Capsule MSC-307 was most likely built to test and evaluate the size and shape of the Gemini capsule design. There is no indication that it was ever outfitted for actual astronauts, but it would have been used for splashdown recovery training in preparation for the manned Gemini missions.
In spacecraft design, a boilerplate is a non-functional item that meets spacecraft “form and fit” requirements only and tests the developing design against a small number of specific design requirements. Boilerplate models are an economic way to test spacecraft designs as they evolve into their final, fully functional shapes. Boilerplate tests are used to validate flight loads, aerodynamic performance, and interfaces with other parts of the launch system, as well as to develop procedures for emergency entry and exit, maintenance support, ground handling, and transportation. The boilerplates were used during the development of the Mercury, Gemini, and Apollo manned space vehicles.

This “boilerplate” was used for testing and training in NASA’s Gemini program. Hornet volunteers are rebuilding it to closely resemble the interior of the actual Gemini spacecraft. In 2026, we hope to be able to have guests sit inside and interact with the instrument panel. They will get experience this tiny two-person spaceship just like real astronauts training to fly to the moon. See photos below for rendering of the interactive.
