The US banned the space agency from working with China and its state-owned companies out of concerns regarding national security and technology transfers. As a result, China was locked out of the International Space Station because NASA is one of the participating bodies. More recently, scientists from other countries such as Germany and Sweden who were helping China with its exploration of the far side of the Moon were cautious of not falling afoul of US export controls on sensitive technology.
China’s space agency, however, announced that the two countries had shared data on its exploration of the far side of the Moon. “Cooperation is the joint will of scientists,” said Wu Yanhua, deputy director of China’s National Space Agency in a press conference yesterday (Jan. 14). He also noted that both organizations have met “frequently.”
According to Wu, NASA had proposed to use its Lunar Reconnaissance Orbiter (LRO), which orbits the Moon, to observe the landing of the Chang’e-4 spacecraft on the lunar far side. Wu said that China had told NASA the exact landing time and position of the spacecraft, but the LRO wasn’t in the right position to do so as it wasn’t able to adjust its orbit with what little fuel it had left. Before the touchdown on Jan. 3, the LRO managed to capture pictures of the landing site.
NASA did not respond to requests for comment from Quartz regarding details of the cooperation and whether data sharing violates the ban.
However, NASA’s administrator, James Bridenstine, has said that the agency shares data with China. “When they do a science mission to the Moon, we’re hopeful they will be able to share with us the data they receive, and when we do a mission to the moon, we can share data with them,” Bridenstine told Quartz (paywall) in an earlier interview. “Understanding and characterizing the Moon and doing that kind of science is in the interest of all humanity. It’s not something any one country should try to retain for itself.”
