S1, E3: To test man's ability to survive on the moon, Captain Anthony (Tony) Nelson, and his fellow astronaut, Captain Roger Healey, are ordered to spend a week, in Furnace Canyon, Nevada, 100 degrees in the daytime, 10 below freezing at night. Except for water, they are to live off the land. Jeannie hides in Tony's canteen. Tony tries to make Jeannie understand that she is destroying the value of the mission, but she sticks with him. While Roger barely survives, Tony has every luxury, from food and a harem tent, to a final ride on a camel to finish the journey. Dr. Bellows is baffled to find that while Roger has lost twelve pounds, Tony has gained five. When Tony tries to explain Jeannie's presence, Dr. Bellows concludes that he has the imagination men need to survive on the moon and recommends Tony for a more arduous test, Operation Extinction. Tony tells Jeannie he is taking her with him, but imprisons her within her bottle, determined to go on the mission alone.
