China hopes to grow potatoes on far side of the moon

China says it has opened a "new chapter in lunar exploration" after sending a rover towards the far side of the moon.
The Chang'e-4 lunar probe was launched on a Long March 3B rocket from the southwestern Xichang launch centre, and is expected to reach its destination sometime around the turn of the year.
While the terrain on the near side of the moon has many flat areas to touch down on, the far side is rugged and mountainous.
