BEIJING, Oct. 12 (Xinhuanet) -- Fei Junlong and Nie Haisheng, the two
astronauts undertaking China's second manned space mission, will live and work
in space for about 119 hours. How do they move,eat and sleep in the vessel?
Before the Shenzhou-6 was launched, two space medical specialists
prescribed detailed recipe for the two astronauts, including 50-odd varieties of
foodstuff. Fei and Nie will have three meals every day, with balanced nutrition
and adaptation to their respective tastes.
According to Chen Bin, head of the Space Nutrition and Foodstuff Research
Office under China Space Center, the two astronauts will have three meals every
day, 5 to 6 dishes for eachmeal. Foodstuff prepared for them total more than 40
Chen said the foodstuff can be classified into staple food and nonstaple food.
Rice will be the major staple food, with 140 grams of rice packed into a
vacuum bag to be warmed by a heater. Non-staple foods include beef cooked with
preserved orange peels, beef and cuttle balls and dehydrated vegetables such as
rape hearts cooked with mushrooms.
The astronauts have instant coffee, green tea, orange juice andeven creamy
soup to drink. Dehydrated, refrigerated fruits provided for them include
strawberry, apple, banana, peach and Hami melon.
SLEEP IN VARYING POSTURES
A sleeping bag has been arranged for the Shenzhou-6 spacecraft. It is hooked on the
wall of the vessel's orbit module. The astronauts will sleep by turns, one at
rest and the other on duty. Under the microgravity conditions, they may sleep
standing, sitting or lying. When they sleep, they should put their arms inside
the sleeping bag and tie their hands on their chests, so as not to touch
equipment switches accidentally.
It is reported that in microgravity environment, a sleeping person will
have a feeling that their arms and legs seem to separate from their trunks. An
astronaut from the former Soviet Union once took one of his arms left outside
his sleeping bag as aweird object floating toward him. He was scared in cold
sweat by the illusion.
ASTRONAUTIC SUIT: PERSONAL PROTECTION SYSTEM
Since no space walk is planned for the current manned space task, Fei and
Nie are equipped with only intra-capsule suits, which weigh more than 10 kg
each, said Li Tanqiu, director of the Astronautic Suit Research Office under the
China Space Center.
If accidental pressure loss occurs in the capsule, the astronautic-suit
rescue system will start to keep astronauts safe and sound in six hours, during
which the vessel will possibly realize an emergency return to the Earth, Li
At the place of heart on the astronautic suit, there is a round-shaped
device that can be screwed. It is used to readjust pressure, temperature and
humidity inside the suit. On the right side of the stomach position of the suit,
a thin tube serves for telecommunications; and on the left side, two pipes are
used for providing oxygen and discharging carbon dioxide.
According to Li Tanqiu, the outer layer of the suit is made of
high-intensity polyester fabric, allowing a five-square-centimetercloth to
resist a pulling force of 300 kg.
During their five-day space travel, Fei and Nie will take off the
astronautic suits to enter the orbiter from the re-entry module. In the
microgravity environment, they will take on and offthe suits in 10 minutes, Li
Tanqiu said. Enditem
