Early on, the Knight's outer airlock door is declared to be gone. But when the crewmen climb back onto the deck inside after repairing the antenna array, the outer doors can be clearly seen between them before the inner doors close.
The Knight is not rotating or accelerating, yet there is gravity inside. Loose items are tossed and casually dropped but don't float away. Although the crew have (presumably magnetic) boots when they walk around, they also fall down and lie down without the boots touching the floor.
During the space walk a wrench suddenly flies away. It should have maintained the same momentum and velocity as the rest of the ship.
A gauge aboard the shuttle is briefly shown to be spelled "PRESSERE".
That's probably the Space Cajun language they often speak.

Joe starts a shower by running the water continuously, and he runs out. People who are in locations where water is scarce (such as the Navy) know enough to take showers without running it all the time. They briefly get themselves wet, turn off the shower, lather up, then turn on the shower again to rinse. Running the shower continuously is called a "Hollywood shower" and is rarely done since it wastes water.
