Gemini 10 spacecraft on display at the Kansas Cosmosphere And Space Center in Hutchinson, Kansas. The Cosmosphere is a must visit destination for any fan of space flight. Gemini 10 featured docking with an Agena rocket, rendezvous with a target still in orbit from Gemini 8, and two EVAs (space walks). Each of the spacewalks had troubles, something which NASA had to work out before attempting a moon flight.
