On June 5, the Shenzhou 14 manned spacecraft successfully launched
As of now, the Shenzhou 14 astronaut crew
has been in orbit for more than 70 days
What are they busy with in space station ?
According to the latest news released by China Manned Space Engineering Office
Shenzhou 14 astronaut crew
Recently, the Wentian Experimental Cabin has been completed in the Wentian Experimental Cabin
Environmental Control and Health Cabin
In orbit assembly equipment installation and testing work
Question day experiment cabin as a backup of Tianhe core cabin
In the daily operation of the space station
Cooperating with the core cabin to unified management and control

realizes the recycling of space station materials
Astronauts stay in the space station for a long time
The cost of transporting materials from the earth to space is too high
Therefore, it is necessary to realize the recycling of space station materials as much as possible
my country's space station regenerative environmental control and life insurance system
actually build a recyclable system similar to the earth's environment in sealing chamber
collects astronaut sweat and exhales water vapor
purifies it into drinking recycled water

via electrolytic oxygen-generating system
using circulating water to electrolyte oxygen-generating
The carbon dioxide
collected in the cabin reacts with hydrogen produced by electrolytic water , and water is obtained again, etc.
The regeneration environmental control and maintenance system of my country's space station
includes a total of 6 regeneration subsystems
, respectively, electrolytic oxygen-generating subsystem
carbon dioxide removal subsystem
trace harmful gas removal subsystem, urine treatment subsystem
water treatment subsystem and carbon dioxide reduction subsystem
It is reported that in the critical technology verification stage of the space station,
, the regeneration and maintenance system has realized the operation of the first 5 subsystems. The space station
, 2, oxygen , water and other resources regeneration and utilization
, so that the material closure of water resources exceeds 80%,

This carbon dioxide reduction atomic system
can further reuse the carbon dioxide generated by astronauts' breathing
and act on the space station
through the stable operation of the system
. About one kilogram of water can be recovered every day in the space station
. The material closure of water resources is increased to more than 90%
. That is to say, more than 90% of the drinking water for astronauts have been produced by regenerating water
. Only less than 10%
. The ground is supplied by cargo spacecraft
. Next, the "God Fourteen" crew
There is also a big mission
Next, Shenzhou 14 astronaut crew
There is also a big mission
is to wait for the arrival of Mengtian Experimental Cabin
At the beginning of this month, the second experimental module section of my country's space station
Mengtian Experimental Cabin has completed all the development work before leaving the factory
arrived at Wenchang Space Launch Site
and will be launched at an airport in October this year
After the launch is successful
my country's National Space Laboratory will be built
At the same time, now the "one" composed of Tianhe core module and Wentian Experimental Cabin
The word configuration
will also become the "T" character configuration
How to achieve this change? Click the video to learn about it ↓
First, after the Wentian Experimental Cabin is launched into orbit,
is connected to the forward interface of the Tianhe Core Cabin node cabin
At this time, the two cabin sections
form the "one" character configuration
in series, after the Mengtian Experimental Cabin is about one month before the launch of the Mengtian Experimental Cabin
, and the Wentian Experimental Cabin will be adjusted to the permanent parking port through the indexing robot arm
At this time, the Wentian Experimental Cabin and the Tianhe Core Cabin
form the "L" configuration combination html l1
is waiting for the arrival of Mengtian Experimental Cabin in orbit
0 Space Science and Technology Group Fifth Academy
Space Station System Supervisor Dispatch Wei Bangyou introduced
When the Mengtian Experimental Cabin was launched and docked
formed a "T" shape
Immediately after that Mengtian Experimental Cabin will also
transfer to the second quadrant
This truly realizes the "T" configuration of the space station
Shenzhou 14 astronaut
"space business trip" hard
I wish you a smooth work
successfully completed all tasks!
