China's probe sends moon's far side image

China's lunar probe has sent the first panoramic image of its landing site since its historic arrival on the far side of the moon, showing the cratered landscape it is exploring.

The Chang'e-4 mission -- named after a moon goddess -- made the world's first soft landing on the moon's far side on 3 January, a major step in China's ambitions to become a space superpower.

A rover dubbed Yutu-2 -- the name of the moon goddess's pet, the 'Jade Rabbit' -- successfully separated from the lander and drove onto the moon's surface Thursday.

A camera deployed on Chang'e-4 took a photo that was released by the China National Space Administration (CNSA) on Friday.

The picture shows the grey moonscape, the lander and the rover with the track marks it left behind. The image is a circular, 360-degree shot, which scientists used to create another wide panoramic picture.

"Researchers have completed the preliminary analysis of the lunar surface topography around the landing site based on the image taken by the landing camera," the CNSA said in a statement.

Chang'e-4, the Yutu-2 and the Queqiao relay satellite that beams data back to Earth are "in a stable condition, and all work was carried out as planned," the statement said.

The 140-kilogram (308-pound) rover resumed activities on Thursday after being on "stand-by mode" for five days.

Chang'e-4 landed within the South Pole-Aitken (SPA) Basin, the largest and deepest impact crater in the solar system.

Scientists have said the far side is a key area for solving several unknowns about the moon, including its internal structure and thermal evolution.

This is the second Chinese probe to land on the moon, following the first Yutu rover mission on its Earth-facing side in 2013.
