The suns are the sources of light in space, so one assumes that the position of space station determines whether when astronauts having their space walk, they are in the sun light or in darkness? If the station is behind the planet, it is in complete darkness?

In the low-Earth orbit commonly obtained by the space shuttle and the ISS, it takes about 90 minutes to circle the Earth.
This means that every 45 minutes, there is a sunrise or sunset.
The astronauts go in and out of darkness all the time when they orbit the Earth. When it is "day" it can get pretty bright, when it is "night", it will get awfully dark.
I was watching part of the space walk which the astronauts were preforming on this most recent shuttle mission,
you could hear them talking about how long before it would get dark and needing to turn on the glove heaters and lights in order to continue working.

relies upon on what you recommend by using outer area. someplace interior the image voltaic gadget, there are different gadgets that reflect the image voltaic so that they could generate gentle. Plus the area isn't a complete vacuum, there are some molecules and mud debris round, even with the very incontrovertible certainty that i don't think of they could be seen to the interest. Stars don't have from now on some thing to do with this, as they do no longer reflect gentle. IF he were in an section with 0 gadgets interior of a comfortable twelve months, no dirt, purely distant stars, say in intergalactic area, and he might want to no longer see any component to his spacesuit, they maximum magnificent, he will see purely darkness.

The astronaut is in a void, surrounded by darkness - in darkness. Even when light shines upon them, the light does not illuminate the surrounding darkness.
Therefore, they are in darkness, although there are light sources, and the darkness is not complete.

The spacewalkers experience the dark side of the earth and the light side. Temperatures go from +120 degrees celsius to -100 degrees celsuis.
I figured you were asking about the shuttle pilots and their spacewalks.

Unless they are in geostationary orbit, same spot over a dot on the earth, they see the sun rise and set about every 45 minutes or more depending on their height from the earth's surface.

"If the station is behind the planet, it is in complete darkness?"

They are in the light, because the sun ray is near to them at that time.
