People have been studying space since very old times. They divided stars into groups – constellations giving them names: Orion, Taurus, Leo, Virgo, Aquila, Lyra, Vega, Andromeda, Cassiopeia, Draco, Ursa Major

Слайд 1EXPLORING SPACE FROM ANCIENT TIME TO NOWADAYS.
Space Exploration from Ancient

Times to Nowadays

Слайд 2People have been studying space since very old times. They

divided stars into groups – constellations giving them names: Orion,

Taurus, Leo, Virgo, Aquila, Lyra, Vega, Andromeda, Cassiopeia, Draco, Ursa Major and Ursa Minor and others. Some of these constellations appear to rotate around the North Pole Star.

Слайд 3 Just over 400 years ago, Galileo invented a

device that allowed viewers to see very distant objects as

if they were nearby (the first telescope). Since that time astronomy started developing rapidly – people began making discoveries.

Слайд 4Then August, 1960 dogs Belka and Strelka were sent into

space on board “Sputnik 5”. The flight lasted more than

25 hours, orbiting the Earth 17 times.

Then the era of space flights started in the 20 century.
October, 1957, Laika, a Soviet Space dog was the first animal to orbit the Earth on board “Sputnik 2”.

Then August, 1960 dogs Belka and Strelka were sent into space on board “Sputnik 5”. The flight

Слайд 5Yuri Gagarin was the first human to journey into outer space

when his Vostok spacecraft completed an orbit of the Earth on 12 April 1961. The flight lasted

108 minutes.

Yuri Gagarin was the first human to journey into outer space when his Vostok spacecraft completed an orbit of the Earth on 12 April 1961.

Слайд 6Conditions on board a space vehicle orbiting Earth greatly differ

from those on its surface – everything on board a

ship is in the state of prolonged weightlessness. What can weightlessness be used for? Many well-known processes go on differently due to the absence of weight.

Conditions on board a space vehicle orbiting Earth greatly differ from those on its surface – everything

Слайд 7The burning candle. There have been experiments in space to

this effect, the flame reacts to gravity and burns up

on earth. In low to no gravity places, the flame makes a more spherical shape.

Слайд 8New materials can be obtained, the components of which would

immediately separate on Earth because of convection. In case of

metals, glasses or semiconductors, they can be cooled down to the solidification point even in space and then brought back to Earth. Such materials will possess quite unusual qualities.
