China rocket blasts off for far side of Moon

BBC Online :
China has launched a probe to collect samples from the far side of the Moon, in what is being billed a world first.
An unmanned rocket carrying the Chang’e-6 probe blasted off from the Wenchang Space Launch Center at about 17:27 local time (10:27 BST).
The 53-day mission aims to bring around two kilograms of lunar samples to Earth for analysis.
It will try to re-launch from the side of the moon facing away from Earth.
This is described as the dark side of the Moon because it is invisible from Earth, not because it does not catch the sun’s rays.
It has a thicker, older crust with more craters, which are less covered by ancient lava flows than the near side.
This may make it more possible to collect material that helps shed light on how the Moon was formed, scientists hope.
Ge Ping, vice director of China’s Lunar Exploration and Space Engineering Center, told reporters ahead of the launch: “Chang’e-6 will collect samples from the far side of the Moon for the first time.”
The probe was named after the Moon goddess and one of the most popular figures in Chinese mythology.
It is expected to land in the South Pole-Aitken Basin, which is some 2,500km (1,553 miles) wide and up to 8km (5 miles) deep.
It then aims to collect lunar soil and rocks, and conduct experiments.
The launch marks the first of three high-wire unmanned missions to the moon planned by China this decade.
Chang’e-7 will search the lunar south pole for water, and Chang’e-8 will attempt to establish the technical feasibility of building a planned base, known as the International Lunar Research Station.
