China is planning a three-stage program of unmanned lunar missions,with the aim of bringing back samples from the moon in around 2017,aerospace officials said on Monday.
"If there are no major problems,China's first unmanned satellite to the moon will be launched in 2007,"said Luan Enjie,chief commander of the country's lunar exploration program.
The lunar orbiter,Chang'e-1,is named after the Chinese legend of a young fairy who flies to the moon.The orbiter weighs more than 2 tons and ,is all goes according to plan,will fly for a year,Luan said.
In the first {phase} of the lunar probe program,the unmanned flyby mission will collect information of the moon's surface as well as studying its mineral content.
In the second phase,scientists plan to put a "lunar vehicle"on the moon to explore the lunar surface in around 2012.Through the wheelde robotic explorer,scientists hope to get to know the moon's environment and analyze the composition of lunar rocks.Luan said.
Another soft-lander will be launched in around 2017,with the mission of bringing back lunar samples.
To accomplish the missions,scientists will have to solve a chanin of problems about satellites,rockets and tracking systems.The lunar probe indicates China has taken an improtant steptowards exploration of deeper space.The moon will provide a platform on which to explor further into space .
China launchde its lunar exploraton program relatively late.The former Soviet Union launched Lunar 10,the world's first spacecraft to go into lunar orbit on April 4,1966,a few months before th US launched Lunar Orbiter 1.
