As many as 500 wannabe Scots astronauts have joined the race to form the inaugural flight crew as part of an ambitious £4 billion project to colonise the red planet.
Dubbed "most desired job vacancy in the world", the Mars One experiment attracted applications from more than 140 countries.
The search for the two men and two women who will blast off on the 210-day flight to Mars in 2022 was launched in April, with 78,000 people registering within just two weeks.
When applications closed on Saturday that number had almost trebled.
In the UK, an estimated 7000 people have applied to leave Earth forever and head off to conquer the final frontier.
The mission is the brainchild of Dutch entrepreneur Bas Lansdorp.
His team hopes to finance the huge cost of the operation through sponsorship and advertisement fees on a Big Brother-style reality TV show that will follow the epic journey of the would-be Mars astronauts.
From today, a selection committee will sift through the applications, choosing 50-100 candidates to go forward to the second round stage.
The public will then vote to choose the first group of four to send to Mars in September 2022.
