Good questions Magnum
The mission would be a 'near future' mission, so the ship shouldn't look too advanced. It would need to have an advanced drive system (FTL), consider it a 'breakthrough' and first application. I'm still considering what means I'll use, whether fusion power using something like the Tokomak (sp?) design or just something other (high energy sweat molecules squeezed from middle school gym clothes heh).
The means of propulsion is not the vital part. If the ship has some visible means of propulsion (NOT warp nacelles, too advanced for my kludge
) it would be enough. I would like it recognizably 'primitive' though, not the sleek starbuggies y'all are normally usin' round here
The mission would be scientific, not to build a colony. It would not be one way, but would be long duration (9 months to 1 year). Some form of lander would be needed. I'd intended to use NASA's CEV to get the command crew to lunar orbit, where the ship would launch from (NASA has a nice animation of the CEV liftoff, which I'd make use of).
The basis of the project is the visit of our mission to a distant, earth-like world. I would use the mission to tie in to a wide range of topics covered under our 7th and 8th grade curriculums; Energy and Motion, Space Science, Astronomy, Geology/Earth Science, Meteorology and Climatology, Biology, even Paleontology and, perhaps, Archeology and Communications (I haven't decided if there will be intelligent life, I'm leading towards 'no'). The class would go through topic lessons, then apply what they learned by aiding the ship's crew, setting up experiments, analyzing data gathered by the crew, suggesting courses of action, problem solving, etc etc.
Hope that answers your questions. Thanks for the interest!!
