So far the object found on Mars has not survived crossing any Earth atmosphere, it can't be called a meteorite. But the Met Soc is certainly the entity entitled to decide what is going to be the new name for this object. my 2 cents Michel FRANCO ----- Original Message ----- From: "Jeff Grossman" <jgrossman_at_usgs.gov> To: <meteorite-list_at_meteoritecentral.com> Sent: Thursday, January 13, 2005 8:49 PM Subject: Re: [meteorite-list] Possible Mars meteorite! > If confirmed, it can be named, but won't need any special designation like > "Aresite"... it will simply be another asteroidal meteorite, this one > found on Mars.
