The trio on a business trip to space began to pack their bags and prepare to go home.

The space travel trio began to pack their bags and prepare to go home. Before going home, they need to restore the cabin environment as much as possible, such as fitness equipment, experimental supplies and maintenance spare parts, which need to be repackaged and put back in the designated location. The trio on a business trip in space began to pack their bags and prepare to go home.

Three space travelers began to pack their bags and prepare to go home. The three astronauts of Shenzhou XIII have been working and living in the space station for more than five months. According to the plan, they will work and live in orbit for about 180 days, and now they have entered the countdown to "going home".

According to CCTV news, at present, the trio on business trip in space began to pack their bags, strengthen their physical fitness and prepare to go home. Many netizens welcomed home after seeing this scene, paid tribute to the space hero, and looked forward to the hero's triumphant return, smooth and safe!

According to the previous report of China News Network, at the press conference of "Blue Book of China Aerospace Science and Technology Activities (202 1)" held on February 9, it was officially introduced that the Shenzhou-13 manned spacecraft was scheduled to carry out the return mission in mid-April, and the quick return scheme would be adopted for the first time.

At 0: 23 Beijing time (202 1, 16), the Long March II F- 13 carrier rocket carrying the Shenzhou XIII manned spacecraft blasted off at Jiuquan Satellite Launch Center. Shenzhou XIII manned spacecraft successfully separated from the rocket and entered the scheduled orbit, and sent three astronauts, Zhai Zhigang, Wang Yaping and Ye Guangfu, into space successfully. The pilot was in good condition and the launch was a complete success.

This is the second1mission since the implementation of China's manned spaceflight project, and it is also the second manned mission in the construction stage of the space station.

Three space travelers began to pack their bags and prepare to go home. The three astronauts of Shenzhou XIII spacecraft have been working and living in the space station for more than five months. According to the plan, they will work and live in orbit for about 180 days, and now they have entered the countdown to "going home". Starting from this week, they have entered the preparatory stage for their return. Let's look forward to their early and successful return!

Tidy up the "room"

The astronauts put all relevant equipment in place.

After the astronauts entered the core cabin of the space station, they unloaded a large number of daily necessities and experimental equipment from the cargo ship and arranged a "small home" in the sky. Before going home, they need to restore the cabin environment as much as possible, such as fitness equipment, experimental supplies, maintenance spare parts and so on. , need to be repackaged and put back in the specified location.

In order to prevent the potential danger of floating and sliding, it is necessary to fix some items on the inner wall of the space station. In addition, they need to count and classify the remaining materials, so that in the future, Shenzhou 14 spacecraft will "seamlessly switch" their lives in orbit.

Pack "luggage"

Astronauts are ready to go home, of course, to pack up "luggage", which includes not only tangible items, but also "data carried" During the half-year "business trip", three astronauts conducted many experiments in the fields of space physics, life science, material science and astronomical exploration at Tiangong Space Station, which was of great scientific research value. The experimental data and records have to be "transported" from the core module of the space station to the return module of the Shenzhou 13 spacecraft and brought back to the ground as soon as possible.

In addition, the garbage accumulated by the space station in the past six months also needs to be "taken away". Before the astronauts return, they need to thoroughly "clean" the space station and do a good job of collecting and sorting it out. For example, residual food waste, sanitary products waste, waste generated by on-orbit experiments, etc. All need to be packed and classified, put into the orbital module, and then burned with the orbital module falling into the atmosphere.

take exercise

Astronauts do high-intensity physical exercise.

When astronauts work and live in the microgravity environment of the space station for a long time, their bodies will undergo great changes, such as body fluid loss, muscle atrophy, bone loss and even immune system disorder. In order to reduce the possible harm caused by these situations, astronauts should exercise in the space station every day. They need to do high-intensity exercise before going home and make adaptive adjustments in advance for returning to the ground.

In addition, the protective team of physiological effects of weightlessness in the astronaut ground center will provide "exercise prescription" according to the real-time physical condition of three astronauts. After they landed safely, the professional teams on the ground need to carry out protection and isolation as soon as possible according to the accumulated data and real-time detection, so as to help astronauts recover their physical and mental health and adapt to life on earth.

At the same time, in order to welcome the three astronauts back to China safely, the search and rescue team of Jiuquan Satellite Launch Center, together with other search and rescue forces, launched targeted training drills at the Dongfeng landing site.

It is reported that at present, the physical condition and psychological state of the three astronauts in the Shenzhou 13 crew are better than expected, which meets the requirements of returning to Earth.

Familiar with the process

Looking forward to seeing the safe landing of the return capsule as soon as possible.

Although the technology is mature and reliable, the journey of the spacecraft returning to Earth is still full of dangers and challenges. Generally speaking, astronauts must be familiar with the necessary operations and emergency plans during the whole return process, such as when to separate the manned spacecraft from the space station components and when to start the thrusters.

In addition, they have to carefully check the spacecraft's return capsule to ensure that all systems are working normally, especially the spacecraft's propulsion device and power control system.

Just like a house that has been uninhabited for a long time must be cut off from water and electricity, before astronauts leave the space station, they need to set their departure status and arrange electricity, water, gas and communication in place. According to the experience at home and abroad, they are likely to adjust forty or fifty items to ensure that the space station can transmit effective parameters to the ground in the subsequent unmanned flight mission.

Before leaving, astronauts must close all the doors of the space station and then return to Shenzhou 13 spacecraft from the core module. After sitting safely, fasten your seat belt and check the airtightness of the spacesuit and the integrity of the equipment. After everything is ready, we are waiting to "go"!

The trio on a business trip in space began to pack their bags and prepare to go home. Astronaut Shenzhou XIII will enter the preparation stage for return in the near future. In order to welcome the three astronauts to return to their homeland safely, the search and rescue team of Jiuquan Satellite Launch Center, together with other search and rescue forces, launched targeted training drills at the Dongfeng landing site. "Attention, all teams, we have entered the search area, please pay attention to observation." "The helicopter visually discovered the return capsule. ""After the return capsule landed, order the ground detachment to go to the disposal quickly. "

Recently, the space search and rescue team of Jiuquan Satellite Launch Center in China aimed at the mission and actively carried out sub-system and sub-professional search and rescue training with the air search and rescue forces, which made full preparations for the next joint search and rescue exercise and the implementation of the search and rescue mission of the Shenzhou 13 manned spacecraft.

This will be the second manned spacecraft search and rescue mission at Dongfeng Landing Site, and another glorious task and severe challenge for the space search and rescue team of Jiuquan Satellite Launch Center. As the main force of space search and rescue, all the search and rescue team members are doing a good job in normalized emergency search and rescue, and at the same time, they are also strengthening various training drills to ensure that the trio traveling in space can go home safely in the best state.

"We will further set strict standards, pay attention to training, set standards and tighten the style." "Adhere to pre-judgment, careful preparation, solid training, and Qi Xin's concerted efforts to ensure that the search and rescue recovery work is foolproof and a complete success." At the mobilization meeting for the search and rescue training of the Shenzhou-13 astronauts, a forceful "determination letter" showed the firm confidence of the search and rescue team members to win.

Zhu Qingxi, a member of the training team, said excitedly: "I feel honored to be able to participate in the search and rescue mission of Shenzhou XIII. To be an excellent search and rescue team member, you must be fearless and go forward bravely. In the next training, I will demand myself with stricter standards, fuller fighting spirit and more enterprising attitude, and strive to improve the theoretical knowledge and physical fitness level of search and rescue, so as to contribute to building the most reliable, safest and warmest space port for China astronauts to enter and leave space.
