3 Challenge #4 Launch CEV into orbit so that it may rendezvous with the International Space Station. The goal is to launch the CEV 3 meters. Be able to be used over and over again. Demonstrate a repeatable outcome. If you set up the Launcher the same way twice, the CEV should travel the same distance both times. Repeatability is more important than distance.

4 Engineering Design Process – (Ask) DO What Design Must DO: Launch the CEV. CEV & Launch vehicle must travel 3 m. Be reusable (can’t fall apart). Repeatable Results. Ask Imagine Plan Create Experiment Improve Entry

5 CEV Launch. Launch the CEV. Accuracy (hit the target on the floor). Control & Adapt Launch to Improve Results. Be reusable. {Doesn’t Break} Be Repeatable Three launches should have similar/identical results. Changes in force or direction should be predictable and controlable.
