Not entirely sure yet, but not a bad assumption. Final weight to be determined. This part is surprisingly light so far. I'm shooting for an I161 White Lightning, with an I245 Mojave Green as a backup if the weight creeps up (likely). This should keep the altitude reasonable since it will likely have a really big chute.

P.S. The enclosed compartment under the launch rod is where my spares (igniters, tape, super glue, etc.) will be. In the actual operation, this will by default be left behind on the surface of Bong and available to others should they be "stranded". Remember, pre-positioned supplies will likely be part of any Mars missions.
