“China is expected to
complete its first exploration (探索) of the moon in 2010 and will found a moon base
just as we did on the North and South Poles,” Ouyang Ziyuan, head of China's
moon exploration program, promised during national science and technology week.
After
its first man in space, China
plans a space laboratory, a lunar orbiter to look for valuable elements and
minerals, robot landings on the moon and then the human touchdown.
The
price of space exploration is enormous. Russia
and the US,
the only two countries to have achieved manned flight, are struggling to keep
their new investment, the international space station.
But China, which has a long tradition in physics,
mathematics and engineering, finds its doctoral graduates welcomed in the US and Europe
for decades. And it has been able to learn from 40 years of pioneering
successes and mistakes by the USSR
and the USA.
Space
flight is a gamble and the stakes (赌注) are high. If successful, China could
become a member of the world's most exclusive club, set up a second home on the
moon and get a powerful hand at the strategic bargaining table.
Two
designers from the Shenzhou III project said that 12 astronauts now are
undergoing intensive training. One more unmanned space flight is planned before
the first manned launch.
Experts
say that the Shenzhou spacecraft already provides China with a space vehicle
capable of mounting(发起)a
lunar program. Chinese scientists have also predicted that Mars will be the
next target after the moon.
