9. Let’s Pause for Questions Please type your questions in the chat!

10. NASA Connection

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

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

13. Saturn V Space Shuttle Ares I Ares V

14. Saturn V First Stage

15. Saturn V Second Stage

16. Saturn V Third Stage

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

18. Space Shuttle Flight

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

21. Space Launch System NASA is moving forward with the development of the SLS, an advanced heavy-lift vehicle that will provide a new national capability for human exploration beyond Earth’s orbit.

22. Splash Test Parachute Test Orion Heat Shield prototype Orion Multi-Purpose Crew Vehicle

23. Splash Test Parachute Test Orion Heat Shield prototype Orion Testing Pad Abort Motor Test

24. Human Factors This full scale model of a portion of a rocket design that was built at Marshall Space Flight Center to see how the pieces would fit together. When this 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 one of the stages of the rocket.

26. The Lesson in Detail

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

32. The Design Challenge

33. Engineering Design Process

34. Design and Results Sheets

35. Design Constraints Use only the specified materials Must be taller than 5 centimeters (2 inches) Must allow space in the center for fuel lines and valves (represented by 35mm-film canister without lid)

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

37. Classroom Sessions Session 1: Introducing the Challenge and Getting Started Session 2: Design 1 Sessions 3 and 4: Designs 2, 3, 4, 5 Session 5: Storyboard/Poster Session 6: Student Presentations

38. Comparing Rockets

41. 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)

42. Let’s Pause for Questions Please type your questions in the chat!

43. Teacher Preparation

44. Time and Materials 4-8 hours of prep time Six 45 minute class periods Build the launcher and rocket Materials for classroom activity

45. Teacher Kit Kit available from NASA CORE at http://core.nasa.gov

46. Let’s Pause for Questions Please type your questions in the chat!

47. ModificationsandExtensions

48. Customizations Allow modifications of cardboard Allow repairs Increase the rocket mass Design with alternative materials Limit designs by cost (budget)

49. Keep inspiring your students. NASA always needs workers interested in Science, Technology, Engineering and Mathematics.
