Space Forum / Shuttle / August 2008

I think the answer is yes. Sometimes but not always. Remember, although
there are windows in the iss, there is no kind of  look out post manned. I
have heard comments about having seen  sun glint from the solar  arrays on
other sats, and a couple of sightings of moving points of light later
identified as old  bits of launch vehicles.

Its the ones you don't see which I imagine they worry about. There have been
strange noises from outside, and evidence of quite large glancing blows of
impacts of  who knows what on the outside during evas.

Sooner or later debris or mm particles will cause a serious problem, Its
just a matter of time. All you can do is protect as much as possible, track
the best you can and hope for the best. Its going to be a whole lot worse
for long stays on the Moon of course.
