Chang'e 4

Parents

2019 During China's 2019 Chang'e 4 mission, NASA collaborated with China to monitor the moon lander and Yutu 2 rover on the lunar far-side using NASA's Lunar Reconnaissance Orbiter. NASA was able to do so by getting congressional approval for the specific interaction and sharing data with researchers globally.[11] NASA stated: The statutory prohibition on NASA’s use of appropriated funds for bilateral cooperation with China…does not apply to activities that NASA has certified to Congress, [which] do not pose a risk of resulting in the transfer of technology, data or other information with national security or economic security implications to China, and that do not involve knowing interactions with officials who have been determined by the U.S. to have direct involvement with violations of human rights. In accordance with the law, NASA made the appropriate certification to Congress for this activity.[11]
