  1. SPACE EXPLORATION Reaching beyond the sky

  2. The Beginnings of an Idea • Early Space exploration ideas were influenced by Sci-Fi • Jules Verne & H.G. Wells • First realisitic Proposal was made in Russia – 1903 • Konstantin Tsiolkovsky. • Engineering a rocket was shown to be viable in 1919 • Robert Goddard – Father of Rocketry

  3. Milestones in Space Exploration • 1944 – Germans launch first rocket into space • The V-2 rocket • http://www.youtube.com/watch?v=8gnkUQWpNHY • 1957 – Soviet Union launches Sputnik • The first artificial satellite • http://www.youtube.com/watch?v=qvPzUAeWZZY • 1961 – Soviet Union launches first man into space • Yuri Gagarin – orbited the earth a single time • 1969 – United States Lands First man on the Moon • Neil Armstrong

  4. Where are we going? • Manned missions • Apollo missions (Discontinued), The Moon • Shuttle Missions (Discontinued), LEO – Low Earth Orbit • Space Stations (ISS – Ongoing), LEO – Low Earth Orbit

  5. Unmanned Missions • Probes sent out to many planets, satellites, asteroids, comets… • Voyager – Outer Planets, first Interstellar probe • New Horizons– Pluto & beyond • Messenger – Mercury • Dawn – Asteroids • Landers (Probes landed on the surface of celestial bodies) • Huygens – Titan • Venera – Venus • Viking – Mars • Rovers (mobile landers) • Pathfinder – Mars • Spirit & Opportunity – Mars • Curiosity – Mars

  6. Voyager

  7. Mars Exploration Rover

  8. Where can we get to? • Travel times to various Solar system destinations (Approximate!) • Low Earth Orbit (Shuttle, ISS): ~10 minutes • Moon: 2 days • Venus: 4 months • Mars; 6 months • Jupiter: 1 to 6 years • Saturn: 3 to 7 years • Uranus: 5 - 8 years • Neptune: 6 – 10 years • Pluto: 9 Years or more • Kuiper Belt? Oort Cloud? Alpha Centauri? Andromeda?

  9. How far have we gone? • Pretty far…

  10. How far have we gone? • But still haven’t left our own solar system…

  11. Alien Communications? • Alien Communication

  12. Space Exploration Questions Your thoughts.

  13. Writing and discussion • Today we will be thinking about and having a class discussion on 3 major question regarding space exploration. • You will discuss the questions in groups of 4, then write individual paragraphs about the questions. • After each paragraph you will be asked to share your thoughts in class discussions.

  14. What’s the point? • Many people ask: “Why do we bother going to space at all?” • What is your opinion? • Should we be spending the money? • Using the scientific and engineering resources? • Should we be risking the lives? • Detail your position on the matter, and explain why you feel that way. Address the specific concerns listed above.

  15. Not because it is easy… • Regardless of how you feel about it personally, spaceflight and exploration is happening and will continue to happen. • We do this in the face of the many difficulties that are an inescapable part of space travel. • What specific difficulties can you think of for travelling into space? For sending humans into space? What are the dangers?

  16. But because it is hard! • Whether you realize it or not, space exploration has produced many benefits, creature comforts, and new technologies for us on Earth. • What do you think some of those things could be? • Make a list of advances that you think could have come from space research but benefit us here on Earth. Be detailed in describing the advances, why you think they came from space research, and how they can benefit us on earth.
