Moon

Factual error: When Sam speaks with his daughter on the long range phone there is virtually no delay between some questions and answers. It takes over two seconds for radio waves just to travel from the Moon to the Earth and back in a straight line. The interval between question and answer physically can't be shorter than that and realistically should be around 3 seconds or even more, accounting for additional signal relays and time needed for a person to form a statement. Same for the communication between Gerty and the Lunar employees when Sam 2 got out of his infirmary bed.

Factual error: The Earth and the Moon are not in the same phase. The Earth is gibbous, while the Moon is crescent. In the real world, they should be in almost exactly the same phase from every angle of view. (00:01:50)

Continuity mistake: When Sam 2 places Sam 1's helmet on his head before placing him back into the damaged rover, the faceplate is still blood-spattered and dirt-smeared, obscuring Sam 1's face. However, when Sam 1 is settled into the seat in the rover, the faceplate is very clean and his face is visible.
