2. Overview : The History of Space Exploration

3. The History of Traveling Back to the Moon

4. The 1 st Manned Mission on the Moon

5. Now its time to go back to the Moon…

6. Can we live on the Moon?

7. Aeres I and Aeres V Langley Research Center

8. Terms to Know What are ratios/proportions? the relationship/comparison in quantity, amount, or size between two or more things Example If you have a classroom with 4 girls and 2 boys: The ratio of girls to boys is: 4/2. The ratio of boys to girls is 2/4.

12. Scale Factor The number that is multiplied to make objects the same size. 364 x 305 100 305x = 36400 305 305 x = 119.34

13. Terms to Know What is Diameter? The distance across a center point of a circle What is radius? Half of a surface starting at the center point of a circle (1/2 diameter) Formula to find the area of a circle? 2 r Diameter Radius

14. Comparison of Crew and Command Modules 16.404 feet12.795 feet Orion Crew Module (NASA Concept) Apollo Command Module

15. Area of Crew Modules rr = radius Area of Orion Crew Module (8) = 64 = 201 ft Area of Apollo Command Module (7.5) = 56.25 = 177 ft 2 2 22 2 16.404 feet 12.795 feet

18. NASA’s Vision/Goals WE’RE GOING BACK TO THE MOON!! Langley Research Center

19. Will you be the next NASA astronaut, engineer, or scientist?

20. Mars Mars is smaller and colder than Earth It has a thin atmosphere and polar ice caps, and dry riverbeds crisscross its surface. There are no signs of great civilizations past or present on its red surface. In August 1996, though, scientists announced the discovery of possible microscopic fossils in a meteorite from Mars. Trace elements prove that it came from Mars For more info view the Mars DLN show
