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 NASA’s use of lightweight, strong materials for launch vehicles Focus on thrust structures Focus on thrust structures NASA’s history of testing rockets NASA’s history of testing rockets

Which vehicle is the shortest? a)Saturn V b)Space Shuttle c)Ares I d)Ares V

Space Shuttle

Which vehicle has the least weight at takeoff? a)Saturn V b)Space Shuttle c)Ares I d)Ares V

Launch Vehicles

The Challenge: Build the lightest weight thrust structure that will withstand the force of launch to orbit at least three times 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 Launch to orbit = propelling a 1-liter bottle of water approximately 1-meter into the air

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)

Thrust Structures

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