This ppt gives you knowledge about how hard it would be to do our everyday tasks in outer space without gravity.

2. Space is bigger than the human mind can imagine it is impossible to
measure so no one knows how big space really is, All we know is that
Earth is in space and it is also home to many other planets. Space doesn’t
have a colour but some people believe that it is black.
Space is the void that exists beyond any celestial body, including the
Earth. It is not completely empty, but consists of a hard vacuum
containing a low density of particles: predominantly a plasma of
hydrogen and helium, as well as electromagnetic radiation, magnetic
fields, and neutrinos. In the space between galaxies, matter density can
be as low as a few atoms of hydrogen per cubic meter.
What is space ?
The final frontier

5. GETTING THERE…
SPACE SHUTTLE FACTS
1. Space shuttle stack weighs about
4.3 million lbs!
2. The ET is 25.4 feet in diameter and
149 feet tall
3. The SRB’s are 12.5 feet in diameter
and 154 feet tall
4. The orbiter’s wingspan is about 78
feet and it is 122 feet long. As tall
as the Statue of Liberty!

6. THE SPACESUIT
 The first astronauts to walk
in space were connected to
the spacecraft with a hose
that supplied oxygen and a
means of communication.
 Modern astronauts use a
suit that is completely self-
contained and allow them to
work outside the spacecraft
for up to 9 hours at a time
 Each suit is custom-
designed for the man or
woman who will wear it!

7. THE SPACESUIT

8. WHY WEAR A SPACESUIT?
 To explore and work in space, human beings must take their environment
with them because there is no atmospheric pressure and no oxygen to
sustain life.
 Inside the spacecraft, the atmosphere can be controlled so that special
clothing isn't needed, but when outside, humans need the protection of a
spacesuit.
 Earth's atmosphere is 20 percent oxygen and 80 percent nitrogen from sea
level to about 75 miles up, where space begins. At 18,000 feet, the
atmosphere is half as dense as it is on the ground, and at altitudes above
40,000 feet, air is so thin and the amount of oxygen so small that pressure
oxygen masks no longer do the job.
 Above the 63,000-foot threshold, humans must wear spacesuits that supply
oxygen for breathing and that maintain a pressure around the body to keep
body fluids in the liquid state.

10. SPACE FOODS
Skylab: The Skylab laboratory had a
freezer, refrigerator, warming trays, and a
table, just like at home.
Space Shuttle: Food variety
expanded to 74 different kinds of food and 20
kinds of beverages.
 Most foods are frozen, refrigerated, or
thermostabilized and will not require the
addition of water before consumption.
 Menu included: coffee, bacon squares,
cornflakes, scrambled eggs, cheese
crackers, beef sandwich, chocolate
pudding, tuna salad, peanut butter, etc.
Compartmentalized food tray!!

14. SLEEPING IN SPACE

15. SLEEPING IN SPACE
 In space there is no up or down and there is no gravity. As a
result, astronauts are weightless and can sleep in any
orientation. However, they have to attach themselves to a wall,
a seat or a bunk bed inside the crew cabin so they don't float
around and bump into something.
 On the space station there are two small crew cabins. Each
one is just big enough for one person. Inside both crew cabins
is a sleeping bag and a large window to look out in space.
Currently, space station crews have three astronauts living and
working in space for months at a time. Where does the third
astronaut sleep? If it's okay with the commander, the astronaut
can sleep anywhere in the space station so long as they attach
themselves to something.

16. TIME TO RISE AND SHINE
 When it is time to wake up, the Mission Control Centre sends
wake up music to the crew. Usually, Mission Control will pick a
song for a different astronaut each day. Sometimes a family
member will request a favourite song for their particular loved
one. Depending on the astronaut, Mission Control will play all
types of music such as rock and roll, country and western,
classical, or Russian music. However, only a shuttle crew
receives wake up music while a space station crew uses an
alarm clock.

23. RESEARCH IN SPACE
 Many of scientific
experiments can’t be
done in Earth due to
presence of gravity.
 However, those
experiments can be
done more effectively in
space.
 This is due to zero-
gravity environment in
Space.

24. SPACE RESEARCHES
BENEFITS
Researches and technologies about space
exploration are very important for humanity.
Research done is space contribute to
improving national security, the economy,
productivity and lifestyle.
Since 1976, more than 30,000 applications
of space technology have been brought
down to earth to enhance our everyday life.

25. SPACE RESEARCHES BENEFITS
 Technology - space
program technology has
resulted in more than 1,500
commercial products,
including satellite radio,
digital and satellite
television, cell phone
technology, and GPS
navigation.
 Medical - Digital hearing
aids, miniature heart pumps,
cancer detection devices,
eye surgery, and numerous
other medical and safety
devices and improvements
trace their origins to space
technology
MRI technology (brain
scanners) in hospitals
worldwide came from
technology developed in
space
Pharmaceuticals
produced in space
with zero gravity have
purities far higher than
any produced on
Earth

26. SPACE RESEARCHES BENEFITS
 Electronics: The field of electronics and computers have also
benefited from the space exploration. The astronauts have
manufactured miniature electronic parts that could only be
produced in the space during their experiments in the space
stations and space shuttles.
 Environmental: Clean & Safe Water. Water-purification
technology used on the Apollo spacecraft is now employed in
several applications to kill bacteria, viruses, and algae in
community water-supply systems.
