Out of the applicants, Mars One said it will select a multi-continental group of 40 astronauts this year. Four of them -- two men and two women -- are set to leave for Mars in September 2022, landing in April 2023.
Another multi-continental group of four will be deployed two years later, according to the Mars One plan. None of them will return to Earth.
The astronauts will undergo a required eight-year training in a secluded location. According to the project site, they will learn how to repair habitat structures, grow vegetables in confined spaces and address "both routine and serious medical issues such as dental upkeep, muscle tears and bone fractures."
"What we want to do is tell the story to the world," Lansdorp said, "when humans go to Mars, when they settle on Mars and build a new Earth, a new planet. This is one of the most exciting things that ever happened and we want to share the story with the entire world."
