"Deep Space Homer" is the fifteenth episode of The Simpsons' fifth season and first aired on February 24, 1994. The episode was directed by Carlos Baeza and was the only episode of The Simpsons written by David Mirkin, who was also the executive producer at the time. The episode follows Homer becoming an astronaut, and the ensuing chaos when the navigation system on his Space Shuttle is destroyed. Buzz Aldrin and James Taylor both guest starred as themselves. The critically acclaimed episode became the source of the Overlord meme, and features numerous film parodies, mostly referencing The Right Stuff and 2001: A Space Odyssey. A copy of the episode is available for astronauts to watch at the International Space Station.
