Aloha - Just a short note/comment -
The "Crater Chains" seen on the Mercury images, as well as on Lunar images are secondary craters - caused by the impact of ejecta from the initial impact. They head out radially from that initial impact. Occasionally you can find tertiary craters - from the impact of ejecta from the secondary impacts :-) :-) This is not to be confused with the idea of crater chains from a group of impactors that came from an initial object that fragmented - (or was impacted) at some time in orbit. (eg SL9) I would highly suspect "crater chains" of this nature would not be in close proximity to each other... Cheers - ted --- "E.P.
