The only thing I can think of is that the shuttle flies "upside down" in
orbit, and the top side is white while the bottom is black. Perhaps that
white side has a higher overall albedo than the ISS? Just a guess.

Does anyone have the official technical explanation of why the space shuttle
has been visually brighter than the ISS on these passes? Since the ISS is
much bigger, you'd think it would be the brighter of the pair.
