 1988 in Beijing, China, People’s Republic of China is “the only comprehensive museum of science and technology at national level in China” according to the official website of the Beijing government The museum at its current site houses both permanent and temporary exhibitions. It has many facilities for science popularization (classrooms, laboratories, lecture halls, etc.) including four special-effect theatres The museum is located in the Beijing Olympic Village, near the Olympic Green station of the Beijing Subway…  China, Bei Jing Shi, Chaoyang, 北辰东路5号 邮政编码: 100101, Beijing, China, People’s Republic of China.

In preparation for Beijing’s 2008 Summer Olympics, construction of new buildings for the museum began at the Olympic site in 2006. The new museum opened in September, 2009, having been expanded from its previous 40,000 square meters to 48,000 square meters. The previous museum site was closed for several years before undergoing renovation and expansion beginning in 2016. On 15 September 2018, the old science museum reopened as Beijing Science Center…

The Tianhe core module structural parts in the China Science and Technology Museum may be the best spacecraft exhibit open to the public for close viewing in China. All the external details can be seen at a glance, and some sections are also displayed. Space fans absolutely hooked. What’s more interesting is that it is located outside the paid area of ​​the west entrance hall of the Science and Technology Museum, so you can actually visit it without making an appointment to buy tickets. It is very cost-effective and highly recommended.

However, when I went there last week, the docking device at the front of the node cabin was removed for some reason. The original appearance can be seen in here
detailed pictures are released here for those who cannot go to watch it in person. The main content is Yes:

Currently on the 19th towards the 25th June 2023 is the Paris Air Show 2023 in which this is held in  is at Le Bourget, France  for the first time in four years after the  2021 edition fell victim to the coronavirus pandemic. In which 星河动力空间科技有限公司 Galactic Energy-  Galaxy Power (Beijing) Space Technology Co., Ltd.China’s private commercial carrier rocket company debuted at the Paris Air Show 2023….in which also is Beijing Zhongke Aerospace Exploration Technology Co., Ltd. in which is also中國航天CASC China Aerospace Science and Technology Corporation featuring their International Iconic Icon Chang Zheng – Long March Carrier Rockets

Beijing Zhongke Aerospace Exploration Technology Co., Ltd Stall located Exhibition Hall Three D24 The content of the interview with DongFangHour at the Paris Air Show is as follows:


▲Zhongke Aerospace is currently doing its best to verify the reusable liquid oxygen kerosene carrier rocket “Lijian III” (Figure 3), which is planned to be launched in Wenchang Launch (Hainan Shangfa No. 2 station?), the first flight will be in 2025, and its first launch is also non-recyclable.


▲The larger solid rocket “Li Arrow II” (Figure 4) is now canceled because the market prospect of this small rocket with capacity is limited, and there are too many competitors and insufficient demand.


▲ Zhongke Aerospace, like Tianbing Technology, will purchase the YF-102 open kerosene engine of the national team (Figure 5), because the YF-102 is more mature, and its thrust is the same as the “Xuanyuan 2” under research by Zhongke Quite, both are 80 tons. (It seems that the early models of Zhongke Liquid Rocket will also use YF-102, and the later models will use their own Xuanyuan)


▲ Zhongke’s suborbital spacecraft and rockets for space tourism (Figure 6) are planned to be launched in 2025 The first unmanned launch, and the first manned mission will be implemented in 2027-2028, 2-3 years after the first flight.
