2008年9月25日晚上9时10分，“神七”腾空而起，不到半个小时，北京航天飞控中心宣布“神七”发射成功。执行神舟七号载人航天飞行任务的航天员翟志刚、刘伯明、景海鹏出征前，向祖国和人民致以庄严的军礼。
“神舟七号”终于揭开了神秘的面纱，向世人露面，这是国人实力的又一次体现，也是中华民族实力的展示。
China's third manned spacecraft lifted off at 9:10 pm yesterday to fulfill
its most ambitious and risky mission: spacewalk.
Shenzhou VII, carrying astronauts Zhai Zhigang, Liu Boming and Jing
Haipeng, blasted off from the Jiuquan Satellite Launch Center in Gansu
province, into a clear sky.
As is the case with such missions, the first few moments were tense.
But then the ground control heard the voices of the astronauts. They
felt "physically sound", they said to the joy of the scientists
on the ground.
"The solar panel has unfolded, and we feel well," one of
them said. Remote-measuring signals showed all their physical indices,
such as blood pressure and heartbeat, were normal.
The astronauts will orbit the Earth for three days, 68 hours, to be
precise, and one of them will walk in space about 343 km above the Earth
on Saturday.
That will make China the third country to conduct extra-vehicular activity
(EVA) in space. The other two to have achieved that are the former Soviet
Union and the US.
The timing of the spacewalk could, however, be changed, depending on
how long it would take for the astronauts to adjust to all the factors.
EVAs are essential for China's long-term goal of building a space station
by 2020, and possibly launching a manned mission to the Moon.
Back at the Beijing Aerospace Control Center yesterday, hundreds of
scientists monitored and reported the spacecraft's status every few
seconds.
At 9:32 pm, Shenzhou VII entered its orbit. A minute later, Chang Wanquan,
chief commander of the center, announced that the lift-off had been
a complete success.
President Hu Jintao, who was present at the Jiuquan launch center,
congratulated the space scientists and the astronauts for the successful
lift-off.
"The successful launch marks the first victory of the Shenzhou
VII mission," Hu told scientists and other staff at the center.
"On behalf of the CPC Central Committee, the State Council and
the Central Military Commission, I congratulate all those who are part
of the mission."
A few hours before the launch, Hu saw off the three white-suited astronauts
on their way to the Long March II-F carrier rocket, which later took
them into space.
The spacewalk would be a milestone, he told them. "This will be
a major step forward for our country's aerospace technology."
"You can certainly fulfill this glorious and sacred task. The
motherland and its people await your triumphant return," he said.
The astronauts will land in central part of the Inner Mongolia autonomous
region in a re-entry module.
The astronauts entered the spacecraft at 6:28 pm yesterday, checked
the communication system with the ground control after reviewing the
operation manual of the spaceship.
The spaceship will change its orbit around 4 am today. And the astronauts
will start testing and putting on the EVA spacesuits, which could take
up to 15 hours.
China launched its first manned spaceship in October 2003, and followed
it up by sending Shenzhou VI two years later. But the Shenzhou VII astronauts
have a greater task in hand.
They have a wider choice of dishes too: nearly 80. One of them is spicy
kung-pao chicken cooked following a "new method", Chen Bin,
the mission's chief nutritionist, told Xinhua.
They will also take traditional Chinese medicine made with more than
10 herbs to treat space motion sickness.
Engineers overseeing the flight have, however, warned of risks. Zhang
Jianqi, one of the chief engineers, told Xinhua that keeping the three
men in the craft and sending one outside the capsule would be a "big
test".
"This is a big technological leap," he said. "The risks
are quite high. Sending up three astronauts is a jump both in quantity
and quality."
Space motion sickness can cause dizziness, vomiting and nausea. A depressed
astronaut could feel severe pain in the joints, have breathing difficulty
or could even lose consciousness.
"Some of these can be life-threatening," said Li Yongzhi,
director of medical department of the China Astronaut Research and Training
Center.
