MANOA, Hawaii (University of Hawaii PR) — The first on-the-ground detection of water on the Moon’s surface was reported by an international team of researchers, including Shuai Li, a planetary geologist at the University of Hawaiʻi at Mānoa. Understanding the concentrations and distributions of water on the Moon is critical to understanding its formation and evolution, and to providing water resources for future human exploration.
A Chinese Long March 4B rocket launched the Shiyan-6 03 experimental satellite from the Taiyuan Satellite Launch Center on Friday, April 9.
Shiyan-6 was developed by the Chinese Academy of Sciences’ Institute of Microsatellite Innovation. The spacecraft was described in official press reports as being used for space environment detection and related technology experiments.
It was the 365th launch of the Long March series of carrier rockets.
BEIJING (Chinese Academy of Sciences PR) — The exchange of a ‘secret key’ for encrypting and decrypting messages over a distance of 1,120 kilometres is reported in Nature. (Paper)
This achievement is made using entanglement-based quantum key distribution, a theoretically secure communication technique. Previous attempts to directly distribute quantum keys between two ground users under real-world conditions have reached distances of only around 100 kilometres.
While the United States was focused last week on its first domestic flight of astronauts to orbit in 9 years, China was busy with a pair of launches that placed four satellites into space.
A Long March 11 booster launched the Xinjishu Shiyan-G and Xinjishu Shiyan-H technology test satellites from the Xichang Satellite Launch Center on Friday, May 29.
The Xinjishu Shiyan-G satellite was developed by the Shanghai Institute of Microsatellite Innovation, which is part of the Chinese Academy of Sciences. The National University of Defence Technology developed the Xinjishu Shiyan-H satellite.
The satellites will test new Earth observation technology and inter-satellite communications.
On Sunday, a Long March 2D rocket launched the Gaofen-9 (02) remote sensing satellite from the Jiuquan Satellite Launch Center in Inner Mongolia.
The microwave spacecraft is the latest in a series of high-definition Earth observation satellites. Gaofen-9 (02) will be used for a variety of civilian purposes ranging from land use and urban planning to crop estimation and disaster prevention.
The Long March 2D booster carried the HEAD-4 technology and communications satellite as a secondary payload. The spacecraft is owned by HEAD Aerospace Tech Co. Ltd. of Beijing.
China launched its second Kuaizhou-1A booster in four days on Sunday, orbiting a pair of commercial Ka-band satellites.
The launch of the KL-a-A and KL-a-B satellites took place from the Jiuquan Satellite Launch Center in northwest China at 6 p.m. Beijing time.
The Xinhua news agency described the payloads as “global multimedia satellites” designed to test Ka-band communication technology. The Chinese Academy of Sciences’ Innovation Academy for Microsatellites built the spacecraft, which will be used by an unidentified German company.
Kuaizhou-1A is a four-stage solid fuel booster developed by a subsidiary of the China Aerospace Science and Industry Corporation. The rocket is designed to launch micro-satellites on short notice.
Chinese Academy of Sciences to establish a Research Laboratory in Luxembourg
LUXEMBOURG, January 16, 2018 (Luxembourg Government PR) – The Ministry of the Economy and the China National Space Administration (CNSA) signed today a Memorandum of Understanding (MoU) that provides a framework for the development and implementation of scientific, technical, economic and political cooperation between Luxembourg and China in the exploration and use of outer space for peaceful purposes. The areas of potential cooperation include, but are not limited to economic, legal, regulatory and technological aspects of the utilization of space resources.
Furthermore, the Ministry of the Economy, represented by Deputy Prime Minister, Minister of the Economy, Étienne Schneider and the National Space Science Center (NSSC) of the Chinese Academy of Sciences (CAS) signed a cooperation agreement to establish a Research Laboratory of Deep Space Exploration in Luxembourg. The National Space Science Center is China’s gateway to space science. It is the key institute responsible for planning, developing, launching and operating China’s space science satellite missions.
The Research Laboratory of Deep Space Exploration will be established as an independent legal entity in Luxembourg where it will carry out scientific research and technology development and thus contribute to achieving the objectives set forth within the SpaceResources.lu initiative. Other main research fields of the Research Laboratory include universal interplanetary communications network related technology or advanced deep space communications technology. In a first stage, the Research Laboratory will employ at least 5 employees in Luxembourg.
The SJ-10 research probe, launched on April 6, carried over 6,000 mouse embryos in a self-sufficient chamber the size of a microwave oven, according to Duan Enkui, a researcher with the Chinese Academy of Sciences (CAS).
Among them, 600 embryos were put under a high-resolution camera, which took pictures every four hours for four days and sent them back to Earth.
The pictures showed that the embryos developed from the 2-cell stage, an early-on embryonic cleavage stage, to blastocyst, the stage where noticeable cell differentiation occurs, around 72 hours after SJ-10’s launch, Duan said. The timing was largely in line with embryonic development on Earth, he added.
The rest of the embryos loaded on the satellite were injected with fixatives at 72 hours after the launch for studies on the effects of space environment on embryonic development, according to Duan.
