A Long March 2F
successfully launched Shenzhou 3 from Jiuquan Satellite Launch
Center at 1415 UTC (6:15 a.m. PST) on March 25. Chinese President
Jiang Zemin attended the launch. A satellite is
included as an auxiliary payload on this flight, though no details
on the satellite have been made available.
There will be a
human dummy on board as part of the test of the life protection
system. Other tests will include checking the safety of the
reentry system as well as conducting experiments on board and
sensing the space environment. After the Descent Module separates
from the Orbital Module for reentry, the Orbital Module will
continue operation in orbit for about half a year. This mission
also includes an auxiliary satellite. News reports do not indicate
when the Descent Module is expected to return.
Instead of using
monkeys China is using dummies rigged up with sensors.
"Unlike decades ago when many technical difficulties existed,
making a dummy is now simpler. We could, say, measure simulated
blood pressure using a dummy on a mission. If a monkey is launched
into space, unless it is tightly secured and made immobile, the
monkey could touch anything on board and cause troubles.
"Speaking from another perspective, we want to guarantee the
safety of the yuhangyuans much as with the animals. Otherwise
animal protection groups would protest," said Zhuang Fenggan,
Chairman of Science and Technology Committee of China Aerospace
Science and Technology Corporation (CASC).
Mission designers
had hoped to improve the interior installation of the spacecraft
on this mission, but problems appeared after the changes were
implemented. This forced the design team to revert back to the
previous interior set-up and delayed this year’s mission.
The long delay of
the Shenzhou 3 mission has pushed back the timeline of the first
manned flight. The Japanese newspaper Yomiuri Shimbun reported, a
year ago, senior Chinese space officials saying that China could
launch the first manned mission late this year. Hu Shixiang,
Deputy Minister of the General Armament Department of the People's
Liberation Army (PLA), recently acknowledged that that timeline
has became unrealistic. Hu said that depending on the outcome of
additional unmanned test flights of Shenzhou, the first manned
mission could take place as early as next year. If testing
progresses smoothly, there may be another unmanned test flight
this year.
Among those who
accompanied Chinese President Jiang Zemin at the Jiuquan Satellite
Launch Center included Wu Bangguo, member of the Political Bureau
of the CCP Central Committee and vice-premier, Zeng Qinghong,
alternate member of the Political Bureau and member of the
Secretariat of the CCP Central Committee, Yu Yongbo, member of the
Central Military Commission and director of the PLA General
Political Department, and Cao Gangchuan, member of the Central
Military Commission and director of the PLA General Armament
Department.
This is the third
flight of the CZ-2F launch vehicle, which was designed and
developed at the Chinese Academy of Launch Vehicle Technology (CALT).
The first unmanned test flight of the Shenzhou program was in
November 1999. The Shenzhou 1 orbited the earth 14 times in a
12-hour mission aimed mainly at testing launch and re-entry
capabilities. The Shenzhou 2 was launched on January 9, 2001,
orbiting the earth 108 times while testing life support systems.
