The State Administration of Science, Technology and Industry for National Defense2 says the transition was made while the probe transited3 the dark side of the moon at 9:20 p.m. on Tuesday, Beijing time. The transition took around four minutes. Chang’e-3 will now prepare for a soft-landing on the moon’s surface. T
