Here is a good depiction of the current configuration of ISS. I am assuming this is the normal "LVLH" (local vertical, local horizontal) attitude. http://spaceflightnow.com/station/stage5a/001221update/full.html Rob Maston wrote: >was glinting for Ed had a surface normal that was pointing >about 15 degrees aft of starboard, and about 45 degrees >down toward nadir from the horizontal.

During unlatching and deployment of these two sections (as seen on NASA TV) it was very apparent the high reflectivity, mirror-like surfaces of the radiators. You could easily see the astronauts image reflected back into his helmet-cam! The image shows them as a dull grey, but they are much more reflective. I will try to find exact dimensions. On the Progress panels - in the picture Rob referenced, I think he was speaking of the Soyuz. The Progress was not docked at the time of that photo. When compared to the above link you can see the Progress as it is currently docked. Note: after the next shuttle mission and final undocking of the Progress M1-4, the Soyuz will move to the nadir docking port and future Progress vehicles will dock at the end of the Service Module. (where the Soyuz is now) On the solar panels of Zaraya and Zevezda - I have not yet found confirmation if these panels are, in fact, NOT tracking the Sun. One can assume with the power requirements being met by the P6 solar arrays, these smaller panels are not needed, but may be tracking for redundancy.
