A McDonnell concept for using Gemini for extended duration missions. The basic Gemini would dock with an Agena upper stage. Between the docking collar and the Agena is an orbital shelter where the crew would live and work for weeks at a time. The crew would transfer from the Gemini to the miniature space station via an inflatable airlock.
