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 VSaturn V Space Shuttle Ares I Ares V

External Tank (ET)
2 Solid Rocket Boosters (SRB)
Orbiter
The whole system is called the Space Shuttle.
STS-133 (Space Transportation System)
Space Shuttle Flight
Which was used for Apollo?
Which did 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.

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.

Thrust Structures
What are some ways NASA engineers could make a
launch vehicle as lightweight as possible?
[Type responses in the chat]
Build the lightest weight thrust structure that will withstand the force of launch to orbit at least three times.
The Challenge:
The Design Challenge
Engineering Design Process
Design and Results Sheets
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)
• Launch to orbit = propelling a 1-liter bottle of water approximately 1 meter into the air
Definition:
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.

Teacher Preparation
Time and Materials• 4-8 hours of prep time• Six 45 minute class periods• Build the launcher and rocket• Materials for classroom activity
Teacher Kit• Kit available from NASA CORE at

Modifications and
Extensions
Customizations
• Allow modifications of cardboard• Allow repairs • Increase the rocket mass• Design with alternative materials• Limit designs by cost (budget)
Keep inspiring your students.
NASA always needs workers interested in Science, Technology, Engineering and
Mathematics.
