I keep wondering: if we put them all at Oppy's current position, which one would be the first to reach Victoria's rim? I guess one should take into consideration not only the average speed (which I have never seen presented in a nice table for comparison) but also maneuverability and modes of navigation... -------------------- Neptune's 160th Anniversary: http://www.flickr.com/photos/56566887@N00/...57606142220219/

The ASSUMPTION that the lunar sky is perfectly black in the daytime is probably not true and indicates that even telescopes that are well-shielded from sunlight or lunar-surface reflected light will have lunar-dust-atmosphere interference during the day.
