NASA Connection
Why is it important to make the launch vehicle as lightweight as possible? [Type responses in the chat]
Background NASA uses lightweight, strong materials for launch vehicles Focus on thrust structures NASA s history of testing rockets
Saturn V Space Shuttle Ares I Ares V
Saturn V First Stage
Saturn V Second Stage
Saturn V Third Stage
The whole system is called the Space Shuttle. External Tank (ET) 2 Solid Rocket Boosters (SRB) Orbiter STS-133 (Space Transportation System)
Space Shuttle Flight
Which was used for Apollo? Which does the Space Shuttle use?
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.
Orion Multi-Purpose Crew Vehicle
Orion Testing Pad Abort Motor Test Parachute Test Splash Test Orion Heat Shield prototype
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 the one of the stages of the rocket.

What are some ways NASA engineers could make a launch vehicle as lightweight as possible? [Type responses in the chat]
The Challenge: Build the lightest weight thrust structure that will withstand the force of launch to orbit at least three times.
The Design Challenge
Engineering Design Process
Design and Results Sheets
Design Constraints Use only the specified materials Must be taller than 5 centimeters Must allow space in the center for fuel lines and valves (represented by 35mm-film canister without lid)
Definition: Launch to orbit = propelling a 1-liter bottle of water approximately 1-meter into the air
Definition: Launch to orbit = propelling a 1-liter bottle of water approximately 1-meter into the air
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
Comparing rockets
Comparing rockets
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)
