1. Space Exploration
By Gina Wike

2. Hubble Space Telescope
 Hubble Space
Telescope is an optical
telescope that is in
space. It was put into
space in 1990 by the
space shuttle
Discovery.

3. Hubble Space Telescope
 The advantage of
having a telescope in
space is that we do
not have to look
through Earth’s
atmosphere—pictures
are much better
because of this.

4. Hubble Space Telescope
 When Hubble was first
put into space it did
not work properly
because of an error in
the shaping of the
mirror; it was repaired
by astronauts from the
Endeavor in 1993.

5. Satellites
 A satellite is any object that revolves
around another object.

6. Satellites
 When an object enters space, it will travel
in a straight line until the Earth’s gravity
pulls it back toward Earth.
 Because the satellite is traveling forward
and falling toward Earth at the same time,
the satellite will travel in a curved path
around Earth known as an orbit.

7. 2 Types of
Satellites-
Natural & Artificial
There are both natural and artificial
satellites.

8. Natural Satellites
 The moon is a natural
satellite.
 It orbits the Earth.

9. Sputnik- 1st Artificial Satellite

10. Sputnik 1
 Sputnik was
launched by the
Soviets in 1957,
marking the
beginning of
space
exploration.

11. Space Probes
 A space probe is an instrument that gathers
information and sends it back to Earth.
Space probes travel far into space.
 Examples: Voyager I and II (didn’t land on a
planet), Viking (did land), Galileo (dropped
probe onto Jupiter)

12. Space Program &
Important People
Yuri Gagarin
&
President Kennedy

13. Yuri Gagarin
 In 1961, Yuri Gagarin became the first
human in space.

14. President Kennedy
 President Kennedy
called for the US to
put the first man on
the moon by the end
of the decade.

15. Projects that led to man on the moon
 Project Mercury
 Project Gemini
 Project Apollo

16. Project Mercury
 Project Mercury- orbit a crewed spacecraft
around Earth and bring it back safely

17. Alan Shepard
 1961- Alan Shepard
became 1st US citizen
in space
 Was not on Apollo 13
because of an ear
infection
 Apollo 14-oldest man on
moon (47)
 Hit golf balls on moon

18. John Glenn
 1962- John Glenn
became the 1st US
citizen to orbit the
Earth

19. Project Gemini
 Project Gemini- two teams of astronauts
met and connected

20. Project Gemini

21. Project Apollo
 Project Apollo- July
20, 1969 Apollo 11
landed on the moon
 Saturn V that
launched Apollo 11

22. Project Apollo
 Neil Armstrong
was the first man
to walk on the
man.

23. Neil Armstrong
 “That’s one step
for a man, one
giant leap for
mankind.”

24. Apollo 11- Edwin Aldrin
 Edwin Aldrin was the
2nd man to walk on
the moon. He and
Armstrong explored
for 2 hours.


25. Apollo 11- Michael Collins
 Michael Collins
remained in the
Command Module.
 A total of 6 lunar
landings brought back
2000 samples of moon
rock. The program
ended in 1972.

26. Space Shuttle
 A space shuttle is a
reusable spacecraft
that transports
astronauts, satellites,
and other materials to
and from space.

27. Space Shuttle
 At launch, the space
shuttle orbiter stands
on end and is
connected to an
external liquid-fuel
tank and two solid-fuel
booster engines.

28. Space Shuttle
 When the shuttle
reaches an altitude of
about 45 km, the
emptied solid-fuel
booster rockets drop
off and parachute
back to earth. They
are recovered and
reused again.

29. Space Shuttle
 The larger liquid fuel tank eventually
separates and falls back to Earth. It is not
recovered.

30. Space Shuttle
 Once the space
shuttle reaches
space, it orbits
Earth.

31. Space Shuttle Landing
 At the end of a mission, the space shuttle
orbiter glides back to Earth and lands like
an airplane. The parachute slows it down.

32. Space Stations
 A space station has
living quarters, work
and exercise space,
and all the equipment
and support systems
needed to live and
work in space.

33. Skylab
 Skylab was a space
station put up in 1973.
In 1979 it was
abandoned and fell
back into earth’s
atmosphere and
burned up

34. Skylab Launch

35. Skylab Launch

36. Mir
 Mir was a Soviet
space station.

37. International Space Station
 International Space
Station serves as a
research lab for
several countries.
 Permanent crew
 Scientists on Earth
have almost instant
access to experiments
and can modify when
needed
