stars, an interstellar medium of gas and dust, and

dark matter.Typical galaxies range from dwarfs with as few as ten million stars up to giants with one trillion stars. Galaxies can also contain many multiple star systems, star clusters, and various interstellar clouds.

the other celestial objects: the eight planets, three dwarf

planets, and billions of small bodies: asteroids, comets, meteoroids, and interplanetary dust.

of the Solar System. The Earth, other planets, asteroids,

meteoroids, comets and dust orbit the Sun. Energy from the Sun supports almost all life on Earth.

plasma. Stars dominate the visible universe and they group

together to form galaxies. The nearest star to Earth is the Sun, which is the source of most of the energy on Earth.

and exhibits a coma and/or a tail, which itself is a minor body composed of rock, dust, and ice. Very few are noticed by the general public. Such comets are often designated Great Comets. They are: Halley's Comet, Comet Hale-Bopp, Heaven's Gate, Comet Kohoutek, Comet West, Comet Hyakutake, Comet McNaught, and Halley’s Comet.

particle of debris in the Solar system. The visible

path of a meteoroid that enters Earth's (or another body's) atmosphere is a meteor, commonly called a "shooting star" or "falling star". Many meteors are part of a meteor shower.

Sun. Its diameter is 12,760 km. Means distance from

the Sun is 150 millions of kilometers. The only natural satellite is the Moon.

and the fifth largest moon in the Solar System.

The average centre-to-centre distance from the Earth to the Moon is 384,403 km. The Moon has a diameter of 3,474 km. The Moon makes a complete orbit around the Earth every 27.3 days.

in the level of the sea. The moon and

the sun together pull the sea. In some parts of the world the difference between ‘high tide’ (when the sea is very near to the land) and ‘low tide’ (when the sea is far away from the land) is very big. This is very important for ships.

On that day, the Union of Soviet Socialist Republics

launched Sputnik 1, the first artificial satellite to circle the earth. Its capsule weighing 83.6 kg went into Earth orbit carrying a radio transmitter whose “bleeps” (pips) were received on the ground.

a capsule on board Sputnik 2. It contained an air supply, food and water, together with instruments for recording her heartbeat, breathing and blood pressure.
Data were transmitted back to scientists on Earth.

safely returning to Earth. They were accompanied by a grey rabbit, 42 mice, 2 rats, flies and a number of plants and fungi. All passengers survived. They were the first Earth-born creatures to go into orbit and return alive.

Soviet cosmonaut circled the earth on April 12, 1961. From blastoff to landing, his trip around the earth lasted 1hour and 48 minutes. The news about space flight of the Soviet cosmonaut immediately flew over the world.

group flight with V.Bykovsky, the spaceship “Vostok-6”piloted by Tereshkova made in 70 hours and 41 minutes 48 circuits around the earth, covering a distance of about 2 million kilometers.

Armstrong and Edwin Aldrin.
Armstrong landed the lunar module ‘Eagle’ on the surface of the Moon at 4:17:42 p.m. July 20, 1969. He described walking on the Moon as ‘one small step for a man, one giant leap for mankind’.

flight of the U.S. and Soviet space programs. The

mission took place in July 1975. For the United States of America, it was the last Apollo flight, as well as the last manned space launch until the flight of the first Space Shuttle in April 1981.

1986. It was designed to stay in orbit for

long periods for scientific experiments to be carried out on board.

there is an opposite reaction. Modern rockets have liquid

fuel and something to help it burn (an oxidizer). This makes a powerful exhaust through the back of the rocket and pushes the rocket up.

Tsiolkovsky’s idea of

spaceship was based on the use of liquid fuels. His calculations were used in modern theory of cosmonautics and practical space travel.

He was the chief constructor of the first

Then followed rockets to the Moon, Mars, Venus.

USSR launches first satellite, Sputnik 1.
Yuri Gagarin (USSR)

is the first man in space.
USA launches first communications satellite.
Valentina Tereshkova (USSR) is the first woman cosmonaut.
Apollo 11 astronauts Neil Armstrong and Edwin Aldrin (USA) land on the Moon.
USSR sends two probes to Mars.
USA and USSR cooperate in space; Apollo and Soyuz craft dock (link) in orbit.
Pioneer spacecraft (USA) leaves solar system.
The Soviet space station Mir is launched into space.

about space travel.
Sergei Pavlovich Korolyov was the chief constructor of the first telephone.
On October 4, 1967 the Union of Soviet Socialist Republics launched Sputnik 1, the first artificial satellite to circle the earth.
Yuri Alekseyevich Gagarin, a Soviet air force pilot, was the first human to travel to Mars.
Valentina Tershkova was the first woman-cosmonaut in the world.
Alexei Leonov went outside wearing a space suit connected to the capsule by a line which also carried his oxygen supply, becoming the first person to “walk” in space.
