BEIJING -- China on Friday broadcast pictures taken by its rover and lander on the moon's far side, in what its space program hailed as another triumph for the groundbreaking mission to the less-understood sector of the lunar surface.

The pictures on state broadcaster CCTV showed the Jade Rabbit 2 rover and the Chang'e 4 spacecraft that transported it on the first-ever soft landing on the far side of the moon, which always faces away from Earth.

The pictures were transmitted by a relay satellite to a control centre in Beijing, although it wasn't immediately clear when they were taken. Officials with the China National Space Administration said they mark a "total success" for the mission in showing the rover moving away from its lander.

The pictures show a rocky surface with the jagged edge of craters in the background, posing a challenge for controllers in plotting the rover's future travels, the official Xinhua News Agency said.

Among the images is a 360-degree panorama stitched together from 80 photos taken by a camera on the lander after it released the rover onto the lunar surface, Xinhua said, citing Li Chunlai, deputy director of the National Astronomical Observatories of China and commander-in-chief of the ground application system of Chang'e 4.

"From the panorama, we can see the probe is surrounded by lots of small craters, which was really thrilling," Li was quoted as saying.

The space administration also released a 12-minute video of Chang'e 4's landing utilizing more than 4,700 images taken by an on-board camera. The probe is shown adjusting its altitude, speed and pitch as it seeks to avoid obstacles on the ground.

Researchers hope that low-frequency observations of the cosmos from the far side of the moon, where radio signals from Earth are blocked, will help scientists learn more about the early days of the solar system and birth of the universe's first stars.

The far side has been observed many times from lunar orbits, but never explored on the surface. 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 pioneering landing highlights China's ambitions to rival the U.S., Russia and Europe in space through manned flights and the planned construction of a permanent space station.

Well done indeed!!!!

Oh yes, good report.
I am looking forward to more pictures form China Space Agency.

They faded white.

American flags planted on the Moon by US astronauts are still standing four decades on, according to lunar scientists. New photographs show that five out of the six flags put up by crews from Apollo spacecraft during the 1960s and 1970s remain resolutely upright on the Moon's surface.Jul 30, 2012

NASA and China collaborate on Moon exploration
January 18, 2019 by Ivan Couronne

The space agencies of the United States and China are coordinating efforts on Moon exploration, NASA said Friday, as it navigates a strict legal framework aimed at protecting national security and preventing technology transfer to China.




"With the required approval from Congress, NASA has been in discussions with China to explore the possibility of observing a signature of the landing plume of their lunar lander, Chang'e 4, using our @NASAMoon spacecraft's instrument," NASA's associate administrator for the science mission directorate, Thomas Zurbuchen, wrote on Twitter.

Zurbuchen's tweet confirmed a similar statement made Monday by the deputy chief commander of China Lunar Exploration Program, Wu Yanhua.

NASA shared information from a US satellite while China told the Americans about the latitude, longitude and time of the landing "in a timely manner," he said.

The hope was that NASA's Lunar Reconnaissance Orbiter (LRO) could observe the historic touchdown of the Chinese lander on January 3.

NASA provided the planned orbit path of LRO to China, but it turned out the spacecraft was not in the right place at the right time.

"For a number of reasons, NASA was not able to phase LRO's orbit to be at the optimal location during the landing, however NASA was still interested in possibly detecting the plume well after the landing," the agency said in a statement.

"Science gathered about how lunar dust is ejected upwards during a spacecraft's landing could inform future missions and how they arrive on the lunar surface."

Such observations could help astronauts prepare for future missions to the Moon.

NASA's lunar orbiter will pass over the Chang'e 4 landing site on January 31 and will snap pictures, as it did for the Chang'e 3 in 2013.

The agency said significant findings resulting from the cooperation would be shared with the global research community in February at a United Nations space gathering in Austria.

Risk of 'technology transfer'

Since 2011, the US Congress has barred NASA or the White House Office of Science and Technology Policy from using federal funds "to develop, design, plan, promulgate, implement or execute a bilateral policy, program, order, or contract of any kind to participate, collaborate, or coordinate bilaterally in any way with China or any Chinese-owned company."

Exceptions are possible, but NASA must convince Congress and the FBI that the activity would "pose no risk of resulting in the transfer of technology, data, or other information with national security or economic security implications to China or a Chinese-owned company."

The clause was inserted in a US spending bill after a wave of cyber-attacks that was traced to sources in China.

NASA said in its Friday statement that "all NASA data associated with this activity are publicly available," and that NASA's cooperation with China "is transparent, reciprocal and mutually beneficial."

Sino-US cooperation could extend beyond the current lunar project, according to Wu Weiren, chief designer of China's Lunar Exploration Program.

In an interview broadcast by state television CCTV on Sunday, he said NASA scientists had discussed a possible collaboration at an international conference "a few years ago," and that US scientists had asked to extend the lifespan of China's Queqiao relay satellite from three to five years to facilitate the planning of an American moon mission.

And why?

"Later, they said, feeling somewhat embarrassed, that they wanted to land on the far side of the moon too, so if we let (our relay satellite) operate longer they can also use it," he said.

The satellite in question aids in communications with a lander on the far side of the Moon.

NASA scientists had also discussed possibly placing a beacon on the Chang'e 4 probe, he added.

"If we put a beacon there, they also know where to land. I told them our Chang'e 4 can be used as a beacon for you in future," Wu said.

However the US restrictions "might be a much higher barrier to overcome" in ambitious cooperation projects such as a lunar research base that "might involve sharing of technological information," said Henry Hertzfeld, director of the Space Policy Institute at George Washington University.
