On 17 May 2020, the Chang'e 4 mission on the far side of the Moon has been operational for 500 days. Yutu 2 accumulated 447.68 m of traversing the lunar surface and is currently positioned at a distance of 292 m from the lander. Yutu 2 woke up at 11:53 BJT on 16 May to continue operation for the 18th lunar day. The lander woke up at 3:25 BJT on 17 May.
