This is an engineering design challenge activity. Learners will use balloons to investigate how a multi-stage rocket, like that used to launch the Interstellar Boundary Explorer, or IBEX, spacecraft, can propel a satellite to a specific orbit. Learners will construct a two-stage balloon rocket that will be required to reach a particular location on the balloon track, simulating the proper orbit around Earth to be reached by the IBEX satellite. This activity complements other IBEX informal education materials. An instructional video explaining how to facilitate this activity is available: http://bit.ly/ZwlFf4.
