Life conditions in Shenzhou-5 "about the same as on earth": expert
( 2003-10-15 19:03) (Xinhua)
Conditions for life in Shenzhou-5 are about the same as on earth, a senior
expert told Xinhua Wednesday.
The spacecraft comprises three main parts: the propulsion module, orbital
module and re-entry module. The orbital and re- entry modules, both airtight,
are where the astronaut lives and works during his space journey.
While in space, however, he works, eats and sleeps in the orbital module,
according to Su Shuangning, a chief designer for the astronaut system under
China's space flight program. "The onboard life support system creates an
intra-module environment about the same as on earth," the expert said.
Elaborating, he said that the astronaut system is fitted with sub-systems for
air pressure, ventilation, sterilization, temperature and humidity. These
ensure normal temperature, moisture and air pressure, including the pressure
of oxygen and carbon dioxide, inside the two modules.
Shenzhou-5 operates primarily on preset programming, meaning that the
astronaut plays a supplementary role in monitoring the flight and in
controlling and running the spaceship in the course of the flight. His task
is to observe and record the conditions of the orbiting spaceship for
reference of the ground control center.
The astronaut relies mainly on the control center for information. At regular
intervals, he reports to the center the conditions of the on-board systems
and the flight. He also informs the center of his own conditions - whether he
feels well, whether he sleeps well, whether his appetite is good, as well as
his urination and bowel movement.
"In case a mal-function occurs when the spacecraft changes its orbit, the
astronaut will step in to control the flight manually," Su said.
While in the space vehicle, the astronaut has three meals a day - breakfast,
lunch and supper, the recipes including canned food, dehydrated rice and
fruit, which can be re-hydrated and heated. The so-called "space food," food
consumed by astronauts in space, produces limited residue, but is rich in
calories and highly digestible. Chinese food is available, the likes of rice
cooked with nuts, dates and other delicacies, spicy and sour shredded meat
and diced chicken.
The astronaut does not have a bed to sleep on. He has a sleeping bag hung on
the interior wall of the spacecraft, and sleeps in it when he is free from
the duty of reporting to the ground control center. According to Hu, he will
sleep twice during the space journey, for three or four hours at a time.
While flying, the astronaut also writes the flight log, talks with the ground
center and with his doctors. "If he has time to spare," the expert said, "he
may take photos and videos of the outer space."

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。
