All systems go as a Chinese spacecraft and the rover puts the observation equipment into operation after making a first landing on the far side of the moon, said the Chinese National Space Administration.
Jade Rabbit 2 rover has managed to establish a digital transmission link with a retransmission satellite that sends data back to the Beijing control center, the space agency said in a late Friday post on its website.
The rover's radar and panoramic camera were turned on and working normally, he said. An agency photo showed that the rover stopped at a point not far from the place where the Chang's 4th spacecraft reached on Thursday.
Chang 4, named after the goddess of the Chinese moon, is the first craft that makes a soft landing on the distant side of the Moon, which is heading for the Earth. Previous landings, including one by China Chang's 3 in 2013, were on the near side.
After shipping the rover from a ramp, the spacecraft deployed three radio antennas with a low frequency of 5 meters, said the Spanish space agency. Changes 4 also sent back images with a topographic camera.
Researchers hope that the low frequency observations of the distant side of the cosmos, blocking the Earth's radio signals, will help scientists learn more about the early days of the solar system and even the birth of the first stars of the universe.
Harvard University astronomer Avi Loeb, however, noted that the relay satellite needed to send information from the far side also contaminates the sky.
"As long as we keep it clean from radio interference, the distant part of the moon is very good for radio astronomy," he said.
The distant part has been observed several times in the lunar orbits, but has never been explored on the surface. It is popularly called the "dark side," because it can not be seen on Earth and is relatively unknown, not because it has no sunlight.
"It's just the far side, it may be dark or light," Loeb said, according to the time of day.
The pioneering landing highlights China's ambitions to rival US, Russia and Europe. Both the Chinese space community and the public were proud of the achievement, with some comparisons compared to the United States.
China's space program occupies America's position, but has taken important strides over the past 15 years, including human crew flights and a space laboratory that is seen as a precursor to plans for a space station.
