I'm not exactly sure what you mean, but empty space will remain black simply because it's empty, there's nothing to reflect the light.
I would have expected the sun to light up space all around.
Ice crystals initially remain ice crystals because of the extremely low pressure and very cold temperatures of space. Prior to entry, they do turn the left side of the orbiter toward the sun to melt any "waste ice" that may have formed from the liquid evacuation vent from the toilet. The crystals from the toilet have been known to reach sizes up to a foot, which could damage the Thermal Protection System of the orbiter if it broke off and went skidding down the protection tiles or thermal blankets in the aft portion of the orbiter, especially around the aft engine compartments. Such damage to the TPS would risk burn-through of the aluminum skin of the side walls of the orbiter. The sun exposure of the liquid vents requires a mimum twenty minutes to assure melting of the "icecicles." However, most of the melting occurs primarily at the metal seal while the main portion of the icecicle remains intact.

There are several things about space travel that I've always wondered about. Things that just don't seem to make any logical sense. I'm beginning to think we never did really go to the moon.
1) Did the first space suits really have no protection from radiation?

2) Why did the Lunar Module clearly not leave a blast crater?
109:23:38 Armstrong: I'm at the foot of the ladder. The LM footpads are only depressed in the surface about 1 or 2 inches, although the surface appears to be very, very fine grained, as you get close to it. It's almost like a powder. (The) ground mass is very fine. (Pause)
109:24:13 Armstrong: I'm going to step off the LM now. (Long Pause)
109:24:48 Armstrong: That's one small step for (a) man; one giant leap for mankind. (Long Pause)
109:25:08 Armstrong: Yes, the surface is fine and powdery. I can kick it up loosely with my toe. It does adhere in fine layers, like powdered charcoal, to the sole and sides of my boots. I only go in a small fraction of an inch, maybe an eighth of an inch, but I can see the footprints of my boots and the treads in the fine, sandy particles.
109:25:30 McCandless: Neil, this is Houston. We're copying. (Long Pause)
109:25:45 Armstrong: There seems to be no difficulty in moving around - as we suspected. It's even perhaps easier than the simulations of one-sixth g that we performed in the various simulations on the ground. It's absolutely no trouble to walk around. (Pause)
[109:26:16 Armstrong: Okay. The descent engine did not leave a crater of any size. It has about 1 foot clearance on the ground. We're essentially on a very level place here. I can see some evidence of rays emanating from the descent engine, but a very insignificant amount.
