At this interactive exhibit, the visitor’s mission is
to design a new vehicle for interplanetary travel. 
First they choose a destination - Mars, Jupiter and
its moons, Alpha Centauri, or our Moon.  Visitors go
on to select the number of crew, type of propulsion system, and supply load.  As decisions are made,
3-D wire frame models of a habitat module, cargo
bay and propulsion system appear in the design
window.  When the spacecraft is complete, the
visitor is presented with a fully rendered 3-D model
of the final design.
