Title: Exploring Space!


1
Exploring Space!
  • Everything you did and did not want to know about
    how humans have explored space!

2
Way way back
  • Astronomers have been studying space since way
    way back (the ancient Greeks and Romans)
  • In 1543 Copernicus proposed the idea that the
    earth orbits the sun.
  • The earth was NOT the center of the universe!

3
Telescopes
  • Adapted by Galileo Galilei in 1609
  • Telescopes gather light and often magnify it to
    visual proportions
  • Telescopes can gather visual light,
  • or radio waves, or infrared radiation

Yerkes telescope in Wisconsin, The largest
refracting telescope in the world
4
More telescopes!
  • Some telescopes are in orbit around Earth.
  • The Hubble Telescope is in orbit and provides
    some of the clearest images of distant objects

5
Space travel
Sputnik 1 1st Satellite
  • The idea of going into space or sending people
    into space started in the 1950s
  • 1957 The Soviet Union launched the first
    satellite to orbit earth
  • 1958 The Soviet Union sent the first human into
    space

6
Race to the Moon!
  • The United States Won!
  • NASA (the National Aeronautics and Space
    Administration) created the Apollo program to try
    to reach the moon
  • July 11, 1969 the crew from Apollo 11 walked on
    the surface of the moon

7
Researching the moon
  • NASA achieved 5 more moon landing between 1969
    and 1972
  • The Apollo program helped scientists learn about
    the moons surface and interior

8
The International Space Station!
  • Space station a satellite in which people can
    live and work for long periods
  • Russia, US and 15 other nations began building
    the Intertational Space Station in 1998.
  • The first crew was in 2000
  • As big as 2 football fields
  • Crew makes observations of earth and perform
    experiments especially about gravity

9
The Space Shuttle
  • How NASA launches the ISS crew into space
  • First Space Shuttle, Columbia was launched in
    1981
  • Can be used over and over again
  • Have been launched more than 100 times since 1981

10
Unmanned Spacecraft
  • We cannot send humans to other planets
  • The trip is too long, too expensive and too the
    conditions are too harsh on many other planets
  • Carry instruments that test the compositions and
    characteristics of planets

11
Flybys
Picture the Voyager 2 took of Saturn
  • A spacecraft passes one or more planets without
    orbiting them
  • Voyager 2 was sent in the 1980s and flew by
    Jupiter, Saturn, Uranus and Neptune

12
Orbiters
Orbiter of Mars
  • Target a specific planet to study and orbit that
    planet over a long period of time
  • Data is collected and sent back to earth as radio
    waves
  • Help create detailed maps of planets

Lunar orbiter
13
Landers
  • A craft designed to land on a planets surface
  • Have been to the Moon, Venus, and Mars

14
Probes
  • A spacecraft that usually drops into a planets
    atmosphere, but only work for a short time before
    they are destroyed by conditions on a planet
  • Useful for studying the deep atmosphere of the
    giant planets like Jupiter

The Galileo probe which dropped into the
Atmosphere of Jupiter
15
Quiz Was this Spacecraft a probe, a lander, an
orbiter, or a flyby?
  • 1. Luna 1 in 1959 flew by the moon
  • 2. In 1966 Luna 9 made a soft landing on the
    moons surface
  • 3. The Galileo spacecraft in 1995 began to orbit
    Jupiter but released a ______ which studied
    Jupiters atmosphere for 1 hour before it was
    destroyed.
  • 4. Magellan in 1989 made a map of the surface of
    Venus by revolving around the planet
  • 5. The Viking 2 was sent in 1975 to Mars to roam
    the surface and search for life

16
Brief Timeline of Space
  • 1609 Galileo invents the telescope
  • 1924 An astronomer named Edwin Hubble confirms
    the existence of other galaxies
  • 1957 First artificial satellite Sputnik was
    launched by the Soviet Union
  • 1958 The National Aeronatics and Space
    Administration (NASA) is established to oversee
    the exploration of space
  • 1969 First man, Neil Armstrong walks on the moon
  • 1977 The Voyager 1 and Voyager 2 are launched to
    Jupiter, Saturn and beyond, they are now 10
    billion km away and still sending back pictures
    to earth
  • 1981 The first space shuttle, Columbia, was
    launched by NASA
  • 1992 Astronomers discover the first planet
    outside our solar system
  • 2000 The first 3 man crew was sent to the
    International Space Station
