An extremely rare complete American spacesuit from the Gemini space program is expected to sell for up to $150,000 at auction this week.

The main body of the suit was worn by Air Force chief warrant officer Mitchell Kanowski during high-altitude tests of the Gemini emergency launch escape system.

Kanowski jumped from a NASA training aircraft at high altitude to test the suit in the event of a takeoff failure during launch.

“What makes it significant is that it’s the only known complete American spacesuit to come to market,” Sotheby’s Vice-president and Senior Specialist for Books and Manuscripts Cassandra Hatton told Fox News.

“To see something like this is very, very rare indeed.”

The Gemini program, which ran from 1961 to 1966, was an important stepping stone for the subsequent Apollo missions.
