The SpaceX founder has made no secret of his ambitions to colonise planets in the solar system with human settlements. The founding principle behind the creation of his private space company was to make life multi-planetary. Last year in January he announced plans to send a million people to the Red Planet by 2050.
During an interview with Peter Diamandis in Cape Canaveral on Thursday, the Tesla billionaire cautioned that not everyone would “make it back” in the beginning.
He said: “Going to Mars reads like that advert for Shackleton going to the Antarctic.
“You know it is dangerous, it’s uncomfortable and it’s a long journey.
“You might not come back alive but it is a glorious adventure and it will be an amazing experience.”
He added: “Yeah, honestly a bunch of people will probably die in the beginning.
“It’s tough going over there.”
Mr Musk has plans to build 1,000 Starships over 10 years, which equates to 100 spaceships per year.
He has said that the ultimate goal is to launch an average of three Starships per day and make the trip to Mars available to anyone.
In a tweet last year, he wrote: “Needs to be such that anyone can go if they want, with loans available for those who don’t have money.”
He also promised those wishing to sign up to the venture that there would be a “lot of jobs on Mars”.
Mr Musk’s Mars mission has been criticised by leading scientists from around the world.
Lord Martin Rees, the UK’s top astrophysicist, recently described the idea as a “dangerous delusion”.
