NASA Connection
Why is it important to make the launch vehicle as
lightweight as possible?
[Type responses in the chat]
Background• NASA’s use of lightweight, strong
materials for launch vehicles• Focus on thrust structures• NASA’s history of testing rockets
Which vehicle is the shortest?a) Saturn Vb) Space Shuttlec) Ares Id) Ares V
B. Space ShuttleB. Space Shuttle
Which vehicle has the least weight at takeoff?
a) Saturn Vb) Space Shuttlec) Ares Id) Ares V
Launch Vehicles
Launch Vehicles
The Challenge:
• Build the lightest weight thrust structure that will withstand the force of launch to orbit at least three times
Definition:
• Launch to orbit = propelling a 1-liter bottle of water approximately 1-meter into the air
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)

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