2 December 17, 1903 First Flight 120 feet in 12 seconds.

3 Look how far weve come! Orbiter length: 122 feet

4 8,000 Miles13,000 Kilometers A straight line passing through the center of a circle or sphere.

5 2,100 Miles or 3,500 Kilometers Our moon is 1/4 th the diameter of the Earth.

6 25,000 Miles40,000 Kilometers The size of something as given by the distance around it.

7 The point in the orbit of a heavenly body at which it is farthest from the earth. 252,000 Miles or 405,000 Kilometers

8 The point in the orbit of a heavenly body at which it is nearest to the earth. 224,000 Miles or 360,000 Kilometers

9 The average value of a set of numbers. 240,000 Miles or 386,000 Kilometers

10 Using two objects to represent the Earth and moon, lets estimate how far away the moon is from the Earth. An approximate judgment or calculation.

11 Using diameter: 240,000 miles/8,000 miles = 30 Earths 385,000 km/13,000 km = 29.6

12 Using circumference: 240,000 miles/25,000 miles = 9 ½ 384,500 km/40,000 km = 9 ½

13 How long would it take to go to the moon? Lets take a car. Well even go faster than the speed limit (since there are no signs in space). Lets say, 100 mph. That means it will take 2,400 hours = 100 days! Thats too long! Lets take a jet instead. A commercial airliner goes about 600 mph. Now well arrive in 400 hours = 16 ½ days!

14 The Saturn V rocket took us to the moon. With this rocket the trip took only 3 days! To date, the Saturn-V is still the largest rocket ever built and flown. It was 363 ft tall.

15 Humans took their first trip to the moon in All we did then is fly around it. In July of 1969 Neil Armstrong and Buzz Aldrin were the first humans to walk on the moon. The last time we went to the moon was in 1972.

16 1972??? Are you joking? The median household income was $9,697. Cost of a first class stamp was 8 cents. The pocket calculator was invented by Texas Instruments. The VW Beetle was the biggest selling car. M*A*S*H and the Waltons premiered on TV.

17 Even the Brady Bunch stayed on the air from 1969 until 1974!

18 How far away from the Earth are the Space Shuttle and the International Space Station?

19 An approximate judgment or calculation. Using two objects to represent the Earth and the shuttle orbiter, lets estimate how far away the orbiter is from the Earth.

20 Orbiting Altitude: Average 220 Nautical Miles or 407 km

21 Approximately how large will the International Space Station be when its completed? 1 Field 2 Fields3 Fields

22 Approximately how large will the International Space Station grow? 2 Fields!

23 Where will we go next? This looks like a lovely sunset…but it isnt from Earth!

24 What about a trip to the Grand Canyon of Mars? Valles Marineris is about 2500 miles long and up to 4 miles deep.

25 Theres a lot to see on Mars…. Like the face or the Smiley crater.

26 But you better plan ahead…there is no McDonalds there yet!

27 You should plan when to leave for this trip. At its closest, Mars is still tens of millions of miles away from Earth. Still, the decreased distance during "closest approach" allows for fuel-conserving flights to Mars every 26 months and a good view of Mars once or twice every 15 to 17 years for Earth-bound sky watchers.

28 Distance from Earth: Minimum 35 million miles (56,000,000 km) Maximum 250 million miles (399,000,000 km).

29 Using two objects to represent the Earth and Mars, lets estimate how far away Mars is from the Earth. An approximate judgment or calculation.

30 How long would it take to go to Mars? Lets take a car. Well even go faster than the speed limit (since there are no signs in space). Lets say, 100 mph. That means it will take 560,000 hours = 23,333 days = 64 years! Thats too long! Lets take a jet instead. A commercial airliner goes about 600 mph. Now well arrive in 58,333 hours = 2,430 days = over 6 years!

31 Perhaps the new Crew Exploration Vehicle currently being developed will take us to Mars. With current technology, it will take an average of 7 months to travel one way to Mars.

32 So WHY are we spending all this $$$ in space?

33 The same year, Americans spent more on junk food! Way more!

34 How much return do we get on our dollars from this?

35 Joysticks Protective Helmets Windsurfer Fin These are just a few of the ways we benefit from the space program:

36 Insulin Delivery System Air Traffic Control Equipment Physical Therapy Machines

37 Spinoff Applications… the list goes on and on! Medical Imaging Programmable Pace Maker Lightning Warning System Cordless Hand Tools Ear Thermometer Smoke Detector Fire Fighter Equipment Invisible Braces Satellite Dish Composite Materials Advanced Plastics Laser Angioplasty Scratch Resistant Lenses Water Purification Systems Air Quality Monitor
