BY ONE well-known (if fictitious) criterion, the purpose of a space
programme is to boldly go where no man has gone before. China, however, has
a different plan: to boldly go back where men have already been.
Specifically, with the release on December 29th of an official space-policy
paper, it has said it wants to send people to the moon.
The last earthling to leave a footprint on the lunar surface, Eugene Cernan,
did so in 1972. He was (and is) American. According to the new paper—the
first of its kind since 2006—the next print in the regolith is likely to be
Chinese. The country’s experts have long discussed the possibility of such
a mission, but this is the first official acknowledgment of a decision to
proceed.
The document is, however, more than a mere claim to vainglory. It outlines a
programme that will, if fully implemented, make China a space power equal
to America and Russia.
One goal for the next five years is to improve China’s Long March rockets,
the workhorses that launch its satellites. The Long March-5, in particular,
is intended to be able to lift 25 tonnes into low Earth orbit. (Perhaps
significantly, this is 600kg more than America’s space shuttles could
manage.) Another part of the plan is to upgrade the country’s satellite
networks. A series of high-resolution Earth-observation satellites is to be
launched over the next five years, and by 2020 the Beidou global-positioning
and navigation system, a set of 35 satellites equivalent to America’s
Global Positioning System, should be in place. That will provide a boost to
the command and control capabilities of China’s armed forces. Progress was
also promised on Tiangong-1, China’s newly launched space station. And
there will be unmanned flights to the moon, including sample-return missions
, and manned orbital flights to test life-support systems.
The one place China does seem unlikely to be going, ironically, is the so-
called International Space Station. This is an American-led venture and the
United States seems reluctant to extend the term “International” to
include China. That is partly because of paranoia about sharing technology
with China, according to John Pike, the head of GlobalSecurity.org, an
American think-tank. But it is also possible to detect a sense of pique that
China is willing to do things (like going to the moon, and even just having
a space programme that can put humans into orbit) which America, at the
moment, can’t.
Ultimately, manned space flight is futile. All the scientifically and
practically important stuff can be done by robots. Nevertheless, symbols
count. If the next man (or woman) on the moon is Chinese, many people will
see it as a sign that America has been surpassed again. | S*****s

发帖数: 1233 | 4 这篇太过了，底下的comments没有一个人同意这傻逼记者的:
It may be true that economically, manned space flight struggles to deliver
the returns that a project accountant (or an Economist correspondent) has
been trained to look for, or which Newt Gingrich supposes may be available
by say shipping moon rocks back to earth to be used in cement.
Nevertheless, as other readers have noted, only manned space flight is
important ultimately. Would this Economist correspondent prefer to watch
Animal documentaries than go on safari to Africa...or look at photos of
Paris than explore that city in person? If so, my guess would be that his/
her friends/spouse left for more exciting company years ago.
If the first moon landing programme was a one-off political endeavour to
send a message to the Soviet Union that free market capitalism could deliver
superior results faster, the present second phase of space exploration
should be a sustainable expansion of man's interplanetary capabilities.
First the moon then to Mars and beyond. A red planet for a red country! At
least some part of humanity retains the ambition to push human boundaries
beyond the limits posed by an economic return. If that had not been the case
in history we would still be sitting in our caves.
