Science and techno world topic: Space
With the accuracy required for a
meeting with the space station Tiangon-1, China promptly sent into space on
June 16 three astronauts. The spacecraft Shenzhou-9 departed from Jiuquan
at 10:37 UTC, aboard a CZ-2F / G, Jing Haipeng, who had flown in the Shenzhou-7
(the last manned mission), Liu Wang, who debuts on this flight, and Liu Yang,
China's first woman astronaut.
The rocket was taken to the
drop zone, after months of preparation, on 9 June. By then, it was not yet
the exact release date, or even what would the spacecraft crew. The
station Tiangong-1 had fallen slightly in its orbit, so that the game should be
imminent. Finally, on Friday June 15th officially became known components
of the crew, and the date and exact time of launch.
As for the details of the
mission, they were also held in secret during the previous days. Only knew
that Chinese astronauts would join the Tiangong, maneuver and practiced by the
SZ-8 automatically, and would an undetermined number of days on board.
During the launch day the
authorities stated that in fact the SZ-9 would be coupled to the orbiting
complex, the first automatically. Then two of the astronauts would enter
the station, leaving the capsule in a case of emergency. If all went well,
would a few hours in the Tiangong, and then be cut off from its home port to
re-engage, this time manually. It is expected that after that astronauts
spend at least another four or five days on board, conducting experiments and
checking the operation of your new home. The mission should last about two
weeks total.

On 18 June, the SZ-8 was exposed
to the station and made a perfect approach automatically. The final
maneuver began some 50 km away, and lasted until 20. Then there were small
additional approaches, with brief stops to determine that all was going
well. The last was about 140 m away. Under the supervision of the
astronauts, the vehicle slowly approached and docked to the docking port of the
Tiangong-1 at 6:07 UTC. Thanks to the good alignment, the connection was
secured quickly, in less than 15 minutes. This resulted start checking the
safety of contact, pressurization, etc.
With everything ready, the entry
of two astronauts to the station was scheduled for about two hours after
docking. Although it is likely that their roles are changed during the mission,
there will be two crew in the Tiangong-1 and one in the Shenzhou-9, even at
night. After opening the hatch and proven good quality of the atmosphere
of the station Commander Jing Haipeng was the first to enter it, followed by
Wang Liu Both entered consecutively into at 09:05 UTC. Liu Yang should do
the same several hours later, but was allowed to look through the hatch shortly
thereafter and finally joined his teammates much earlier than expected, at
about 9:25 UTC. The entry of the astronauts, of course celebrated with
applause. Then astronauts reviewed the module and set off some of their
systems as the central computer and communications.
Within the complex, visitors will
debut some of the systems that are necessary for the long life of people in
orbit, such as water recycling, air purification, cleaning, etc.. As for
supplies, some 300 kg were transported aboard SZ-9 itself. The astronauts
also used medical equipment and installed on the Tiangong exercises to perform
physiological experiments.
Now here is a brief biographical
sketch of the three astronauts:
-Jing Haipeng: Born October 24, 1966
in China's Shanxi Province, has 45 years hence. He was selected in the
first group of astronauts China Space Agency (CNSA) in 1998. He is a pilot
with the rank of Lieutenant Colonel in the Air Force People's Liberation Army
(FAEPL) and member of People's Liberation Army (PLA) since June 1985. He
graduated from military school of pilots in 1990 and has 1,200 flying hours
under his belt. He was booking the flight of the Shenzhou-6 in October
2005 and flew into space on September 25, 2008 aboard the Shenzhou-7 mission
which lasted 2.85 days. It has become astronaut number 481.
-Liu Wang: Born in March 1969 in
China's Shanxi province, is 43. Second class is Pilot Air Force People's
Liberation Army (FAEPL) with an age of 6 years experience and 1,000 hours of
flight. Selected astronaut in 1998 (first group), he was the
youngest. She has performed in the space on this mission and has become
the contact person 524 in Earth orbit.
-Liu Yang: Born in the city of
Zhengzhou, capital of the northern province of Henan in October 1978, has 33
years hence. She is married with one son, and Lieutenant of China and Air
Force transport pilot with flying experience in four different aircraft types
of 1,680 hours. She Was selected in March 2010 within the second group of
Chinese astronauts. With this flight becomes the 56th woman to fly in
space and the person 525 in it.
