The Chang’e I Lunar Probe
The Chang’e I lunar probe is China’s first lunar probe
successfully launched on LM-3A rocket on schedule at 6:05 p. l time ( UTC +8) from the Xichang Launch Center
on October 24
2007.
The “Orbiting ( Chang’e I )
phase of the program has four major goals:
“嫦娥一号”的主要任务有：
Drawing ”pictures“ of the Moon and obtaining three-dimensional images of the lunar surface. Dividing the basic landforms and structures of the lunar surface and initially making outline graphs of lunar geology and structures
so as to provide a reference and basis for later soft landings
The orbit of Chang’e I around the Moon will provide plete coverage
including areas near the North and South Poles not covered by previous missions. Probing useful elements on the Moon surface and analyzing the elements and materials
primarily making maps of the distribution of various elements on the Moon’s surface. China hopes to expand the number of the useful elements t0 14 previously probed by the NASA’s Lunar Prospector
and will conduct an overall prospect evaluation on some useful resources on the Moon’s surface. Probing the features of lunar soil and evaluating its depth
as well as the amount of helium-3 ( He)ing the space environment beeen the Moon and the Earth
recording data on the primitive solar wind and studying the impact of solar activity on the Earth and the Moon.
The first picture of the Moon was relayed on November 26
2007. The mission is scheduled to continue for a November 12
2008
a map of whole lunarsurface taken by Chang’e I was shown to the public.
The launch of the l.4 billion Yuan ( $ 187 million) Chang’e I
named after the Chinese goddess of the moon
is considered to be the first step in China’s three-stage moon exploration campaign
with the second step being the delivery of a moon rover
and the third that of a recovery research vehicle to collect soil ultimate aim of the Chinese project is to put a man on the moon by 2020.
