China's Guowang constellation completes first Arctic-Antarctic video call

Chinese researchers conducted the first publicly reported satellite video call between the Arctic and Antarctic using the Guowang constellation, a state-backed rival to Starlink. This marks a milestone in China's low-Earth-orbit broadband program, which has accelerated partly in response to Starlink's demonstrated military utility. The test signals growing Chinese capability in space-based communications, with potential dual-use implications for defense and global connectivity.
