• 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.
• Background photo shows Gemini IV right hatch at the Smithsonian National Air & Space Museum.
