INTRODUCTIONHistory of space• In 350 BC, Greek philosopher ‘Aristotle’ suggested

that nature abhors a vacuum, a principle that became known as the ‘horror vacui’.

• The first professional astronomer to support the concept of an infinite universe was the Englishman Thomas Digges in 1576.

• In the 17th century, astronomers pointed a new device called the telescope at the heavens and made startling discoveries.

• But the years since 1959 have amounted to a golden age of solar system exploration.

• The term outer space was first recorded by the English poet Lady Emmeline Stuart - Wortley in her poem "The Maiden of Moscow" in 1842.

• The shorter term space is actually older, first used to mean the region beyond Earth's sky in John Milton’s Paradise Lost in 1667.

• Outer space is the closest natural approximation of a perfect vacuum.

Outer space• Space is every thing in the universe that lies

outside the earths atmosphere .• At the distance between stars are

unimaginable• It has no air to scatter the light• A more accurate definition of the term

"space" would be the continuous extension in all directions in which all matter exists.

First Dog in Space

• LAIKA was the first dog sent into orbit around the Earth.

• Sputnik 2, Russian, November 3, 1957 • Laika was originally thought to have

survived in Earth orbit for four days, dying in space when the batteries to the cabin over-heated.

• In 2002, we realized that Laika died 5 to 7 hours into the flight, from overheating and stress

First Cosmonaut

• Colonel Yuri Alexeyevich Gagarin• March 9,1934 - March 27, 1968• Soviet human in space• Gagarin piloted the Vostok 1 mission

which launched April 12, 1961. His flight lasted 108 minutes and orbited the Earth once. The spacecraft was recovered later that day in the Saratov region of the Soviet Union

The first rockets launched into space from Sweden

The year was 1961

First Woman Cosmonaut

•Colonel-Engineer Valentina Vladimirovna Tereshkova •(1937- ) •Soviet woman in space•She was on the Vostok 5 mission which launched on June 16, 1963, and orbited the Earth 48 times. The flight lasted 2.95 days. The spacecraft was recovered on June 19, 1963, in the Soviet Union

FIRST INDIAN WOMAN

• Kalpana Chawla, was an Indian-American astronaut and space shuttle mission specialist.

• She was one of seven crewmembers killed in the Space Shuttle Columbia disaster.

• Kalpana Chawla was born in Karnal, Haryana, India.

• Chawla joined the NASA astronaut corps in March 1995

• On January 16, 2003 Chawla finally returned to space aboard Columbia on the ill-fated STS-107 mission.

• Chawla traveled over 10.4 million miles in 252 orbits of the earth, logging more than 360 hours in space.

• Chawla earned a second Master of Science degree in 1986 and a Ph.D. in aerospace engineering in 1988 from the University of Colorado at Boulder.

MISSILES TESTED BY INDIA

• Prithvi I: SRBM (short-range ballistic missile)

• Prithvi II : SRBM• Prithvi III : MRBM(medium-range

ballistic missile)• Agni I : SRBM • Agni II :MRBM

• intermediate-range ballistic missile)• Agni V: ICBM(Intercontinental ballistic missile

)• Sagarika: SLBM (Submarine-launched

ballistic missile)• Shaurya: MRBM• Dhanush: ShipLBM• Agni III :IRBM(int

FACT ABOUT SPACE

Fact: If two pieces of metal touch in space, they become permanently stuck together This may sound unbelievable, but it is true. Two pieces of metal without any coating on them will form in to one piece in the vacuum of space.

PROS OF SPACE EXPLORATION

• Space exploration has the potential of discovering the yet undiscovered facts about space.

• It may bring about a dramatic change to our lives.

• Through the exploration of space, we may find new minerals, new precious materials.

Cons of Space Exploration

• One of the most important cons of space exploration is the money spent in the research.

• Manned missions to space impose a huge amount of risk on the astronauts who travel to space.

• Apart from the expenditure of money, a travel to space also risks the human life.
