Scientists at the Xinjiang Technical Institute of Physics and Chemistry in Urumqi have developed a material from artificial lunar dust that might be strong enough to build a base on the moon, and could potentially be made using volcanic rock on site. The team turned the artificial dust into a high-performance construction material called basalt fibre. Put through testing, they said it achieved a tensile strength of up to 1.4 gigapascals - or 1,400 megapascals. The team used artificial lunar dust mainly sourced from the Changbai Mountain, an active volcano on the Chinese-North Korean border. The dust is about 48 per cent silicon dioxide and 17 per cent aluminium oxide - almost identical to the composition of samples brought back from the Moon by Nasa’s Apollo 14 mission in 1971.

The Xi'an Satellite Control Center's tests have shown links among the satellites of the BeiDou Navigation Satellite System (BDS) are stable to ensure that the constellation can be completed as scheduled. The tests showed that the inter-satellite links meet the demands of the construction of the global system, said Yuan Yong, a senior engineer from the control centre. He said that the tests, lasting for more than two years, covered 29 satellites of the BDS-3 system.

On 5 June China and Serbia signed a memorandum on space technology. The memorandum was signed by Zhang Kejian, Director of the China National Space Administration, and Nenad Popovic, Serbian Minister in charge of innovation and technological development, via a video conference. Zhang said the memorandum is in the common interests of both countries, adding that as many scientists as possible will engage in joint space projects. "Our goal is to put the flag of Serbia on the spacecraft that we will jointly design," he announced.
According to the Serbian government, the document will envisage the "improvement of bilateral cooperation between Serbia and China in the development and use of space technology, satellite systems and the Earth Observing System, with applications in the field of smart agriculture, telecommunications, ecosystems, remote sensing systems and geolocation positioning."

11 items from Tibet including barley, forage grass, rose rhodiola, lemon, and graphene that were carried by the re-entry module of the new manned spacecraft in early May are now available for testing in labs, China Tibet Online reported. The items are of interest in studies of the germination characteristics of seeds, crop output and plant growth cycles. Wang Junjie, a researcher at the National Astronomical Observatory of China, said the 11 items were taken to space to determine whether they would mutate in an environment of cosmic radiation, charged particles and zero gravity.

Chinese researchers have designed an improved remote sensing method for more efficient landslide monitoring. Synthetic aperture radar (SAR) remote sensing is a potential technique for long-term monitoring of landslide-prone areas. Traditional pixel offset tracking methods work well for fast-moving landslides but still have some limitations. The researchers from the Chinese Academy of Sciences proposed the improved offset tracking method to optimize a more efficient workflow, as well as an improved algorithm based on homogeneous samples.
