China launches science satellite
China on Monday launched a recoverable science experimental satellite into a
preset orbit, atop a Long March 2 D carrier rocket from a newly-built launch
tower at Jiuquan Satellite Launch Center in Northwest China's Gansu Province.
Space officials said the China-made satellite was launched at 3:20 p.m.. The
officials said the satellite would remain in orbit for 18 days before
returning to Earth.
Reports from Xi'an Satellite Monitor and Control Center say the satellite is
orbiting as scheduled and its instruments are functioning normally.
It is the 18th recoverable satellite developed by China, and is technically
much more advanced than the previous ones in terms of its performance.
The satellite is mainly for scientific research, land surveying, mapping and
other scientific experiments, said space experts.
The data China gathered from the satellite will help promote the country's
scientific and technological, economic and social development.
With a lift-off mass of 251 tons, the launch vehicle, 40.6 meters in length,
was developed by the Shanghai Academy of Space Technology with China
Aerospace Science and Technology Corp.
The launch is the 73rd by the country's Long March carrier rockets since
1970, and the 31st consecutive successful launch since October 1996.
Space experts said the success rate of Long March rockets was 91 percent.
Monday's launch came less than a month after China's first manned space
flight on Oct. 15 and 16, and the Oct. 21 launch of an earth resources
satellite developed in cooperation with Brazil and a smaller satellite.
Space experts said the number of launches in such short period is
unprecedented in the country's history, indicating the country's progress in
launch capability and development of launch vehicle and spacecraft.

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。
