Testing of world's first non-steel launch tower
Monday's(03/11/03 )successful launch of China's recoverable science
experimental
satellite shows the reliability of the world's first satellite testing and
launch tower with a structure of cement reinforced by steel bars, space
experts said.
The tower, 91 meters high, replaces the commonly-used steel structure.
Located at Jiuquan Satellite Launch Center in Gansu Province, northwest
China, the tower looks like a high-rise building and is used for assembling,
testing and launching satellites and rockets, beside injecting propellants.
The building comprises of more than 40 testing workshops and closed rooms,
providing all-weather pre-launch testing in convenient and comfortable
conditions for engineers and technicians even it is windy, bitterly cold or
very hot outside.
Compared with the popular steel-structured launch tower at home and abroad,
the new tower is cost-effective.
Experts say the new launch tower represents the country's first versatile
launch facility capable of testing and launching different models of
satellites.
Previously, China had to build separate test, launch and control systems for
different models of satellite.
Located near the launch pad for China's manned spacecraft flight, the new
tower shares some of the ground facilities.

我非常喜欢在有风有雨的季节计划自己;
有风有雨后的季节晒着阳光我昏昏睡去;
睡去的我依然在甜梦中将曾有过的温习;
温习昨天前天等等的种种激情与过去。
