Spaceflight, Space flight means the use of space technology to achieve the flight of spacecraft into and through outer space. A space flight begins with a launch
which provides the force to push from the gravity which sends the space craft
to the surface of the earth.
People began travelling to space in 1961 in small spacecrafts which are
called capsules, which were launched from earth by using powerful rockets.
How do humans survive
There is no availability of oxygen, water
and many other human needs .So all the air craft with crew carry a life –
support system. This supplies air to breathe. This system also includes the
equipment to keep the air at comfortable temperature. This system also removes
carbon dioxide and odours.
ALLOWING FOR SPACETRAVEL (HUMAN FLIGHT):
human flight was launched by the Soviet
Union on 12 April 1961 as a part of the Vostok program, with cosmonaut Yuri Gagarin aboard. The first human flight is made by
Soviet Union (Russia) in 12 April 1961 and named as Vostok1.
first human to the Moon
crewed missions only took place in 1973 and 1974; first American space

ENTERTAINMENT AND FREE
TIME IN SPACE:
The astronauts can bring some
of their own belongings with them. They can spend their leisure time in the
same way that they are spending on Earth by reading their favourite books,
listening to music, etc..
Also, since the Earth and stars they’re able to see
from the Space Shuttle’s windows are so beautiful, the astronauts can spend
their time by enjoying the view and taking pictures of stars planets etc..
Living in space is not just doing only work and nothing to play.
Astronauts like to have fun, too. If you’re staying on the International Space
Station for a few months, it is certainly okay to look out the window, play
with your food or tease your crewmates once in a short time. Fun is an
essential component to the quality of life.
WHAT IS THE OUTER SPACE LIKE?
Ø We usually don’t notice, but also air have
some weight, and it is held onto the surface by the earth’s gravity.
Ø Higher than 400 km above
the ground, where the International Space Station (ISS) is flying, there is
almost no air. The state where no air is present is called as vacuum. And Space
is a vacuum.
Ø Generally, the altitudes of 100 km or above are
considered as outer space. Where humans can’t live without spacesuit.
Ø In the higher elevations, the amount of air is
less. That is why the air becomes less as higher as you go up.
Ø In a vacuum, humans cannot live without wearing a
Ø As the space a is vacuum there is no air to
breathe in Space.
