Space Travel
Space travel is a
form of travel in which passengers enter space, the vast region outside the
protective envelope of the Earth's atmosphere. Man’s curiosity for knowledge
has led him to explore space. Space contains the planets, countless galaxies
and milky ways. Man has been able to go to space and collect pictures of the
sun, the planets and the moon. The first man made satellite Sputnik-1 was sent
into space by Russia in 1957. Uri Gagarin of Russia became the first man to go into space. Man has landed
on the moon and he is trying to find out the existence of life on other
planets. Telecommunication, weather forecasting, radio and television
programmes etc. are all monitored by satellites in space. There are also military
stations and spy satellites in space which pose a threat of a nuclear war. This
should be avoided and scientists should work for the benefit of mankind. People
might explore the rest of the solar system and galaxy, learning
more about the nature of the universe and potentially leading to a discovery of
life beyond the boundaries of Earth.
