The investigation, Chang 'e-4, entered an orbit planned on Sunday "to prepare for the first soft landing on the far side of the moon," the news agency said, citing China's national space administration. It is not stated when the landing will occur.
The moon is locked locked to Earth, rotating at the same speed as orbiting our planet, so that the far side – or "the dark side" – is never seen from Earth. The spacecraft had seen the far side of the moon, but no one had landed on it. China launched a Chang probe e-4 earlier this month, which was carried by a Long March-3B rocket.
