Seconds after Apollo 11 touched down on the Moon, Neil Armstrong announced: "Tranquility Base here, the Eagle has landed". This first informally, then later officially, gave a place name (although latinized) to the spot marked to this day by the Apollo 11 descent stage. Since that time, several other manned lunar landings have occurred, as have numerous robotic spacecraft landings on the Moon, Mars, and even Titan. Each of the non-roving landers effectively serve as place markers on their host worlds (and will for perhaps centuries or more); have place names been assigned to any of those sites e.g. "Pathfinder Station" or such? Was Tranquility Base a one-off, and if so, is it out of a matter of policy?
I am interested in named landing sites (locations named to essentially memorialize the landing event at that spot) at which an immobile artifact such as a lander, instrument package, etc. remains to "mark the spot". I would include artifacts such as the Viking and Pathfinder landers, Spirit, and Opportunity landers (despite being little more than platforms at the point the rovers were driven off). I would exclude resting locations of "debris" such as heat shields, backshells, parachutes, and "skycranes"; I wouldn't expect such locations to be worthy of naming.
