中国神舟十四号发射升空的英文总结
China launched the Shenzhou-14 crewed spaceship at 10:44 June
5,2022,Beijing Time,sending three astronauts to its space station Tiangong.
After entering its designated orbit,the spaceship conducted a fast rendezvous
and docking with the space station 8:,astronauts Chen
Dong,Liu Yang and Cai Xuzhe entered the Tianhe core module of the space station
and began their six-month stay in orbit.
This is the 23rd spaceflight mission since the approval and launch of China’s
manned space program and the third crewed mission for China’s space station
project.
During the Shenzhou-14 crewed mission,the three astronauts are expected to
complete the construction of the country’s space station,which mainly consists of
the Tianhe core module and two lab modules named Mengtian and Wentian,and
finally establish the country’snational space laboratory.
In the following six months during their stay in the space station,the
Shenzhou-14 crew will witness the Wentian and Mengtian lab modules,Tianzhou-5
cargo craft,and Shenzhou-15 manned spaceship dock with the Tianhe core
module.
During their stay in orbit,the crew members will carry out in-orbit verification
of small and big mechanical arms,verification of the role of an airlock cabin in the
Wentian lab module in supporting extravehicular activities,installation of
extravehicular payloads and other space station-construction related work.
Meanwhile,the crew will continue public benefit activities including the
“Tiangong Class”live science lecture,and conduct in-orbit health monitoring and
examination,protective exercises,in-orbit training and drills,as well as a lot of other
activities such as station platform inspections and tests,equipment maintenance
and verification,and station and material management.
Following the launch of the Shenzhou-14 crewed mission,China will launch the
Wentian and Mengtian lab modules to create a larger platform for scientific
experiments and tests in space.
As China’s national space laboratory,the Tiangong space station will be able
to accommodate 25 experiment cabinets for scientific exploration,according to Lin
Xiqiang,spokesperson for China’s manned space program anddeputy director of
the China Manned Space Agency(CMSA).
Each of the 25 experiment cabinets will be able to function as a small-sized lab
where space science experiments for a single subject or interdisciplinary research
can be carried out,with their overall capacity reaching an advanced international
level,Lin said.
The Wentian lab module will mainly be used for space life sciences
will be equipped with experiment cabinets for experiments on life and
ecology,biotechnology,and varying-gravity science research,as well as experiments
and research in closed will also support research into the response
mechanisms of various kinds of plants,animals,microorganisms,
growth,development,heredity,and senescence in space.
The Mengtian lab module is designed to serve microgravity
ed with experiment cabinets for the study of physics of
fluids,material science,combustion science,fundamental physics,space technology
experiments and other disciplines,the lab module will be able to support research
into the essential laws of relevant matter and frontier research including those in
ultracold atomic physics.
China will establish the world’s firstcold atomic clocks in space consisting of a
hydrogen clock,a rubidium clock and an optical clock in its space station on the
basis of the cold atomic clock that once worked on board China’s“retired”
Tiangong-2 space lab.
The cold atomic clocks will form the most precise time and frequency system
in space,which will serve frontier scientific research including gravitational redshift
research and measurement of fine structure constants.
The country will also launch the Xuntian space telescope into the orbit of the
space station to carry out wide-area survey observations.
Upon the completion of the in-orbit construction of the space station,China’s
manned space program will enter a stage of application and development that will
span more than 10 years.
According to China’s initial plan for the new stage,the country will launch two
manned spaceships and two cargo spacecraft every year,and astronauts will stay in
orbit for a long term to carry out space scientific and technological experiments
and maintain the space station.
The country also plans to develop reusable new-generation manned carrier
rockets and spacecraft that can carry seven astronauts.
