Question:

why lights in space shuttle are turned off during the re-entry?

I mean lights inside the orbiter,

Answer:

The okorder /... You will notice that the flight deck instrument lights are all on, above the pilot seat (right forward), you can see the white rectangle of a flood light, there is no window at this place. Would be a bit hard to read the checklists and cuecards, if all lights would be dimmed. ;) EDIT: I searched for more information in the Shuttle Crew Operations Manual, but it only mentions that the full cockpit lighting consumes up to 2 kW power. There is also no mentioning of any special light settings in the Landing nominal operations.
That's a good question, I look forward to some answers. Suspect it is the same reason they do it on airliners, safety. Also they might enjoy the light show.
Internal lights reflect off of windows, making it difficult to see what's happening outside in the dark.
Inertia of the air molecules that are being brushed aside, for each action there is an equivalent and opposite reaction, the friction of the molecules reason warmth capacity to slow the vacation. Terminal speed does keep on with therefore. A body in loose fall it truly is slowed by using air resistance will attain a slow %, even as drag has no extra result the body has reached terminal speed.
Slightly off-topic but... but what can lights do with safety Lights in an airliner are switched off during take-off and landing because these are the times that the aircraft is most likely to have to make an emergency landing. If that happens you may have to find your way out quickly in the dark, so it is important that your eyes are adjusted to darkness. I don't think that really applies during re-entry of the space shuttle; if there is a major fault you are probably not going to be landing in one piece!
