"The rover rolled only a small step on to the Moon, but it represented a huge stride for the Chinese nation". He posted: "Congratulations to China's Chang'e-4 team for what appears to be a successful landing on the far side of the Moon".
The collection of data from the invisible side of the moon began with the Jadehase 2 robotic vehicle, the vehicle carried by the Chinese satellite Chang'e 4, which for some hours has been laid on the moon side that we cannot see.
Three nations - the United States, the former Soviet Union and more recently China - have sent spacecraft to the near side of the moon, but the latest landing is the first on the far side.
"The process was recorded by the camera on the lander and the images were sent back to the Earth via the relay satellite "Queqiao"," the report said, quoting China National Space Administration (CNSA).
It then released a rover, named Yutu-2, which rolled out onto the surface down a ramp.
The rover, also known as Jade Rabbit 2, has six powered wheels, so it can keep working even if one fails, according to The Associated Press. The vehicle can slant up to 20 degrees and overcome obstacles up to 20 centimeters in size.
In Chinese folklore, Yutu is the white pet rabbit of Chang'e, the moon goddess who lent her name to the Chinese lunar mission. It is popularly called the "dark side" because it can't be seen from Earth and is relatively unknown, not because it lacks sunlight.
The rover and lander are carrying instruments to analyse the unexplored region's geology. The country aims to land a crewed flight on the moon in the coming decade.
The pioneering achievement is another demonstration of China's ambitions to be a space power.
Every semester, Purdue University lunar and planetary scientist Jay Melosh demonstrates how the far side gets light using a bright light as the sun and students playing the roles of the moon and the Earth.
Because the moon is tidally locked with Earth, the same half always faces Earth.
Chang'e-4 includes two main parts: the main lander weighing about 1,088 pounds and a 136-kilogramme rover.
