History
We have been inventing and exploring things since day one.

Many of these things that we discovered or invented we thought
would never be possible in earth’s life time.

During the cold war space war became too much critical.


The exploration of space began , with the launch of the first
artificial satellite, Sputnik 1, which the Soviets sent into orbit in
1957.

This was a monumental achievement in the history of
space exploration and by the Soviet space exploration
program.


Globally, 43 countries now have their own observing or communication satellites in
Earth orbit.

Space Exploration
 Soviet cosmonaut Yuri Gagarin became
the first human in space in 1961.




 On July 20, 1969, Astronaut Neil
Armstrong took “a giant step for mankind”
as he stepped onto the moon.
Space Exploration
Extremely dangerous
             Counter Argument

The exploration of space is fraught with peril.


Since we first started putting humans into
space, there have been accidents, and many
people have died.

However, as time and tragedy has shown us,
dangers still exist today.


Manned missions to space impose a huge
amount of risk on the astronauts who travel to
space.
A launch    Highly explosive fuel,
            Poor weather,
            Malfunctioning equipment,
            Human error
             Even

Once in flight  Floating debris,
                Meteoroids,
                Electromagnetic radiation




Re - Entering to earth’s environment has also its dangers
             As proven by the Columbia disaster.
1967                   1986                2003


   3 astronauts of     7 astronauts died    7 astronauts died
Apollo 1 died during    when the space       when the space
  training exercise.   shuttle challenger   shuttle challenger
                        exploded shortly     Columbia broke
                          after launch.      apart during re-
                                                  entry.
Significantly more people have died in space related
accidents, before craft have even left the ground

         in October 1960, 91 people were
killed when a booster rocket exploded at a
space centre in Kazakhstan in the USSR.
         in 1980, 50 technicians died when
a Vostock booster rocket exploded while
being refueled.

The space shuttle has failed only three
times in its 113 launches

But if we apply statistics
   Space Shuttle 1  10,000 flying hours
   US aircraft   1  37,000 flying hours

Thus space travel is cited as more
dangerous than just about any other form
of getting around.
Too Counterexpensive
              much Argument

The cost of space exploration is too much.

Space exploration involves both astronomy and
space technology. It requires a huge amount of
money to be spent on the journey to space.


Humans in space require life support in order to
survive. Because of these extremely complex
systems need to be installed in the spacecraft.


Humans need to be brought back alive after the
mission has been completed. This will also add
complex systems to the spacecraft.
Too much expensive

In 1990s us spent about $100 billions on
the Apollo Moon Program.

This money could provide

          a year of health care for
           1,65,000 people
                    OR
          Electricity for 8,30,000 homes
                    OR
          Build 2200 housing units
Too much expensive

Spin Supporting Argument
                   - off Technology

 when we watch satellite TV,
 when we consult the weather forecast,
 when we pick up the phone to contact
   someone
 when we access the internet,
 when we check our in car navigation system for
  routing information.



  What is Spin off Technology?

  Since 1976, more than 30,000 applications of
  space technology have been brought down to
  earth to enhance our everyday life.
kidney dialysis and the new artificial heart
have been based on technology found in
space shuttle



Programmable Heart Pacemakers were first
developed in the 1970s using NASA satellite
electrical systems.



Image processing used in CAT scanners and
MRI technology in hospitals worldwide
came from technology developed to
computer improved pictures of the moon
for the Apollo programs.


Infrared hand-held used cameras to observe
blazing plumes from the Shuttle have
helped fire-fighters point out hot spots in
brush fires.
Joystick
 evolved from  Apollo Lunar Rover
 Used for  Computer Games,
             Cranes,
             Mining Trucks,
             Underwater unmanned vehicles


The Fisher Space Pen
 This Pen was developed for use in space .
 Benefits  Cool
           You can lie in bed and write
            upside down with this pen.
Curiosity Supporting Argument
          of humankind
  Well, space is there, and we're going to climb it, and
 the moon and the planets are there, and new hopes for
 knowledge and peace are there.

  we look out, and wonder, and explore.

  The desire to know what lies beyond current
 knowledge, is one of the our noblest characteristics

  For centuries and still now, the success of humans is
 the ability to be curious and explore until the limit.

  Curiosity of mankind make them to
 explore space.

  Without curiosity, the human race might
 still be in the ancient “Stone Age”

  The evidence that has been gathered supporting
 interesting information has just fuelled this curiosity.
Curiosity of humankind

 No-one can deny the sense of wonder, when for the
 first time a new man-made star (space flight) rose in
 the sky and when Neil Armstrong first stepped onto
 the moon.


In addition, mankind also want some answers to
the most fundamental questions like,

           Are we alone?

          Are there other forms of life besides
           those on earth?

         Are we able to live on any other planet?



This is one of the things that makes life worth living.
More Oppertunities
              Supporting Argument

that micro gravity semiconductor materials can
produce chips as much as a thousand times more
powerful than anything now available




pharmaceuticals produced in space with zero gravity
have purities far higher than any produced on Earth




There is an element known as Helium 3 that is
found on the moon and could power the world for
at least 1,000 years when we are able to use it.
Space Exploration
Conclusion
 Space exploration is the key to the future and we will reap the rewards
of this necessary investment of money and resources.

 Researches and technologies about space exploration are very
important for humanity.

 Without risk, we remain in our caves, never daring to see what lies
beyond our immediate sight


 The money we are spending now on space program will help in the long
run.


 It is the main thrust of humanity’s future dreams which expands
their limits as new projects accomplished.


 Despite the fact that space exploration projects need huge amout of
money and labour and also time, it can not be totally stopped.
My Recommendation

 Future space launch systems will be designed to reduce costs
and improve dependability, safety, and reliability.


 They should develop new technology that is more useful


 Useful technology should be commercialised to enhance people life.



 They should spent money also on other require field.
