Our journeys to the stars will be made on
spaceships created by determined,
hardworking scientists and engineers applying
the principles of science, not aboard flying
saucers piloted by little gray aliens from some
other dimension.
— Robert A. Baker
in “The Aliens Among Us: Hypnotic Regression
Revisited”, The Skeptical Inquirer, 1988
Why Explore Space?
• Colonization - Marvin the Martian wants to
colonize Earth and We want to colonize Mars
• Science - We want to understand the
universe and other planets
• Communications - Every day we use hundreds
of satellites to communicate with other
Earthlings
• Weather and Navigation, and the list goes on
What’s In Space?

History of Space Exploration
The heavens declare the glory of God,
And the firmament showeth His handiwork...
In them He has set a tent for the sun….
 from Psalm 19
• For thousands of years, humans observed the night
sky
• They noticed the patterns and named groups of
stars constellations
• They noticed that some of the stars wandered
around among the others
• The ancient Greeks called these Wanderers Planets
• Aristarchus (c. 300 BC) first suggested that the
Earth revolved around the Sun
Pre-Modern History
• Tycho Brahe (left)
(1546-1601)
made the observations
that led to
• Johannes Kepler
(1571-1630) discovering
how the planets go
around the sun, followed
by
• Isaac Newton
(1643-1727)
inventing the
mathematics used to
prove Kepler’s
discoveries
Some Modern History
• In 1814 Sir William Congreve’s
(1772-1828) rockets were used by
British at Ft McHenry, witnessed
by Francis Scott Key
• In 1903 the Wright Brothers made
the first powered airplane flight
• In 1926 Robert Goddard (left)
(1882-1945) flew the first liquid
fuel rocket
• In 1957 the Soviet Union launched
Sputnik the first artificial satellite
• In 1981 the Space Shuttle Columbia
made the first shuttle flight
"The earth is the cradle of mankind - one cannot remain in
the cradle forever" - Konstantin Tsiolkovsky (1857-1935)
