Comment:

The internal detail of the spacecraft geometry reflects a host of quick estimates about component sizes and structural layout.

Engineers' physical presence allows them to use hand gestures to communicate around electronic 3D drawings.

Paper drawings support additional discussion before the CAD engineer puts geometry into electronic form.

An array of cabinets (top right) stores published records of previous JPL missions: experienced engineers use these to recall design points from past work (bottom left).

The small whiteboard in the main room preserves snapshots of many design decisions worked out during the course of a study: the figures appear meaningless outside the context of the moment.

Toward the end of the study, the spacecraft geometry takes on its final form, and the deputy systems engineer reviews the collected parameters of the design.
