China opens moon rock samples to US amid trade war
Listen to article
China has granted scientists from six countries, including the United States, access to lunar samples collected by its Chang'e-5 mission, marking a rare instance of scientific cooperation between Beijing and Washington despite ongoing trade disputes.
The China National Space Administration (CNSA) said on Thursday that researchers from two NASA-funded American institutions — Brown University and Stony Brook University — would be allowed to study the Moon rocks, which were retrieved in 2020.
Institutions in France, Germany, Japan, Pakistan and the UK also secured approval to examine the samples.
The CNSA's chief, Shan Zhongde, described the lunar material as 'a shared treasure for all humanity,' according to state-run media.
He added that China aims to expand international cooperation in space exploration under its Belt and Road Initiative.
The US has long prohibited NASA from working with Chinese space entities without explicit approval from Congress.
The 2011 Wolf Amendment restricts bilateral cooperation due to national security concerns, effectively barring Chinese scientists from accessing US-collected lunar samples.
John Logsdon, former director of the Space Policy Institute at George Washington University, informed that the exchange of Moon samples have "very little to do with politics".
'This is international cooperation in science, which is the norm,' he said. 'It has nothing of military significance.'
Logsdon also noted that the Chang'e-5 samples are particularly valuable because they appear to be a billion years younger than those collected during the Apollo missions.
This could suggest more recent volcanic activity on the Moon than previously thought.
Efforts by US and Chinese space officials to directly exchange lunar material reportedly stalled last year, but the approval of international study applications signals a shift towards openness.
Despite high tariffs on both sides — with US duties on Chinese imports reaching up to 245% and China retaliating with 125% tariffs — scientific engagement remains a rare bright spot.
'I believe China's circle of friends in space will continue to grow,' said Shan.

After DeepSeek, China's JC10 moment
The writer heads the independent Centre for Research and Security Studies, Islamabad. He is currently a visiting Research Fellow at Fudan University, Shanghai Listen to article Amidst the intricate tapestry of Chinese intellectual and academic circles, a distinct sense of pride permeates the nation's achievements. The recent, albeit perilous, Indo-Pak confrontation (May 7-10) serves as a catalyst for this sentiment. As the ongoing war of information and propaganda intensifies, Chinese intellectuals eagerly celebrate the groundbreaking milestones achieved through their technological advancements, particularly in the domains of AI-driven satellites, jet fighters and missiles, in collaboration with the Pakistan Air Force. They find amusement in the spotlight that has been bestowed upon their defence hardware, which emerged triumphant after four days of engagement. Following the DeepSeek, Beijing and Shanghai have experienced a collective sense of triumph akin to the JC10-PL15 Moment for most academics. This moment is fueled by the successful demonstration of their technology, which has garnered widespread attention. An excerpt from The National Interest elucidates the recriminations between the Indian and French governments over access to source codes for the Rafale jets. These events have engendered both anger in India and amusement in Beijing. Chinese social media platforms have been abuzz with these developments, as they find amusement in the circumstances. After all, why should they not? Chinese weapons and warplanes exceeded expectations during the conflict. When news emerged of India's inability to access Dassault's source code, coinciding with India's capture of an intact Chinese PL-15 missile, one of Beijing's "wolf warrior", diplomats took to X to mock New Delhi: "India invested $288 million per Rafale, yet they lack access to the source code. Furthermore, they assert their ability to 'extract the software' from the wreckage of a PL-15 missile. However, they are unable to access the fundamental functions of their own Rafale jets." While exuberance is understandable, it should not be construed as complacency. The Indo-Pak confrontation has only served as a catalyst for further pursuit of excellence through meticulous deliberation and strategic planning, both domestically and internationally. Discussions at universities, think tanks and official quarters continue to be influenced by the recent four-day conflict between nuclear rivals, India and Pakistan. The episode appears to have energised Chinese academia to engage in forward planning and explore options for enhanced and more effective cooperation with partner countries, particularly Pakistan. Why is this the case? Consistency is ensured by the Communist Party, which underpins China's entire political economy and the intellectual growth led by a dedicated leadership that ascends the political ladder through a rigorous accountability process. Only those with the utmost integrity and demonstrated commitment to the party and the people are successful in this process. What unites these individuals is an unwavering faith in the well-being of citizens and the belief that investment in human resources is essential for progress. Whether it is the iconic Great Wall in Beijing or Shanghai, Yiwu or Guangzhou, China's defence hi-tech capabilities, dozens of high-altitude glass bridges, or Shanghai's Global Finance Center, they all convey the same message: unwavering policy consistency, honesty and visionary leadership, coupled with absolute focus on the welfare and education of the people. These factors have transformed China and propelled it to a position where it is now asserting itself even against the United States. While President Trump's bullying tactics were met with resistance, China agreed to engage in diplomatic discussions but refused to yield. The recent grand summit in Kuala Lumpur, which involved China, ASEAN and the GCC, provided a glimpse of Beijing's unwavering commitment to peaceful engagement and win-win cooperation rather than coercive diplomacy. While President Biden's Build Back Better World initiative has seemingly lost momentum, the Belt and Road Initiative (BRI) continues to thrive and attract an increasing number of countries. Since Xi Jinping assumed the presidency in 2012, China has invested hundreds of millions of dollars in research and capacity building. Notably, the Chinese military has undergone a significant reduction in personnel, with nearly 300,000 personnel being eliminated. Additionally, the generals have been instructed to prioritise their professional duties and future challenges rather than engaging in commercial ventures. The People's Liberation Army (PLA) must maintain its focus on excellence and avoid any involvement in commercial activities. Both the PLA and the Communist Party have endured severe purges of high-ranking officials for corruption, inefficiency and betrayal of their responsibilities. The driving force behind China's current success lies in an ecosystem anchored in solid planning, facilitated knowledge and skill development, and the pursuit of excellence. This system operates on merit and celebrates knowledge and skills. Coincidentally, as I was concluding this article, a public service text message arrived on my mobile device, reminding us that May 30th is the 9th National Science and Technology Workers' Day and coincides with the 25th National Science and Technology Activity Week. "We extend our utmost respect to all science and technology workers. Let us harness innovation as our guiding principle and hard work as our propulsion, collectively constructing the vision of a robust nation through science and technology," said the message from the ministry. This inspiring message serves as a testament to the recognition of science and technology as the indispensable key to self-sufficiency and competitiveness, positioning China at a significant advantage over other nations. It is unsurprising that China is experiencing a surge of technological achievements that few countries can boast of - something that instills a sense of confidence and fosters national pride.

China launches first space mission to retrieve asteroid samples
An artistic concept of Tianwen-2 spacecraft near an asteroid. PHOTO: ORBITAL TODAY WEBSITE Listen to article China embarked on Thursday on its first mission to retrieve samples from a nearby asteroid, with the nighttime launch of its Tianwen-2 spacecraft, set to make the fast-growing space power the third nation to fetch pristine asteroid rocks. The decade-long mission is the latest in recent space efforts that include landing robots on the moon's far side, running a national space station in orbit and investing heavily in plans to send humans to the moon by 2030. The Long March 3B rocket lifted off at about 1:31 a.m. from the Xichang satellite launch center carrying the Tianwen-2 robotic probe. Over the next year it will approach the small near-Earth asteroid 469219 Kamoʻoalewa, which is between 9 million miles and 24 million miles (15 million km and 39 million km) distant. China's official news agency Xinhua confirmed the launch of Tianwen-2, calling it a "complete success". Tianwen-2 is set to reach the asteroid in July 2026 and shoot a capsule packed with rocks back to Earth for a landing in November 2027. Then it will fly to its second target, main-belt comet 311P/PanSTARRS, on a journey lasting years, as the comet's closest distance to Earth is about 87 million miles. Located in the main asteroid belt between Mars and Jupiter, Comet 311P is far closer to the Sun than the region where typical comets originate. The odd location makes it unlikely to have the surface ice of typical comets that, once vaporised, forms their characteristic tails. Tianwen-2 will make in-depth studies of the main features of Kamoʻoalewa and 311P, including possibly the material ejected by the latter, an official of the China National Space Administration (CNSA) said. Returning samples from Kamo'oalewa will be far more challenging than China's successful lunar missions, mainly because the asteroid's gravity is much lower than that of the moon, making landing and sampling much harder. Japan's Hayabusa, which fetched samples from a small asteroid in 2010, was the world's first such mission, followed by its Ryugu mission of 2019. In 2020, the first US asteroid retrieval mission, OSIRIS-REx, brought back samples from the Bennu asteroid. Kamoʻoalewa is known as a quasi-satellite of Earth, a close celestial neighbour that has orbited the sun for roughly a century, NASA says. Its size is anywhere between 120 feet and 300 feet (40 m and 100 m). Tianwen-2's predecessor, Tianwen-1, another uncrewed spacecraft launched in 2020, was China's first mission to Mars, successfully landing on a vast plain known as Utopia Planitia after a six-month journey. China is already planning its third interplanetary mission, Tianwen-3, scheduled tentatively for 2028, which could make it the first country to retrieve samples from Mars. Last month CNSA announced payload capacity of 20 kg (44 lb) for foreign countries and research institutions aboard the orbiter and lander that will explore the red planet.

Quantum imaging breakthrough by Brown students enables 3D holograms without IR cameras
In a remarkable leap for microscopic imaging, two Brown University undergraduates have developed a novel quantum technique that generates high-resolution 3D holograms without the need for infrared cameras. Their work, published on Brown University's website, could offer a cost-effective breakthrough in biological imaging and holography, addressing a persistent technical challenge known as phase wrapping. The method, dubbed 'Quantum Multi-Wavelength Holography,' was unveiled by Moe (Yameng) Zhang and Wenyu Liu at the recent Conference on Lasers and Electro-Optics. Working under the guidance of senior research associate Petr Moroshkin and Professor Jimmy Xu, the pair built a system that uses visible light entangled with infrared photons to capture three-dimensional images of microscopic objects. Traditionally, high-resolution imaging of biological materials requires infrared wavelengths due to their ability to penetrate soft tissues safely. However, infrared cameras are expensive and not widely accessible. The students' technique bypasses this by using visible light detectors while still benefitting from infrared illumination. 'You could call this infrared imaging without an infrared camera,' said Xu. 'It sounds impossible, but they did it. And they did it in a way that enables great depth resolution in the images it produces.' The technology hinges on quantum entanglement, a phenomenon where two particles remain interconnected regardless of the distance between them. In this system, the 'idler' photon probes the object while the 'signal' photon — its entangled partner — is measured to reconstruct the image. Using a nonlinear crystal, the team generated photon pairs with one in the infrared spectrum and the other in visible light. 'Infrared wavelengths are preferred for biological imaging, but we can't always afford the tools,' said Liu, a senior studying engineering physics and applied mathematics. 'Our method lets us use inexpensive silicon detectors while still collecting deep, meaningful data.' One of the biggest hurdles they faced was phase wrapping — a problem in which imaging systems mistake deeply contoured surfaces as shallow due to the periodic nature of wave-based measurements. To overcome it, the students employed two sets of entangled photons at slightly different wavelengths. This generated a synthetic wavelength nearly 25 times longer than the originals, greatly enhancing depth measurement. 'By using two slightly different wavelengths, we effectively create a much longer synthetic wavelength,' Liu explained. 'That gives us a much larger measurable range, applicable to cells and other biological materials.' To validate their system, the team created and successfully imaged a 1.5-millimetre metallic 'B,' an homage to Brown University. The image, rendered through indirect photon detection, proved that their method could yield detailed and accurate 3D representations. Zhang, a junior studying engineering physics, said the experience of meeting experts in the field at the conference was as rewarding as the research itself. 'We had been reading papers by pioneers in this field, so it was great to attend the conference and meet some of them in person.' Liu's contribution earned him the School of Engineering's Ionata Award, which recognises exceptional creativity in independent projects. Their work is being hailed as an important step towards more accessible, scalable, and precise quantum imaging — one that could reshape how researchers visualise the microscopic world.
