The issue has little to do with reflected sunlight. You can get a clear shot of stars while standing on the sunlit Moon, or floating in the Sun around the ISS. But you would need to adjust your camera for a nighttime exposure. That, of course, would massively overexpose any sunlit object also in the frame. If you had too much sunlit stuff in the field- the Earth, ISS, or Moon- that might produce enough scattered light inside the camera to reduce contrast somewhat, but that's still a secondary issue compared with exposure.

Here is a well answered question from a recent post regarding the moon in daylight conditions... the ISS is in a comparable environment as the moon relative to sunlight.

It was daylight on the Moon, so the camera exposures were set for daylight (short exposure times, small apertures). Set your camera for daylight and then take a picture at night; there won't be any stars. Stars are several orders of magnitude dimmer than a sunlit foreground. The only way you'd be able to see stars is if the foreground were completely overexposed (which the astronauts were taught to avoid doing, for obvious reasons).

Don't let the fact that the sky is black fool you into thinking it's night in this picture.

That's because you have a scientific mind 8) ... I have a lost mind

... so I am relatively disconnected from scientific methods.

I first saw it with an iodine atom attached - one "I"-ed.

Are the yellow hand rails for vision impaired astronauts?

I don’t know why they chose to finish the hand rails in yellow anodize but I expect it has to do with visibility as you mention… it may also have something to do with weight and cost.

Did you know that the white surface feature provides a low solar absorbance value? Helps keep things from heating up.

Moody Blues - Eyes of a Child,
“I'm gonna sit and watch the web
That you will build this day
Will it be a thread of love you weave
Is yours too short away
Then everything will be as you will see in the light

In the eyes of the child
You must come out and see
That your world's spinning 'round
And through life you will be
A small part
Of a hope
Of a love
That exists
In the eyes of a child you will see”

Won't qualify as a record in speed (race) walking, obviously both feet are off the ground.

I think space “walk” is one of those funny terms used to psychologically give us ground based folks terminology we are accustomed to when describing a something in a place where the majority of us cannot fully grasp the interacting skills required. Kind of like "Space Station"… when it is anything but roomy and stationary. But the word ‘station’ does provide some sense of stability when your world is hurtling 7.7 km per second 390km above your natural life support.

I watched this YouTube of the ISS flying across the Atlantic from 1,000 feet up... Although the video makes it look feasible, I couldn't help but see the friction, sparks, breakup, explosions, fragmentation and utter chaos in my minds eye.

You gotta watch out for them artists and their depictions...
