China to build ground stations in Antartica to support ocean monitoring satellites
China, only the third country to put a man in space after the Soviet Union and United States, is to build ground stations on Antarctica to back its network of ocean monitoring satellites, state media said on Thursday.
Renders of the 43.95 million yuan ($6.52 million) project show four radome-covered antennas at China’s Zhongshan research base in East Antarctica. It is unknown if these are new and additional to antennas already established at the base.
The antennas will assist data acquisition from Chinese satellites that orbit in polar and near-polar orbits. Satellites in these orbits are visible near the poles multiple times a day, allowing more frequent opportunities for downlink than with stations at lower latitudes.
China has already launched eight Haiyang series ocean observation satellites into sun-synchronous orbits between 2002 and 2021, and plans more in the coming years. The first new-generation Haiyang-3 satellite is scheduled for launch this year, according the China’s main space contractor, CASC.

China Satellites and Balloons used for Espionage?
China’s global network of ground stations to support a growing number of satellites and outer space ambitions has drawn concern from some nations that it could be used for espionage, a suggestion China rejects.
In 2020, Sweden’s state-owned space company, which had provided ground stations that helped fly Chinese spacecraft and transmit data, declined to renew contracts with China or accept new Chinese business due to “changes” in geopolitics.
The United States military shot down a Chinese spy balloon on Saturday that had spent the last week traversing the country. The balloon, which spent five days traveling in a diagonal southeast route from Idaho to the Carolinas, had moved off the coast by midday Saturday and was shot down within moments of its arrival over the Atlantic Ocean.
One of two F-22 fighter jets from Langley Air Force Base fired a Sidewinder air-to-air missile, downing the balloon, which was flying at an altitude of 60,000 to 65,000 feet. The F-22s were at 58,000 feet, with other American fighters in support.
In announcing the cancellation of his trip to China, U.S. Secretary of State, Antony J. Blinken said the entry of the spy balloon was a “clear violation of U.S. sovereignty and international law.”

No technical details of the project were given in the report, though China Space News published two accompanying illustrations of an artist’s rendering that shows four ground stations at Zhongshan, located by Prydz Bay in East Antarctica, south of the Indian Ocean.
The project was part of broader initiatives aimed at building China’s marine economy and turning China into a marine power, according to China Space News.
