Looks like you caught Mercury in the frame too, at the bottom... 👍

Hi Chris, yes, good thanks; hope same for you. Plenty to keep me very busy!

Yes, ejecta clumps can form rows of smaller craters. Each particle in ejecta follows a parabolic curve over the surface, but together they form an expanding cone of material moving out from the crater during formation. First understood in 1960s when modelled with high speed gas guns fired in vacuum.

Almost certainly a coincidence in this case.
But, you can get rows of smaller craters formed when material gets thrown out of larger ones (secondary craters).
Also, there are some cases in the outer solar system of broken comets forming craters in a line, e.g. en.m.wikipedia.org/wiki/File:Ch...

Greyscale, but a colour version wouldn't look very different. The three M-CAMs that took these images are black and white engineering monitoring cameras.
The scientific visible/near infrared light camera, SIMBIO-SYS, will provide colour data when we orbit Mercury. www.cosmos.esa.int/web/bepicolo...
