9. NASA Connection

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

11. 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

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

13. B. Space Shuttle

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

15. Launch Vehicles

16. Human Factors This full scale model of a portion of the Ares I was built at Marshall Space Flight Center to see how the pieces would fit together. When the rocket needs servicing, will a human be able to get to the appropriate place safely and without damaging the parts of the rocket. This is the one of the stages of the rocket.

17. Launch Vehicles

18. External Tank (ET) 2 Solid Rocket Boosters (SRB) Orbiter The whole system is called the Space Shuttle. STS-133 (Space Transportation System)

20. Rocket Staging Which was used for Apollo? Which does the Space Shuttle use?

21. 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

22. 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

23. Comparing rockets

26. 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)

27. Thrust Structures

30. What are some ways NASA engineers could make a launch vehicle as lightweight as possible? [Type responses in the chat]

31. Design Constraints Use only the specified materials Use only the specified materials Must be taller than 5 centimeters Must be taller than 5 centimeters Must allow space in the center for fuel lines and valves (represented by 35mm- film canister without lid) Must allow space in the center for fuel lines and valves (represented by 35mm- film canister without lid)
