A groundbreaking study conducted by Chinese scientists on a 2-gram lunar soil sample from the Chang’e 6 mission has uncovered rare CI chondrite impact residues, shedding light on the mass transfer processes within the inner solar system and offering fresh perspectives on the distribution and evolution of water on the moon. The research, spearheaded by a team from the Guangzhou Institute of Geochemistry under the Chinese Academy of Sciences, was published in the prestigious journal Proceedings of the National Academy of Sciences on October 21, 2025. CI chondrites, also known as Ivuna-type carbonaceous chondrites, are exceptionally rare meteorites with a primitive chemical composition akin to the sun’s nonvolatile elements. These meteorites, rich in water and volatiles, primarily formed in the outer solar system and migrated into the asteroid belt during the early stages of planetary formation. The discovery of CI chondrite residues in the lunar soil suggests that such materials can travel to the Earth-moon system. Furthermore, the research team posits that the water with positive oxygen isotope characteristics previously detected in lunar samples likely originated from impacts by these meteorites. This revelation opens new avenues for future studies on the sources and evolution of water on the lunar surface.

Two distinguished Chinese scientists have been appointed to lead the UNESCO Chair for Mountain Disaster Risk Reduction and Resilience, a significant initiative aimed at addressing the escalating challenges posed by natural disasters in mountainous regions. The announcement was made during the unveiling ceremony held in Beijing on Sunday, coinciding with the opening of the 2nd International Conference on Climate Change and Disaster Risk.

Cui Peng, an academician of the Chinese Academy of Sciences and chief scientist at the China-Pakistan Joint Research Center on Earth Sciences, has been named the chair of the project. Yang Saini, executive director of the Integrated Research on Disaster Risk program and a professor at Beijing Normal University, will serve as assistant chair.

The initiative comes at a critical time when global climate change is exacerbating the frequency and intensity of natural disasters, particularly in mountainous areas. Liu Weidong, director-general of the international cooperation bureau of the Chinese Academy of Sciences, highlighted the growing complexity of these disasters, which are becoming harder to predict and mitigate.

Cui Peng emphasized the vulnerability of mountainous regions, which account for 70% of China’s territory and 30% of the global land area. He stressed that these regions must not be overlooked in the pursuit of high-quality development. The UNESCO Chair aims to reduce the loss of life and property caused by disasters and explore ways to integrate disaster reduction with regional economic development.

Yang Saini noted that China will leverage global resources and share its extensive experience in disaster risk reduction through the UNESCO platform, while also adopting effective international practices. Shahbaz Khan, director of the UNESCO Beijing Office, congratulated the scientists and underscored the importance of the UNESCO Chair program in advancing the United Nations Sustainable Development Goals and building capacity in the Global South.

NASA is intensifying its efforts to return humans to the Moon by soliciting new bids for its Artemis program, as SpaceX, Elon Musk’s aerospace company, faces delays. NASA Administrator Sean Duffy announced the move on Monday, emphasizing the urgency to compete against China’s advancing lunar ambitions. ‘We’re going to have a space race among American companies to see who can get us back to the Moon first,’ Duffy stated during an interview on Fox News. He revealed plans to open the contract to other competitors, including Jeff Bezos’ Blue Origin, to accelerate progress. SpaceX currently holds the contract for the fifth Artemis mission, but delays have prompted NASA to seek alternatives. Duffy, who also serves as the US Transportation Secretary, stressed the importance of innovation and competition in maintaining US dominance in space exploration. The Artemis program, initiated during President Donald Trump’s first term, aims to return astronauts to the Moon and eventually voyage to Mars. Despite setbacks, NASA remains committed to its timeline, with the Artemis 2 mission, featuring a crew of three US astronauts and one Canadian, scheduled for April 2026. This mission will mark the first crewed lunar flyby in over 50 years. NASA officials, including Lakiesha Hawkins, have reaffirmed their dedication to meeting these ambitious goals, even as they navigate challenges and rising global competition.

Chinese researchers have achieved a groundbreaking advancement in spectroscopic imaging, developing a technique that combines exceptional resolution with a panoramic view, revolutionizing the way the universe is scanned. Named RAFAEL (Yuheng in Chinese), this innovative technology, created by a team from Tsinghua University, is compact enough to fit on a chip the size of a mobile phone SIM card. The study, published in the prestigious journal Nature, highlights the chip’s ability to capture full spectral data with sub-angstrom resolution for approximately 10,000 stars per second. Professor Fang Lu, the lead researcher, emphasized that this technology could reduce the time required to compile complete spectra for all stars in the Milky Way from thousands of years to under a decade. The chip’s miniaturized design also makes it suitable for mounting on satellites or deep-space probes, paving the way for unprecedented spectral maps of the universe. The core innovation lies in resolving the long-standing trade-off between resolution and field breadth in spectral imaging. By employing advanced computational imaging methods and reconfigurable integrated photonics based on lithium niobate, the team achieved snapshot spectroscopy with ten-megapixel-level spatial resolution and sub-angstrom spectral resolution across visible and near-infrared wavelengths. This breakthrough significantly surpasses existing international counterparts, improving spectral resolution by two orders of magnitude. The technology’s practical applications extend beyond astronomy to fields such as material identification, plant health, autonomous driving, and atomic spectroscopy. Efforts are underway to implement the technique on giant telescopes at observatories in China and Spain. Professor Fang described the study as a beginning, showcasing how intelligent photonics can continue to push the boundaries of what light can reveal.
