Other mistake: Every time someone calls, either on the comlinks, or the wall panels, there always appears to be a blank wall immediately behind the person on screen, even when the camera cuts to the person calling.
Revealing mistake: Every time "red alert" is on the screen, it's easy to see the screen is an overlay with "red alert" cut into it.
Revealing mistake: Most of the time, as the Eagles are taking off, landing, or flying, the wires used to accomplish these actions are visible.
Revealing mistake: Many times throughout the series, the wires that hold up and control the models of the Eagles are easily seen.
Character mistake: When Koenig and Bergman finally reach his office, Martin forgets his lines briefly.
Other mistake: At Waste Area 2, as Nordstrum throws Steiner, his visor flips open.
Continuity mistake: The first time the two crew men in the moon buggy are seen, the numbers on their suits are eight and three. The next moon buggy scene, the two in the suits are numbered eight and three again at first, but when they're testing the domes, the numbers change to nine and zero.
Other mistake: As Zoref pulls the reactor door open, the wig wrinkles up on the back of his neck. Also, when the door is half way open, he's still holding it, then he's suddenly several feet away from it when it's still swinging open.
Visible crew/equipment: After the creature that was Zoref pulls the reactor door open, the camera crew is reflected on the door's surface.
Other mistake: As they track Zoref, Victor calls for a view of Corridor 16, then after viewing it, calls for Corridor 49. In both views, it is the same Corridor, as evidenced by the number 16 on the lighted wall panel on the corner facing the camera.
Continuity mistake: As Zoreth looks around after his wife closes the door, he closes a book he's holding. A second later, he's holding it by one cover, the book hanging open.
Revealing mistake: As the camera looks at the exhaust port of the probe's engine, there's water dripping off the bottom, showing the stream is water vapor.
Revealing mistake: As the Voyager probe lands, the control wire lowering it is visible.
Alpha Child - S1-E7
Revealing mistake: As the alien ship approaches Alpha on screen, there is a round, blank area where the model moves, and as the vessel nears the camera, the edge of the cell used for the picture of the vessel is visible.
Alpha Child - S1-E7
Revealing mistake: As Jackie is drawing, Koenig's face comes up on the communicator. As the screen goes from the idle/test pattern screen to the identity screen, you can see the picture jump, suggesting there was a pause in filming to allow the unit with the idle screen and the picture screen to be swapped out.
Continuity mistake: The panel Tony hits with a tomahawk in his quarters first appears to be molded plastic, then in a close up, appears to be painted wood, as the wood grain where the panel above is smooth.
Continuity mistake: In the earlier part of the story, Tony was the only survivor and took the pointed module to escape. As Koenig and company return to the probe and dock, the module is back in place.
Revealing mistake: As the Eagles take off from Piri, the wires used on the models to "fly" are easily seen.
Continuity mistake: As the alien struggles with the security personnel, it's easy to tell the alien actor and the stunt double. The hair color and style change between distance and close up shots.
Revealing mistake: As Koenig tells of the attack, his feet are passing by the "dead" Mike Baxter. As they pass, Baxter's eyes flicker for a second.
Answer: Not necessarily - The gravitational fields of Earth and the Sun could have deflected the moon away from the solar system.
