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

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.

The Lesson in Detail

Thrust Structures

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.
