In 1966, astronaut Buzz Aldrin took an orbital mission on Gemini 12 and performed the world’s first successful spacewalk. The mission of the Gemini program was to show that astronauts can effectively work outside of spacecraft - which paved the way to the first moon landing in 1969. The flight lasted a total of 5 hours and 30 minutes. The spacecraft is now on display at the Adler Planetarium in Chicago.
