China launched a relay satellite early on Monday designed to establish a communication link between earth and a planned lunar probe that will explore the dark side of the moon, the official Xinhua news agency said.
Citing the China National Space Administration, Xinhua said the satellite was launched at 5:28 a.m. (21:28 GMT Sunday) on a Long March-4C rocket from the Xichang launch centre in the southwest of the country.
"The launch is a key step for China to realise its goal of being the first country to send a probe to soft-land on and rove the far side of the moon," Xinhua quoted Zhang Lihua, manager of the relay satellite project, as saying.
It said the satellite, known as Queqiao, or Magpie Bridge, will settle in an orbit about 455,000 km (282,555 miles) from earth and will be the world's first communication satellite operating there.
However, while China has insisted its ambitions are purely peaceful, the U.S. Defense Department has accused it of pursuing activities aimed at preventing other nations from using space-based assets during a crisis.
