Red Star in Orbit: China
Learns from NASA's Mistakes
October 15, 2003

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.
