Personal Satellite Assistant Earth to Orbit Engineering Design Challenge
Students take on a challenge similar to the one NASA engineers had to solve: they will use the forces produced by small fans to control the rotation of a horizontal, near frictionless wheel. The response of the wheel to these tiny forces is similar to objects in the microgravity environment of space. Students are given a set of pre-determined missions to accomplish with the wheel.
