A tall, powerful antenna looks up to the sky from the Patagonia desert in Argentina. It is part of a Chinese space station built there over 200 hectares. A 2.5-meter high fence surrounds the area. The space station came with a promise of a visitor’s center to explain its purpose. China’s space program, including the space station, is run by its military, the People’s Liberation Army. The Chinese foreign ministry says the station in Patagonia is for civilian use only and is open to the public and media. The station became operational in April. Chinese media have presented the station as a peaceful space observation and exploration tool. They also say it played a key role in China’s landing of a spacecraft on the dark side of the moon in January. The space station operates with little oversight by the Argentine officials. That is the conclusion of international law experts who reviewed hundreds of pages of Argentine government documents obtained by the Reuters news agency.
