- Dr. Zachary Smith: [Talking on small communicator radio] Aeolis 14 Umbra. Come in please. Do you read me? Mission accomplished. Mission accomplished. What do I do now? What clever instructions do you have for me now? How much more money are you going to pay me for this excursion?
- Dr. Zachary Smith: [Sees meteor zooming past observation window] Aeolis 14 Umbra, do you know where I am? Do you know? DO YOU KNOW?
- [Dr. Smith throws radio to floor, then flips Robot power switch on console only to half way position, then leaves]
- The Robot: Incompleted circuit. Incompleted circuit! Damage may result!
- [Flips switch back to on position]
- The Robot: Damage averted. All systems operative.
- Will Robinson: [to Dr. Smith] Well, Maj. West said that when he went to cadet school an excuse like yours wouldn't have gotten him out of Sunday chapel.
- Voice of Lunar Tracking Controller: Hello Alpha Control. This is Lunar Tracking Station Copernicus. Jupiter 2 moving at incredible speed! Far off course, beyond range of our tracking instruments!
- Alpha Control Technician: White House, this is Alpha Control. Message for president on scrambler. Mr. President, status control on Jupiter 2. As of this moment, the spacecraft has passed the limits of our galaxy. It's presumed to be hopelessly lost in space.
- Maureen Robinson: Dr. Smith, is it possible that certain parts of the body don't reanimate as quickly as others? The heart, for instance?
- Dr. Zachary Smith: Mrs. Robinson, I'm afraid the decision no longer rests in your hands or the computer's.
- Prof. John Robinson: What do you mean?
- Dr. Zachary Smith: Your son...
- Maureen Robinson: What about him?
- Dr. Zachary Smith: Oh, there's no cause for alarm. Not yet at any rate.
- Will Robinson: [Downstairs, addressing Robot] Stop it! Stop it! I order you to stop!
- The Robot: [pauses] Negative.
- [Robot smashes arm against console, causing damage and wild gyration of ship, then takes elevator upstairs]
- The Robot: Destroy!
- [Begins slowly lumbering forward]
- The Robot: Destroy!
- Dr. Zachary Smith: No, no! Abort! Can you hear me? Abort! Abort! Abort!
- [Robot blasts Dr. Smith with bolts of electricity, hurling him to the floor]
- Narrator: This is the beginning. This is the day. You are watching the unfolding of one of history's great adventures - Man's colonization of space beyond the stars.
- Narrator: Reaching out into other worlds from our desperately overcrowded planet, a series of deep-thrust telescopic probes have conclusively established a planet orbiting the star Alpha Centauri as the only one within range of our technology able to furnish ideal conditions for human existence.
- Maureen Robinson: I should say something light and clever, shouldn't I? I just can't.
- Alpha Control Technician: This is Alpha Control. The Robinson family will now board the spacecraft.
- Dr. Zachary Smith: The power pack! Pull out the power pack!
- Maureen Robinson: John, look out! Penny, hang on!
- Maj. Don West: [Trying to stop Robot from burning through cabin pressure control on wall] He's breaking through!
- Dr. Zachary Smith: Pull out the power pack!
- Narrator: The Robinson family was selected from more than two million volunteers for its unique balance of scientific achievement, emotional stability and pioneer resourcefulness. They will spend the five and a half years of their voyage frozen into a state of suspended animation, which will terminate automatically as the spacecraft enters the atmosphere of a new planet.
- [Dr. Smith checks his reprogramming of the robot]
- The Robot: At exactly launch plus eight hours: inertial guidance system - destroy; radio transmitter - destroy; cabin pressure control system - destroy.
- Will Robinson: My dad said you were left aboard when you came down to adjust the helium/nitrogen intake.
- Dr. Zachary Smith: That's right.
- Will Robinson: But the helium/nitrogen intake valve's on the UPPER level.
- Dr. Zachary Smith: Oh? Well... Who said anything about the intake valve? It was the emergency supply I was concerned about.
- Prof. John Robinson: [gazing at the star field out the ship's window] It's incredible! Not one constellation you can recognize!
