Title: Space Exploration Past, Present, Future


1
Space Exploration Past, Present, Future
2
Space Exploration The Big Picture
  • Space exploration is still in infancy. Although
    we have learned a lot, we still have a lot of
    questions.
  • The cost of space exploration mandates that we
    work together with other countries.
  • Example International Space Station (ISS)

3
NASA National Aeronautics and Space Administration
  • Accomplishments
  • First to land someone on the moon
  • Invented the space shuttle
  • Developed many products for space that we now use
    as everyday products
  • Example Velcro

4
We Are Curious
  • and so we study space. Things that we need to
    know about space exploration include
  • Rockets
  • Artificial satellites
  • Space probes
  • Space stations
  • Space shuttles
  • Remote sensoring devices
  • Space suits
  • Radar
  • Computers
  • Fuel sources
  • Landing modules
  • Materials that can survive heat and pressure
  • Solar panels
  • Living quarters
  • Biomedical equipment
  • Air purification devices
  • Telescopes
  • And many more

5
Space Exploration History
  • The space age began on October 4, 1957, when the
    Soviet Union launched Sputnik, the first
    artificial satellite to orbit Earth.
  • The Soviets also achieved the first piloted space
    flight on April 12, 1961.
  • The first cosmonaut was Yuri Gagarin. He orbited
    Earth in a ship named Vostok.

Lets Go to the Moon
  • Apollo 8 orbited the moon 10 times and returned
    to Earth safely on December 21, 1968
  • Neil Armstrong and Buzz Aldrin landed Apollo 11
    on the moon on July 20, 1969.
  • Neil Armstrong was the first person to set foot
    on the moon.
  • The laptops in our classroom are more powerful
    than the computers used to run the Apollo
    program!

7
Space Shuttles
  • A space shuttle is a reusable space craft.
  • First used in 1981.
  • Able to land on an ordinary airfield.
  • Two shuttle tragedies in 1987 and 2003.
  • Shuttles replaced the previous method of space
    flight Rockets and capsules.

8
The Space Race and Cold War
  • Our ability to achieve our space goals became an
    indicator of our status as a great nation, and
    the Soviets were our top competitors.
  • This occurred during a time in our history known
    as the Cold War.
  • This was a time when our relationship with the
    Soviets was, well, cold.
  • The intense rivalry between our two countries led
    us to some amazing accomplishments.

Probes Vs. Human Pilots
  • Probes can make space flight cheaper, safer, and
    faster.
  • Human pilots can make decisions when things dont
    go as planned.

We need both. We need balance.
10
Hubble Space Telescope
  • The Hubble Space Telescope's launch in 1990 sped
    humanity to one of its greatest advances in that
    journey. Hubble is a telescope that orbits Earth.
    Its position above the atmosphere, which distorts
    and blocks the light that reaches our planet,
    gives it a view of the universe that typically
    far surpasses that of ground-based telescopes.
  • Hubble is one of NASA's most successful and
    long-lasting science missions. It has beamed
    hundreds of thousands of images back to Earth,
    shedding light on many of the great mysteries of
    astronomy. Its gaze has helped determine the age
    of the universe, the identity of quasars, and the
    existence of dark energy.

MRI
  • Stands for Magnetic Resonance Image
  • In the mid-1960s, as a prelude to NASA's Apollo
    Lunar Landing Program, the Jet Propulsion
    Laboratory developed the technology known as
    digital image processing to allow computer
    enhancement of Moon pictures. Digital image
    processing has found a broad array of other
    applications, particularly in the field of
    medicine, where it is employed to create and
    enhance images of the organs in the human body
    for diagnostic purposes. Two of these advanced
    body imaging techniques are CT or CATScan and
    Magnetic Resonance Imaging (MRI).

13
The Future
  • Exploration at greater distances
  • Extended stays
  • Humans need to be ready and educated for the
    space travel of the future

14
Some Difficulties Include
  • Radiation exposure
  • Lunar dust
  • Food and Nutrition
  • Exercise
  • Differing levels of pressure, atmosphere
    composition, and gravity
  • Sleep loss
  • Risk of bone fracture
  • Reduced muscle mass
  • Reduced aerobic capacity
  • Mental disorders arising from extreme, confined,
    and isolated conditions
