our space shuttles “space bus” – section 9 of the Shenzhou series of spacecraft on a journey. At the moment, it is carrying three astronauts, along a familiar piece of “high road” toward the vast space in the “home” One Temple.

Shenzhou spacecraft 4th manned expedition. Four times of war and across. Again the familiar sound of “Ignition”, we have witnessed a great leap journey: the Shenzhou a one day, God six two five days, the seven gods of three days. This time, the Shenzhou 9th plan a trip up to 13 days!

13 days in space, what it means? The spacecraft fly 16 laps a day, speaking only from the day and night, the astronauts will experience the 208 “day and night cycle This time taken the steps were not small. Chinese astronauts director of the Center

“The God nine tasks, in addition to the breakthrough in manned rendezvous and docking, as well as a very important feature is that our manned space flight by short-term transition to medium and long term.” Chen Shan also said that this transition astronauts protection of life and the life of our aircraft inside the product, quality is a big challenge and test. “

this go long journey, this process challenging. The three astronauts feel sincerely proud at the same time, following the interpretation of experts, feel the tour challenging journey.

weight loss challenge

floating feeling is not so romantic

pure space weightlessness, The ground can not be completely simulated. Even the big move of the “G-Force One” aircraft flying parabolic, would only last 30 seconds of weightlessness experience. So-called Heaven and Hell, that is what I mean. “Astronaut Jing Haipeng, said:” The first time flying astronauts to the first hurdle of the sky, is to adapt to weightlessness. “

flight Most of the time of the astronauts are “Gone with the Wind”. However, floating in the weightless environment feeling far as romantic people see or imagine.

International Space Station almost every time when the arrival of the new and the astronauts witness such a “joke”: novice running time, not to hit something else is bumping into people. Abroad, an active astronaut, said: “When you first attempt, you cow like a china shop, like bold.”

“you have to quickly learn In addition to fingertip touch anything the skills learned to their own fixed in the air, learn to move from one place to another place. “Jing Haipeng,” for the astronauts, these are the precious space life skills. “

the challenges of life

eat and drink Lazard sleep technology job

space dinner needs to the table? How to drink water? How on the toilet? How to sleep? In the days that followed, the astronauts live in space 11 kicked off. Soon, people will witness in the weightless environment of space, the astronauts eat and drink Lazard sleep all technical job –

eat and drink: As the saying goes, “people are iron, rice, steel, Dayton eat hungry. “in one or two days and flight of the space flight ten days, the requirements of food is definitely quite different. “We designed the recipes to meet the medium-and long-term flight.” China Astronaut Center Renchen Shan Kwong said: “By the time you will be able to see, to taste, to ensure that astronauts do not worry about eating from the pattern.” Eat and drink what solved, and how to eat how to drink the same problem in space, after all, can not reach the plate, eat, pick up the cup to drink.

Lazard: toilet in space, is a cumbersome, complex thing. Spacecraft cabin space is limited and handled properly, the urine will float out the day of that space really can not over. Especially this time there is a female astronaut, go to the toilet all the test equipment and people.

sleep: space day and night, replacement frequency is 16 times that of the ground, in the end it is the rhythm of life living in accordance with the sunrise, sunset and interest “, or adhere to in accordance with the ground,” GMT “on work ? Liu Weibo overall director of the China Astronaut Center of the astronaut system, told reporters: “astronauts in accordance with the ground work and rest time life in heaven.” The problem would be to how to ensure the privacy and comfort of the rest of the? Let us wait and see. Psychological challenges of

space calm is really calm

In now

, people like to use to calm the word to describe a person’s psychological qualities. For the astronaut is in space, calm, really calm.

space flight is an important part of the spirit of challenge, because only two people accompanying you for a long time if you a bad mood, can not go for a walk when I learned to upset to talk to the companion , do not worry about things in mind. an International Space Station astronauts in the blog writes.

space hero Yang Liwei is also God six Shenzhou VII mission, said: “I am particularly concerned about the mental state of the astronauts, after all, the feeling of vast space and on the ground are two different things.”

So far, studies have shown that: long-term space flight, and social isolation, environmental narrow, limited mobility, as well as a variety of potential risks, gave the astronauts caused a great deal of psychological pressure.

with the international space station on the flight time can not be compared, but this time God nine 13-day mission, marking China’s manned spaceflight by short-term and long-term transition. Therefore, the astronauts’ psychological adjustment and support, also constitute an important part of this mission.

“We arranged for the astronauts entertained, still on the ground to set the psychological team at any time call heaven and earth to provide psychological support.” Huang Weifen disclose, deputy chief designer of the manned space project astronauts : “In the days that followed, people will see a variety of entertainment life of the three astronauts.”

health challenges

surface on a variety of physical ailments test

astronaut orthostatic decline in muscle atrophy, etc. The problem is I worry about this core issue. “deputy chief designer of the manned space project astronauts Li Yinghui, Shenzhou, Shenzhou VI, the Shenzhou VII flight time is shorter, so troubled by the change of the space environment to astronauts less. In a few days of flight, the astronauts easily create some problems in the cardiovascular system, space motion sickness, such as syncope, facial swelling, and standing capacity decline. But this time is different.

“The manned space missions in line with the mid-time of flight, we will seize this opportunity, the implementation of protective measures physiological effects of weightlessness for the first time in orbit and protection assessment, the first system to carry out the test of aerospace medicine space. before the flight is the first time, comprehensive and dynamic monitoring of important physiological and biochemical indexes, the astronauts for health maintenance of the future long-duration space flight astronauts provide strong support for this is also the mission of our greatest challenges, “said Li Yinghui.

measured through challenges

world real-time communication of a transmission “line”

heaven, 3 astronaut in flight; the ground, a lot of professional support team to see. Between them at any time may be the communication, means of communication from the high-definition video telephony, e-mail to a short message, the message format from the text, images, video to PPT courseware, anything is possible.

to ensure that all of this become a reality, land sea and the sky-based measure root of heaven and earth pass network transfer “line”.

from Shenzhou flying, Yang Liwei, “I saw a beautiful home” cordial screen and voice to God six flying, Fei Long, Nie Haisheng with their families warm and call; from Shenzhou VII flying Zhai Zhigang’s spacewalk reflections to a clear picture of God eight Temple rendezvous and docking – the root of heaven and earth transmission line is undoubtedly wider and wider, more smooth.

world calls a one-way screen transfer – only on the ground to see the astronauts, the astronauts can not see the ground. This time, we want to achieve for the first time world interaction, so that the world truly high-definition video telephony. “manned space flight project monitoring and control communication system designers Wangrui Jun said:” world of real-time high-quality pictures or voice communications, the measure through the system one of the test. “

another test is still monitoring and control. Qian Weiping, chief architect of manned space flight project monitoring and control communication system, monitoring of the task difficulty is the long life cycle, control more often than eight tasks with God. The spacecraft Shenzhou No. 9 before entering the self-guided stage, you need to be completed in the measurement and control system under the command of 5 orbit.

In addition, monitoring and control system but also time space debris monitoring and early warning, if there are unusual circumstances, in accordance with pre-established emergency response plans for emergency flight control, Temple One or Shenzhou on the 9th to ensure the safety of the spacecraft.

“safety is always the biggest challenge.” Qian Weiping said, because of this mission the astronauts, emergency breakdown plan than God, more than eight hundreds.

technical challenges

space to open the spacecraft requires real skill

compared to God eight tasks, the difficulty of manned rendezvous and docking technology only to rise. Chinese astronauts, deputy director of Baiyan Jiang opinion, the challenge at least two aspects:

First, compared to the Shenzhou VIII and Temple One rendezvous and docking in the shaded area the sun according to District automated rendezvous and docking tasks more difficult. Well known, like the camera directly to the sun can not make good photo, optical measuring instruments also need an appropriate sun angle of incidence, in order to play the features and benefits.

difficulty unprecedented manual rendezvous and docking. “This is a Chinese astronaut in space for the first time driving the spacecraft, think about the tension in his first road car to mention this is in space, it is definitely a test of real skills.” Baiyan Jiang said, “In the complex environment of the space, astronauts continuously in a very short period of time on the complex relationship between the two aircraft, fast, comprehensive, accurate judgment, and at the same time manipulating two handles real-time precise control of the six directions of the spacecraft, astronauts operational capability and psychological stability of unprecedented challenges. “

environmental challenges

combination of environmental control is a major event

interview, the deputy chief designer of the manned space project space laboratory system peak, he kept told reporters that the next few days, the astronauts assigned to the “Temple” must not miss.

“This means that China’s first visit to be verified in-orbit vehicle, means that our combination of environmental control technology.” Peak further explained that the rendezvous and docking mission, will be the first in-orbit Open the door of the Temple One JEM, and the spacecraft re-entry capsule, the orbital module and Temple One JEM connectivity, Temple One of the environmental control and life support resources to control the three-compartment model, 1 Torr “environmental control mode.

combination of environmental control is a major event is directly related to the ability of survival in the combination of which “peak, dynamic water and gas separation technologies of concern under conditions of weightlessness, oxygen generation technology and the condensate collection storage performance, should the first time during this mission in-orbit validation. They are one of the core technology of regenerative environmental control and life support systems is a key technology to achieve medium-and long-term manned space flight.

Experimental challenge

heaven experimental arrangements, full to the brim

has never been what a space mission like this time so many experimental task: project carried out for the first time in orbit astronauts heart function tests, skeletal muscle atrophy in rail applications, for the first time control systems, to carry out in-orbit microbial detection for the first time, for the first time to carry out the pharmacokinetics of paracetamol in the weightless conditions research …

for the first time in orbit experimental project as many as 13 days in space living arrangements was full to the brim. How to work every day living arrangements, test planning and resilience of the three astronauts. In particular, the female astronaut Liu Yang, the experiment will be great to play her as a woman carefully and other advantages.

never what a space mission like this time, the requirements of the experimental capabilities of the astronauts is so high. The mission, not the other experimental load only astronaut medical monitoring equipment, aerospace, medical laboratory equipment up to forty to fifty kinds products, these products correspond to the experimental project, operational complexity, are unprecedented.

China Astronaut Center chief engineer Jiang Guohua summarized the characteristics of the task space experiments, said: “The space experiment with new and complicated to operate, demanding the experimental capabilities of the astronauts.”
