Mars travellers will be Martians, not Earthlings: Astronaut
Former Canadian astronaut Chris Hadfield has said that future Mars-bound astronauts would need to consider themselves as Martians to survive. Hadfield, who has flown to space three times, said he would tell the crew, "We are no longer Earthlings, we are now Martians." "We need to redefine our relationship with the planet that birthed us," he added.
