This is just the first of what will presumably be many new sets of names for features on Mercury produced by MESSENGER's imaging:
QUOTE Twelve New Names and a New Theme for Fossae Approved for Use on Mercury The following new names have been approved by the IAU for use on Mercury. Craters: Apollodorus, Atget, Cunningham, Eminescu, Kertész, Neruda, Raditladi, Sander, Sveinsdóttir, Xiao Zhao Rupes: Beagle Rupes Fossae: Pantheon Fossae The newly approved theme for fossae on Mercury is "Significant works of architecture." Beagle Rupes is the big curvy rupes near the western terminator on the outbound images. Pantheon Fossae is the "spider." Apollodorus is the crater that sits on the spider. Anyone care to try your hand at mapping out the locations of the other craters? They all seem to be on the outbound images, no surprise there. Name Lat Lon Diameter Raditladi 27.28 240.93 257 Xiao Zhao 10.64 236.21 23 Atget 25.65 193.93 100 Sander 42.59 205.6 50 Apollodorus 30.58 197.01 41 Sveinsdóttir -2.58 259.96 220 Eminescu 10.79 245.87 125 Cunningham 30.48 203.07 37 Kertész 27.44 214.06 33 Neruda -52.47 234.55 110 --Emily -------------------- My website - My Patreon - @elakdawalla on Twitter - Please support unmannedspaceflight.com by donating here.

Secondary cratering has been understood very well since the pioneering work by Gene Shoemaker in 1960 or so. The curtain of ejecta breaks up into debris strands, not always radial because some are produced by in flight breakup of rotating blocks. We see it around terrestrial explosion craters, lunar craters, Mars craters... and it is better expressed on Mercury because the higher gravity compared with the moon brings the debris down closer to the primary so there's less time for it to spread out and become irregular in appearance. Radial cracks are all but unheard of around impact craters.
