Mars to stay missions propose astronauts sent to Mars for the first time should intend to stay.
 Unused emergency return vehicles would be recycled into settlement construction as soon as the habitability of Mars becomes evident to the initial pioneers.
 Mars to Stay missions are advocated both to reduce cost and to ensure permanent settlement of Mars.
 Among many notable Mars to Stay advocates, former Apollo astronaut Buzz Aldrin has been particularly outspoken, suggesting in numerous forums "Forget the Moon, Let’s Head to Mars!"
 and, in June 2013, Aldrin promoted a manned mission "to homestead Mars and become a two-planet species."
 In August 2015, Aldrin, in association with the Florida Institute of Technology, presented a "master plan", for NASA consideration, for astronauts, with a "tour of duty of ten years", to colonize Mars before the year 2040.
 The Mars Underground, Mars Homestead Foundation, Mars One, and Mars Artists Community advocacy groups and business organizations have also adopted Mars to Stay policy initiatives.
Buzz Aldrin, What Happened To You in All The Confusion?
 (Original title: "Buzz Aldrin, hvor ble det av deg i alt mylderet?")
 is a novel by the Norwegian author Johan Harstad, published in 2005.
 The book deals with a thirty-year-old gardener, Mattias, near obsessed with the thought of being second best, the greatest number two, much to his girlfriend's grievance.
 He looks upon astronaut Buzz Aldrin, the second man on the Moon, as his role model, and tries to live up to what he thinks Aldrin would do in any given situation.
 He has an extraordinary talent as a singer, but refuses to become a singer in his friend's semi-famous band, arguing that "not everyone wants to be a leader, some just want to be the secretary.
 Not everyone wants to star in a movie, some just want to watch the movie."
 After losing both his girlfriend and his job, he accidentally ends up on the Faroe Islands, where he meets people with the same ideals as himself, living in a psychiatric halfway house.
 Using the lunar-like landscape of the Faroe Islands as a backdrop, the novel deals with their attempt at finding a balance between being second best and anonymous without going into total isolation.
