Thirty-nine years after its only trip to space, the Gemini XII will be restored over the next three months at the Kansas Cosmosphere and Space Center.
The spacecraft that carried astronauts Jim Lovell and Edwin "Buzz" Aldrin on a November 1966 mission arrived in Hutchinson this week.
Restoration officials said that despite some deterioration and corrosion, the Gemini was in good shape.
"This is pretty much the condition it was when it became the Smithsonian's property in the late 1970s," said Jim Remar, vice president of museum operations for the Cosmosphere.
Remar said the first step would be removing the cover and taking an inventory of the spacecraft's parts and condition. The Cosmosphere previously restored the Gemini VI and Gemini X.
The Smithsonian Institution owns the spacecraft, which will go on display at the Adler Planetarium in Chicago after being restored.
