China says it exchanged data with NASA on far side landing
BEIJING (AP) — China exchanged data with NASA on its recent mission to land a Chinese spacecraft on the far side of the moon, the Chinese space agency said Monday, in what was reportedly the first such collaboration since an American law banned joint space projects with China that do not have prior congressional approval.
The space agency's deputy director, Wu Yanhua, said NASA shared information about its lunar orbiter satellite in hopes of monitoring the landing of the Chang'e 4 spacecraft, which made China the first country to land on the far side of the moon earlier this month.
China in turn shared the time and coordinates of Chang'e 4's scheduled landing, Wu told reporters during a briefing on the lunar mission. He added that while NASA's satellite did not catch the precise moment of landing, it took photographs of the area afterward.
The state-run China Daily said that was the first such form of cooperation since the 2011 U.S. law was enacted.
NASA has not published any statements on the collaboration and could not immediately be reached for comment.
The lunar mission by Chang'e 4 and its rover, Jade Rabbit 2, was a triumph for China's growing space program, which has been rapidly catching up with those of Russia and the U.S. President has placed space exploration among the country's national development priorities and the far side mission offered a chance for China to do something not done before by any other country.
The far side of the moon — the side which faces away from Earth — posed a challenge for scientists because it is beyond radio signals' reach. China set up a relay satellite in May to receive communication from Chang'e 4.
"In the past, we were always rushing to catch up to the advanced global standards"in space, said Wu Weiren, the chief designer of China's lunar exploration project.
"There were many things to catch up on, and fewer things in which we could surpass others," he said. "With the probe of the far side of the moon this time, Chinese people have done very well."
Officials at the briefing declined to give specific figures on the costs of the space program.
Wu Yanhua said the Chang'e 4 was originally built as a "backup product" for Chang'e 3. He said the spending needed to refit it for its new objective was akin to repairing a short section of subway line.
Around the end of this year, China plans to launch Chang'e 5, which is to collect and bring back samples from the near side of the moon, the first time that has been done since 1976. Scientists are still researching whether to send Chinese astronauts, Wu said.

It's nice to see cooperation in space ventures. Now, if only we could cooperate with each other on earth.

I'm still amazed at the number of people who think the far side of the moon is constantly dark and never gets sunlight.

Another reason to have more faith in science is the fact that scientists can cooperate in spite of their differences.

USA and Russian space authorities always cooperated even during the Cold War.

Doesn't matter. They have exceed expectations. When is the last time, US land on the moon? Why couldn't we send in more probe to every surface of the moon and Mars for possible resources and proof of other factors. The Chinese have try to test planting a seed with insects to try to provide oxygen with very little sun lights. Let see how that progress.

The best news so far. It means the two economic, scientific and military powers are working together to bring peace to the world. I hope Russia will join them soon.

US has been refusing to work with China on any space program--- Chinese exclusion policy of NASA

China is showing the good will and leadership in the world. And the new era of global leadership where China will soon become a good example as good role model in the world. Congrats China.

If you think about it, the US received most its tech from the Germans. China simply proved to be better at one upping in the grand scheme of things

NASA can make a deal with China, but our own government can't make a deal with itself. Outstanding display of dysfunction.

Still not the same as landing a man on the moon.

My guess is that china would not have been able to land on the moon without NASA's help, and definitely would not have any kind of space program if china had not stolen all the technology from the US. china has not accomplished hardly anything on their own.

all the relevant technology china is using to land on the far side of the moon had been invented by others ,they are just copying.They should be greatful to those who invented them

I wonder why we haven't landed a man back on the moon since 1969. Was it really just a big hoax?

If US can put down the hegemonic arrogance and peacefully compete with China, the whole world would be benefited.

If the U.S. and the Soviet Union could cooperate in space during the Cold War, then the U.S. and China can cooperate now.

People say that the US has already sent men to the moon, which means that China is 50 years behind. NO, no, no. The US has NO technology to go to the moon.Even NASA said so. The big Saturn V rocket technology was LOST (yes, LOST by mistake). All the other technology, such as shielding, space navigation, knowledge of space hazards, are basically lost because the older generation of scientist have all been retired.

Good to see working together....
