Thrust Structures
43
What are some ways NASA engineers could make a launch
vehicle as lightweight as possible?
44
The Challenge:Build the lightest weight thrust structure that will withstand the force of launch to orbit at least three times.

Design Constraints
• Use only the specified materials• Taller than 5 centimeters • Must have space for fuel
50
Launch to orbit = 1 meter

Modifications and
Extensions
55
Modifications
• Allow modifications using cardboard• Allow mid-test repairs • Change the rocket mass• Design with alternative materials• Limit designs by cost (budget)
56
If it costs $10,000 to lift a pound (half a kilogram) of payload into
orbit, calculate the cost of sending yourself into space.
