Although these are well-formed words in Spanish, the use of amartizar is discouraged because landing already refers to that action. According to the RAE, "said of an airplane or any flying device: to land after a descent maneuver, on solid ground or on any runway or surface that serves that purpose." In this definition the word earth appears as a common name, that is, as equivalent to "surface", to "soil", and not as the proper name of the planet: Earth. Therefore, it is not a question of landing on planet Earth, but of doing so on any track or surface, including those of aircraft carriers.
In reference to the arrival on Mars of the exploration robot Curiosity , some media use landing and landing, as in "The dimensions and weight of Curiosity do not allow landing to be carried out with the same techniques …", " Curiosity will dock on August 6." The appropriate thing, according to Fundeu, would have been to say: "The dimensions and weight of Curiosity do not allow the landing to be carried out with the same techniques …" and "The Curiosity will land on August 6".
