Roz (Peri Gilpin) is in the process of producing a documentary about the NASA space program and wants Frasier (Kelsey Grammer) to narrate the project. Alas, before long Frasier has all but taken over production of the documentary himself, leading to a big-time feud between hero and heroine. By the time the crisis reaches its peak, even former astronaut and U.S. senator John Glenn (as himself) has gotten involved -- and in this case, the mission is not "Go"! Jane Leeves was on maternity leave during filming of this episode, and does not appear. ~ Hal Erickson, Rovi
