AES - artificial satellites of the planet Earth. The first artificial satellites from the planet earth Artificial earth satellites story for the middle group
Interesting Facts about artificial satellites of the Earth attract the attention of almost every person, since this topic is very interesting. The space age has already begun more than half a century ago, and during all this time a large number of curious information.
- The first satellite that went to extraterrestrial spaces was called PS-1 or the simplest satellite. It was launched into orbit by a launch vehicle, the launch was carried out from the USSR test site, now it is called Baikonur. This event marked the beginning of space exploration.
- PS-1 weight approximately 83 kg. It looked like a ball with a diameter of 58 cm. It had four antennas about three meters long, they were used to transmit signals. At 315 seconds after the launch, PS-1 issued the first callsigns that the whole world was looking forward to.
- The pioneer stayed in orbit for 92 days. During this time, he managed to overcome 60 million km, which is equal to 1440 revolutions around the globe. Its radio transmitter was able to hold out for two weeks after launch.
- The creator of the pioneer Sergey Korolev could receive the Nobel Prize, but since in Soviet times everything was common, the achievement of the great scientist was "a victory for the entire Soviet people." For a long nine years it was not even known who could give the world such an achievement.
- Thanks to the first IP, it was possible to study the surface layers of the ionosphere. He also helped to obtain information about the operating conditions of the equipment, they were very useful during the next launches of the PS-1 followers.
- Newspapers of the time wrote that a satellite could be seen in the sky without the use of special devices but it wasn't. What everyone took for the PS-1 was the central block of the rocket. It weighed about seven tons, it was put into orbit simultaneously with the satellite, more precisely, it launched PS-1 there. The block “floated” in the sky until it burned out.
- Today, approximately 13,000 artificial satellites plow the expanses around the globe.. They are very useful, as they "can do" many important things. Thanks to them, satellite phones can work anywhere in our planet, just like satellite navigation systems; ships come to port; satellite TV works. When browsing the maps of the most famous search engines, we often come across a “satellite view” tab, which makes it possible to see photos of any part of the planet from a great height.
- The launch pattern is akin to throwing a stone. More precisely, the satellite must be thrown at such a speed that it can rotate around the planet on its own. The parameters of such a throw: 8 km / s, and this must be done outside the atmosphere. Otherwise, air friction will become a hindrance. If everything worked out, then the satellite will live in near-Earth orbit, without outside help and without stopping.
- In the early 2000s, a copy of the PS-1 was sold at the famous eBay auction.. According to some experts, during the Soviet era, about 20 identical models were created, on which testing and demonstration were carried out. The exact number of copies is still unknown, since the information was secret, but to this day many museums claim that there is an analogue of PS-1 in their collection.
- In the history of satellite launches, there was the only case of its destruction by a meteorite.. It was registered in 1993. It was the IS of the European Space Agency "Olympus".
- In 1978, the first GPS satellite was launched..
- In the same 1978, a spy satellite launched by the USSR fell.. It was called Cosmos 954, included nuclear reactor. The result was the contamination of an area of more than 100,000 square kilometers.

planets
Cosmodrome. I stand on the gangway, adjusting my helmet.
"Goodbye!" - shout to dad, "Goodbye!" - everyone.
The sky rose above us, leaving a trail,
The flame was beating red light towards the planets.
(Yu. Lutskevich)
Nine planets revolve around the sun: Mercury, Venus and Earth. Mars, Jupiter, Saturn, Uranus, Neptune and Pluto.
Each of the planets moves around the sun in its own way. This path is called an orbit.
There are also small planets - invisible. Most of them are between Mars and Jupiter.
The sun, together with the major and minor planets, makes up solar system.
In the solar system, people live only on Earth. There are no living beings on other planets.
Even in ancient times, people noticed several luminaries wandering among the stars. These luminaries became known as planets. Planets don't shine by their own light like stars do. Planets are visible in the sky because they are illuminated by the sun. At first glance, they look like bright stars, but the planets do not twinkle. They glow with a steady light. They are brighter than the stars. Through binoculars, you can see that the planets are visible not as dots, but as small disks, circles.
For many centuries, people have studied the planets with the naked eye, then with the help of a telescope - a spotting scope with magnifying glasses. Now the planets are studied with the help of automatic interplanetary stations. They fly up to the planets and photograph the surface of the planet from a close distance.
Astronauts did not fly to other planets. They flew around the Earth and to the Earth's satellite - the Moon.
Teacher's story about Mercury
This planet is closest to the Sun. Mercury seems huge. Three times more than the Earth.
Mercury is a small planet. It is 20 times smaller than the Earth. This is a lifeless stone ball with mountains, deep ravines and bare, dull stones.
A day on Mercury lasts 90 days - three months. During such a long day, the sun very much heats the surface of Mercury up to 400 degrees. The heat is unbearable. Then for 90 days comes a black, impenetrable night. Terrible cold. Frost - 150 degrees.
Mercury is easier to see in southern latitudes: it appears in the sky in the evening. Either in the morning (in the first two hours after sunset), then in the early morning (two hours before dawn). No wonder our distant ancestors were not easy to guess that the morning and evening stars are the same luminary, and they called Set and Horus (Egyptians), Buddha and Roginea (Indians), Apollo and Hermes (Greeks).
Mercury, like the moon, shines by reflected sunlight. Mercury is deprived of an atmosphere, which means that life there is impossible not only because of the unbearable temperature for living beings, but also because they have nothing to breathe on Mercury.
The surface of Mercury is dotted with craters - people learned about this by obtaining an image of its surface taken in 1974 by the American spacecraft Mariner 10.
Teacher's story about Venus
Venus is not a star, but a planet, just like our Earth. All the planets in the solar system revolve around the sun, each in its own circle. Venus is the second planet from the Sun. It is closer to the Sun than the Earth. The hot rays of the sun make the surface of Venus very hot. The temperature on Venus is +500 degrees. Not a single living being can live in such inferno.
There are no forests or seas on Venus. The air on this planet is terribly poisonous and heavy. It presses with its weight with such force as a layer of water one kilometer thick would press on us.
On Venus, hurricanes whistle and howl, clouds of dust raised by the wind are carried, stony deserts and rocks stretch. Hot sand.
There are so many clouds over Venus. That she seems to be wrapped in white cotton wool. Sunlight does not penetrate through dense clouds, therefore there is eternal night on the planet.
Venus is about the same size as our Earth. It is closer to the Sun than the Earth. And manages to fly around the sun in just seven months. Therefore, a year on Venus lasts seven months.
From Earth, Venus appears to be an extraordinarily beautiful planet.
She appears in the sky only in the morning or only in the evening, and people call her the Morning Star, who is the Evening Star. It shines with soft white light. No star can match the beautiful brilliance of Venus.
People named this planet after the goddess of beauty and composed beautiful tales about her. It seemed to them that this beautiful girl was riding across the sky on a silver chariot drawn by snow-white horses.
The teacher's story about the Earth
There is one garden planet in this cold space
Only here the forests rustle birds calling migratory,
Only on it alone lilies of the valley bloom in green grass,
And dragonflies only look into the river in surprise ...
Take care of your planet - there is no other like it!
Earth is the third planet in the solar system. Like all planets, it moves around the sun. Earth is a satellite of the Sun.
Our planet is not just moving, but rushing through outer space faster than any rocket. And although it flies very fast. It only goes around the sun once a year. It's a very long way!
The earth doesn't just revolve around the sun. It also rotates around its axis, spinning like a top. The earth exposes the sun to one side, then the other. Until it turns once around its axis, 24 hours will pass, that is, a day - day and night.
When astronauts look at our planet from space, it seems to them a luminous ball of beautiful blue color.
The fact that the Earth is round, people guessed in the old days. At first they thought that the Earth was a round pancake and one could walk to its edge, but not a single daredevil ever reached the edge of the Earth.
And so the sailor - traveler Maggelan on five ships decided to go around the Earth.
For three years the ships sailed forward and forward, without changing direction and checking their path by the stars. Four ships were lost in the rough waters of the ocean. And only one ship called "Victoria" circled the Earth and returned to the port from the other, opposite side.
The teacher's story about Mars
Mars is the fourth planet in the solar system and is a close neighbor of the Earth.
Even in ancient times, people noticed a bright orange fiery star in the sky. And they named it in honor of the god of war - Mars. It is curious that so many writers - science fiction writers inhabited the red planet with living beings - silt with militant monsters, or similar to people, or hostile to them. And today, journalists call Mars the Bermuda Triangle? Almost all space missions to Mars end in failure.
As on Earth, on Mars there are days and nights, as well as winter, spring, summer, autumn. Each of these seasons is twice as long as on Earth. This is because on Mars, a year is almost two Earth years, because Mars is farther from the Sun, and it takes more time to go around the sun. Well, if Mars is farther from the Sun, then the sun heats worse there. Therefore, the winter there is more severe, and the summer is colder. The most heat during the day on Mars + 15 degrees, and at night - 100 degrees below zero.
During the day, the sky of Mars seems soft pink. This color is given to it by Martian dust illuminated by the Sun.
At the end of the 20th century, the Vikings spacecraft transmitted to Earth an image of the planet Mars - absolutely lifeless landscapes, similar to earthly deserts. Uncomfortable and unfriendly on Mars. Strong winds raise clouds of red Martian dust, huge deserts strewn with stones. Mountains with sharp peaks rise up.
The air on Mars is made up of a gas that humans cannot breathe. There is no oxygen or water on Mars. There is no life there.
Teacher's story about Jupiter
Jupiter has twice played an important role in the history of the astronomer. It became the first planet to have moons discovered. It happened almost four hundred years ago. The author of the discovery is the world famous scientist Galileo. The rapid and clearly visible movement of Jupiter's moons makes them a very convenient sky clock, and sailors used to use them to determine the position of a ship on the high seas.
And further. Jupiter and its satellite helped to solve one of the oldest mysteries: does light spread at lightning speed or is its speed not so great? Through complex calculations based on observations, O. Romer determined that light moves quickly at a speed of 3000 km / s
Jupiter is the fifth and largest planet in our solar system. This is a giant planet. It is ten times the size of the Earth.
Bright Jupiter moves slowly and majestically around the Sun. Twenty years will pass on Earth, and Jupiter will fly around our sun only once. Very far from the star, a very long way he has to go.
Jupiter is so far from the Sun that the sun's rays do not warm it at all. This is a very cold planet.
Jupiter does not have a solid surface like Earth, Venus, Maar and Mercury. It is a huge ball of dense clouds of dust and gas.
Terrible storms and thunderstorms rage on Jupiter, which do not happen on Earth. This is the most restless and formidable planet.
The air on Jupiter is poisonous and unbreathable.
Jupiter spins around its axis very quickly, like a top. Only ten hours last a day on Jupiter: five hours a day and five hours a night.
Jupiter has 16 satellites that revolve around it, each of them with its own history and its own mysteries, which mankind managed to solve only in the space age. You will learn about it. When you get older and read books on astronomy.
The teacher's story about Saturn
There is one star in the sky
Which one, I won't say
But every evening from the window
I look at her.
She shimmers so bright!
And somewhere in the sea
Now, probably a sailor
It guides the way
(G. Kruzhkov)
It is the sixth planet in the solar system. Saturn, like all planets. It makes its flight around the Sun. The farther a planet is from the sun, the longer its path. It takes Saturn 30 Earth years to complete one circle.
Light yellow Saturn looks much more modest than orange Jupiter. It does not have, like its neighbor, colorful cloud cover. But there are rings that other planets do not have. They excited the imagination of many scientists with their unique shape. Only three rings are visible from Earth. These rings are thin, but very wide - many thousands of kilometers wide. They consist of stones and ice, which, like satellites, move around Saturn. There are so many of these small stones and ice floes that they merge into continuous rings.
Saturn does not have a solid surface like Earth, Venus or Mars. Saturn. Like Jupiter, it is a giant ball of gas, 9 times the size of the Earth.
This planet is very far from the Sun, so the solar heat does not reach Saturn. Eternal cold reigns there, frost up to -180 degrees.
Like all planets, Saturn revolves around itself. Saturn completes one rotation on its axis in 10 hours.
Moon
If you try hard
If you really want
Can you go up to the sky
And reach the sun.
And seriously, not pretend
Get to know the moon
Walk on it for a bit.
And return home again. (S. Baruzdin.)
The moon is not a star or a planet. She is a satellite of the Earth, a large stone ball, which is several times smaller than the earth.
The Moon is the closest celestial body to the Earth, the distance to it is 384 thousand kilometers.
If you look at the moon through binoculars, you can see dark and light spots on it. Light spots are lunar seas. In fact, there is not a drop of water in these seas. Previously, people did not know this, which is why they called them seas.
There is no water on the moon. No air. There is neither rain nor snow. You can't live on the moon.
The entire surface of the moon is covered with a thick layer of dust. Astronauts who have landed on the moon speak. That it looks like it hasn't been dusted for years.
On the surface of the moon during the day there is heat up to 130 degrees, and at night - frost - 170 degrees.
That's why the moon is shining. that the sun illuminates it. From the Earth, the Moon can be seen either as a round one, or as a sickle, sometimes it is not visible at all. This is because. That it is illuminated by the Sun in different ways, and we see only the illuminated part of the Moon. Therefore, it changes its appearance all the time. The moon moves around the Earth and goes around it once a month.
American astronauts were the first to fly to the moon in spacecraft.
Stars
Who looked at the starry dome
Late autumn frosty
He saw how the star Swan
Rises to the zenith
He heard how in the blue sky
The starry lyre is ringing.
In the old days, people thought that the stars were shining lanterns. Suspended from the crystal vault of the sky. After all, they did not yet know that each star is a distant Sun, which is billions of times larger than the Earth.
Stars are huge hot balls, similar to our Sun. They are very far from the Earth and therefore do not heat and seem very small.
There are a lot of stars in the sky, and to understand them. People have combined groups of stars into constellations. Constellations and the brightest stars people gave names.
In the night sky, the stars twinkle in different colors: blue, white, yellow, red.
White and blue stars are very, very hot. They are hotter than the sun. Yellow stars are colder than white ones. They are about the same as our Sun. Reddish stars are colder than the Sun.
Stars differ in size from each other: there are red giants, normal stars and white dwarfs.
Our Sun is a star. It is possible that other stars similar to the Sun have planets and their satellites. Perhaps there is life on those planets. But we don't know about that yet.
Sun
Shine on us, sun, shine!
It's easy to live with you.
And even a song on the way
Sings by itself.
From us behind the clouds - clouds
Don't go, don't
And the forest, and the field, and the river are happy with the warmth and the sun.
Listen to my song: shine from morning to night
And I'll sing for you, I'll sing when you want. (Y.Akim)
The sun is a huge fireball. The temperature on the surface of the Sun is 20 million degrees.
It seems to us that the Sun is a small circle. That's why. That it is located at a very large distance from the Earth. In fact, the Sun is huge. It is 109 times larger than the Earth, the sun - the ball - the giant. If you could put the sun next to the earth, it would look like a big soccer ball next to a pea.
From the Earth to the Sun 150 million kilometers. Therefore, the sun's rays do not burn, but only warm and illuminate our planet.
Without the Sun, there would be no life on earth. Plants, animals and people live only because the sun gives them life. This was understood even by ancient people and worshiped the Sun as a god. They thanked him for his warmth and greeted him as he rose in the morning.
The Sun is the closest star to Earth and is the center of the solar system. Our planet Earth is one of the nine planets in the solar system.
Comets
Spreading its fiery tail, the comet rushes between the stars Rushing at wild speeds, was visiting the sun And saw the Earth in the distance and new satellites of the Earth and was carried away from the Earth, ships flew behind it! (G.Sapir)
Comets are celestial travelers. These are huge blocks of stone and ice. Sometimes they are called "dirty snowballs" for this.
But there are comets. Which from time to time return to the Sun. For example, Halley's comet does this every 76 years. Halley is the scientist who first noticed this comet. Comets are always given the names of the people who discovered them.
More recently, the Americans Hale and Bopp discovered a new bright comet, which flew into the solar system for the first time. Now they call it that - comet - Hale - Bopp.
In March and April 1997, she appeared in the sky in the morning and evening. And anyone could admire its silvery sheen. This comet is a very rare guest. Scientists believe that the next time it will approach in about two and a half thousand years.
When a comet approaches the Sun, it can be seen in the sky even without binoculars and a telescope, because it has a luminous tail. This is a comet tail - the plume is formed from dust and gas. A comet flies away from the Sun, its body cools down, the tail disappears, and a cold block again travels in space. Comet tails are not terrible for the Earth, although they frightened people in antiquity. more dangerous solid comets. But, fortunately, outer space is so huge that we can not be afraid of these meetings.
astronauts
The chief designer told me: - The takeoff will not be very smooth ...
There will be a heart, maybe often go to the heels ...
Lift up your heels - that's all right
And then for the whole flight the heart will not go to the heels ... (A. Shalygin)
This profession has appeared quite recently. An astronaut is a person who tests space technology and works on it in space.
Now there are astronauts in almost all countries of the world. But spaceships are built and sent into space by only two countries in the world - in Russia and America. Cosmonauts from all over the world worked on Russian spaceships: from France, from America. From Japan, from China and from many other countries.
Yuri Alekseevich Gagarin was the first cosmonaut on Earth. On April 12, 1961, on the Vostok 2 spacecraft, he flew around the Earth once in 1 hour 48 minutes. He returned to Earth alive and well. And scientists decided that a person can live and work in space.
Now cosmonauts spend many months, and some more than a year, at space scientific stations.
The Mir space station was built in Russia. It has been flying and operating in Earth orbit since 1986. One crew of cosmonauts is replaced by another. Not a single hour stops work on the space station. Astronauts observe the stars, the planet and the Sun, take pictures and study the Earth. They take care of the plants and animals that live on the station, repair their space house, and conduct many scientific experiments.
Space flight is monitored from Earth from the control center.
Many astronauts have flown into space several times already.
Astronauts are courageous people. They live and work in unusual conditions - in zero gravity, in a silent and dangerous space.
Astronauts
American cosmonauts are called astronauts. American astronauts were the first people to land on the moon.
In July 1969, the American ship "Apollo" rushed the inhabitants of the Earth to our space neighbor. As the spacecraft approached the moon, a special lunar cabin separated from it. And then astronauts Neil Armstrong and Edwin Aldrin descended to the surface of the moon.
For several hours, earthlings walked on the surface of the moon, looking at the surroundings, collecting stones and photographing lunar landscapes.
Astronauts walked on the Moon in special spacesuits, and talked to each other by radiotelephone, because there is no air on the Moon and not a voice is heard. No sounds. The astronauts moved on the moon as if bouncing. Pushing off first with one foot, then with the other, because objects on the Moon are many times lighter than on Earth.
They left on the moon medals with portraits of the first cosmonauts and a sign with the words "We arrived in peace on behalf of all mankind." Who knows, maybe some alien will read this letter someday from the planet Earth.
The astronauts then returned to the spacecraft, which was waiting for them in lunar orbit. And three days later, the Apollo splashed down in the Pacific Ocean.
Thus ended the first flight to the moon. After that, several times American astronauts flew to the moon.
On other planets and their satellites, the inhabitants of the Earth have not yet been, but sent automatic space stations there.
Astronomers
How tempting to become an astronomer, intimately familiar with the universe!
It would not be bad at all: to observe the work of Saturn,
Admire the constellation Lyra, discover black holes
And be sure to compose a treatise - “Study the depths of the Universe!”
Astronomers are scientists who observe and study the stars.
In those distant times, when people did not yet know how to read and write, they watched with surprise what was happening in the sky. It seemed to them that the sky is a crystal cap that covers the Earth, and the stars are attached to the sky for decoration.
Ancient people thought that the Earth is stationary, and the Sun, Moon and stars revolve around the Earth.
Many years later, astronomer Nicolaus Copernicus proved that the Earth revolves around the Sun.
Another scientist, Newton, understood. Why the planets do not fall: they are mutually attracted to each other and do not allow each other to move away from themselves or approach them. Therefore, they all fly around the Sun, each in its own way.
So gradually, scientists discovered the secrets of the cosmos.
Ancient astronomers studied the stars without special instruments, observing the sky from Earth. In the Middle Ages, scientists invented the spyglass and telescope to look at distant stars. Now artificial satellites and space stations fly in space, which explore the planets and stars.
The universe still has many mysteries, and astronomers will have enough work to do for a long time.
Satellite
What kind of relative of the moon is there,
nephew or granddaughter
Flickers between the clouds? -
Yes, it's a satellite! Here are those times!
He is a satellite of each of us and the whole Earth in general.
The satellite was created by hands, and then on the rocket
Delivered to these distances (Yu. Yakovlev).
This is the name of the celestial body. Who circles around the other all the time. Many planets have natural satellites. The Earth also has a natural satellite - the Moon - and a lot of artificial satellites made by human hands.
Maybe you have seen a twinkling star rolling across the night sky? This asterisk is a satellite illuminated by the rays of the Sun.
The first Earth satellite was launched in Russia on October 4, 1957. Then the same satellites were launched in the USA and other countries. Now thousands of artificial satellites are flying around the Earth.
Satellites help to watch TV shows, conduct telephone conversations, send and receive telegrams, and connect people with each other. That is why they are called connected.
With the help of satellites, the captain guides the ship through the boundless waters of the ocean. As satellites fly around the earth, they send out radio signals continuously. Based on these signals, the captain determines where the ship should sail.
Circling around the Earth, the satellite with the help of television cameras observes our planet. Clouds, hurricanes, storms are clearly visible from the flight altitude. You can see how fast they move. The satellite transmits its observations to Earth, and meteorologists use them to make a weather forecast. People have created artificial satellites in order to help them study the Earth, the Sun, planets, stars, and unravel the mysteries of nature.
Universe
The entire vast world that is outside the Earth is called space. Space is also called by another word - the Universe.
The cosmos, or universe, has no end or limit. The universe is filled with countless stars, planets, comets and other celestial bodies. Clouds of cosmic dust and gas are swirling in space. In this interstellar desert reigns cosmic cold and darkness. There is no air in space.
There is not a single celestial body in the universe that would stand still. They are all moving. It seems to us that the stars are motionless. But in fact, the stars are so far away that we do not notice that they are rushing through space with great speed.
In this infinite and eternal Universe, our Earth is a small planet, and our Sun is an ordinary star closest to the Earth.
Our Earth flies in space along with other celestial bodies.
Every star, planet, comet or some other celestial body moves in the Universe in its own way. There is a strict order in the universe, none of the planets or stars will go out of their way, out of their orbit and not collide with one another.
The word "cosmos" means the word "order, order."
Aircraft that are launched into Earth's orbit are called artificial satellites (AES). They are designed to solve applied and scientific problems. According to international agreement, a satellite is a spacecraft that has completed at least one complete revolution in the Earth's orbit. If not, then it is considered a rocket probe that takes measurements on a ballistic trajectory. The probe is not registered as a satellite.
First artificial satellite
The artificial satellite of our planet, which became the first man-made celestial body created by man, was launched into orbit in 1957 (October 4) in the Soviet Union. This is the result of the country's achievements in the field of rocket technology, automatic control, electronics, celestial mechanics, computer technology and other branches of science. Thanks to this satellite, for the first time measurements of the density of the upper atmosphere, studies of the propagation characteristics of radio signals in the ionosphere were made. The main technical and theoretical solutions and calculations for launching an artificial Earth satellite into orbit were tested. It was a fantastic breakthrough of mankind in the exploration of outer space, and it laid the foundation for the great Space Age of all mankind. And the palm rightfully belongs to the USSR.
Achievements of different countries
The United States was quite a bit behind the USSR and four months later, on February 1, 1958, launched its first man-made satellite called Explorer-1 into Earth's orbit. Some other countries of the world lagged behind the pioneers. Subsequently, the following states independently launched artificial satellites into orbit:
- France in 1965 November 26 (satellite "A-1"),
- Australia in 1967 November 29 (VRESAT-1 satellite),
- Japan in 1970 February 11 (Osumi satellite),
- People's Republic of China in 1970 April 24 (satellite "China-1"),
- Great Britain in 1971 on October 28 (satellite "Prospero").
The international cooperation
Some artificial satellites, which were manufactured in Italy, Canada, Great Britain, France and other countries, starting from 1962, were launched into the Earth's orbit using American rocket carriers. International cooperation is quite widely used in the practice of space research. Thus, as a result of scientific and technical cooperation between the countries of the socialist camp, a number of satellites were launched. The first of these was Interkosmos-1, which was launched into orbit on October 14, 1969. By 1973, over 1300 satellites had been launched various types and appointments. Of these, about 600 satellites are Soviet and more than 700 American and other countries of the world, including manned spacecraft-satellites and crewed space orbital stations.
It is difficult to overestimate the achievements of science in the field of space exploration of the Earth. After all, with the help of artificial satellites, all kinds of research work are carried out. Depending on the tasks that are capable of solving satellites, they are divided into applied and research. There are also manned and unmanned satellites. Both of them serve for numerous studies of the planet itself, celestial bodies and infinite outer space.

The course of educational activities
(The teacher and children enter the hall and become in a circle)
Educator. Guys, we recently celebrated the holiday on April 12 - Cosmonautics Day. Today we will travel into space and learn a lot about the planets of the solar system and astronauts. Do you want to become astronauts? (Children's answers) I invite you to join hands and build our ship. Fasten your seat belts, close your eyes and imagine that our ship is taking off. (Space music sounds). Open your eyes, we found ourselves in outer space. (Children sit on chairs).
Educator. Children, how long do you think people have learned about space? (Answers of children). In the distant past, people had a wrong idea about the cosmos and about our planet, the stars seemed to them like small luminous points, and the earth was presented as a flat disk, and that it was standing on elephants and a turtle. Were our ancestors right? (Answers of children). Tell me what you know about space and our planet. (Answers of children).
Educator. Now listen to my story. (The presentation starts) People have long wanted to know what space is, what kind of bright dots shine above their heads at night. Scientists have invented a special device - a telescope, which, having looked, it was possible to consider not only stars, but also planets. But to find out if there is life in space, it was necessary to fly into space.
Almost a hundred years ago, a simple teacher Konstantin Eduardovich Tsiolkovsky lived in the city of Kaluga (slide). He is called the father of astronautics. It was thanks to his scientific work that mankind was able to rise to previously unseen heights and enter outer space. In 1903, Konstantin Eduardovich's first work on the theory of rocket flight appeared in the journal Nauchnoye Obozrenie. Year after year, Tsiolkovsky continued to develop rocket technology. He imagined such a rocket that would "remove from the Earth, wander between planets, stars, visit planets and their satellites, return to earth."
His work was continued by students - scientists under the guidance of designer Sergei Pavlovich Korolev, who built the first rocket (slide). First, they made the first artificial Earth satellite and launched it into low Earth orbit. And four years after the launch of the first satellite, a man went into space.
Who was the first to fly?
In 1957, the first "cosmonaut" was the dog Laika (slide), with which mold fungi, tradescantia, flies and mice were sent. The flight was successful. In 1958, they increased the size of the rocket and sent two like dogs: Belka and Strelka (slide). They also returned safely to Earth. And the scientists decided to fulfill their cherished dream - to send a man into space!”
Who was the first astronaut?
That's right, Yuri Alekseevich Gagarin. On April 12, 1961, the dream of mankind came true. For the first time in history, a spacecraft with a man on board was launched into Earth's orbit. That was very important event for the whole world. The whole world wanted to see the first cosmonaut of the planet. Gagarin visited dozens of countries. Everywhere he was greeted with delight, because he truly became a celestial (slide).
So a new profession appeared on the planet earth - an astronaut.
What was the name of the first female astronaut? (Valentina Tereshkova)
But it's not easy to become an astronaut. What do you think, what kind of person can get into the cosmonaut corps? (Answers of children).
Phys. minute. After hard work, astronauts must rest. Let's have a rest and play the game "Cosmonaut".
One or two, there is a rocket. (Children raise their hands up)
Three-four, takeoff soon. (Spread hands to sides)
To reach the sun (Circle of arms)
Cosmonauts need a year (He takes his cheeks with his hands, shakes his head)
But dear, we are not afraid (Hands to the sides, body tilts to the right - to the left)
After all, each of us is an athlete (They bend their arms at the elbows)
Flying over the earth (Spread their arms to the sides)
Let's say hello to her (Raise hands up and wave)
(Children sit on chairs).
Educator. Our flight continues on. All of you know how to listen carefully and answer questions, like to learn new and interesting things. Today we will learn a few secrets of space. But first guess the riddle:
It warms the whole world
And does not know fatigue
Smiling at the window
And everyone calls him ... (Sun)
Educator. Guys, do you think the sun is a planet? (Answers of children). The sun is actually a star, just like the ones we see in the night sky. But why do other stars appear to us in the night sky as small dots? (children's answers)
Educator. We see the stars in the night sky as small because they are very far away from us, but they are as hot as the Sun. And the Sun is closer than other stars to our planet.(The teacher sticks an image of the Sun on the layout of outer space)Children, describe the Sun to me. What color is it, what shape is it, what does it look like? (children's answers)
Educator. The sun in space is not alone, it has a family. The family of the Sun is called the Solar System. These are planets. Each planet has its own name and track - the orbit along which the planet moves. Now your friends will tell about each planet.
(Children put on hats with the image of the planets and talk about them. The stories are accompanied by a slide show.)
1st child. Mercury - the planet closest to the sun, so the air temperature there is very high. The surface of Mercury is rocky, there is neither water nor air.
2nd child. Venus is the second planet from the Sun. She is shrouded in clouds. Thunderstorms rage there day and night, and the atmosphere consists of poisonous gases.
3rd child. Earth is the third planet from the Sun. This is the only planet suitable for life. It contains oxygen and water. The Earth has a satellite - the Moon. A model of the earth, reduced many times, is called a globe.
4th child. Mars is the fourth planet in the solar system. It is called the "red planet" because it is made up of red stone. Before scientists knew that there was no life there, people believed that "Martians" lived there.
5th child. Jupiter is the fifth planet from the Sun and is considered the largest planet. It is composed of gases and is so large that all the planets could fit on it.
6th child. Saturn is the sixth planet in the solar system. Saturn is surrounded by rings of ice and dust.
7th child. Uranus is the seventh planet in the solar system. This is the only planet that revolves around the Sun, as if lying on its side.
8th child. Neptune is the eighth planet. Neptune is farthest from the Sun, so it is very cold there and strong winds blow. The planet's atmosphere is blue.
Educator. So we learned which planets revolve around the sun. And that each planet has its own path called an orbit.
Each planet has its own path.
It is impossible for her, believe me, to turn off the orbit.
Our planets revolve around the sun.
They are all warmed by the Sun in different ways.
Educator. And now we will play with you the game “Place the planets correctly” and check whether you have carefully listened to the stories of your friends about the planets.
On the floor are numbers from 1 to 8. In the center is a yellow circle. The child "Sun" is selected, the children put on hats with planets, music sounds, the children run around the "Sun". As soon as the music stops playing, the “planet” children should stand on the number that indicates the place in the solar system.
The round dance of the planets is spinning.
Each has its own size and color.
For each path is defined,
But only on Earth the world is inhabited by life. (Kids are playing.)
Educator. Our flight ends, we must return to Earth. Let's remember what we talked about today. Continue suggestions:
Cosmonautics Day is celebrated...
The first cosmonaut...
The first female astronaut...
The planet where people live...
The sun and planets are...
You all did a great job today, well done! I want to know if you enjoyed our trip. Look, I have a picture of the solar system. (The sun and planets are on the drawing paper) It seems to me that something is missing here. (Stars). Let's put stars in the solar system. If you liked our trip, glue a star, if not, a space rock. (Children do the task)
This is where our journey ends, I hope, maybe one of you, when you grow up, will also become an astronaut. Goodbye!

LESSON PROCESS
I. "Earth is our home in the universe", "Natural Satellite of the Earth"
1.1. The teacher's story.
Do you guys know what our planet is like?
In ancient times, people believed that the Earth is huge and flat, like a pancake or like a plate, and you can get to the edge of the Earth. There were daredevils who dreamed of getting to this region and seeing what was there, on the edge of the Earth, and whether it was possible to fall from it. They set out on foot, or on horseback, or by ship.
Those people who traveled on foot or on horseback, sooner or later got to the big water - the sea or the ocean - and believed that their journey it's finished: here it is, the edge of the Earth, and there is nothing further than water. But there were also those who, having reached the seashore, transferred to the ship and continued their journey. It was these navigators who made sure that, setting off on a journey from some place and always moving in the same direction, for some reason they return to where they started the journey.
"Why is this happening?" people thought. Yes, because, suddenly someone realized that the Earth is not flat, like a pancake. No, it's round like a ball.
1.2. Collaboration with children
Here we have small balls. Take them. And we also need markers. Now imagine that you are travelers and each of you is standing on top of the ball. Put the tip of the marker there. Now your path will go down all the time. Move the marker down the ball and turn the ball as the marker moves. If you gently move the felt-tip pen in one direction, you will soon find yourself at the same point where you started your journey.
This is how our travelers were convinced that the earth is a ball.
1.3. The teacher's story
What then surrounds the Earth? And it is surrounded by a huge space, which is called outer space, or outer space.
Space- this is a huge space without end and edge that surrounds our planet. This space is not empty, it is filled with various cosmic bodies - stars, planets and their satellites, comets and meteorites.
AT space space there is a natural and only satellite of the Earth - the Moon.
The Moon is a natural and only satellite of the Earth, located at a distance of 384 thousand kilometers from it. The moon is a cold, rocky spherical body with a solid surface, without atmosphere and water. The origin of the moon has not yet been definitively established. Its most probable age is about 5 billion years.
(Slide 3)
1.4. Conclusion "What is the Earth
So what is Earth?
Earth is the planet on which we live.
From space it looks like a beautiful blue ball.
Most of the Earth is covered by the blue water of vast oceans. White spots are clouds, snow and ice. Huge expanses of green-brown color are Land - spaces covered with stone and soil.
Earth is the only inhabited planet known to us. People, plants and animals can live on Earth because it is neither too hot nor too cold. Earth has water to drink and air to breathe. They are essential for all living organisms to survive.
(Slide 4)
II. The concept of a satellite
There are artificial and natural satellites.
Natural Satellite - a celestial body circulating along a certain trajectory (orbit) around another object. (for example, the moon)
artificial satellite - space aircraft , moving in orbit around a celestial body. (device launched in space from earth)
On October 4, 1957, the first artificial satellite of the Earth, the Soviet spacecraft Sputnik - 1. Satellite code designation - PS-1 (The simplest Sputnik-1).
(Slide 5)
November 3, 1957 at half past six in the morning Moscow time on a Soviet ship "Sputnik-2" in space the first animal was launched - the dog Laika (the first dog - astronaut that circled the earth. At that time, Laika was about two years old.
(slide 6)
III. The first person in outer space
3.1. Conversation with children
Guys! Do any of you know who was the first person to fly into space, first astronaut?
On April 12, 1961, an unexpected news: "Man in outer space! Russian, Soviet!. The centuries-old dream of people to fly to the stars has come true.
On April 12, 1961, Yuri Gagarin became the first person in world history to fly into space. On a sunny morning, a powerful booster "East" with the ship "Vostok-1", on board of which Gagarin was, was launched from Baikonur Cosmodrome.
(slide 7)
Starting from April 12, 1962, the day of Gagarin's flight to space was declared a holiday astronautics.
Now astronauts often fly into space we are already used to it. But when in space flew the first astronaut, people of all peace experienced amazement and delight.
3.2. The teacher's story about the memories of Yuri Gagarin during flight
There has never been such a miracle -
Into the cold Space
A man is running!
name Gagarin,
Yuri Gagarin
In the memory of people entered forever.
His exploits are legendary!
The world is grateful to the brave
Their homeland is proud of them!
Yuri Gagarin took a seat in the cockpit, the command sounded "Start!" "Go!"- the voice of the first astronaut. The engines roared, the rocket took off from the Earth and went into the sky.
What did Gagarin experience in the ship? What did he see through the windows?
Listen to an excerpt from his memoirs.
“When the ship went into orbit, weightlessness appeared. I pulled myself away from my chair and hung between the ceiling and the cabin floor. Everything around became easier.
"Earth" asked what I see, and I said that mountain ranges, large rivers, large forests, spots of islands, coastal edge of the seas are clearly visible. More than an hour, namely 108 min, lasted the first human flight in outer space. During this time the ship "East" circled the entire globe and landed in a precisely specified area.
Gagarin successfully landed in the Saratov region, not far from the city of Engels.
(slide 8)
The ship landed on a plowed field. And then an interesting episode occurred, about which Yuri Gagarin later spoke.
“Having stepped on solid ground, I saw a woman with a girl standing near a spotted calf and watching me with curiosity. Went to them. They walked towards. But the closer they got, the slower their steps became. I was still wearing the bright orange suit, and its unusual appearance must have frightened them. They have never seen anything like it…”
(slide 9)
IV. What are artificial satellites for?
Ship "East" only once circled the earth. And modern space the station is in space for many years. This is real space house, wherein astronauts live for many months.
People began to create such stations for long flights in space.
At orbiting scientific stations astronauts different countries conducting earth exploration and outer space.
Sometimes they leave the station and go out into the open space.
"Wings" space stations are solar panels. They are "catch" sun rays and turn them into electricity. And the current illuminates, heats the station and feeds all scientific instruments.
(slide 10)
astronauts the sun and stars are observed through the porthole, the Earth is photographed. They have to melt and weld metal, test strength various materials. astronauts grow various plants at the station to find out how they feel in outer space.
You already know that our planet has a natural satellite. What is it called?
Faithful companion, decoration of nights,
Additional lighting.
Of course we confess must:
It would be boring for the Earth without... (Moons)
But man was able to create and run in space artificial earth satellites.
What kind of relative of the moon is there,
Nephew or granddaughter
Flickers between the clouds?
Yes, it's a satellite!
Here are those times!
He is the companion of each of us
And in whole - the whole earth.
The satellite was created by hands,
And then on a rocket
Delivered to these.
When this happened, the radio stations peace interrupted their transmissions to tell the most important news.
Russian word "satellite" included in all languages peace. Right now in outer space there are always many artificial satellites. Why are they needed?»
Communication satellites carry out television transmissions to remote corners of the Earth. Their help is needed for radio and telephone communications.
Here is the starry sky! What can be seen on it?
The stars there shine with a distant fire!
Are the stars shining in the sky?
Not! Planets roam among the stars!
How do they wander like that? Roads do not know?
Not! It looks like they're wandering!
All of them are the Sun's big family.
And under the influence of his attraction
Always making circular motions!
And with them my planet
The one called the planet "Earth"
The one where you and I live!
People have already taken their first step in space: they built spaceships, which can rise from the surface of the earth in space.
People have flown to the moon and even traveled on its surface.
Now people:
Explore the entire solar system;
launch spacecraft to planets, preparing rockets and astronauts to travel to them. And here they are waiting for a lot of amazing discoveries.
Who knows, guys, maybe one of you will be able to fly to space. To do this, you need not be afraid to dream and fantasize, and also be able to go towards your goal, overcoming all obstacles.
