SAEDNEWS: China has quietly showcased a pioneering space capability by linking two Shijian satellites some 22,000 miles above Earth—an achievement that could signal its entry into orbital refuelling and servicing.
According to Saed News, China’s space programme marked a significant milestone last week when two of its Shijian satellites, Shijian‑21 and Shijian‑25, manoeuvred into close proximity in geostationary orbit and appear to have docked for the first time in Chinese history. In orbit at roughly 35,786 kilometres—the altitude where satellites match Earth’s rotation and hover over a fixed point—these spacecraft reportedly performed a complex rendezvous operation that experts say could presage on‑orbit refuelling, maintenance or even re‑positioning of satellites.
Although Beijing has so far stayed silent on further details, independent satellite trackers observed the two vehicles drawing steadily closer until they became indistinguishable, suggesting a physical connection rather than a mere fly‑by. “This marks one of the most intricate orbital operations to date,” commented a senior engineer cited by Ars Technica, noting that high‑altitude servicing pushes the boundaries of current space technology.
The dual‑use nature of such capabilities has attracted scrutiny. Beyond peaceful applications—such as extending the lifespan of commercial or scientific platforms—the same techniques could conceivably be adapted for disabling or seizing rival satellites, raising strategic concerns among Western powers. The United States Space Force, which plans to begin its own satellite refuelling tests next summer, reportedly dispatched inspection satellites close to the Shijian pair shortly after the manoeuvre. That move underlines Washington’s growing vigilance over Beijing’s advancing orbital toolkit and the emerging contest for space domain supremacy.
