The handwritten report on space knowledge is simple in content.

1. Handwritten content of spatial knowledge

The content of the space knowledge handwritten newspaper is 1. I am a little astronaut who writes newspaper materials by hand.

There are three contents below, for your reference!

1: What is an astronaut?

Astronauts, or astronauts, are full-name astronauts, referring to people who take space flight as their profession or have flown in space. The criteria for determining space flight are not completely uniform. In the United States, people who travel above 80 kilometers (50 miles) above sea level are called astronauts. The space flight defined by the International Aviation Federation (FAI) needs to exceed100km.

2. Milestones for astronauts:

The first astronaut in the world was yuri gagarin of the Soviet Union. He went into space in April of 196 1.

The first female astronaut was valentina Tresckow, who went into space on1June, 963. Alan shepard went into space in May 196 1 and became the first American astronaut.

On June 5438+1October 65438+May 2003, Yang Liwei became the first astronaut in China by Shenzhou 5. Other China people who have been to space include Lu Jie, Wang Ganjun, Jiao Lizhong and Zhang Fulin, all of whom are from the United States.

3. My Astronaut Journey (Imagination):

Finally, the commander began to count down: 10, 9, 8, 7, 6, 5, 4, 3, 2, 1, ignited, with a loud noise, a new manned rocket completely developed by our country, spewing blue flames and flying into space. This new spaceship is very advanced, and people are comfortable to sit in it. I am very carefree. The moon is bigger and bigger in my eyes, ah! Is this a dream? Still reality, it hurts when you pinch your thigh! It's true, it's true! I am very happy. Outside the porthole, colorful tracks, fleeting meteors and countless stars flashed in front of my eyes. Red, blue, yellow and green ... spread in the black sky, just like diamonds.

2. Cosmic scientific manuscripts.

Cosmic ray (co *** ic ray) generally refers to the earth that just formed from the solar nebula about 4.6 billion years ago.

At the beginning of the earth's birth, solid matter gathered in the core. At that time, because the earth's mass was not big enough, there was not enough gravity to absorb the atmosphere, and there was a strong solar wind (the particle flow that was constantly thrown out by the sun due to high temperature expansion was about 350~450 kilometers per second near the sun), so the first generation atmosphere dominated by hydrogen and helium was quickly blown into space. With the continuous rotation and aggregation of the earth, due to the condensation and contraction of itself and the heat generated by the transformation of radioactive substances (such as uranium and thorium), the primitive earth is constantly heating up, and its interior even reaches a hot level.

So heavy matter sinks inward, forming the core and mantle, while lighter matter is distributed on the surface, forming the crust. The newly formed crust is relatively weak, and the temperature inside the earth is very high, so volcanic activity is frequent, and many gases emitted by volcanoes constitute the second generation atmosphere, that is, the primitive atmosphere.

Primitive atmosphere is a reducing atmosphere without free oxygen, which mostly exists in the form of compounds, with large molecular weight and slow movement. At this time, the mass and gravity of the earth are enough to absorb the atmosphere, so the various components of the primitive atmosphere are not easy to escape. Later, the temperature of the earth's outer surface gradually decreased, and the water vapor condensed into rain, which fell to the depressed places on the earth's surface and became rivers, lakes and primitive oceans.

At that time, because there was no free oxygen (O2) in the atmosphere and no ozone (O3) layer in the sky to block and absorb ultraviolet radiation from the sun, ultraviolet rays could directly reach the earth's surface and become an energy source for synthesizing organic matter. In addition, the heat released by sky discharge and volcanic eruption, cosmic rays (high-energy particle flow from space, the source of which is unknown at present) and shock waves generated by meteors passing through the atmosphere (which will produce high temperatures of several thousand degrees Celsius to tens of thousands of degrees Celsius) also contribute to the synthesis of organic matter.

But the emission from the sky may be the most important, because this energy provides more energy and is released near the surface of the ocean, where the organic matter synthesized by reducing the atmosphere is easily washed into the primitive ocean. The solar system generated by cosmic rays runs in the disk-shaped Milky Way, moving relative to the center of the Milky Way, and reaching the farthest point of the center of the Milky Way every 62 million years.

And the whole "galaxy disk" is running at a speed of 200 kilometers per second in the hot gas wrapped around it. "The disk of the Milky Way is not as smooth as a frisbee," said the scientist. "It's flat."

Cosmic rays are produced when the "north" or front end of a galaxy rubs against the surrounding hot air.

3. What are the materials of China's space manuscript?

1On April 24th, 970, China's first artificial earth satellite "Dongfanghong-1" was successfully launched by the Long March-1 carrier rocket, and the music of "Dongfanghong" spread all over the world, thus China entered the era of space exploration.

1975165438+1On October 26th, the Long March II D carrier rocket successfully launched a recoverable satellite. After three days in orbit, the satellite was successfully recovered as scheduled, and China became the third country in the world to master the satellite recovery technology. Since 1970s, the remote sensing information obtained by recoverable satellite remote sensing has played an important role in land survey, resource survey, topographic mapping and disaster prediction.

1On April 8th, 984, cz-3 successfully launched Dongfanghong-2 experimental communication satellite, which indicated that China Aerospace mastered the technology of using hydrogen-oxygen engine and twice ignition in weightlessness, and became the fifth country in the world to develop and launch a geostationary orbit satellite. 1985 10 10 On 25th October, China * * announced that the Long March series of launch vehicles would undertake international launch and satellite launch business, and China Aerospace entered the international market.

From April 7th, 1990, when/KLOC-0 launched the Asia-1 communication satellite, by 2000, China had successfully launched 26 foreign satellites. On September 7th, 1988, cz-4 successfully launched Fengyun-1 meteorological satellite. Fengyun-1 is the first sun-synchronous polar-orbiting meteorological satellite in China, which has played a great role in meteorological observation, marine fishing, agricultural yield estimation, medium and long-term weather forecast and meteorological research.

1August, 1992 14, the Long March II bundled carrier rocket successfully launched the Australian "Ossett BI" communication satellite developed by Hughes Company of the United States. The long two-bundle launch vehicle has made great achievements in large thrust engine, large satellite fairing and rocket bundling technology.

China Aerospace has the ability to launch all kinds of large-load commercial satellites. 1997 May 12, the Long March 3A carrier rocket successfully launched Dongfanghong-3 communication satellite, and China achieved a major breakthrough in high-capacity communication satellite technology.

1On August 20th, 997, Long March 3B successfully launched the Philippine Mabuhai communication satellite. Long March 3 B uses a large thrust hydrogen-oxygen engine, which makes its synchronous transfer orbit carrying capacity reach 5 tons, and enhances China's competitiveness in the international commercial satellite launch market.

19991June14th, the Long March 4B carrier rocket successfully launched the Resource-1 satellite jointly developed by China and Brazil, and its comprehensive performance reached the international advanced level, which also set a good example for China's successful cooperation in the field of aerospace high technology. 1999165438+1On October 20th, the new Long March launch vehicle successfully launched the Shenzhou test spacecraft, and the spacecraft was successfully recovered on October 20th 165438+265438. China's historic breakthrough in manned space technology is a milestone in China's space history.

In June 1, 65438+1October 10, China successfully launched the Shenzhou II experimental spacecraft. After completing the space science and technology test mission in space as scheduled, he returned to the central area of Inner Mongolia on June+10/October 16, 65438. On March 25th, 2002, China successfully launched the Shenzhou III experimental spacecraft, circling the earth 108, and landed in central Inner Mongolia on 1 day.

On February 30th, 2002, at 65438, China successfully launched the Shenzhou IV spacecraft. From June 10 to June 16, 2003, China successfully conducted its first manned space flight. Chinese astronaut Yang Liwei flew 14 laps in Shenzhou 5 manned spacecraft, which lasted 2 1 hour for 23 minutes. After successfully completing all scheduled operations, he returned to the main landing site safely.

From June 65438+1October 12 to June 16, 2005, China successfully conducted its second manned space flight. China astronauts Fei and Nie Haisheng took the Shenzhou VI manned spacecraft to run 76 times in space, which lasted 4 days 19 hours and 33 minutes, realizing multi-person multi-day flight and safely returning to the main landing site. On 20071October 24th 18: 05, Chang 'e-1 probe was successfully launched from xichang satellite launch center by the Long March 3A carrier rocket.

It is the first lunar probe independently developed and launched by China. At 23: 35 on April 25th, 2008, China's first data relay satellite "Tianlian No.1 0 1" was successfully launched by the Long March III C carrier rocket in xichang satellite launch center. Shenzhou VII was launched at 2 1 on September 25th, 2008, and returned to the main landing site safely on September 28th.

4. Shen Qi's handwritten newspaper materials

Different from Shenzhou V and Shenzhou VI, Shenzhou VII rocket focuses on space suit and valve braking.

Because "Shenzhou VII" will realize spacewalk, whether astronauts can adapt to the sudden vacuum environment from cabin pressure, valve braking and spacesuit plays an important role. The spacewalk during Shenzhou VII requires higher assessment of astronauts.

Because the pressure in the spacesuit is lower than normal, it may release nitrogen in human tissues and form air embolism in blood vessels, leading to decompression sickness and even endangering people's lives. Therefore, after the astronauts put on the spacesuit, they must fully absorb the oxygen in the airlock, assist the working astronauts to return to the inner cabin (i.e. the orbital module), close the inner door, and then the airlock begins to decompress to vacuum, which is consistent with the vacuum state outside the spacecraft. At this time, the astronauts can leave the cabin.

When returning to the cabin after completing the mission of leaving the cabin, it is necessary to decompress the spacesuit to a certain extent, and then inflate the airlock. "Astronaut extravehicular activity is a difficult and high-risk activity."

According to experts, the spacewalk of Shenzhou VII requires astronauts to do full experiments and training on the ground, and the ground training is generally carried out in a neutral pool with certain requirements for specific gravity. This kind of pool is usually built in a large test room. There is a spaceship in the pool, which uses the buoyancy of water to simulate the weightlessness in space. Then the astronauts trained in the pool for entry and exit operations.

Experts say that "Shenzhou VII" will have several necessary conditions for astronauts to walk in space. First of all, it will provide the environment and conditions for astronauts to live and work outside the cabin, the most important of which is the extravehicular spacesuit, which has many functions such as meteor prevention, vacuum heat insulation and shielding, air tightness, pressure maintenance, ventilation and temperature regulation. The gloves of the spacesuit are both sealed and elastic, and the helmet is transparent and sealed.

Secondly, the extravehicular backpack has a control system and a communication system, and the control system is equipped with a jet device, so that the astronauts can control the walking direction. It is reported that space suits and backpacks are complex in structure, technically difficult and expensive. A set of spacesuits produced in the United States is about $65,438 +0.5 million.

Third, of course, there must be astronauts with skilled technical operation, good health and stable psychological quality. In order to adapt to the vacuum environment, "Shenzhou VII" spacesuit is much better than "Shenzhou VI" in air tightness, communication, excretion, communication, power supply and movable joints.

At the time of "Shenzhou 5", China's manned space flight was only an assessment of a person going into space one day. At that time, Yang Liwei only stayed in the return module, and the door of the orbital module was closed. Although "Shenzhou VI" is almost the same as "Shenzhou V" in appearance, the difference is that two astronauts will enter the orbital module from the return module and engage in multi-person and multi-day space flight procedures.

Experts made an image metaphor, "Two astronauts are active in' one room, one living room'. Speaking of Shenzhou VII, astronauts will not only move in the "one room and one living room", but also walk out of the "living room" and walk in space through the window on the side of the orbital module. Shenzhou VII has higher requirements for astronauts' life support system, extravehicular equipment and structural air tightness, so Shenzhou VII will be obviously different from Shenzhou VI in appearance and related systems will be different.

Usually, after the spacecraft is launched into space, astronauts will make adaptive preparations in the airlock room for 2-3 hours before leaving the cabin. They will wear extravehicular spacesuits, carry backpacks and carry supplies in the airlock. The spacesuit worn by astronauts who walk in space is huge, and the weight on the ground reaches 125 kg, which is not as easy as wearing a hat on the ground. It can only be put on with the help of other astronauts.

"So, there will be at least two astronauts on Shenzhou VII, so that we can cooperate with each other. As for how many people will leave the cabin, it is uncertain. It is estimated that a person walks in space. " Shenzhou VII will have three astronauts, one will walk out of the cabin, one will meet in the orbital module, and there will be people in the return module.

Extravehicular activities will include walking, operating, screwing and other installation equipment to prepare for the establishment of a space station in the future. China will carry out the Shenzhou VII manned space mission in the second half of this year. At present, all preparations are proceeding as planned.

It is reported that the "Shenzhou VII" flight will achieve a number of major technological breakthroughs. First of all, the number of astronauts will increase to three; Second, it will realize the first spacewalk of Chinese astronauts; Third, after the spacecraft enters the predetermined orbit, it releases a small satellite (referred to as "companion satellite" in this paper) at the right time, and so on. What can "companion star" do? According to Hong Kong Ta Kung Pao, the mission of this "companion star" is to take close-up photos of Shenzhou VII flying in orbit with a CCD stereo camera.

At that time, we will get the first three-dimensional external photograph of China spacecraft in orbit. This photo, set in space, shows the unique scenery of "Shenzhou VII" running at high speed, and will become a permanent historical witness of the Chinese nation's flying. Did Shenzhou VII just send a robot "photographer" into space? Ha ha, of course not! Prior to this, China has successfully launched several small satellites, and the technology of small satellites has reached maturity. Shenzhou VII took its companions into space, which is of even greater significance.

First of all, it is the change in the means of launching small satellites. In the past, China's small satellites were all launched into orbit by launch vehicles; This time, the small satellite was placed at the front end of the Shenzhou VII orbital module. When the spacecraft enters the predetermined orbit, it can be ejected automatically according to the instruction or released manually by the astronauts. The release method is more flexible. Choosing an opportunity means that you can release it when you want.

Secondly, the "companion star" can be used as a reconnaissance satellite. According to Hong Kong media, the companion of Shenzhou VII is equipped with a CCD stereo camera similar to Chang 'e-1, which can take high-definition images on the ground.

The "companion star" was released into orbit by "Shenzhou VII" to take photos and reconnaissance of the surface of interest. Third, "companion star" can be a very terrible space weapon.

Can be released by the spacecraft to carry out the task of attacking enemy space targets; It is also the most effective and loyal "bodyguard" of our ship-when the enemy attacks our ship, our ship can release the "companion star" in time and use the weapons it carries to destroy the enemy's attack weapons or perish together with them. The preferred launch time of Shenzhou VII manned spacecraft is.

5. handwritten newspaper about the universe

/view/2496

In Chinese, "Yu" stands for up and down four directions, that is, all the space, and "Zhou" stands for all the time, that is, all the time. Yu: infinite space, and Zhou: infinite time. So the word "universe" has the meaning of "all time and space". Linking the concept of "universe" with time and space embodies the wisdom of the ancient people in China.

The universe is a unity composed of space, time, matter and energy.

The universe is the general name of all things, and it is the unity of time and space. The universe is a material world, which exists objectively regardless of human will and is in constant movement and development. The universe is diverse and unified; Diversity of material manifestations; Unity lies in its materiality.

6. My space dream handwritten newspaper content

On June 1 1, 20 17: 38, Shenzhou 10 rose into the sky, shouldering the heavy responsibility of China's first manned space rendezvous and docking, representing that China is gradually realizing its space dream. The task will be to "pick up the missing pieces" of the "Shenjiu" manned rendezvous and docking technology. The spaceship will fly into space with three astronauts, Nie Haisheng, Zhang and Wang Yaping.

Shenzhou-10 will hold space science lectures and science education activities for young people for the first time, which will be a highlight of this mission. According to experts, popular science education is a very important function of aerospace. Using manned space flight to reveal the special phenomena and laws of space microgravity to primary and secondary school students can stimulate young people's enthusiasm for scientific exploration and accumulate experience for making full use of space station resources to carry out popular science activities in the future. In fact, this is also an important part of space activities in all countries of the world. In addition, the seemingly simple space teaching needs the support of the communication link between heaven and earth, which also challenges the coordination among the three astronauts.

How does an object move in weightlessness? What is the state of liquid in space? During the Shenzhou-10 mission, audiences all over the country can watch these phenomena live from space.

For the first time, Shenzhou-10 astronauts will carry out popular science education activities such as space teaching and interactive communication between heaven and earth for primary and secondary school students, which will become a highlight of Shenzhou-10 mission.

This popular science education activity is an attempt to popularize space knowledge in manned space activities in China. It is hoped that this popular science education activity can further stimulate young people's yearning for space and enthusiasm for learning scientific and technological knowledge.

Wang Yaping, a female astronaut, is the first "space teacher" in China. For the teaching content, it is mainly to let teenagers know the characteristics of object movement in microgravity environment, understand the role of liquid surface tension, and deepen their understanding of basic physical concepts such as mass, weight and Newton's law. Astronauts will give on-orbit explanations and experimental demonstrations, and have two-way interaction with teachers and students on the ground.

Through this activity, teenagers get close to space, understand space and love space.

Give a good review!
