China exchanged data with NASA on mission to the other side of the moon
China exchanged data with NASA on its recent mission to land a spacecraft on the other side of the moon, the Chinese space agency said.
It is reportedly the first such collaboration since a US law banned joint space projects with China that do not have prior approval from Congress.
Wu Yanhua, deputy director of the space agency, said NASA had shared information about its lunar satellite in the hope of following the landing of the Chang 4-spacecraft, making China earlier this month the first country landed on the other side of the moon.
China, in turn, shared the time and coordinates of Chang's planned landing 4, Mr. Wu told reporters during a briefing on the lunar mission.
He added that while the Nasa satellite did not exactly reach the moment of landing, it took pictures of the area afterwards.

The state-run China Daily said it was the first form of such cooperation since the US law of 2011 was passed.
The lunar mission of Chang & # 39; e 4 and his robber, Jade Rabbit 2, was a triumph for China's growing space program, which quickly caught up with Russia and the US.
President Xi Jinping has placed space exploration under the national development priorities of the country and the distant mission offered China a chance to do something that had not been done before by another country.
The other side of the moon – the side that is off the earth – posed a challenge for scientists because it is out of the reach of radio signals.
China set up a relay satellite in May to receive communication from Chang & # 39; e 4.
"In the past we were always in a hurry to overtake the advanced global standards" in space, said Wu Weiren, the chief designer of the Chinese moon exploration project.
"There were many things to catch up and fewer things in which we could outdo others," he said.
"With the probe on the other side of the moon this time, Chinese people have done very well."
Officials at the briefing refused to give specific figures on the cost of the space program.

Wu Yanhua said that the Chang & # 39; e 4 was originally built as a "spare product" for Chang & # 39; e 3.
He said that the expenses needed to restore it for his new target were comparable to repairing a short section of the metro line.
Around the end of this year, China plans to market Chang & # 39; e 5, ie collecting and recalling samples from the nearest side of the moon, the first time since 1976.
Scientists are still investigating whether they should send Chinese astronauts, Wu said.
The country has also said that it will welcome scientists and astronauts from all over the world to use the space station to be completed by 2022.
