China has successfully test-fired its first four-stage solid-fuel launch
vehicle capable of putting small satellites into space, a spokesperson for
the developer said on Wednesday.

The spokesperson for China Aerospace Science & Industry Corp (CASIC) said
that the successful test on Sept. 16 at north China's Taiyuan Satellite
Launch Center makes China the third country in the world capable of
developing such rockets after the United States and Russia.

The newly-developed rocket is capable of putting up to 100-kg satellites into
orbit around the earth for resources exploration, environmental monitoring
and survey, scientific experiments and other purposes, said the spokesperson.

"Compared with powerful launch vehicles that use liquid fuel, the solid-fuel
launch vehicle, popularly known as Pioneer I, requires much less preparation
time to launch, and is much easier to operate."

It takes only 12 hours or even less to get ready to launch a satellite using
the Pioneer I rocket, while about three months' time is required for a
liquid-fuel launch vehicle, including shipping the vehicle, installation and
testing, and filling it with liquid fuel, said the spokesperson.

The Pioneer I rocket can be launched from a mobile pad, and it is easier to
make its traveling speed much faster, he added.

Xia Guohong, general manager of CASIC, said that Chinese rocket experts at
the company will conscientiously sum up the useful experience gained from the
experiment, and strive to put a small satellite into space at an early date
using the rocket.
