China will
launch the Chang'e-3 lunar probe to the moon at 1:30am Monday from Xichang
Satellite Launch Center, the mission's launching headquarters said here
Saturday.
It will be
the first time for China to send a spacecraft to soft land on the surface of an
extraterrestrial body, where it will conduct surveys on the moon.
Facilities
at the launching site are in good condition and preparations are going well,
according to the headquarters.
The probe
will be launched to orbit aboard an enhanced Long March-3B carrier which is
more than three meters in diameter and 56.4 meters high.
The mission
will be the 25th launch of the Long March-3B, which is the most powerful launch
vehicle in the Long March fleet.
Engineers
have adopted technologies of high-precision guidance and control, multiple
narrow window launches, transmission system for remote sensing, and reduction
of the rocket's deadweight, said Cen Zheng, rocket system commander-in-chief of
the mission.
Chang'e-3
comprises a lander and a moon rover called Yutu (Jade Rabbit). The lunar probe
will land on the moon in mid-December if everything goes according to plan.
Tasks for
Yutu include surveying the moon's geological structure and surface substances,
while looking for natural resources.
So far,
only the United States and the former Soviet Union have soft-landed on the
moon.
After
entering lunar orbit, Chang'e-3 will go through six stages of deceleration to
descend from 15 km above to the lunar surface.
The
soft-landing processes of the US and former Soviet Union's unmanned spacecraft
had no capacity to hover or avoid obstacles. Chang'e-3, on the other hand, can
accurately survey landforms at the landing site and identify the safest spots
on which to land.
In order to
land quickly, the probe is equipped with high-precision, fast-response sensors
to analyze its motion and surroundings. The variable thrust engine (completely
designed and made by Chinese scientists) can generate up to 7,500 newtons of
thrust.
