One leading engineer designing China's first manned spaceship said here
Wednesday that Shenzhou-5 was equipped with 52 engines, which ensures its
precise move and orbit keeping.
Qin Wenbo, vice chief engineer of the spaceship, said that designing the
spaceship's propulsion systems was one of the most demanding tasks.
"It's very difficult to decide when we should ignite the engines and how long
they should work," said Qin, who is also vice chief engineer of Shanghai
Aerospace Institute.
A total of 28 engines were installed in the propulsion module, eight in the
re-entry module and the rest in the orbit module, Qin said.
"After repeated tests since China launched its first spaceship, Shenzhou,"
Qin said, "it has been proved that our propulsion systems are reliable."
Engineers have also installed two cameras in the re-entry module, which is
expected to transmit audio and video signals to the ground command and
control center.
Qin said that the headquarters could not only talk to the astronaut, but also
monitor physical data of the nation's first spaceman.

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。
