8. NASA Connection

9. Why is it important to make the launch vehicle as lightweight as possible? [Type responses in the chat]

10. Background NASA’s use of lightweight, strong materials for launch vehicles NASA’s use of lightweight, strong materials for launch vehicles Focus on thrust structures Focus on thrust structures NASA’s history of testing rockets NASA’s history of testing rockets

11. Which vehicle is the shortest? a)Saturn V b)Space Shuttle c)Ares I d)Ares V

12. Space Shuttle

13. Which vehicle has the least weight at takeoff? a)Saturn V b)Space Shuttle c)Ares I d)Ares V

14. Launch Vehicles

17. The Challenge: Build the lightest weight thrust structure that will withstand the force of launch to orbit at least three times Build the lightest weight thrust structure that will withstand the force of launch to orbit at least three times

18. Definition: Launch to orbit = propelling a 1-liter bottle of water approximately 1-meter into the air Launch to orbit = propelling a 1-liter bottle of water approximately 1-meter into the air

19. Comparing rockets

22. If it costs $10,000 to lift a pound (half a kilogram) of payload into orbit, calculate the cost of sending yourself into space. (Sharing is optional)

23. Thrust Structures
