Ron Gross’s Jupiter 2 Profiles

Issue 41 of Sci Fi and Fantasy Modeling International features a fine article by Ron Gross about the Jupiter 2. Ron provided some diagrams for publication, but these were not used in the issue. Ron is sharing them with us!

The final Fox profile used for miniature construction, a precise tracing of the articulated Jupiter 2 miniature from a specially processed edge-on print, and a composite diagram displaying the differences. The dotted line denotes the original lower profile “Gemini 12” design from the TV pilot. Note how the additional upper hull stock seems to offset this final lower level extension.

The evolution of the Jupiter 2 hull contour. Top to bottom: The original Fox blueprint, the “Gemini 12” single-level concept from the unaired pilot, the revised “Jupiter 2” design (upon which several models were based), and the distinctive four-foot articulated miniature with working landing gear.

Reconciliation for scale with respect to the revised hull contour. The top diagram depicts the original studio set with selected internal appointments. The dotted line on the right indicates a final exterior revision which allowed for the construction of the airlock and porthole, and also resulted in a deep recess for the primary viewport. Note that in the original pilot version, the astrogator dome could be elevated to the position of the top “blister.” In the final version, the finished roof top gave way to an elevated sound stage, and filming was done below a designated crop line. The bottom diagram illustrates the necessary scale adjustment for the miniature to insure a comfortable fit for the same hardware components.

All primary hardware in unified scale: Even with logical rescaling using a hatchway as a common reference point, it is still physically impossible for certain support hardware to be properly contained.
