The Man Trap - S1-E2
Continuity mistake: When the creature makes it's way through the ship and finds McCoy's room, it stops near the wall with a red vent behind it. It changes back to Nancy in a dissolve cut, but suddenly it's much closer to the walk and is now closer to the vent, something that would not have happened by a simple morph like seen before. (00:28:45)
The Man Trap - S1-E2
Continuity mistake: When Kirk is telling Crater that he needs him and his wife to stay on their ship till he finds out what killed his man, Kirk has his arms crossed.

Continuity mistake: Kirk jokes with Bones after they land about flowers and is holding some hay or grass in his hands.

The Return of the Archons - S1-E22
Continuity mistake: After Kirk and the landing party beam down, they are met by a man who tells them where they can stay for the night but they will have to hurry because it's almost the "red hour." At that time the camera shows a clock that reads 5:58. After being introduced to the daughter of the man who can give them shelter, a gong rings and magically it is 6:00, 2 minutes later, although only 32 seconds of real time has passed. (00:05:18 - 00:05:50)
Operation -- Annihilate! - S1-E30
Continuity mistake: After Kirk orders Uhura to reestablish contact with Aurelan's transmitter, when Uhura replies that they do not acknowledge her contact signal, Uhura's communications earpiece is not in her ear, but in the next shot it's suddenly back in her ear. (00:06:10)
Continuity mistake: When Kirk informs Galileo that all systems are clear for takeoff, in the shot from inside the shuttlebay as Galileo turns to launch, the shuttlecraft Columbus is also in the hangar deck, but when Galileo exits Enterprise the Columbus is gone in the exterior shot. (00:01:45)

As Kirk (the stunt double) goes for the knock out blow, the shirt is only a little torn in the front. Then the close up on Kirk catching Finney, his shoulder is exposed again.
Continuity mistake: While Kirk questions Spock about his command decision on the Galileo, shots of Uhura and Mears show the ladies close together at Uhura's station with Mears' hands hidden but close up shots of McCoy show Mears and Uhura in the background further apart from each other and Mears' hands in front of her body.
Continuity mistake: As Scotty starts prying the panel open, it's with a tool in his right hand, and the thumb of his left. After the cut, he's suddenly holding it in his right hand.

Chosen answer: If they're in orbit, they're being pulled along by the planet's gravity well, therefore, impulse engines would only be used for minor corrections and would be "on standby" while in orbit, but not active. (Like keeping your car idling without revving the engine and creating plumes of exhaust).
