China's lunar rover Yutu-2, or Jade Rabbit-2, discovered an unidentified substance in an impact crater on the far side of the moon.

The discovery was made during Yutu-2's ninth lunar day of exploration on the moon, according to the Lunar Exploration and Space Program Center of the China National Space Administration.

The ground controllers designed a driving route for the rover to allow it to conduct scientific detection to the depth of the impact crater and the distribution of the ejecta, said the center.

"The Yutu-2 rover is expected to bring us more surprises and scientific discoveries," said the center.

The lander of the Chang'e-4 probe and the Yutu-2 rover have resumed work for the 10th lunar day on the far side of the moon after "sleeping" during the extremely cold lunar night.

The lander woke up at 8:26 p.m. Monday, and the rover awoke at 8:30 p.m. Sunday (Beijing Time). Both are in normal working condition, according to the center.
