A main Project Gemini objective was to demonstrate the feasibility of working outside of the spacecraft.
The Gemini spacecraft hatch was designed to be opened and closed in space to allow an astronaut to leave the vehicle,
known as Extravehicular Activity (EVA).
12 latch assemblies on each hatch allowed the hatch to be locked securely.
Latch assemblies shown at top were modeled using SolidWorks. Dimensioned McDonnell engineering drawings were referenced
to create the models.
Latch model at left is locked; latch model at right is unlocked.
