Unlike NASA's history-making mission to Mars in November and the agency's flyby of the mysterious Kuiper Belt Object 2014 MU69 on New Year's Day, China's landmark landing wasn't televised. Social media accounts on Chinese giant Weibo reported that the lunar probe touched down at around 6:26 p.m. PT but confirmation of the reports was hard to come by. After tweets by Chinese State-owned media outlets China Daily and China Global Television Network made their way online, the Twittersphere was abuzz... but the tweets were quickly deleted.

According to Andrew Jones, a journalist reporting on the Chinese space program, Chang'e 4's descent required "laser ranging and optical cameras for navigation, velocity and coarse hazard avoidance." Practically, this meant Chang'e 4 was on its own as it descended to the surface with its important scientific payload, on a side of the moon marked by rugged terrain.
