Red Star in
Orbit: China Learns from NASA's Mistakes
Martin Sieff
Can
China, with only a fraction of the Gross National
Product of the United States, actually beat out America
in manned space exploration over the next decade and
more? The answer is: Yes. Easily.
China's
space program shows every sign of using reliable, mature
and inexpensive technology, rather than
bankrupting itself on showy but dangerous and vastly
over-ambitious technology that the U.S. manned space
program has relied upon for more than two decades with
the Space Shuttle program.
The
Space Shuttle was supposed to make space travel routine,
cheap and safe. It did none of those things. The Space
Shuttle program originally dreamed of launching over a
dozen space flights annually. However, in reality, the
program has only averaged roughly five flights per year,
even before the tragic disintegration of the
Columbia
on reentry at the beginning of this year. Plus, far from
being cheap, they always cost a billion dollars a
flight.
Far
from being safe, they have so far immolated 14
astronauts in two catastrophic disasters, the explosion
of the
Columbia
in 2003 and of the Challenger in 1986. That is more than
twice the total number of recorded dead cosmonauts from
the Soviet/Russian space program since its inception 42
years ago.
Also,
the space shuttle program cost so much money that it has
leached resources away from developing any realistic
alternatives. Today, ironically, the United States has
less capabilities for manned space exploration than it
did 31 years ago at the time of the last manned Moon
mission, Apollo 18.
By
contrast, China's space program is based on the older,
vastly safer, more reliable and infinitely cheaper
technology that the United States developed in the 1960s
and the Soviet space program continued to use for its
very limited but scientifically immensely important
long-duration space station missions of the 1980s and
1990s.
China's
Shenzhou class capsules have been developed slowly,
thoroughly and conservatively. As UPI science
correspondent Frank Seitzen wrote on July 8, "Shenzhou
began development in 1992 and so far has been launched
successfully four times, the first of which was in
November 1999. Each year,
China
has flown a new more capable, unpiloted variant of the
ship." The Shenzhou spacecraft, like the evolution of
the Apollo moon-ships which grew out of the previous
tried-and-tested Mercury and Gemini capsules, reflects
an organic, orderly evolution from the earlier, more
primitive designs it was based upon. "Slightly larger
than its Russian counterpart [Soyuz], Shenzhou is
constructed of more advanced materials and lighter
component materials than the 30-year-old Soyuz." It also
"has larger and more extensive solar panels than Soyuz."
And in
the crucial area of astronaut - or as the Chinese would
put it,
taikonaut
- safety, Shenzhou is actually far more advanced than
the U.S. Space Shuttle program in protecting the lives
of its crew. As Seitzen reported, the Long March 2F
booster rocket "flies with an abort system that can
blast the manned capsule free of the booster in the
event of a launching mishap." That kind of equipment
could have saved the lives of the seven Challenger
astronauts, had it been installed on the Shuttle program
in the 1980s.
The
Chinese have also learned from their Russian mentors in
giving priority to producing a stable, reliable and cost
effective "big dumb booster." Their Long March 2E cargo
booster, which has been amended to carry the manned
Shenzhou spacecraft in its 2F class, is conceptually
very similar to the Soviet/Russian Proton booster. It
is not a spectacular super-rocket that blasts its
payload all the way to the Moon as the colossal Saturn
Vs did 34 years ago. But then, even the United States
can no longer build any Saturn Vs. Too many of the vital
plans have simply been lost through simple bureaucratic
incompetence.
What
the Long March 2 provides is a solid, unspectacular work
horse than can be cost-effectively produced in
sufficiently large quantities to put crews into space on
a regular basis and acquire the kind of crucial program
experience and capability that the United States did
with its 1965-66 Gemini program.
A
cautious but highly competent and ever-developing
"tortoise beats hare" design and testing philosophy has
guided China's space program over the past decade. This
indicates that continued incremental but ever more
significant design evolution will lead to vastly
improved performance and payload capabilities in the
years to come.
Still,
conventional wisdom maintains that China will find it a
long road from putting a single taikonaut into
orbit to fulfilling its dreams of trumping the United
States and Russia with impressive orbiting space
stations and an eventual moon base. But conventional
wisdom may very well be wrong.
