        We live on a small blue planet called EARTH. It has a surface of liquid water and rocks and is 

surrounded by a blanket of air called Atmosphere. SPACE begins at the top of the Atmosphere.It is an 

unimaginably vast, silent, and largely empty place. In Space, there is a vacuum, but it has many 

amazing properties.

                                                              

• THE EDGE OF SPACE.

    Earth's atmosphere does not end suddenly - it goes gradually thinner and thinner as you travel up 

from the ground. Most of the experts agree that outer space starts at a Height of 100 KM[62 miles].

Yet even above this height, there is a layer of very thin air called the EXOSPHERE. 

Hydrogen and other Light gases are slowly escaping into Space from this outmost part of Earth's 

atmosphere.

•              Anything that travels through space at a steady speed is weightless. This why things inside a spacecraft floats and astronauts are able to lift huge Satellites using just their hands. The weightlessness disappears if the spacecraft either slows down or speeds up.

•          A  Person who stepped out into space without a protective suit would quickly die. But would still have around 10 Seconds to reach safety before losing consciousness.
