PALLAS-1 Completes Successful Maiden Flight: Why Did Galactic Energy Stick With LOX/Kerosene?
On the morning of September 1, PALLAS-1 Y1 lifted off from Jiuquan and successfully entered its planned orbit. For Galactic Energy, the mission marked not only the debut of a new launch vehicle, but also the company’s transition from small solid-fuel rockets to a medium-lift liquid-fuel rocket. The rocket also embodies a choice that is…

From Detecting Change to Assessing Risk: Satellite Remote Sensing for High-Mountain Hazards
On August 26, 2026, a cascading debris-flow disaster originating on the Nepal side of the China–Nepal border struck Gyirong Port in Xizang, China. Based on pre- and post-event high-resolution satellite imagery, seismic reports, and imagery transmitted from the affected area, an expert working group organized by China’s Ministry of Natural Resources preliminarily assessed that the…

Why Are Satellites “Oxidized” in Near Vacuum? How Aggressive Is Atomic Oxygen and How Can It Be Prevented?
A satellite entering low Earth orbit (LEO) may lead people to assume that there is almost no atmosphere outside, so how could oxygen still exist? However, for spacecraft operating in LEO, oxygen is not only present but can become one of the most challenging environmental factors for materials. It can gradually thin polyimide films, create…

Hainan Could Become the Hub of China’s Commercial Space Future
The global launch industry is entering a new phase, one defined less by whether rockets can reach orbit and more by how quickly launch capacity can scale. Firefly Aerospace CEO Jason Kim recently pointed to a widening imbalance between the number of satellites waiting to fly and the amount of launch capacity available to carry…

What Does “Y” Mean in Chinese Rocket Designations?
Whenever China launches a rocket, its name often includes the Chinese character “遥” (Yao, Y). Examples include the Long March 2F Y23, Long March 5 Y6, and Zhuque-3 Y2 launch vehicles. So what exactly does “Y” mean, and where did this naming convention come from? “Y” is short for “Yaoce” (遥测, telemetry), and its origins…
