The part of the outer space planet where the astronauts live has permanent sunlight (starlight) and they refer to the nearby star as "the sun" (i.e. there isn't more than one of them); so, one face of the planet must permanently face that one star for it to be permanent daylight (not a revolving system of two stars or more), yet when on flat ground, their shadows are not consistent lengths.
It's easily seen at 9:01 that there is no closing latch connected to the doorknob. It is a non-functional fake door.
The newborn shown at 3:42 is an obvious doll. The arm of the newborn sticks up stiffly like that of a doll. Also, the doll is way too large and long to be a newborn.
The female Human astronaut from Earth wears (has clearly packed) completely impractical shoes (high heeled slip-ons) to explore a planet, especially when outside the base.
