Chang'e-6 - China's latest leap of moon exploration - has claimed full success, as the returning capsule of the craft, carrying the first batch of lunar samples collected from the far side of the moon in human history, safely touched down in designated landing site in the Siziwang Banner, in North China's Inner Mongolia Autonomous Region on Tuesday afternoon at 2:07 pm.

Chinese President Xi Jinping on Tuesday extended congratulations on the complete success of the Chang'e-6 mission that brought back the world's first samples collected from the moon's far side. It marks "another landmark achievement in China's endeavor to become a space and sci-tech power," Xi noted. 

In the congratulatory letter, Xi also stressed the hope to strengthen international exchange and cooperation in carrying out major aerospace engineering projects including deep-space explorations.

According to the China National Space Administration (CNSA), as planned, after the necessary ground processing work is completed, the recovered Chang'e-6 returner will be airlifted to Beijing, where the sample containers and payload will be extracted. The CNSA will hold a handover ceremony at an appropriate time to officially transfer the lunar samples to the ground application system. Subsequently, the samples will undergo storage, analysis and related research work.

After successfully completing the Chang'e-6 mission, the Queqiao-2 relay satellite will carry out scientific exploration missions at an appropriate time. It will use its onboard instruments, including an extreme ultraviolet camera, an arrayed neutral atom imager, and an Earth-Moon Very Long Baseline Interferometry (VLBI) experiment system, to collect scientific data from the moon and deep space, the CNSA said in a statement sent to the Global Times. 

Stargazers from all over the world have paid close attention to the 53 day-long round trip of Chang'e-6, and applauded Tuesday for the unprecedented feat of it retrieving precious lunar samples from the far side of the moon, while suggesting that these samples would not only help enhance the humanity's understanding of the Earth's natural satellite but also create new opportunities for international cooperation in space studies, including those with the US.

"I do think a successful conclusion to this very complex mission [Chang'e-6] will show that Chang'e-5 was not just a fluke, and that Chinese space engineers really have mastered the challenges of carrying out these very difficult missions far from Earth, it's a real step forward in the maturity of the Chinese space effort," Jonathan McDowell, an astronomer from the Harvard-Smithsonian Center for Astrophysics in the US, told the Global Times on Tuesday.

"The successful execution of the Chang'e-6 mission has achieved breakthroughs in key technologies such as retrograde lunar orbit design and control, rapid intelligent sampling on the lunar far side, and ascent from the lunar far side. These technological advancements lay a foundation for future deep space exploration missions," Kang Guohua, a professor of Aerospace Engineering at Nanjing University of Aeronautics and Astronautics, told the Global Times on Tuesday.

The mission not only sets a new record for China's lunar exploration program but also has a profound impact on the global aerospace field. Through the Chang'e-6 mission, China has demonstrated its leadership and influence in space exploration, Kang said noting that lunar soil from the far side of the moon holds immense value for scientific research and deep space exploration due to its uniqueness. 

Since no human probe has directly landed on and sampled from the far side, the soil from this area offers a distinct perspective. The South Pole-Aitken Basin is the oldest and deepest large impact basin on the moon, and samples from here can help scientists study the moon's origin and evolution more deeply, potentially providing critical clues about the formation and evolution of the solar system, he said.

Potential of intl collaboration in space

This year marks the 20th anniversary of China's lunar exploration program. China stands ready to continue working with like-minded international partners to explore humanity's common domain of the outer space, realize the shared dream of people around the world to discover more about the moon, and strive to advance the world's common endeavor of peacefully using the outer space, Chinese Foreign Ministry Spokesperson Mao Ning said on Tuesday, commenting on Chang'e-6's success.

The Chang'e-6 mission hosted four international payloads to the moon, including the European Space Agency (ESA)'s lunar surface ion composition analyzer, France's radon detection instrument, Italy's laser corner reflector, and a CubeSat from Pakistan, the CNSA revealed to the Global Times.

Pakistan's CubeSat, the country's inaugural lunar satellite, has sent back the first images it captured on May 10. It also achieved its goal of "successful separation and obtaining telemetry," marking the smooth completion of Pakistan's first-ever lunar project.

ESA's lunar surface ion composition analyzer, jointly developed with the National Space Science Center of the Chinese Academy of Sciences, successfully completed seven scientific detections after it started up on June 2, with the total detection time exceeding 3 hours, thus achieving the scheduled goal of detecting the lunar surface for at least 1 hour. This payload conducted negative ion detection on the lunar surface for the first time internationally, and the joint team is currently conducting scientific data analysis.

For the French payload, Philippe Baptiste, chairman of the French National Center for Space Studies, said it would still take some time to get all the data, but they are looking forward to it, as "the last time France was on the moon with an active instrument, it was in 1970," Baptiste was quoted as saying in a CGTN report.

The Chang'e-6 mission and its collection of precious samples from the far side of the moon will create more opportunities for cooperation between China and Western countries in space, according to space observers. And it is highly likely that NASA would again greenlight its researchers to access to these precious samples retrieved by the Chang'e-6 mission, however, the difficulties still lie in the US' domestic legal barriers, they said. 

McDowell said he would be happy to see sharing of data between China and the US. The US space observer pointed out however that "the political winds here in the US are still strongly against allowing any large-scale cooperation."

In a November 29 statement, NASA said it has certified its intent to the US Congress to "allow NASA-funded researchers to apply to the China National Space Administration for access to lunar samples returned to Earth on the Chang'e 5 mission." However, NASA made it clear that this allowance applies specifically to Chang'e 5 mission samples and "the normal prohibition on bilateral activity with (the) PRC (People's Republic of China) on NASA-funded projects remains in place."

Chinese Foreign Ministry spokesperson Mao Ning told the Global Times on June 7 at a regular press conference that China is always open toward space exchanges and cooperation with the US. There are, however, difficulties in China-US space cooperation at the moment, which are caused by US domestic legislation such as the Wolf Amendment that prevents normal exchanges and dialogue between Chinese and US space agencies, Mao said.

In a rarely seen friendly move, NASA Administrator Bill Nelson reportedly sent congratulations to China over the Chinese spacecraft's landing on the lunar surface earlier this month, saying he was impressed with its fourth successful moon landing, the Washington Post reported on US local time Monday. 

"I've been fairly pointed in my comments that we're in a space race with the Chinese, and that they are very good," he said in a recent interview with The Washington Post. "Especially in the last 10 years, they've had a lot of success. They usually say what they mean, and they execute on what they say."

However, the China space hawk continued its narrative of creating a new space race with China, by claiming that despite China's many achievements in space - which include an occupied space station in low Earth orbit and landing a rover on Mars in 2021 - the US remains on track to return astronauts to the lunar surface ahead of its chief rival, according to the report.  

In a key step toward that goal, NASA intends to fly four astronauts around the moon late next year, and then land people on the surface in late 2026 for the first time since the last of the Apollo missions, in 1972.

Despite competition between the US and China, the two countries will have to find a way to coexist on and around the moon, Nelson was quoted as saying.

NASA chief’s hawkish remarks another pathetic attempt, exposes US own hegemony and colonial ambitions

Chinese experts battered the latest round of attacks from NASA chief Bill Nelson, saying his smearing remarks against China's space development are yet another ridiculous and pathetic attempt to hype the "China threat" theory to get more funding, which only exposes the US' own hegemonic and colonial ambitions.

In an interview with POLITICO, Nelson said the race to the moon between the US and China is getting tighter and the next two years could determine who gains the upper hand.

He warned that Beijing could try to "dominate" the locations they step foot on the lunar surface or even try to "keep the US out," while citing the Nansha Islands as an "example" to prove his point. 

The remarks angered Chinese researchers and commentators who have repeatedly made clear that China's exploration of the moon is dedicated to the advancement of humanity. 

"Being a former astronaut himself, it is pathetic that he would play the trick of a thief crying 'stop thief,'" Song Zhongping, a space analyst and TV commentator, told the Global Times on Tuesday. 

It is an established fact written into the United Nations Outer Space Treaty and others that the moon does not belong to any country in the world, while the Nansha Islands are indisputably part of China's territory. Comparing these two shows that Nelson does not even understand international law or the Outer Space Treaty, Song noted.

Nelson's attempt in a way reflects the mentality that the US wants to colonize the moon and consolidate its own hegemony in space, analysts said, evident in the new space version of an "Enclosure Movement" of the Artemis program, which gathered "like-minded" partners such as Canada, Japan and Europe but excludes China and Russia. 

Nelson's remarks failed even to convince its own scholars. Victoria Samson, Washington director of the Secure World Foundation, said she is dubious about the "moon brawl," noting that China, like the US, is a party to the Outer Space Treaty, which bars nations from making territorial claims on any celestial body, including the moon, POLITICO reported.

It will be difficult for any nation to maintain a long-term human presence in deep space, she said, which makes the claims more unrealistic.

Nelson's remarks followed US congressional approval to fund NASA with $24.5 billion in fiscal 2023, about half a billion dollars less than US President Joe Biden had requested.

While still expressing "confidence" that the next moon mission could happen as planned to send a crew into the moon's orbit by 2024, he admitted that the agency is "under intense pressure" because it has been forced, as a cost-saving measure, to reuse all the avionics inside the Artemis I capsule for Artemis II.

Huang Zhicheng, a Chinese expert in aerospace science and technology, told the Global Times on Tuesday that NASA, with a lot on its plate including the operation of the International Space Station, the Artemis program and deep-space exploration projects, is hyping the "China threat" theory to get more money, as the just-concluded Space Launch System is already years behind schedule and billions of dollars over budget. 

There is still a huge gap in the budget and many problems to solve for the US' manned moon landing to succeed, Huang said. 

Specifically, Boeing that is undertaking the rocket launch tasks for the Artemis program has a chaotic management and it is hard to get the tasks done on time. For another thing, the moon lander being developed by SpaceX is yet to achieve its designated progress, and if the lander cannot be completed successfully this year, it may further delay the entire project, Huang noted. 

Publicly attacking China's space program has become routine for NASA in the past few months. In December, the NASA chief accused China of being "one of the very few nations" that would not be partners with the US and that it is being "very secretive" in terms of space programs. In September, Nelson accused China of lacking needed transparency over issues. In July, the NASA chief blatantly claimed that China is "trying to occupy the moon." In May, he said that China stole the US' space technology. 

"These accusations fired by NASA are unfounded and unjustified," Song said. "China has always had a cooperative and open attitude in the space sector."
