2. 12.3 SPACE TRAVEL By : Ricky and Eaman

3. SPACE TRAVEL First stage, sending robotic spacecraft When that was a success humans were sent Moon was the first target First man to go to the moon was Neil Armstrong One of the greatest success was the Canadarm reward for space travel was the spinoff technology that we use for our daily lives like Frozen-dried food, high tech running shoes, bicycle helmets, cold weather clothing and light sportswear

4. RISKS OF SPACE TRAVEL Biggest risk Equipment Failure Another risk bone and muscle loss Asteroids are another risk for astronauts and there spacecraft Over a million pieces of “Space junk” Space shuttle holds up to 750 000kg of explosive fuel the most devastating crash in the history of NASA happened on February,1,2003 it was the Columbia crash Did you know.. In space an apple sized metal ball would crash with the explosive force of 2 dozen sticks of dynamite.

5. Medical Risks There are also many medical risks by going to space Bone and Muscle loss Hearing Loss Puffy – head bird – legs syndrome Physiological effect

6. NASA NASA - National Aeronautics and Space Administration Works for the United states government Responsible for space program, aeronautics and aerospace Exploring bodies of the solar system Such as “ New horizons” the space shuttles flying motion is describing Newton's 3 law for every action there is and equal or and opposite reaction

7. NEW IDEAS NASA’s top 2 concept space transporter are Space elevator, Space sled Space elevator worth 5-8 billion dollars space elevator’s cable connects from the north pole to the atmosphere cables length 36 000 km long altitude cost $200 per 5 hour ride would connect with a laser beam from earth

8. NEW IDEAS (CONT.) Space sled estimated to be $100 per launch Would use a slingshot reach maximum speed of 1000 km/h would use a 300+ ton rock reduce fuel to Orbit by 40% NASA’s idea of the space sled

9. THE CHALLENGER The challenger STS-51-L Had happened because of an O-ring in the right solid booster rocket O-ring failure caused breach in solid rocket booster Allowed hot pressurized gas to the rockets motor On January 28th 1983 was when the crash happened http://www.youtube.com/watch?v=Ud7iPANigWY

11. QUESTIONS 1) What is Newton’s 3 law? 2) What is space junk? Name 3 3) Name the 5 spinoffs of space exploration technology that we use on Earth? 4) what was the name of the crash that happened on February,1,2003 5) Should large amounts of money be spent on space explorations rather than being used for projects on Earth?

12. Answers may vary 1) For every action there is an equal and opposite reaction 2) Flakes of paint, small bolts, and old satellites 3) Frozen-dried foods, high tech running shoes, bicycle helmets, cold weather clothing, light sports wear, sunglasses, insulin pumps, eye examination systems, locater beacons, and self repairing computers 4) A modern word that combines 2 concepts. The first part comes from Latin Terra which means Earth. Forming is added to indicate change. 5) Your opinion
