Take a break! China's Chang'e-4 probe in 'dormant', after walking over 1,000m on moons far side

China's Chang'e-4 lunar probe switched to dormant mode on January 15. It has been working more than three years on the far side of the moon, with its rover Yutu-2 traveling over 1,000 meters. So far, Yutu-2 lunar rover has traveled more than 1,000 meters on moon, with an average of 40 meters for each lunar day. It is the very space vehicle that has worked for the longest time on the far-side of the moon.
