China Reports Largest Porphyry Copper-Gold Find in Middle-Lower Yangtze, Opening New Exploration Frontier
China has reported a major copper-gold exploration breakthrough in Anhui province, identifying what researchers describe as the largest porphyry copper-gold deposit yet found in the Middle-Lower Yangtze region and challenging conventional assumptions about where large porphyry systems can form. China’s Ministry of Natural Resources announced the latest exploration results on Sept. 1. The breakthrough centers…

Commercial Space: China’s Domestic Chips Are Winning This Space Race
Ground-based AI chips are a game built around Nvidia’s CUDA ecosystem, and any challenger must contend with developer ecosystems, compute benchmarks and framework compatibility. But in space, an opportunity has emerged to reshuffle the AI compute chip landscape — the competitive dynamics of space-based computing differ from those on the ground, and Nvidia holds no…

Pallas-1 Y1: Another New Rocket from a Chinese Private Launch Company Reaches Orbit
At 10:00 a.m. on September 1, 2026, Pallas-1 Y1, a medium-to-large reusable liquid-propellant launch vehicle developed by Galactic Energy, lifted off from the Dongfeng Commercial Space Innovation Test Zone. The rocket successfully entered its designated orbit as planned, performed normally throughout the flight, and achieved all test objectives, marking the successful completion of the mission.…

How Low Can Satellites Fly? New Opportunities in VLEO and the Companies Already Moving In
Very low Earth orbit, or VLEO, is not a new type of orbital geometry. It is simply the lower portion of low Earth orbit, where satellites fly closer to Earth and encounter a comparatively denser residual atmosphere. Commercial space companies are paying renewed attention to this regime for a straightforward reason: Earth observation satellites can…

Star–Air–Ground–Borehole Exploration Technology Leads to New Breakthrough in Gangdese Mineral Prospecting
Recently, the China Aero Geophysical and Remote Sensing Center for Natural Resources’ Qinghai–Tibet Plateau airborne geophysical exploration team discovered the Changlong iron-rich tin polymetallic deposit for the first time in an unexplored area of the western Gangdese metallogenic belt. The discovery took just six months from the initial flight survey to the confirmation of mineralization,…

Top ten frontier scientific issues in the field of remote sensing science and technology
In early July, Academician Zhang Bing and his co-authors published an article in the Journal of Remote Sensing, summarizing and discussing 10 frontier scientific questions in remote sensing science and technology. Original article: https://www.ygxb.ac.cn/zh/article/doi/10.11834/jrs.20266221/ Abstract Remote sensing is a fundamental technology for understanding the Earth system. The integration of coordinated satellite-airborne-tower-ground observations with artificial intelligence,…

How High and How Inclined Should a Satellite Fly? How Orbital Altitude and Inclination Are Determined
Why do some satellites skim relatively close to Earth and complete an orbit in just over 90 minutes, while others remain above the equator and appear motionless in the sky? And why do some Earth observation satellites designed for near-global coverage deliberately use “retrograde” orbits with inclinations greater than 90 degrees? The answer lies in…

Six Key Metrics for Assessing China’s Reusable Rockets
China’s reusable-rocket race has reached a turning point. With the Long March-10B completing an offshore net-capture recovery and Zhuque-3 Y2 landing its first stage on deployable legs, the country has demonstrated that it can recover intact boosters from orbital-class missions. But landing a rocket is not the same as reusing it—and reuse does not automatically…

Top 10 Frontier Questions in Remote Sensing Unveiled by Chinese Academy of Sciences Institute
The Aerospace Information Research Institute of the Chinese Academy of Sciences (AIRCAS) announced on August 28 that the Second National Conference on Remote Sensing Geography had opened that day in Kashi, Xinjiang, where the “Top 10 Frontier Questions in Remote Sensing Science and Technology” were officially unveiled. Academicians and experts said remote sensing in China…

How Is Every Field Accurately Verified? China Uses Remote Sensing for Its Fourth National Agricultural Census
Remote sensing technology has given agricultural censuses “eyes in space,” but satellite imagery alone cannot produce agricultural data with 100% accuracy. Misaligned field boundaries, omitted or duplicated polygons, crop misclassification, and cloud cover obscuring ground conditions are all unavoidable challenges in remote sensing interpretation. These issues emerged during the remote sensing survey verification for China’s…
